Abstract

The invention relates to a rice blast prevention and control insecticide, which consists of the following effective components in parts by weight: 0.1 to 55.0 parts of kasugamycin and 0.1 to 25.0 parts of glucan. According to the rice blast prevention and control insecticide, the synergistic effects of sterilization activity of kasugamycin and resistance induction of glucan are used for preventing and controlling the occurrence and development of rice blast, the insecticide has both prevention and control effects, and remarkable prevention and control effects can be achieved whenever the insecticide is used before or after the occurrence of the rice blast.

Description

technical field [0001] The invention relates to a control agent for rice blast. Background technique [0002] Rice blast, also known as rice fever, is one of the three most serious diseases that harm rice. It can cause a substantial reduction in rice production, in severe cases, by 40%-50%, or even grain failure. Rice blast occurs all over the country, mostly on leaves and nodes, and the main types are seedling blast, leaf blast, node blast, panicle blast and grain pox. [0003] The rice blast fungus survives the winter on diseased valleys and grass with conidia and mycelium, and germinates to produce conidia under suitable climatic conditions, and spreads by airflow, which is a multi-cycle disease. The comprehensive control method adopts a comprehensive control strategy based on the elimination of overwintering bacteria sources, selection of disease-resistant varieties as the center, fitness cultivation as the basis, and chemical control as the auxiliary. Usually, the focu...
