Composite biological insecticide

Abstract

The invention discloses a compound living insecticide, including materials of the following volume portions of 10 to 20 portions of diflubenzuron; 0.01 to 0.1 portion of tryptophan; 1 to 2 portions of dispersant; 2 to 5 portions of glycerin; 72.9 to 86.99 portions of sterile water; the invention also includes clostera anachoreta granulosis virus, Bacillus thuringiensis fungus gemma and ENHANCIN increasing protein. The content of the clostera anachoreta granulosis virus is 0.5 to 2 billion per milliliter; the content of the Bacillus thuringiensis fungus gemma is 2 to 6 billion per milliliter; the content of the ENHANCIN increasing protein is 20 to 50 international units per milliliter. The compound living insecticide has the advantages of reasonable compatibility of medicines, convenient manufacture, broad desinsection spectrum and good desinsection effect. The invention overcomes the defects of wettable powder and emulsion; accessory ingredient is easy to disperse. The invention is more convenient to apply in fields and has no remnant and environment pollution, thus having remarkable superiority in actual application and being suitable for massive application on the forest industry.

Description

technical field [0001] The invention belongs to virus-containing biocide, in particular to a composite biopesticide for poplar Lepidoptera pests. Background technique [0002] In recent years, poplar leaf-eating pests have caused huge economic losses to my country's forestry production. pests. These pests are widely distributed in my country, with overlapping generations, mixed generations, and a large amount of leaf-eating. With the influence of global warming and other factors, the occurrence and damage of poplar Lepidoptera pests have a tendency to increase year by year. In 2005, poplar moth and poplar moth broke out in many places in Henan, Hubei, Hunan and other provinces, causing serious damage to large poplar forests and greatly limiting the development of poplar planting in my country. [0003] The current control of poplar pests mainly relies on chemical pesticides, but the pests multiply rapidly and have multiple generations every year, and chemical pesticides als...
