Abstract
The invention discloses an insecticidal composition containing beauveria bassiana and diflubenzuron. The insecticidal composition is prepared from an effective component composed of beauveria bassianaand diflubenzuron, and an appropriate amount of an agricultural insecticide auxiliary agent is added. According to a preparation method, reasonable utilization of low dosage chemical pesticide diflubenzuron and beauveria bassiana spore germination promoter strigolactone is capable of improving the rapid effect and comprehensive prevention and treatment effect of beauveria bassiana on crop pests greatly, reducing using of chemical pesticides, reducing ecological destroy and environment pollution, and increasing crop yield and quality.
Description
technical field [0001] The invention belongs to the field of agricultural insecticides, in particular to an insecticidal composition of Beauveria bassiana and diflubenzuron. Background technique [0002] Since the 1990s, with the increasing requirements of human beings on the environment and the quality and safety of agricultural products, pesticides must be developed in the direction of low toxicity and pollution-free, and biopesticides are a kind of products that meet the above requirements and are compatible with the environment. Green pesticides. Beauveria bassiana is an ascomycete entomogenic fungus, which can invade 6 orders, 15 families, more than 200 kinds of insects and mites and reproduce in large numbers, and at the same time produce beauveria (non-ribosomal polypeptide toxoid), Osporin (benzoquinone toxoid) and calcium oxalate crystallize, causing insect poisoning, disrupting metabolism and causing death. The distribution range of Beauveria bassiana is very wid...
