Neem oil is an all purpose insecticide, miticide, and fungicide for organic gardening. Derived from the neem seed, neem oil is an excellent choice for use on virtually any plant, including roses, flowers, vegetables, herbs, spices, houseplants, trees, turf, and shrubs. Kills all stages of insects - eggs, larvae, and adults. It makes a great dormant spray and imparts a healthy shine to leaf surfaces.
