AbstractThis chapter describes clay-based formulations of pesticides, whose design was to solve environmental and economical problems. The chapter focuses on herbicides—the leading type of pesticide used. Herbicides are applied to fields to impede the growth of weeds. However, only a part of the applied amount is bioactive, a certain part remains attached to the soil and another part is leached out and migrates into ground water or undergoes surface migration. Thus, application of herbicides to the field causes serious water contamination, and can hurt neighboring crops. This problem is particularly serious with hydrophobic herbicides (acetochlor) and anionic herbicides (sulfometuron). Leaching of the herbicide requires higher amounts of the herbicides to be applied, which also enhances environmental problems. As production and uses of herbicides are increasing, the serious health and environmental problems posed by these toxic compounds must be controlled to minimize the harmful effects of these products
