Problems solved by technology

However, as a microbial insecticide, Bacillus thuringiensis also has some natural defects: its selectivity is strong, and its insecticidal spectrum is narrow; It can only be attached to the surface of crops, and is greatly affected by natural environments such as rain and temperature. These all limit its virulence, making it unable to compete with chemical pesticides, and its sales volume only accounts for the world's insecticides. percent of the total dose

Abstract

The biochemical composite pesticide is prepared through re-compounding biological pesticide bacillus thuringiensis and chemical pesticide fipronil and adding proper amount of assistant and carrier. The weight ratio between parasporal crystal protein as the effective component of bacillus thuringiensis and fipronil is 0.066-10. The bichemical composite pesticide has a co-toxicity coefficient to rice stem borer and cabbage moth as high as 275 and 156 separately. The obvious synergistic effect makes the composite pesticide capable of killing rice stem borer, cabbage moth and other pests fast and effectively with wide pesticidal spectrum, low toxicity, low residue and low cost.

Description

technical field [0001] The invention relates to an insecticide for controlling rice and vegetable pests such as rice borer, rice borer, rice borer, diamondback moth, etc., in particular to a biochemical composite insecticide. Background technique [0002] Rice is the main grain crop in my country, and it is planted in most provinces and regions of the country. Its planting area is nearly 407 million mu, accounting for about 30% of the grain planting area, and its annual output accounts for about 40% of the annual grain grain output, ranking first in the world. first place. However, the harm of various rice pests has seriously affected the production of rice. According to statistics, the annual loss caused by disease and insect pests accounts for about 10% to 15% of its total output, especially the damage of rice stem borer, rice stem borer, and rice stem borer. The hazards are particularly serious. Chilo borer is distributed in most of the rice areas in ...
