• Description: Thiodicarb is a white crystalline powder with a slight sulphurous odour. Thiodicarb is stable in light and ambient conditions and unstable in alkaline conditions. Thiodicarb is a carbamate insecticide. Thiodicarb is commonly used to protect agricultural crops from major lepidopterous insect pests 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. Thiodicarb is formulated to include several liquid products and one powdered product that must be mixed with water before field application. Thiodicarb is reclassified as an RUP. Thiodicarb degrades rapidly to methomyl, which is already a restricted use chemical. Thiodicarb, 3,7,9,13-tetramethyl-5,11- dioxa-2,8,14-trithia-4,7,9,12-tetra-azapentadeca-3,12-di ene-6,10-dione (IUPAC), consists of colorless crystals, which are sparingly soluble in water, readily soluble in dichloromethane, acetone, methanol, and xylene. Thiodicarb is produced by reaction of N,N -thiobis(methylcarbamic acid fluoride) with 2-methylthioacetaldoxim in the presence of a base.
• Uses: Thiodicarb is used as an insecticide. Insecticide. Thiodicarb is an oxime carbamate insecticide and ovicide with both oral and contact activities against major Lepidoptera, Coleoptera, Diptera and Hemiptera pests in/on cotton, maize, fruits, soyabeans and vegetables.
