• Product description :

  Common Name: Cymoxanil
  Chemical Name: 2-cyano-N-[(ethylamino)carbonyl]-2-(methoxyimino)acetamide
  CAS No.: 57966-95-7
  Formula: C7H10N4O3
  Molecular Weight:  198.18
  Action: Fungicide
  Physical and Chemical Properties: Pure cymoxanil is colorless crystal solid. Its melting point is 160 ~161 degree C . The density at 25 degree C is 1.31g/cm3, the vapor pressure 25 degree C (tested by the method of extrapolation) is 0.080mPa. Solubility(25 degree C, w/w): 1g/kg in water, 185g/kg in dimethyl formamide, 105g/kg in chloroform, 41g/kg in methanol, 2g/kg in benzene, <1g/kg in hexane. Cymoxanil is stable in neutral or weak acidic mediums, easier decomposition in the alkalic and sunlight conditions.
  
  Toxicity: Cymoxanil is low poisonous. Acute oral LD50 to rats is 1196mg/kg. Acute oral LD50 to cavy is 1096mg/kg. Acute percutaneous LD50 to rabbits is greater than 3000mg/kg. It has no irritation to skin and low irritant to eyes. No distinct cumulative toxicity is observed by feeding rats with cymoxanil 200mg/kg feedstuff for 14 days. LC50 (8days) to quails is 2847mg/kg. LC50 to mallard is greater than 10000mg/kg. LC50 (96hours) to rainbow trout is 18.7mg/L. Ames tests demonstrate cymoxanil has no mutagenicity.
  Application: Cymoxanil is a local systemic fungicide. It is effective to downy mildew and late(or early) blight on vegetable and fruit trees. When combined with other protective fungicides, e.g., Mancozeb,other formulations which contain the element cuprum, and so on, it can effectively prevent and cure diseases mentioned above and the effect may keep longer. The recommended dosage to control grape downy mildew and potato late blight is 100~120gAI/ha.  Cymoxanil can decompose rapidly in crops, e.g., the residues detected in grapes on the seventh day of the last application is only 0.1ppm after 8 times' application of 15g/100L dosage. Its half time in soil is shorter than two weeks.
