Embodiment 1

[0019] Dilute the 5% chitosan oligosaccharide solution with water to the corresponding application concentration, the concentration is calculated according to the weight percentage concentration, and is calculated in ppm (parts per million) concentration in the result record, and 50ppm represents the weight percentage in the result record below The concentration is 0.005%. Water treatment was used as a control. The diluted solution is used to treat various diseased crops and crops that have been treated with pesticides in stages according to requirements, and the interval of spraying treatment is 15 days. Each treatment was observed and detected in 3 experimental fields (100 square meters of crops or 20 fruit trees), and the corresponding pesticide residues in the crops in the crops harvested in each experimental field were detected and counted. The timing of applying the chitosan oligosaccharide solution to treat crops is 5 days after the application of pesticides for preven...

Abstract

The invention which relates to a chitosan oligosaccharide composition for reducing the content of residual pesticides in crops, a purpose thereof and a method thereof concretely provides a pesticide composition for reducing the content of the residual pesticides in the crops. The pesticide composition comprises 0.003-0.008 wt% of a chitosan oligosaccharide. The invention also provides a purpose of the chitosan oligosaccharide-contained pesticide composition in reducing the content of the residual pesticides in the crops and a method for applying the chitosan oligosaccharide-contained composition in reducing the content of the residual pesticides in the crops. According to the invention, an important problem of the reduction of the content of the residual pesticide in the crops is solved; and after the chitosan oligosaccharide-contained pesticide composition is adopted to process the pesticide applied crops, the content of the residual pesticides in the crops is reduced, the phytotoxicity to the crops is not generated, and no secondary pesticide residual problems appear.

Description

technical field [0001] The invention belongs to the field of agricultural chemistry, and in particular relates to a whitefly control composition and control method, in particular to a chitosan oligosaccharide composition for reducing pesticide residues in crops and its application and method. Background technique [0002] At present, in agricultural and horticultural production, it is inevitable to use various pesticides for the prevention and treatment of crops, vegetables, fruits and cultivated herbal medicines, which not only causes serious pollution to the environment, but also makes the pesticide residues in the products exceed the standard, which seriously affects people. The health of the country and the export of agricultural products. [0003] The present invention finds that chitosan oligosaccharides can effectively reduce residues in crops applied with pesticides, which is a crucial discovery for video security and the like. Contents of the invention [0004] I...
