The specific disease prevention and control are as follows:
Wheat smut, snow rot, snow mold, sheath blight, root rot, total rot, glume blight, stalk smut. Toxicity: Rat acute oral LD50>5000mg/kg, rat acute skin LD50>2000mg/kg, rat acute inhalation LC50>5000mg/L. No irritation to rabbit eyes and skin. The Ames test shows that it is not teratogenic, non-mutagenic, and non-carcinogenic. For wild ducks and quails, LD50>2000mg/kg, LC50>5200mg/L.

Chemical properties;
The pure product is colorless crystal, m.p.199.8ºC, relative density 1.54(20ºC), vapor pressure 3.9×10-7Pa(20ºC), distribution coefficient 4.12(25ºC). Solubility at 25°C: acetone 190mg/L, methanol 44mg/L, n-octanol 20mg/L, toluene 2.7mg/L, hexane 0.0078mg/L, water 1.8mg/L. No hydrolysis occurs under the condition of pH 5-9. A novel, broad-spectrum, non-systemic pyrrole fungicide, by inhibiting the related transfer of glucose phosphorylation and inhibiting the growth of fungal mycelium, and ultimately leading to the death of pathogenic bacteria.
Application:
Foliar treatment of wheat, barley, corn, peas, rape, rice, vegetables, grapes, lawns, and ornamental crops to prevent and control Fusarium nivalis, Tilletia cylindracea, Rhizoctonia solani, etc., with special effects on gray mold; For grain and non-grain seed treatment, control seed-borne and soil-borne pathogens, such as Alternaria, Aspergillus, Aspergillus, Fusarium, Helminthosporium, Rhizoctonia and Penicillium. The recommended dosage is 250~500g active ingredient/hm2. It is safe and non-phytotoxic to the next crop.
