The Manufacture Of Two New Type Pesticides For Seed Coatinng

The technique of seed coating and seed dressing agents, marked with its high contents of science and technology and economic benefits, is an advanced comprehensive technique which will sure give an impetus to a healthy growth of the seeding industry. While flowable water concentrate for seed treatment keeps the major share of the domestic market, seed dressing agents in solid state are rare. Compared with flowable water concentrate for seed treatment, solid agents for seed treatment bear the characters of high contents, high stability in physic-chemical qualities as well as small bulk, hence possessing the advantages of easy storage and convenient shipping.Based on the study and production of water dispersible granules (tablets) and wettable powder, the author of the following thesis has done a lot of research work and developed two new kinds of solid agents of seed treatment. This thesis paper will deal with the technology of the author's new research achievement, such as imidacloprid, myclobutanil, tebuconazole, and abamectin . Lots of researching experiments have let to a stable formula and trial production. Its lab and field experiments of efficacy show that the given solid agents for seed treatments are stable of good effects in resistance to insect pests and diseases, drought and floods, while they are effective in speeding the growth of the plants and crops.This dissertation with its thorough research on lab and field work and its two new kinds of seed dressing agents as its direct achievements probes the prosperity of solid agents for seed treatment, which sure bears great significance in promoting the development of our agriculture.
