  COMMON NAME: Carboxin CHEMICAL NAME: 5,6-dihydro-2-methyl-1,4-oxathiin-3-carboxanilide STRUCTURAL FORMULA PHYSICAL AND CHEMICAL PROPERTIES Carboxin technical is light yellow powder.Its melting point is 91.5°C-92.5°C(single crystal),98.5°C-100°C(double crystal).The vapor pressure at 25°C is 0.025 mPa.The density is 1.36g/cm3.The solubility at 25°C:0.199g/l in water,177g/L in acetone,353 g/L in dichloromethane,92.5g/L in acetic acid,88g/L in methanol.Stability:when carboxin is under the sunlight,the DT50 is shorter than 3h in water solution (pH=7).Carboxin does not hydrolyze at normal temperature in solutions which pH value is 5,7 or 9.The DT50 is about 24 hours in soil.Carboxin can be combined with many pesticides except those are alkali or acidic. TOXICITY Acute oral LD50 to rats is 3820mg/kg.Acute percutaneous LD50 to rabbits is 8000mg/kg.No adverse impact is found on rats after been feed with caboxin at the dosage of 200ppm/day for nenety days.LC50(8days) to mallard ducks and quail are respectively greater then 4640 mg/kg and 10000 mg/kg.Toxicity to fish:LC50(96h)to rainbow trout is 2.0mg/L.Carboxin decomposes rapidly in soil.Field experiments demonstrate more than 95% of carboxin disappears within two weeks. SPEICIFICATION FOR CYMOXANIL TECHNICAL The active ingredient content(w/w) is greater than 97.0%.The acidity(calculated on H2SO4) is less than 0.2%.The moisture is less than 0.6%.The materials insoluble in acetone is less than 0.5%. PACKAGE SIZE The common package is 25kg/cardboard barrel or 25 kg/knitted bag.We can also make the packages according to customer's requirement. APPLICATION

  Carboxin is a systemic fungicide.Using carboxin to treat seeds of wheat and barley,wheat loose smut and barley real smut can be prevented and cured.Having high effectivity to threadlike nucleus fungi,carboxin is often used as seed treatment of cotton,peanut,vegetable and sugar beet.It also can be used as preservative to lignum.The concentrations lower than 8 ppm can inhibit the growth of basidiomycete's mycelium.In addition,carboxin can control wheat leaf rust,legumina rust,cotton seedling wilt and greensickness.
