Insecticidal composition containing Stenobacter brevis and dimehypo

Abstract

The invention discloses a pesticidal composition containing empedobacter brevis and bisultap. The pesticidal composition includes the empedobacter brevis and the bisultap as active components, wherein the weight ratio of the empedobacter brevis to the bisultap is 1:60-60:1. The pesticidal composition has quick effects and long lasting period, is free of residue and pollution, is safe to environment, is improved in pesticidal effects due to the form of composite preparation, is improved in safety and reduces environment pollution.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to an insecticidal composition of Stenobacter brevis and dimehypo. Background technique [0002] The rice leaf roller (Cnaphalocrocis medinalis Guenee) is one of the main pests in rice producing areas in my country, and it is widely distributed in various rice areas. It damages rice with larvae, which form vertical bracts and hide in them to feed on the upper epidermis and mesophyll, leaving only the white lower epidermis. The damage at the seedling stage affects the normal growth of rice, or even dies; the damage from the tillering stage to the jointing stage, the tillering is reduced, the plant is shortened, and the growth period is delayed; after the booting period, especially the damage to the flag leaves from the heading to the full heading stage, the flowering and fruiting are affected, and the empty shell rate is increased. Thousand-grain weight decreased. Generally, the yield is ...
