Product description：

Carbendazim is a widely used, systemic, broad-spectrum benzimidazole fungicide and a metabolite of benomyl. It is also employed as a casting worm control agent in amenity turf situations such as golf greens, tennis courts etc. and in some countries is licensed for that use only.

Physical and chemical properties:

The pure product is white crystals, the melting point is 302～307℃ (decomposition), the density d420 is about 1.45, and the vapor pressure is 0.09mPa at 20℃. At 24°C, the solubility in water is 29mg/L when pH=4, 8mg/L when pH=7, and 7mg/L when pH=8. Solubility in organic solvents: 300mg/L in ethanol, 5g/L dimethylformamide, 36mg/L in benzene, 300mg/L in acetone, 100mg/L in chloroform, 68mg/ChemicalbookL in dichloromethane. Stability: Decomposes at the melting point temperature. It can be stored for at least two years under 50℃, and stable for 7 days under 20000lux light; hydrolysis (22℃) DT50>350 days (pH5 and pH7), 124 days (pH9), in acid It forms salt in the soil, and the DT50 is about 1 to 5 months in the soil. It is soluble in dilute inorganic acid and organic acid to form corresponding salt. Slowly decompose in alkaline solution. The original powder is light gray powder, stored in a cool and dry place for two years, the content of active ingredients is basically unchanged, and it is relatively stable to heat.

Usage：

High-efficiency, low-toxicity, broad-spectrum, systemic fungicide, with a long duration, effective against many ascomycetes, imperfect bacteria and various basidiomycetes, but ineffective against algae and fungi. Used to control wheat head blight, rice sheath blight, rice blast, sclerotinia sclerotiorum, many fruit tree and vegetable diseases, such as Chemicalbook powdery mildew, anthracnose, scab, etc., use 50% wettable powder 750～1000 Times liquid spray.
