Compound pesticide for protecting and curing rice sheath blight

Abstract

The invention relates to a compound pesticide for protecting and curing rice sheath blight, which belongs to the technical field of compound pesticides. The compound pesticide is characterized by containing 0.15-25 percent of thifluzamide and 1-50 percent of validamycin. The compound pesticide for protecting and curing the rice sheath blight is prepared by compounding the thifluzamide and the validamycin and has good protecting and curing effect; and field trials shows that the protecting and curing rate of the compound pesticide can reach 98 percent. The compound pesticide has strong persistence and prolongs the period of validity of protecting and curing the rice sheath blight to be 30 days; and the production cost of the compound pesticide is lower and is reduced by more than 50 percentcompared with a pesticide which singly uses the thifluzamide.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, in particular to a compound pesticide for preventing and treating rice sheath blight. Background technique [0002] Rice sheath blight is a common and frequently-occurring disease of rice in my country. The common ones are Jinggangmycin, etc. Jinggangmycin, also known as effective mycin, is a low-toxic fungicide. The acute oral LD50 of pure rats and mice is greater than 2000 mg / kg, and the LD50 of subcutaneous injection is greater than 1500 mg / kg. 5000 mg / kg applied to the skin of rats has no toxic reaction. Low toxicity to fish, carp TLM (96h) LD50> 40 mg / L. Dosage forms include 5%, 10% water and 5%, 20%, 28% water-soluble powder. It is an antibiotic produced by actinomycetes. It has strong systemic properties, is easily absorbed by bacterial cells and rapidly conducts in it, interfering with and inhibiting the growth and development of bacterial cells. It is mainly used for ...
