Nematicidal preparation

Abstract

The invention belongs to the field of pesticides, and particularly relates to a nematicidal preparation containing abamectin and T.longibrachiatum. The preparation is prepared from an abamectin solution and T.longibrachiatum bacteria liquid, so that an effect of toxically killing wheat cereal cyst nematode can be remarkably improved, a slow release effect is achieved, the lasting period of a pesticide can be prolonged, and the preparation is non-pollution and good in environmental compatibility, achieves low production cost, is capable of preventing nematode from easily becoming resistant to drugs, and has the effects of enlarging a prevention and cure spectrum and improving synergistic interaction, and the like.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a nematicide preparation containing abamectin and Trichoderma longibrachiata. Background technique [0002] Wheat cereal cyst nematode (Heterodera avenae) belongs to plant sessile parasitic nematode, and it is a kind of disease that occurs widely in my country and the main wheat producing areas in the world in recent years. Since the nematode was first discovered in the United Kingdom in 1908, the disease has been reported in 32 countries. For example, only in Victoria and South Australia in Australia, the area of ​​wheat damage has reached 200×10 4 hm 2 , leading to a 23% to 50% reduction in grain production, and a 73% to 89% reduction in production in severe cases, and the annual economic loss can reach 70 million US dollars. In the major cereal crop growing areas in Europe, more than 50% of the fields are infested and harmed by the wheat cereal cyst nematode. In my country, wheat ...

Problems solved by technology

[0003] At present, the prevention and control of plant nematode diseases mainly adopts chemical control such as carbofuran, ground line phosphorus, Miller and Haoniandong, etc., and the control effect can reach more than 90%, but it has high soil residue and high toxicity, and harms the soil. In addition, with the increasing awareness of the hazards of chemical agents and the increasing awareness of environmental protection, the use of chemical pesticides has been restricted.
