Composition containing agritol for rice stem borer prevention and control

Abstract

The invention relates to an insecticidal composition containing Bacillus thuringiensis for controlling rice borer, which is composed of Bacillus thuringiensis, monosultap, a synergist and a carrier. By weight of insecticide, Bacillus thuringiensis accounts for 40-70%, monosultap accounts for 20-50%, and synergist accounts for 2-8%. The invention has a good control effect on rice stem borer, rice stem borer and other borers, up to 94.82%, and has a good prospect of popularization and application.

Description

technical field [0001] The invention relates to an insecticide composition, in particular to an insecticide composition containing Bacillus thuringiensis for controlling rice borer. Background technique [0002] Bacillus thuringiensis preparations (i.e., B.t preparations) are representative of microbial insecticides, which can control various kinds of insecticides such as cabbage caterpillar, diamondback moth, rice budworm, rice leaf roller, sweet potato hornworm, tobacco budworm, cotton bollworm, lamp moth, etc. pests. It has the advantages of wide application, no residue, no pollution to the environment, and is safe for humans, animals, and natural enemies. However, the activity and stability of the agent are greatly affected by the environment; insects must be swallowed to enter the body of the insect to kill insects, and it is difficult to kill insects. The pests in the plant body and roots can only have a good use effect at a certain stage of insect development; pest...

Problems solved by technology

However, the yield of rice is seriously threatened by diseases and insect pests. Among them, stem borers are common and serious damage. The stem borers mainly include rice stem borers, stem borers, and rice stem borers. White spikes and cores, and large borers cause rice cores, resulting in reduced rice yields, and severe yield loss
