polymer coating method of apple diseases and pests control method of.

摘要

this invention is a polymer of a coating method using the plant diseases and insect pests of apple wants to live, and the amount of the pesticide can be reduced, and as a method of disease and pest control in apple yuan about. the characteristics of apple branches formed in the same layer of the pattern etching of the ovary and the formation of bacteria or the like of the aphid pests, such as part of high molecular material with plastic, and to prevent the spread of disease, and the proliferation of loyalty, to destroy the disease in addition to pests method.;used polymer material is polyvinyl alcohol, polyvinyl acetate, starch containing plastics, resin, photolysis of resin and synthetic high molecular material, the process of the lactone and the exchange resin, poly ethylene glycol, local group policy for the uc5d0uc2a4, not like the synthesis and decomposition. the base material, the blue, dextran, the collar so that the alginate, the scattering of the sword, the world record of silicon aluminum strip the old xian yue and microbial production raw material of polymer material, starch and modified starch, cellulose and its derivatives, chitosan, a natural key soil and water the origin of the raw material. the material and the polymer material, alone or mixed with water or alcohol in the apple tree, toxic solvent or heat treatment, melt spray or apply for use.;this invention is in 16 ~ 20 times, the need of an application of the fungicide may be members of the class to reduce the residue of pesticides, to alleviate the problem of resources, reduce and quality improvement effect can be expected. in particular, the application of pesticide and pesticide to the labor saving, and plant diseases and insect pests of apple yield and to reduce the production of sikkim as i can, and the uruguay round, in order to prevent the production of an international uacbduc7c1ub825 can improve.
