zaSol WSP is a water-soluble, non-oil based insecticide and insect growth regulator containing the active ingredient azadirachtin, which is derived from the neem tree.  This organic formula is potent but also environmentally friendly and can be used up to the day of harvest.  Because it is not oil-based, it will not burn leaves or clog equipment.  It controls a wide range of insects, including leafminers, whiteflies, mealybugs, scale, aphids, thrips, psyllids, sawflies, caterpillars, weevils, borers, mole crickets, and other listed pests.   Recommended for use in and around gardens, vegetables, fruit trees, herbs, trees, shrubs, and turf.  Apply at the rate of 1-4 tsp. per gallon of water.  *See label for complete application instructions.
