Problems solved by technology

Due to the long growth cycle of strawberries, creeping growth, serious pest damage, and unsatisfactory control effects of pesticides, since strawberries are berries, the fruits are eaten fresh, and it is inconvenient to clean them thoroughly. Pesticide residues in fresh strawberries have always been a concern

Abstract

The invention relates to plant-source biopesticide for preventing strawberry diseases. The biopesticide is prepared from 10-60wt% of cinnamyl aldehyde and Szechwan chinaberry fruit extracts as well as allicin and capsaicine, 8-10wt% of surfactant, 8-10wt% of pythium oligandrum, 0.01-0.5wt% of chitosan, 10-50%wt% of synergist and the balance being 95% ethyl alcohol and turpentine as well as lavender essential oil, palchouli oil and perilla oil. The biopesticide takes the cinnamyl aldehyde and cinnamyl aldehyde extracts as main active ingredients, thereby having no toxicity and harm and good volatility and overcoming the defects that pesticide residue is increased and ecological environment is destroyed. Besides, even though the biopesticide is higher than chemical pesticide in cost at present, the biopesticide has many advantages on a long view due to good social benefit and less environmental pollution.

Description

technical field [0001] The invention relates to a botanical biopesticide for preventing and treating strawberry diseases, belonging to the field of biological control of strawberry diseases. Background technique [0002] According to the field investigation and identification, the main strawberry diseases and insect pests include powdery mildew, root rot, anthracnose, gray mold, leaf spot, spider mite, two-spotted spider mite, flower thrips, aphids, etc. Among them: powdery mildew, root rot, spider mite, two-spotted spider mite, and flower thistle are the most serious damage. The rate of powdery mildew disease is close to 100%, the rate of diseased plants often reaches more than 60%, and the production loss is 10% to 30%. The general incidence of rot is 5% to 15%, and in severe cases, it can reach more than 50% or even completely destroy; red spider mite, two-spotted spider mite, and flower thrips are common, and the loss is estimated to be 10% to 20%.
