Detailed Cinosulfuron Description:
1) Appearance: colorless crystalline powder. 2) Melting point: 127.0 - 135.2oC (pure). 3) V.p.: <0.01mPa (25oC). 4) KOWlogP: 2.04 (pH 2. 1, 25oC). 5) S.g./density: 1.47 (20oC). 6) Solubility: a) In water: 120 (pH 5.0), 4000 (pH 6.7), 19000 (pH 8.1) (all in mg/L, 25oC) ; b) In acetone: 36000, ethanol 1900, toluene 540, n-octanol 260, n-hexane <1 (all in mg/L, 25oC). 7) Stability: a) Decomposes above the melting point ; b) No significant hydrolysis at pH 7 - 10; considerable hydrolysis at pH 3 - 5.
Applications: 1) Biochemistry: branched chain amino acid synthesis (acetolactate synthase or ALS) inhibitor. Acts by inhibiting biosynthesis of the essential amino acids valine and isoleucine, hence stopping cell division and plant growth. 2) Action: absorbed primarily by shoots and roots, and translocated to actively growing meristematic tissue. 3) Uses: applied post-emergence to control many weeds, including Alisma, Annaal Cyperus Eleocharis, Marsilea, Potmnogeton and Sagittarla spp., Monochoria vaginalis and Sphenoclea zeylanica in transplanted, directly seeded, wet-sown, water-sown, and dry-sown rice crops, at 20 - 80g/ha. Also used in tropical plantation crops. For full weed spectrum, may need to be combined with a grass herbicide in tank-mix or sequential treatment.
