Insecticidal composition containing Empedobacter brevis and monosultap

Abstract

The invention discloses an insecticidal composition containing Empedobacter brevis and monosultap. The composition contains Empedobacter brevis and monosultap, wherein a weight ratio of Empedobacter brevis to monosultap is 1:60 to 60:1. The insecticidal composition has the advantages of good insecticidal fast action effect, long persistent period, low toxicity, low residual, no pollution, good safety to environment, improvement of the insecticidal effect, safety increase, and reduction of environment pollution.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to an insecticidal composition of Stenobacter brevis and monosultap. 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 i...
