Neem Oil (Azadirachta indica)
Neem oil is used in agriculture as a natural alternative to synthetic pesticides. The compound Azadirachtin is largely responsible for this action. When you fail to control pest and disease with companion planting and our natural plant oil based pest control concentrates, its time to consider Neem Oil. Neem oil is a great method of natural pest control, however as it leaves an off tasting residue, so should not be used within a few weeks of harvesting your herbs.
Neem oil can also be diluted to use on your skin as an insecticide. There is nothing more annoying than trying to carry out a delicate job on your plants when a mossie or six get you from behind.
Usage: Neem oil is extremely concentrated. Dilute to 5% in warm water in a spray bottle. Apply at night just before sunset. Test on a small area of your plants first and wait and see the reaction. You may need to use a few nights in a row for bad infestations.
