Pesticide for controlling pyricularia oryzae

Abstract

The invention discloses a pesticide for controlling pyricularia oryzae. The pesticide comprises kasugamycin and prochloraz in a mass ratio of (1-5):(1-5). According to the invention, after being compounded and mixed, kasugamycin and prochloraz have a synergistic effect, thus solving the problem of drug resistance of drug resistant pyricularia oryzae to single kasugamycin or prochloraz; the use amount of the pesticide can be effectively reduced; the labor intensity is lowered; the cost is saved; the problem of applying excessive pesticides is solved; and the pesticide is simple and practicable and has wide material source, low cost and good using effect.

Description

technical field [0001] The invention relates to the field of agricultural science and technology, in particular to a pesticide for preventing and treating rice blast. Background technique [0002] In recent years, my country's rice planting area has been relatively stable at more than 400 million, accounting for about 30% of the grain crop area, and the output is close to half of the total grain output. Rice blast is one of the three major diseases of rice in my country. This disease occurs in all rice producing areas in my country and can cause a large reduction in yield. Especially the early and severe panicle blast can cause white ears and even extinction. At present, in production practice, a single pesticide is generally used for the control of rice blast. Single-drug control of rice blast, the bacteria are more likely to develop resistance, which will inevitably lead to a multiplied increase in the number of control times and the amount of pesticides used in productio...
