        Tribenuron methyl Chemical Properties,Uses,Production

        Uses

        Methomyl is a broad spectrum carbamate insecticide with both contact and oral toxicity to control chewing and sucking Lepidotera, Homoptera, Coleoptera and Hemiptera pests in vegetable, orchard, vine and field crops.

        Definition

        ChEBI: The methyl ester of tribenuron.

        General Description

        Colorless crystals. Non corrosive. Used as an herbicide.

        Air & Water Reactions

        Hydrolysis occurs rapidly at pH <7 or >12.

        Reactivity Profile

        A sulfonylurea derivative.

        Agricultural Uses

        Metabolic pathway

        The chemical structure of tribenuron methyl possesses a mono-N-methyl group in the sulfonylurea linkage which is a unique sulfonylurea herbicide and undergoes complex degradation reactions in the environment. Tribenuron methyl degrades into many degradation products, as indicated in the pathways by photolytic and hydrolytic chemical reactions and by biological degradations by mammal, plant, and soil. It is interesting to note that photolysis in different solvents yields diverse products depending on the individual solvents.

        Degradation

        Methomyl (1) was hydrolysed under alkaline conditions at 25 °C (DT50 ca. 14 days) and was stable under neutral to acidic conditions [DT50 > 30 days at pH 5 and 7 (Friedman, 1983)l. Cleavage of the carbamate ester bond is the primary degradation pathway, yielding S-methyl N-hydroxy-thioacetimidate (2).
        Irradiation of methomyl in dilute aqueous solution at 254 nrn yielded acetonitrile (3), dimethyl disulfide, acetone, N-ethylidenethylamine and carbon dioxide (Freeman and Ndip, 1984). Methomyl does not absorb sunlight but underwent degradation to acetonitrile by indirect photolytic reactions in/on soil surfaces (Swanson, 1986).
