Aldicarb

Appearance: Aldicarb is a white crystalline solid.

Aldicarb is approved by the USEPA for use by professional pesticide applicators on a variety of crops, including cotton, beans, and others. Aldicarb, a member of the carbamate class of chemicals, is an extremely toxic systemic insecticide. Used to control mites, nematodes, and aphids, it is applied directly to the soil. It is used widely on cotton, peanut, and soybean crops. In the mid-1980s, there were highly publicized incidents in which misapplication of aldicarb contaminated cucumbers and watermelons and led to adverse effects in people. In 1990, the manufacturer of Temik (aldicarb), announced a voluntary halt on its sale for use on potatoes because of concerns about groundwater contamination.

It is formulated as a granular mix (5 to 15% active ingredient) because of its toxicity. It is not compatible with alkaline materials and is noncorrosive to metals and plastics.
