Essential Oil For Aphids
What are Essential Oils
If you’re looking for an organic and safe way to control aphids, essential oils can help.
Lavender grows best in USDA plant hardiness zones 5 and 6.
If you’re experiencing a problem with aphids, lavender oil is an excellent option.
The essential oils tested in this study had the most effective insecticidal activity, with some causing more than 80% mortality among GPA.
The highest mortality was caused by contact activities, and the lowest was at 2% and three percent.
The highest contact activities were found with black pepper, rosemary, and tea tree.
A composite of three or more oils had the most effective combined effect, with R2s ranging from 0.787 to 0.78.
Although some oils contain chemical ingredients, essential oils are safe for plants.
These oils can be used to treat aphids, but they won’t harm other plants or the environment.
It is important to dilute any essential oil you plan to use before applying it to your plants.
Make sure that you test the solution on a plant leaf or aphids to ensure that it doesn’t damage leaves or cause any harm to the aphids.
Aside from repelling aphids, essential oils can also attract beneficial insects to your garden.
Neroli, for example, is irresistible to bees, and other insects are drawn to the smell of rosemary.
It is also a butterfly attractant.
You can place essential oils on pots to attract bees and butterflies.
When using essential oil in your garden, be sure to choose the purest possible product.
Neem oil is another useful insecticide.
Neem oil is a powerful antibacterial, antifungal, and insecticidal, so it’s safe for both humans and plants.
It can also be added to dish soap or used as a replacement for it.
Properties of Essential Oils
A recent study has determined that citrus-derived essential oils have potent insecticidal properties.
Clove, citronella grass, and cinnamon essential oils, meanwhile, were found to have a lower LC50 at 1.36 uL/L of air.
The insecticidal activity of essential oils was determined by testing them against aphids using four different types.
In general, tea tree, rosemary, and eucalyptus were most effective.
Binary blends of the four essential oils were found to be less effective at killing aphids than their individual compositions.
The LC50 values for these binary mixtures were significantly lower than those for the individual oils.
Aphids are attracted to certain types of fruits, especially peaches and cherries.
To neutralize the effect of essential oils on fruit-fly attraction, you can add the scents of these fruits to your spray solution.
It is best to use pure essential oils that are chemical-free.
Lavender essential oil is one of the most popular essential oils for aphid control.
Lavender grows best in USDA plant hardiness zones 5 and higher, and lavender has an intoxicating aroma that repels aphids.
Mix it with water and spray problem areas daily.
If it does not work within the first day, repeat the application every day until the problem is solved.
You can even mix up lavender essential oil with water for more effective control.
For the study, cabbage leaf discs were individually sprayed with two mL of the test solution.
Each treated disc was placed on plastic Petri plates lined with Whatman No. 1 filter paper.
A single disc of each treated leaf disc was then covered with a fresh layer of moist paper towels.
Once these dishes were placed in the growth chamber, they were incubated for at least a week.
Cause of Aphids
If you’re worried about aphids, it’s important to find out the root cause of your infestation.
Aphids are small, soft-bodied insects that feed on plant sap.
Most species are green, although some species are also yellow, brown, or black.
Aphids congregate in clusters on the undersides of leaves.
They feed by sucking sap and creating a sticky exudate called honeydew.
The honeydew can grow into a sooty mold and turn black.
In addition to feeding on plant tissue, some species also inject toxins into plants and produce galls.
Aphids live in gardens and are common pests.
They feed on a variety of plants but tend to favor herbs.
Their long mouthparts puncture plant tissue and suck the sap.
Unfortunately, aphids can also spread disease and cause damage.
The aphid honeydew can also promote the growth of sooty mold.
Regardless of the root cause of aphid infestation, it’s vital to understand why these pests are bothering you and what can be done to combat them.
If you aren’t sure what to do, consider trying a solution that uses dish soap to attract and kill aphids.
This works especially well if you’re trying to keep aphids from spreading.
Aphids are often attracted to new and softer plants, and overwatering and overfertilizing can also make the problem worse.
If you decide to use pesticides, look for insecticidal soaps and vegetable-based oils.
These products will smother the aphids and kill them.
You’ll need to apply them thoroughly to infected leaves.
Another treatment for aphids is to remove them from your plants.
They can infest new plants, so spraying them with water is usually the easiest option.
But in some cases, aphids can spread to nearby plants.
You can also apply neem oil or insecticidal soap to kill them.
However, these products can cause damage to your plants, so make sure they are safe for your plants.
Aphids are not the only problem in your garden.
Most plants need a balanced ecosystem, which includes some beneficial insects that will help control the population of aphids.
When plants are stressed, aphids reproduce rapidly and can easily create a large colony in just a few days.
Aphids literally suck the life out of plants.
So the next time you see your plants wilting, remember to check your plants for aphids!
Best Essential Oil for Aphids
The most effective essential oil for aphids is lavender oil.
Lavender comes from the plant Lavandula, and its aroma is known to repel aphids.
The plant grows best in USDA plant hardiness zones 5 and 6.
Dilute lavender oil with water and spray problem areas every day until the infestation subsides.
Do not use full-strength essential oils on your plants, however.
They are highly toxic to plants, and they can harm the leaves and stems.
Using essential oils to control aphids is a great way to protect your plants from this common pest.
Garlic and eucalyptus essential oils are known to be effective at repelling aphids.
You can mix the oils in a mixture with water or soap.
The mixture will then kill aphids on contact.
This solution is completely safe to use on your plants and will not harm your plants.
Neem oil contains azadirachtin, a chemical that may be toxic to humans.
But neem oil is safe to use in diluted form to fight aphids and other pests.
You can mix two tablespoons of the oil with water to create a spray that kills adult aphids as well as larvae and eggs.
If you want to use this oil to prevent pests, make sure you use it early.
Another popular product to fight aphids is Dawn dish liquid.
It has several chemicals that are harmful to aquatic creatures.
Dawn also contains toxic ingredients and poses a threat to humans.
Murphy oil soap also contains chemicals and is rated “C” by EWG.
This isn’t an effective solution if you want to use an essential oil on your plants.
But be sure to always use a quality essential oil that is safe to use.
It causes about 80% mortality when used in small amounts on plants.
Its contact activities are highest at three to five times the amount used in a laboratory study.
In addition, these oils were highly effective against hard-bodied insects, including beneficial ones.
Insecticidal soaps can be purchased at local nurseries and online stores.
