Biopesticide without pesticide residue

Abstract

The invention discloses a biopesticide without pesticide residue; the biopesticide comprises the materials in parts by weight: 35-46 parts of alternaria tenuis nees, 20-40 parts of jasmine oil, 12-18 parts of rice hull powder, 21-26 parts of amino acid, 5-12 parts of allicin, 5.5-7 parts of magnesium phosphate, 5-8 parts of anise, 35-46 parts of corn straws, 10-16 parts of verticicladiella powder, 5-19 parts of amino-oligosaccharin, 25-40 parts of erythrina indica sawdust and 80-100 parts of water. The biopesticide has no pollution to the environment, safe to humans and domestic animals and low in price, has no pesticide residue and is a nuisanceless biopesticide.

Description

technical field [0001] The invention relates to a biological pesticide without pesticide residue. Background technique [0002] Powdery mildew is an important plant disease that can infect a variety of crops such as barley, wheat, watermelon, cucumber, cucumber, zucchini, eggplant, pepper, grass lane, strawberry, rose, rose, rubber tree and some Chinese medicinal materials, etc., and cause serious losses . Powdery mildew is a multi-cycle obligate parasitic disease with a short incubation period, multiple generations can be reproduced in one growing season, and the reproduction rate is high. Under suitable climatic and environmental conditions, it may occur on a large scale and spread rapidly. According to statistics, the annual loss caused by powdery mildew in the world reaches 586.3 billion US dollars. [0003] At present, due to the complexity of the pathogen itself and the difficulty of accurately identifying the pathogen, the types of powdery mildew may be different i...
