Problems solved by technology

[0006] At present, the variety of domestic biological seed coating agents is relatively single, and the large-scale production technology is backward. Although many biological pesticide varieties have been developed and registered, the production level of many varieties is low, and the control efficiency is low. The production cannot be optimized and precisely controlled; in post-processing and dosage form development, the control of soybean cyst nematode and soybean root rot, which are soybean root diseases, has not been well done, so as to better promote plant growth

Abstract

The invention provides a biological seed coating agent for controlling a soybean root disease. The biological seed coating agent is prepared from the following components in percentage by mass: 0.02-0.15 percent of CuSO4, 0.05-0.26 percent of (NH4)6Mo7O24.4H2O, 0.01-0.05 percent of H3BO3, 0.1-0.5 percent of MnSO4, 0.04-0.25 percent of FeSO4, 1.5-6 percent of KH2PO4, 0.02-1 percent of K2SO4, 2-8 percent of dispersing agent, 2-5 percent of film-forming agent, 0.1-1.2 percent of warning color, 0.95-2.65 percent of binder and the balance of biocontrol strain fermentation solution. The biological seed coating agent provided by the invention is used for coating soybean seeds, and can achieve the effects of restraining soybean cyst nematode and soybean root rot, so that the soybean root disease is prevented and controlled effectively, soybean plant growth can be promoted, and the yield is increased.

Description

technical field [0001] The invention belongs to the technical field of microbial pesticides, and in particular relates to a biological seed coating agent for controlling soybean cyst nematodes and soybean root rot, a preparation method and application thereof. Background technique [0002] Soybean cyst nematode disease is caused by the infection of soybean cyst nematode (Soybean Cyst Nematode, SCN), and is one of the important diseases that endanger soybean production in the world. It is a soil-borne disease that is extremely difficult to control and often causes serious losses to soybean production. The disease generally reduces the yield of soybean by 10% to 30%, and in severe cases, it can reach 70% to 90%, and even leads to complete production, which is more harmful than any single disease. Currently, the disease has been reported in almost all soybean producing areas. In my country, Heilongjiang, Jilin, Liaoning, Inner Mongolia, Hebei, Henan, Shandong, Shanxi, Shaanxi...
