Abstract
One or more agricultural active ingredients (such as fungicides or insecticides) are entrapped in polymeric matrixes to form particles having a diameter in the range from about 0.2 to about 200 microns. The particles are applied to soil, to seeds, or to plants and release the active ingredient(s) at a rate sufficiently low to avoid phytoxicity but at a rate sufficiently high to provide effective amounts of the active ingredient(s), preferably throughout the growing period of the plant.
