The answer is yes, but there are some important considerations to keep in mind. In this article, we’ll explore the benefits and potential risks of mixing pyrethrin with neem oil, as well as provide tips for safe and effective application.
Whether you’re a seasoned gardener or just starting out, read on to learn more about this powerful pest control combination.
Can I Mix Pyrethrin With Neem Oil?
As mentioned earlier, it is possible to mix pyrethrin with neem oil for pest control. However, it’s important to note that not all oils can be mixed together, so it’s crucial to check the labels of both products before attempting to combine them.
If the labels do not prohibit mixing, then you can proceed with caution. It’s important to note that mixing oils on plants that are under stress from drought, heat, or disease or in very hot temperatures can increase the risk of phytotoxicity. Therefore, it’s best to avoid mixing these two oils in such conditions.
The rate at which you dilute Evergreen will depend on your application equipment, target pest, and area of application. Please refer to the product label for complete rates and application instructions.
Understanding Pyrethrin And Neem Oil
Pyrethrin and neem oil are two types of organic insecticides that are commonly used to control pests in gardens and crops. Pyrethrin is a contact insecticide that is derived from chrysanthemum flowers and paralyzes pests on contact. However, it may not always kill them, and therefore, it is often formulated with another insecticide to ensure complete control. On the other hand, neem oil is derived from the neem tree and has been used for thousands of years to control insect pests. Its active ingredient, azadirachtin, repels insects and reduces their ability to feed, disrupting their hormones and preventing them from reproducing.
Both pyrethrin and neem oil are effective against a wide range of pests, including aphids, flea beetles, and potato leafhoppers. However, they have different strengths and weaknesses when it comes to controlling specific pests. For example, Entrust (spinosad) is the most effective control option for flea beetles, Colorado potato beetle, cabbageworms, and alfalfa weevil. Azera (pyrethrin and azadirachtin) provides excellent control of green peach aphid, flea beetles, Japanese beetle, Mexican bean beetle, potato leafhopper, and cabbageworms. PyGanic (pyrethrin) is less effective than Entrust and Azera but still provides good control of green peach aphid, flea beetles, and potato leafhopper. The growth inhibition effects of azadirachtin in Neemix were particularly effective against larvae of Mexican bean beetle and Colorado potato beetle but was generally less effective in trials with insect infestations consisting mainly of adult stages.
When using pyrethrin or neem oil for pest control, it’s important to follow the label instructions carefully to ensure proper application rates and safety precautions. While both products are considered safe for humans and the environment when used correctly, they may require repeated applications to achieve complete control. Additionally, mixing these two oils may be possible but should be done with caution as some oils may not be compatible with each other or may increase the risk of phytotoxicity under certain conditions.
Benefits Of Mixing Pyrethrin And Neem Oil
When it comes to organic pest control, using a combination of pyrethrin and neem oil can provide several benefits. Pyrethrin is a natural insecticide that provides quick knockdown of pests, while neem oil has a broad range of effects on many groups of insect pests, acting as an antifeedant, insect growth regulator, repellent, sterilant, and inhibitor of oviposition.
By mixing these two oils together, you can create a potent and effective pest control solution that targets a wide range of insects. This combination can be particularly effective against soft-bodied insects such as aphids, whiteflies, and spider mites.
Moreover, using pyrethrin and neem oil together can provide a more sustainable approach to pest control. Both oils are derived from natural sources and are considered safe for use in organic gardening. By using these oils in combination, you can reduce your reliance on synthetic pesticides that can harm beneficial insects such as bees and other pollinators.
Another benefit of using pyrethrin and neem oil together is that they have different modes of action. Pyrethrin works by disrupting the impulses along the axons of neurons, resulting in paralysis and death of the insect, while neem oil acts as an antifeedant and growth regulator. By using these two oils together, you can target pests at different stages of their life cycle and increase your chances of success in controlling them.
Potential Risks Of Mixing Pyrethrin And Neem Oil
While mixing pyrethrin and neem oil can amplify the effectiveness of the pest control, there are potential risks involved. The synergy between these two oils can create an acidic or alkaline mixture that may burn plants. Moreover, it’s possible that the pyrethrins may not work in an oil base.
It’s crucial to use pyrethrin on a limited scale since large scale use of pyrethrins on lawns by individuals and lawn care companies in municipalities where pesticide by-laws have been passed could pose significant risks to human health and environment. Additionally, pyrethrins are toxic to common beneficial insects, so it’s important to use them selectively and avoid spraying the entire plant or bed.
Careful adherence to label instructions is essential since each brand will probably have its own directions for the product. It’s recommended to do a test spray first to ensure that the mixture does not burn plants.
Tips For Safe And Effective Application
When using a combination of pyrethrin and neem oil, it’s important to follow these tips for safe and effective application:
1. Thoroughly mix the oils: Neem oil will not readily combine with water and needs an emulsifying agent, like a mild dish detergent, to effectively mix the oil. Add 1 to 2 teaspoons of dish detergent to 1 gallon of warm (not hot or cold) water in your sprayer. Mix thoroughly before adding the pyrethrin.
2. Apply in the morning or evening: To avoid burning the plants, it’s best to apply the oil spray in the morning or evening when temperatures are cooler. Avoid spraying in the afternoon hours and when the temperature is above 80F.
3. Wet both sides of leaves: Some bugs hide on the underside of leaves. Thoroughly wet both sides of leaves with the spray to ensure maximum coverage.
4. Don’t store the mixture: The effectiveness of the mixture will reduce after 40 minutes of mixing with water and soap, so it’s best to use it immediately after mixing. Discard any remaining mixture after spraying.
5. Clean your equipment: The residue from neem oil can clog up the nozzle when dried, so make sure to clean your spray bottle or sprayer before storing it.
6. Be patient and consistent: Neem oil is an organic, natural product that takes time to completely get rid of pests. For infestations, apply the neem oil spray every 7 days until the bugs are gone. For preventative measures, soak the plants with neem oil spray at every 14-day interval.
By following these tips, you can safely and effectively use a combination of pyrethrin and neem oil for pest control in your garden. Remember to always check the labels of both products before attempting to mix them, and to use caution when applying oils to stressed plants or in hot temperatures.
Alternatives To Pyrethrin And Neem Oil Mixture
While pyrethrin and neem oil are effective pest control options, there are other alternatives that can be used in combination or on their own. One such alternative is diatomaceous earth, a powder made from fossilized microbes that shreds the bodies of crawling, hard-bodied insects such as ants, spiders, and slugs. It is important to note that diatomaceous earth only works when dry, so it needs to be reapplied after rain.
Another alternative is neem 7-way, a product made from neem oil and other plant oils such as clove and peppermint. This product works by paralyzing and suffocating soft-bodied insects like spider mites and aphids. Unlike neem oil, which can have a strong odor, neem 7-way has a more pleasant scent. It is also important to note that neem 7-way may not be as effective against all pests as neem oil.
Lastly, Xentari and Pyganic are two products that can be used in combination for caterpillar control. Xentari is a Bacillus thuringiensis product that specifically targets caterpillars, while Pyganic is a natural pyrethrin product. This combination can improve plant stands and the quality of vegetables such as tomatoes.
It’s important to remember that when using any pest control product, it’s crucial to follow the manufacturer’s instructions and use caution to avoid harming beneficial insects or plants.
