Biochemistry Cholinesterase inhibitor; activity is due to in vivo cleavage of the N-S bond, resulting in conversion to carbofuran.
Mode of action Systemic insecticide with contact and stomach action.Uses Control of a wide range of soil-dwelling and foliar insect pests. Examples of uses include control of millipedes, springtails, symphylids, wireworms, pygmy mangold beetles, frit flies, white grubs, aphids, caterpillars, flea beetles, Colorado beetles, stem borers, leafhoppers, planthoppers, codling moth, scales and free-living nematodes.
