Rice seed dressing agent composition used for preventing and treating black-streaked dwarf disease and its preparation method

Abstract

The invention relates to a rice seed dressing agent composition used for preventing and treating black-streaked dwarf disease and its preparation method. The composition is prepared from effective components, a microelement fertilizer regulator, a solvent, a carrier, a surfactant, and other additives, and can be prepared into suspending agents, water dispersible granules or wettable powder. The effective components include an insecticide and an antiviral agent. The composition can improve seed germination rate, ensure whole, strong and neat seedlings, and can promote growth and development of the seedlings and increase crop yield. The rice seeds that undergo seed dressing treatment can substantially improve the autoimmune system of crops, and can consciously resist disease attack. When effected by the agent, pests can take migratory flight or stop causing harm. The rice seed dressing agent composition of the invention especially have obvious antifeeding and repelling effects on Sogatella furcifera, Nilaparvata lugens, Oulema oryzae, Stenchaetothrips biformis, naranga aenescens moore and other pests of rice, reduce harm and virus spread, decrease or alleviate the occurrence of rice black-streaked dwarf disease, thus having very obvious social and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide seed dressing composition. Background technique [0002] Food security for the world. "The core of food security is rations, and the focus of ration supply is rice. To ensure that my country's grain self-sufficiency rate is above 95%, the self-sufficiency rate of rations such as rice and wheat must be guaranteed to be 100%." However, the rice production process is often affected by natural disasters and harmful organisms. In recent years, black-streaked dwarf disease, which broke out in southern my country, seriously threatens rice production. "Rice black-streaked dwarf disease is a vicious viral disease transmitted by the migratory pest White-backed Planthopper. The degree of coincidence of the infection period is high, and the rice cropping system is complex and suitable for epidemic occurrence. The occurrence of the disease is extremely severe in the double-cro...

Problems solved by technology

Therefore, "the seed coating agent market", one of the hot spots in the rice insecticide market, is an important topic for pesticide researchers. So far, there has been no report on the effective control of rice black-streaked dwarf in the pesticide market.
