Neem Oil can be used to manage chewing insects in your garden. However, you must make sure you purchase 100% Cold Pressed Neem Oil that has all its components. This pure Neem Oil has a compound called Azadirachtin. It is what kills chewing insects. A lot of the Neem Oil you see in stores is processed with all the major components removed. Yes it is Neem Oil but no it is not 100% Cold Pressed with all its components including Azadirachtin.
You don't need a lot to make basic sprays. I show you in my video how to make a spray for dealing with chewing insects like the Green Cabbage Looper or most chewing worms and how to add baking soda (sodium bicarbonate) or potassium bicarbonate to the spray to also help fight powdery mildew.
Neem Oil can separate like in the above picture. If you let it sit in warm water for about 15 minutes it will warm and blend back together. You can see how I do this in the video.
