Identification
COMMON NAME: Triasulfuron (BSI, ISO draft).
Chemistry
COMPOSITION: 3-(6-methoxy-4-methyl-1,3,5-triazin-2-yl)-1-[2-chloroethoxy)-phenysulfonyl]-urea. CLASS: Sulfonylurea. PROPERTIES: Light brown granules; odorless. Melting point 186℃.
Environmental Guidelines
SOIL PARTICLE ADSORPTION: Adsorption to clay or soil colloids is relatively low, and thus leaching can occur. Further studies underway. WATER SOLUBILITY: 1500 ppm at 20℃ and pH 7.
