Abstract
The invention discloses a virus disinsection suspending agent, comprising the azadirachtin, wherein; the main component of the preparation formulation is azadirachtin the, content of which is 0.1% to 10wt%; the virus is a virus or a plurality of viruses of nuclear polyhedrosis virus (NPV); the virus inclusion body content in the suspending agent is 0.5 billion to 20 billion PIB / ml. The invention has the advantages of no harm to human, livestock and other higher animals, no environmental pollution, no pesticide residue, effective control on the occurrence and the damage of the agricultural and forestry pests, stable performance and increased disinsection speed of the products due to the antifreeze, the stabilizing agent, the sun-screening agent, the potentiating agent, the dispersing agent, the defoamer, the pH regulator and other addition agents which are added in the preparation, obvious improvement in disinsection speed and disinsection effect of the virus pesticide.
Description
Technical field [0001] The present invention relates to the technical field of pesticides. Specifically, the present invention relates to a virus insecticide suspension containing azadirachtin, which is suitable for biological control of diamondback moth, cotton bollworm, beet armyworm, Spodoptera litura, looper, pine caterpillar, Tea caterpillars, gypsy moths and other resistant pests. Background technique [0002] Because people use single-form chemical pesticides for a long time, pests are prone to resistance. In order to achieve pest control effects, they have to use more toxic pesticides or increase the amount of pesticides. This will not only increase the economic burden of farmers and pollute the ecological environment. , Destroy the ecological balance, affect the safety of agricultural products, and a large number of natural enemies of pests have been killed, resulting in more rampant pests. At present, there are a large number of mixed insecticides on the market, most of...
