Garden Essentials 16 oz Neem Oil

Neem oil is counted among the safest and non-toxic insecticides available in the market today and is used in over 100 pest control products. The oil is extracted from the seeds of the Neem tree (Azadhirachta Indica), native to South-East Asia. What makes the oil an effective insecticide is the compound called Azadirachin. Unlike other pesticides, the chemicals in Neem oil are first absorbed by the plant on which it is sprayed and then reach the body of the insect feeding on that plant. Once inside, these compounds affect the insects in many different ways–they restrict their feeding and mating habits, prevent the larvae from maturing, and sometimes, hinder the insect’s breathing. Garden Safe Neem Oil offers a product which works as an insecticide, fungicide, as well as a miticide. It is effective against a range of garden insects like aphids, worms, beetles, loopers, caterpillars, and mites. It also protects the plants against many fungal diseases including powdery mildew, rust leaf spot, needle rust, scab, and flower/tip/twig blight. This insecticide can be used as a dormant or delayed spray as well to target the overwintering of eggs on plants. Overall, it’s the perfect solution for organic pest control and can be used on vegetables, fruit trees, ornamental plants and more. It’s recommended to mix 2 – 4 tbsp of the concentrate in a gallon of water, and spray evenly.

Is Insecticide The Same As Pesticide?

Although similar in meaning, pesticide is a broader term used for chemicals that help protect against all kinds of pests like bacteria, fungus, weeds, and insects. Insecticide, on the other hand, is a particular type of pesticide that specifically targets insects, like mosquitoes, fleas, spiders etc. There are also pesticides for unwanted plants or “weeds”, which are known as herbicides.

Types Of Insecticides

There are different types of insecticides available today with varying levels of toxicity and effectiveness. An organic gardener will prefer an eco-friendly insecticide that doesn’t harm the plants and other useful insects. On the other hand, a homeowner facing an infestation might find a stronger and long-lasting insecticide a better fit.

Another important thing to keep in mind about insecticides is their chemical composition.

Eco-friendly insecticides usually have spinosad or pyrethrin as their active ingredient.

Spinosad is a substance naturally produced by soil bacterium via fermentation and is toxic for many types of insects including fruit flies and mosquitoes. Widely used on crops and ornamental plants, it readily targets the nervous system of the insects that touch or eat it.

Neem oil is also becoming popular as an eco-friendly insecticide. It’s taken from the seeds of the neem tree, and works great against many types of insects. The chemical compounds present in the oil affect the insect’s hormones as well as it’s feeding habits.

Pyrethrin is another natural insecticide and is obtained from chrysanthemum flowers. Like spinosad, pyrethrin also attacks the nervous system of the insect upon contact and causes paralysis followed by death. In lower concentrations, pyrethrin also works great as an insect repellent.

Pyrethrin is also used to create synthetic chemical insecticides like pyrethroids which are widely used today in everyday household as well as professional pest control. The pyrethroid-based insecticides and specifically created to boost their effectiveness and make them last longer. Some of the popular pyrethroids available today in the market are Bifenthrin, Permethrin, and Cyfluthrin.

Few Things To Keep In Mind

  1. Always wear protective clothing like gloves, long pants, and a full sleeved shirt, to ensure that no part of your body is directly exposed. Also wear a face mask and glasses to avoid the risk of inhaling the fumes or getting it in contact with your eyes.
  2. Instructions are your friends, so please make sure that you follow the dilution guidelines given on the label. You’ll notice that different compositions work better for different types of insects.
  3. It’s not recommended to store the diluted insecticide solution so prepare as much quantity as you need to be used in a single treatment cycle depending on the area that needs to be treated as well as how severely it’s infected. Overusing these chemicals can cause damage and pose a risk of contamination.
  4. When treating a garden, pull out any dying or infected plants beforehand so that they don’t attract pests or infect other healthy plants.
  5. Treating an infected area at the right time is often the deciding factor when it comes to effective and long-lasting pest control. For instance, when treating plants, vegetable patches, or a larger garden, spray the insecticides after sunset and especially when the pollinating agents are gone. These insecticides are often extremely toxic to bees. Also, avoid spraying on rainy or windy days. The wind disrupts the spray while rain washes it off which allows the insecticide solution to either seep through the soil and contaminate the groundwater, or act as a surface run-off and pollute other water bodies. Aquatic life is largely at risk from these insecticides, just like bees. So, it’s best to use these chemicals on a dry day.
  6. If you accidentally come in contact with the chemicals, make sure you wash the area thoroughly with soap and water. In case you develop a rash or any burning/itching sensation, contact your doctor immediately.
  7. Although a lot of insecticides are pet friendly, and some are even used to treat the beds used by pets to get rid of ticks and bedbugs, it’s important to let the solution dry before using the treated area.

So, take your time to understand the different pest control products available and choose one that best fits your needs. The right product used efficiently and in the correct composition can tackle the severest infestation and helps keep all those pesky nuisance pests away from your garden and home.
