While insects are a valuable part of our gardens' ecosystems, sometimes they end up tucking into our vegetable harvests or eating their way through our flower buds before they bloom. 

These moments can have us reaching for the insecticides. However, filled with toxic chemicals, commercial insecticides often stand at odds with the sustainable garden ideas that we want our plots to embody.

This is where homemade insect sprays and deterrents come into their own. Created from items you would find in your store cupboard, they are quick and effective ways to ward bugs off your prized plants. 

‘Homemade garlic, nettle, soap, tomato and basil sprays are effective against aphids, mites and thrips. The aim is not to kill off all the insects in your garden, but rather aim for a healthy ecosystem,’ says garden expert Leigh Clapp.

Bug sprays – 6 homemade recipes for plants

Homemade bug sprays should only be used as a short term solution – at the same time as treating pests, think of adding other plants to your garden that will encourage insects and animals that prey on the problem bug.  

‘Disaster-proof your garden through plant diversity. The wider the range of plants, the less they are plagued by pests, so that if a disease or pest occurs only a limited number of susceptible plants will be affected,’ continues Leigh. 

For example, if you want to get rid of slugs, can you attract more birds? If you need to get rid of aphids, could you plant angelica, fennel and dill nearby to attract ladybirds? There are lots of different companion planting ideas that will help you to reduce pests in your plot. By creating a balanced garden, you will find that you have less and less need for bug sprays. 

Before using any of these bug sprays on your plants, always do a patch-test. Spray a small amount onto a few leaves of the plant and wait 24 hours to see if there is any damage. Avoid using any foliar sprays during the heat of the day as the exposure to the sun can cause leaf burn. 

1. Insecticidal soap

A popular bug spray for treating a wide range of pests, homemade insecticidal soap, consists of soap, oil and water. Homemade insecticidal soap is often the first port of call for many gardeners as the ingredients are all store cupboard essentials. 

To create insecticidal soap combine one cup of vegetable oil with one tablespoon of dishwashing soap or pure Castile liquid soap. For this method, as well as any others that call for dishwashing soap, avoid those that contain a degreaser or bleach as these can cause more harm than good. Use this oil and soap mixture as a concentrate and dilute one teaspoon with two cups of warm water into a spray bottle. Once mixed with water, the solution’s efficacy will only last for a day. 

Insecticidal soap is one of the best ways of getting rid of aphids, as well as lacebugs, leafhoppers, mealybugs and thrips.

2. Neem oil bug spray

An organic insecticide, neem oil has seen a rise in popularity as a method to treat everything from insects through to fungi. 

‘Neem oil has been used in India for thousands of years and is a trusted method to keep on top of pests, without any of the nasties,’ explains John Maree, co-owner of OxyPlants . ‘A spray of Neem oil on the tops and undersides of your plant’s leaves will help remove several pests, including mites, whitefly, aphids, thrip, and mealybugs, at every stage in their life cycle. Using neem oil also helps to get rid of powdery mildew, too.’

To use neem oil as a homemade bug spray mix one to two tablespoons of pure, cold-pressed neem oil with a gallon of water. You can also add one to two teaspoons of dish soap to the mix to help the neem oil adhere to the plants. 

Alternatively, you can use neem oil as a root soak to treat root rot. Mix one gallon of water with two tablespoons of neem oil and one teaspoons of pure Castile liquid soap (to help the neem oil adhere). Apply a small amount as a test and wait 24 hours. If all is well, then apply two or three cups to the soil around the plant, then continue the treatment as a replacement to the watering cycle. 

A benefit of using neem oil over other pesticides is that it doesn't harm birds, pets or beneficial insects. This is because neem oil gets absorbed into the plant’s tissue rather than just sitting on the surface and so only affects any insects that ingest the plant. 

3. Vinegar spray

It seems that there is no end to the abilities of vinegar, especially when you take into account the numerous ways of cleaning with vinegar, but did you know that it can also be used as a bug spray?

One of the easiest homemade bug sprays, simply mix one cup of white vinegar with three cups of water. You can also add half a teaspoon of dishwashing soap to help the solution adhere. Shake thoroughly and apply to the affected areas.

The acetic acid in the vinegar will treat a wide range of garden pests but it requires contact. If you have whitefly eggs be sure to spray under the leaves. Furthermore, white vinegar has a strong odor which has been reported to repel ants and other scent driven pests.

'If you are wanting to treat houseplants with a vinegar spray, try adding a few drops of essential oil or some slices of lemon peel or rosemary sprigs to help temper the vinegar smell,' advises Period Living editor Melanie Griffiths.

4. Garlic spray

You may have heard that onions and garlic make good companion plants as the scent of their foliage helps to repel aphids, slugs and carrot fly. This spray takes it to the next level. 

‘Puree two garlic bulbs with one tablespoon of vegetable oil, let it sit overnight, strain, add one teaspoon of mild liquid soap and four cups of water to fill the spray container,’ recommends Leigh Clapp. 

Store this mixture in the fridge until needed. In the evening, spray both sides of the leaves with the spray and then reapply every few days when your plants are suffering with infestation. Alternatively, use every one to two weeks as a deterrent. 

If you want to be even more sustainable, why not learn how to grow garlic so that you can have an endless supply of garlic spray – plus extra cloves that you can add to your favorite meals?

5. Tomato leaf spray

If you’ve ever tried growing tomatoes, you will be familiar with the characteristic scent of their leaves, but did you know that these leaves contain a compound called alkaloid which can be used to create a spray that is toxic to aphids and mites? To make a tomato leaf spray, mix equal quantities of chopped up tomato leaf with water and leave to steep overnight. Let this steep overnight, before straining into a spray bottle and applying to the plant’s leaves.

This is a great way to recycle tomato leaves once you've pruned them – you can learn how to prune tomato plants for a maximum yield.

6. Cinnamon spray

If you’ve ever grown plants in pots, you’ll be familiar with the problem of stray mushrooms. However, this can be easily resolve with a simple cinnamon spray. Mix two teaspoons cinnamon powder into four cups of warm water. Allow this to steep overnight and then strain through a coffee filter and then pour into a spray bottle. Mist the potting soil and plants. 

Cinnamon spray is also reported to be an effective treatment to get rid of ants. If you have an ant problem in your pots or want to keep ants away from dining or patio areas, try applying cinnamon oil or powdered cinnamon to create an effective barrier.

What is a natural bug killer for plants?

Vinegar is a really effective natural bug killer for plants. Dilute it 1:1 with water in a spray bottle and spray it over and under the leaves of affected plants. You can also use it around the house to deter bugs inside; the vinegary smell will quickly dissipate.

You can also use a hydrogen peroxide and water solution, which is great when trying to get rid of bugs from houseplant soil. 

Which homemade bug spray is best for repelling mosquitoes?

The best homemade bug sprays for repelling mosquitoes are those with a strong smell that mosquitoes hate. Other than citronella, which you are probably already familiar with as a mosquito repellent, they include the following essential oils:

Organic garden pest control is on the minds of many gardeners these days. Natural home pesticides are not only easy to make, they are cheaper and safer than many products you can buy on store shelves. Let’s take a look at some natural insect repellents you can make for the garden.

The best way to make natural pesticides is to use natural products that you have laying around your house. Garden pests are repelled or killed by a surprising number of safe and natural products. Here are a few natural insect repellent recipes:

Organic Garden Pest Control Recipe #1

Peel the garlic cloves and puree the cloves along with the oil and water. Allow to sit over night and then strain the mixture. Add the soap and mix toughly. Pour into a spray bottle and use on pest infected plants.

Organic Garden Pest Control Recipe #2

Combine ingredients and pour into a spray bottle. Use this organic bug spray on your affected plants.

Organic Garden Pest Control Recipe #3

Puree peppers and water. Let sit overnight. Strain carefully (this will burn your skin) and mix in dish soap. Pour into a spray bottle and spray this organic bug spray on your buggy plants.

Natural home pesticides are exactly like chemical pesticides in one very important way. Organic bug spray for plants will kill any bug it comes in contact with, whether a pest bug or a beneficial bug. It is always best before mixing up any natural insect repellent recipes to think hard about how much damage pests are really doing to your garden.

You may be doing more damage to your plants by killing the bugs than the bugs were doing to your plants.

BEFORE USING ANY HOMEMADE MIX: It should be noted that anytime you use a home mix, you should always test it out on a small portion of the plant first to make sure that it will not harm the plant. Also, avoid using any bleach-based soaps or detergents on plants since this can be harmful to them. In addition, it is important that a home mixture never be applied to any plant on a hot or bright sunny day, as this will quickly lead to burning of the plant and its ultimate demise.

TOP-7 effective means for pest control in the garden. July 21, 2022 Kuban News

Every year there are more and more insect invasions and this one is no exception.

July - it's time to fight for the harvest, so as not to be left with a nose by autumn.

At first, everyone resorts to folk remedies, like vinegar and ash, but then they realize that they are not enough - insects continue to spoil the garden and garden. Now many products are being produced, both natural and chemical, in the review there are both. However, taking into account the latest State Duma statements about the massive counterfeit of chemicals that poison products, it is better to use natural organic substances.

This review is based on feedback from summer residents and gardeners from social networks and forums and is based on real experience. So, what means really help to fight pests.

1. O! GRASS

An organic bioinsecticide from a Russian manufacturer is praised for its quick and effective effect on pests such as thrips, aphids, Colorado potato beetle, spider mites, whiteflies and many others. Most of the reviews are related to the successful processing of seedlings of tomatoes, cucumbers, potatoes, strawberries. Users also noted that the drug quickly removes ants. The product is absolutely safe for people, animals and birds, as it is made from natural pyrethrins substances that are not related to chemistry.

2. Aktara

Swiss remedy for insects and their larvae. It copes well with weevils, fleas, thrips, bedbugs and other pests. The only negative is that the drug is not suitable for owners and neighbors of beekeepers, as it is toxic to bees. For humans, the drug is not dangerous, as it does not accumulate in the fruits of plants.

3. Zemlin

Protects against pests living in the soil. Vegetable crops are the most difficult to protect, since soil pests are simply not visible. This insecticide, according to summer residents, does an excellent job with wireworms, beetle larvae, as well as onion and cabbage flies.

4. Commander

Used mainly against the Colorado potato beetle to save potatoes. In addition to beetles, it acts on aphids, mites and leaf beetle caterpillars. Summer residents note a long period of action of the drug - up to 1 month. Among the shortcomings, it must be said about the danger of the product for birds, bees and earthworms.

5. Karfobos

Protects from garden ants. Vinegar, boiling water and other means are unlikely to help with them in the way that a special preparation will do. It is rapidly eliminated from plants and soil, but only works through direct contact with insects. Of the minuses, only the effect of addiction was described with prolonged use.

6. Lepidocide

Biological agent based on enzymes and microcrystals. Effective against caterpillars, codling moth, whitefish, moth, sawfly and even moths. The insecticide is safe for the environment and does not pose a danger to humans. Only affects insects. It can be used at any stage of growing tomatoes, cucumbers, cabbage and other fruit plants. Since the active ingredients are components of bacteria, the drug is designed for a short shelf life. As most insecticides break down quickly in the sun, it is best to spray early in the morning or evening.

7. Tabazol

Not only an insecticide, but also an excellent fertilizer. Tobacco dust and wood ash nourish plants and repel harmful insects. The drug is harmless to humans and animals, and the effect on parasites occurs instantly. The term of protection of plants reaches 10 days, but passes after rainfall, therefore, after rain, re-treatment is necessary. The most important plus of tabazole is the naturalness of its components.

Orchard insecticides list of apple orchard protection products

Syngenta for apple orchard protection can offer a range of well known fungicides and a complete portfolio of insecticides, including novelties, for the control of dominant pests.

The main apple disease in Russia is scab ( Venturia inaequalis ). Starting from the green cone phase, it is necessary to protect the growing vegetative mass, which will become infected with scab ascospores from pseudothecia developing on fallen leaves.

At the beginning of the growing season, one or more treatments with copper preparations are used to reduce the stock of overwintering infection and to control scab.

Further, it is recommended to use the fungicide HORUS, which is able to systemically penetrate into the leaf mesophyll, spread evenly over the leaf even at an air temperature of +5°C and protect the plant from disease for 7–14 days. The dosage of the drug is 0.2–0.35 kg/ha. HORUS has a healing and protective effect, it is not phytotoxic for trees.

By applying HORUS at the beginning of flowering, we also protect trees from powdery mildew (all varieties except those susceptible to this disease), alternariosis, fusarium, gray rot and moniliosis.

After infecting an apple tree with ascospores, closer to flowering, the conidial stage of development of the scab pathogen ( Fusicladium dendriticum ) is formed on the leaves. From this moment until the end of ascospore dispersal, infection with both types of spores, the so-called. mixed infection. In such conditions, it is recommended to use the fungicide SKOR - the best drug for use during flowering.

At a dosage of 0.35 l/ha, it protects not only against scab, but also against monilial burn, Alternaria, powdery mildew. During the period of mixed infection, subject to prolonged leaf moistening and temperatures and air humidity favorable for the development of the disease, intervals between sprayings of more than 7 days are unacceptable, since during this period new shoots and leaves are actively formed that require protection.

Starting from the “flowering” phase and further as the fruit grows, the SCOR preparation can be applied up to four times. It is very important to properly and effectively protect the apple orchard until the “walnut fruit” phase, after which the infection will be more of a conidial infection, which is somewhat easier to deal with, including contact fungicides.

In addition to the main disease of the apple tree - scab - powdery mildew ( Podosphaera leucotricha ) is very harmful on some varieties. Treatments for this disease before flowering with specialized fungicides are usually carried out on varieties susceptible to this disease, such as Idored, Jonathan, Stark John Grimes and others.

Pruning initially reduces powdery mildew infection in these varieties because the pathogen overwinters in dormant buds.

Chemical treatments for this disease at the beginning of the growing season, in the phases of "green cone" - "pink bud", it is advisable to carry out the drug TIOVIT JET (800 g/kg of sulfur), which will preventively control the disease. The optimal dose of the drug in this period is 4.0–6.0 kg/ha. On apple varieties that are weakly susceptible to powdery mildew, it will be enough to use the drug HORUS.

Further in the growing season, it is possible to use a specialized fungicide to combat powdery mildew - TOPAZ at a dosage of 0.3-0.4 l/ha.

In the second half of the growing season, on varieties with different susceptibility to fight powdery mildew, it is possible to use the drug TIOVIT JET, which will control the disease at a level of 80%, and also restrain the development of mites. The optimal dose of the drug is 5.0–8.0 kg/ha, depending on the phase of fruit development and the sensitivity of the variety to sulfur. TOPAZ, a specialized fungicide for powdery mildew control, is usually applied before flowering, but, in rare cases, on varieties susceptible to powdery mildew, it can be applied at a dosage of 0.3-0.4 l / ha throughout the growing season.

If HORUS was used once per season, treatment with this product 2 weeks before picking apples has a good effect in combating storage diseases.

Among the pests of the apple tree, moths that damage the buds, apple sucker, apple flower beetle, goose, etc. are the first to appear. To suppress the complex of harmful organisms, the drug KARATE ZEON is used at a dose of 0.1–0.4 l/ha (depending on the species composition of pests ). To control the apple flower beetle in the “budding” - “pink bud” phases, the best option would be to use the AKTARA insecticide at a rate of 150–300 g / ha, since it will provide long-term protection not only against weevil, but also against aphids, apple sawfly and apple sucker .

In the “pink bud” phase in the apple orchard, there is a complex of pests: aphids, leafworms, weevils, sucker, California scale insects, mites, etc. This is the time to apply the general-exterminating organophosphorus insecticide DURSBAN at a dosage of 2.0 l/ha.

Of course, the main apple pest in Russian orchards is the codling moth, so the integrated system of protection against orchard pests is based on the fight against it. Since this insect damages only the fruits of the apple tree, the appearance of the pest falls on the period before flowering / at the beginning of the flowering of trees.

To combat the first generation of codling moth , when you can clearly track the beginning of flight, the use of INSEGAR ovicide, which has no analogues in Russia, at a rate of 0.6 kg/ha, has an excellent effect. The insecticide is applied 5-10 days after the capture of the first male codling moth, as a rule, this is the “end of flowering” phase. Orchards should be treated with the contact preparation INSEGAR before the laying of the pest - only under this condition will the maximum effectiveness of the application be achieved, namely, the complete death of the eggs. INSEGAR is approved for three applications per growing season and can be used for the first treatments on each of the three generations of codling moth, of course, provided that the flight of males is clearly monitored.

Codling moth oviposition. Orchards must be treated with INSEGAR contact preparation before the pest starts laying!

For treatments for each of the generations of the codling moth, a single treatment with an insecticide is not enough, therefore, after the INSEGAR preparation, another insecticide is used, also hormonal, of biological origin, but from a different chemical class - MATCH at a dosage of 1.0 l/ha. The drug has a contact effect on the oviposition of the pest, but its main effect is on caterpillars during intestinal penetration. MATCH is a translaminar insecticide, the effectiveness of which does not decrease when exposed to high positive temperatures and heavy rainfall.

Often the weather makes adjustments to the possibility of treatments, and you want to have a product with flexible application times. The Syngenta company has such a product in its garden portfolio - LUFOX.

LUFOX is a combined insecticide containing two active ingredients: fenoxycarb and lufenuron. LUFOX, like INSEGAR, blocks the hatching of caterpillars from eggs and the process of turning caterpillars into pupae, and also has a transovarial effect - it leads to a decrease in the fecundity of Lepidoptera females in subsequent generations.

Thanks to the second active ingredient, lufenuron (MATCH), LUFOX acts on freshly laid pest eggs and caterpillars of all ages. Thus, the drug affects lepidoptera pests throughout their entire life cycle, so LUFOX can be used from the beginning of the flight of butterflies until pupation. The ideal application window is before the first oviposition and before the start of mass hatching of caterpillars.

The period of protective action of LUFOX due to two active ingredients can exceed 15 days, therefore, a single application of LUFOX in hot weather provides protection for the fruit for a period equal to two treatments with any drug that affects the nervous system of the insect (classical insecticides: FOS, pyrethroids, indoxacarb, methomyl).

LUFOX can be applied up to three times per season at a dosage of 0.8-1.2 l/ha. If the agricultural producer puts this product in the protection system after INSEGAR treatment, that is, for the second treatment according to any of the codling moth generations, the dosage will be 1.0 l/ha. If LUFOX is used for the first treatment for any generation of the pest, then it is better to use the maximum dosage - 1.2 l / ha. The effectiveness of LUFOX is stable at high temperatures.

Other harmful Lepidoptera, such as leaf rollers and moths . Of the leafworms, the most common and harmful are the bud, fruit changeable, subcrustal, etc. Of the moths, the most harmful are the upper-sided and lower-sided mining moths, the hawthorn circle moth and the crumbly apple moth. These pests damage leaves, buds, buds, flowers.

To combat these insects, it is necessary to use, first of all, drugs that can penetrate the vegetative organs that insects feed on, that is, suppress them intestinally. According to these pests, it is advisable to use MATCH and LUFOX preparations in appropriate dosages. INSEGAR can be used to destroy the pest's egg-laying.

Often, treatments with these products against codling moth effectively suppress some types of moths and leafworms that develop in parallel. However, some of the species, according to the biology of the pest, may appear in early spring, during the period from "bud break" to the "rosebud" phase, and then these products should be applied before the appearance of the codling moth.

For the control of mites in the apple orchard , the bio-based insecticide acaricide VERTIMEC has proved its worth. One of the key advantages of VERTIMEC is that within two hours after treatment, it penetrates into plant tissues and forms inside a kind of reservoirs containing the active substance. These reservoirs provide long-term residual activity against mites.

After feeding on a substrate containing the active substance, pests are quickly paralyzed, that is, the main method of influencing the pest is intestinal. VERTIMEC is invulnerable to precipitation, ultraviolet radiation and temperature fluctuations, which allows for a period of its protective action of more than 15 days (up to 30 days when applied before the pest reaches the EPV). With an increase in temperature, the effectiveness of VERTIMEC does not change. On the leaf surface, the remnants of the drug are completely destroyed after 2 hours, which makes it possible to use it in systems using entomophages.

VERTIMEC at a dosage of 0.75-1.0 l/ha is used to control all species of spider mites and four-legged mites that damage fruit crops.

Syngenta is constantly updating its portfolio of horticultural preparations. In the 2013 season, the insecticides PROCLAME (a preparation of biological origin with a short waiting period for the control of lepidoptera pests) and VOLIAM FLEXI (controls almost all phytophagous insects in the garden) were registered in Russia.

Insecticide PROCLAME is a preparation for protection against caterpillars of lepidopterous pests (leafworms, codling moths, cutworms, moths) based on a new active substance - emamectin benzoate from the class of avermectins.

PROCLAYM, like VERTIMEK, penetrates into plant tissues within 2 hours and remains there for a long time. The period of protective action against lepidoptera pests of the garden is more than 14 days. When the temperature rises, the effectiveness of PROCLAYM does not change. On the leaf surface, the remains of the drug are completely destroyed after 2 hours. PROCLAME was registered on an apple tree at a consumption rate of 0.4–0.5 kg/ha.

PROCLAIM has an ovicidal effect: if the drug gets on the egg, the larva either does not come out of it, or dies when it gnaws through the egg shell. Therefore, the highest efficiency of PROCLAME is achieved if treatments are started before the caterpillars leave the eggs - the time from mass oviposition to the first hatching.

VOLIAM FLEXI is a complex insecticide containing two active ingredients: chlorantraniliprole (100 g/l) and thiamethoxam (200 g/l), belonging to different classes, complementing and enhancing each other's action. Thanks to this combination, VOLIAM FLEXY controls almost all insect pests of the apple tree:

VOLIAM FLEXI is a ready-to-use preparation with a wide spectrum of action that suppresses almost all insect pests, which allows solving the problem of their mixed species composition.

VOLIAM FLEXI is a flexible product. In case of precipitation even of a shower character, 1 hour after treatment, its effectiveness does not decrease, re-treatment is not required. VOLIAM FLEXI can be used in a wide temperature range: the effectiveness after absorption of the active substances by the plant does not depend on the air temperature.

After application of VOLIAM FLEXY, lepidoptera caterpillars stop feeding within 1–4 hours; sucking, beetle and dipterous pests - 15–60 minutes after the insect enters the body. The death of insects occurs within 2–72 hours, depending on the type of pest, but feeding stops immediately after the pests have absorbed the active substances.

VOLIAM FLEXI is easy to use. Liquid preparative form allows you to easily measure the required amount of the drug. The risk of errors when refueling the sprayer and the cost of manual labor are reduced.

Since VOLIAM FLEXY suppresses almost all insect pests, there is no need to mix preparations of different chemical classes. Before VOLIAM FLEXY appeared on the market, preparations from the classes of organophosphorus compounds and carbamates had the widest range. Compared to them, VOLIAM FLEXI has a greater activity and duration of action, especially against lepidopteran pests. VOLIAM FLEXI is used in smaller (4–10 times) dosages, so less storage space is required to store the drug, and fewer empty containers remain.

In addition to all of the above, VOLIAM FLEXY has a short waiting period (the period from processing to consumption of products), is not dangerous for personnel and the environment. VOLIAM FLEXI is incompatible with mineral oils and preparations based on dimethoate (physical incompatibility).

In 2009, the Syngenta company registered in Russia IZABION, an organic fertilizer for use on fruit, vegetable, flower crops, potatoes and grapes. ISABION is a biological stimulant widely used on almost all crops in Europe, Latin America and Asia. IZABION is used to increase the yield and quality of fruits and berries of fruit-bearing plantations, as well as to root seedlings and as an antistress agent.

In practice, IZABION until the “flowering” phase is used primarily to overcome stressful situations: planting seedlings, cooling heat, drought, frost, hail, phytotoxicity caused by the use of PPPs, etc.

Application of IZABION in a dose 2.0–4.0 l/ha before or at the very beginning of apple blossom regulates and stimulates the formation of flower and vegetative buds.

The use of IZABION in the second half of the growing season allows you to increase the yield and quality of fruits and berries of fruit-bearing plantations, the yield of marketable products, the content of calcium in fruits when used together with calcium fertilizers.
