Phosphamidon is an organophosphate insecticide that was marketed under the trade name of "Dimecron " until its producer voluntarily canceled production in 1990 (#PMEP). It was mostly used to combat mostly insects - aphids, stemborers, lygusbugs, leafhoppers, leaf miners, spruce budworm, beetles, thrips, codling moth, grasshoppers, mites, scale, bollworms, Mexican bean beetles, white flies, and others - on numerous plants including citrus and cotton crops, rice, and nuts (#PMEP and #INCHEM). It was mainly a systemic insecticide, but it also has slight contact insecticidal properties (#PMEP).
