Problems solved by technology

High-quality mineral oil emulsion has a place in the high-end pesticide market due to its high level of processing technology, good and stable efficacy against pests, and little damage to crops. However, because it is a non-renewable raw material, its cost is high and its application is limited.
And present biological source oil, although source is extensive (as gutter oil, vegetable oil, animal oil etc.), its composition is complicated, and drug effect is unstable, and there are too many harmful components in oil, and the phytotoxicity to crop is difficult to solve, and fine The processing cost is high, so it is difficult to promote the application in a large area
[0003] Soy sauce is a traditional condiment in my country, with a huge production volume, and soy sauce residue is a waste produced by the fermentation and brewing of soy sauce. It has a large amount of water and is prone to mold and odor, and is difficult to preserve. Improper treatment will cause environmental pollution.

Abstract

The invention discloses application of a soy sauce residue glyceride in preparation of a preparation for controlling minisize insects or foliar fungal and bacterial diseases. The soy sauce residue glyceride is a glyceride containing C16-C22 fatty acids. According to the invention, the soy sauce residue glyceride is taken as a main component, and effective auxiliary agents are added for preparationof a pesticide preparation. Through tests, the pesticide preparation has a same controlling effect on tetranychus urticae, diaphorina citri, panonychus citri, aedes albopictus and other minisize insects and sooty mould and other diseases compared with a current mineral oil emulsion, and does not show phytotoxicity after repeated application to crops for a short period of time. The pesticide preparation has the advantages of simple and stable ingredients, high safety, good anti-insect and disease-preventing effects, and no phytotoxicity to crops. The main components and additives of the pesticide preparation are food grade, and easy to degrade in environment, and the pesticide preparation is easy for industrialized standardized production, and has strong market competitiveness compared with mineral oil emulsions.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to the application of soy sauce residue glyceride in the preparation of preparations for preventing and controlling micro-pests or foliar fungal and bacterial diseases. Background technique [0002] Environmentally friendly oil-based pesticides have a physical control effect, and the resistance of diseases and insect pests to them is low, so they have good application prospects. However, in order to truly have the ability to compete in the market, pesticides are required to have good and stable efficacy, no harm to crops, simple use and low cost. High-quality mineral oil emulsion has a place in the high-end pesticide market due to its high level of processing technology, good and stable efficacy against pests, and little damage to crops. However, because it is a non-renewable raw material, its cost is high and its application is limited. . And present biological source oil, alt...
