Problems solved by technology

At present, there are only a few varieties of medicaments for preventing and treating tobacco virus disease in the domestic market, such as Virusbigram, OS Sterling, Junkeduke, Zhibingling, Jingtuling, Disinfecting Lidang, etc., and the effects of preventing and treating tobacco virus disease are not enough. Ideal, due to long-term use has produced certain drug resistance, and most of them are chemical pesticides, high cost of control, polluting the environment, and excessive residues
[0004] There is no better agent for preventing and treating plant virus diseases in foreign literature

Abstract

The invention relates to a biochemical pesticide mixed fatty acid preparation and its application. The mixed fatty acid preparation contains 1-30% mixed fatty acid and 70-99% auxiliary agents based on the total weight of the mixed fatty acid preparation; the auxiliary agents are surfactants, emulsifiers, antifreeze agents, dispersants and the like. The mixed fatty acid preparation of the present invention has an EC50 of 0.0479 mg / L for the tobacco virus disease, has strong lethality against the tobacco virus disease, and the control effect can reach more than 70% 14 days after administration. The mixed fatty acid preparation of the invention has the characteristics of high efficiency, low toxicity, low price and no environmental pollution, and has extremely broad market application prospects.

Description

【Technical field】 [0001] The invention belongs to the technical field of pesticides. More specifically, the present invention relates to a biochemical pesticide mixed fatty acid preparation, and also relates to the use of the mixed fatty acid preparation. 【Background technique】 [0002] Plant virus disease is a kind of worldwide disease, harms various crops such as tobacco, cotton, hemp, vegetable, rice, wheat, peanut, soybean, melon, fruit tree and corn. my country is a large agricultural country, and the economic losses caused by plant infection by viral diseases amount to billions of yuan. With the impact of global climate change, the occurrence of plant virus diseases is becoming more and more serious, which seriously threatens the agricultural production of our country. [0003] At present, Chinese researchers have carried out a lot of research work on plant virus diseases, and have made remarkable progress. For example, CN102047883A discloses an anti-plant virus dis...
