Thiodicarb is commonly used to protect agricultural crops from Lepidopterous pests, such as Beet armyworm, Corn earworm and Black cutworm. As an insecticide, thiodicarb is effective against eggs as well as larvae, although the latter must feed upon treated foliage in order to be controlled.

Thiodicarb is a carbamate insecticide and pesticide that consists of two methomyl groups linked by amino nitrogen through sulfur molecules. 

Thiodicarb acts as an insecticide against major Lepidopterous, and suppresses Coleopterous and some Hemipterous insect pests. Thiodicarb acts as an ovicide against cotton bollworms and budworms. Thiodicarb is used primarily on cotton, sweet corn, and soybeans. The remaining usage is spread among leafy vegetables, cole crops, ornamentals, and other minor use sites. There are currently 14 tolerances for thiodicarb. Application types for thiodicarb include aircraft (fixed-wing and helicopter), airblast sprayer, chemigation, groundboom, high- and low-pressure handwand, backpack sprayer, and belly-grinder spreader. Thiodicarb is formulated as a liquid, flowable concentrate, granular, pelleted/tableted, water dispersible granules, and wettable powder. There are no homeowner uses of thiodicarb. conton bollworm, thiodicarb
