Abstract

The invention provides a film spreading oiling agent used for preventing and controlling plant diseases and insect pests at a basal part of a rice stem and an application. The film spreading oiling agent comprises insecticidal and sterilization active ingredients and an additive. When the preparation is used, the film spreading oiling agent can be directly poured into a paddy field without dilution by using water. After entering the water, the film spreading oiling agent is distributed and spread as an oil film to spread all over the rice field and climb along a rice straw, and can effectively prevent and control rice stem borer and banded sclerotial blight, thus being a novel pesticide formulation with high working efficiency.

Description

technical field [0001] The invention relates to a film-spreading oil agent for diseases and insect pests at the base of rice stems and its application, belonging to the technical field of pesticide preparations. Background technique [0002] The occurrence of diseases and insect pests at the base of rice stems accompanies the whole growth process of crops, among which the most serious stem borer and rice sheath blight occur in rice fields almost every year. Chilo borer is one of the most serious frequent pests of rice in my country. It is damaged at the tillering stage and causes withered sheaths and dead seedlings. It is damaged at the ear stage and causes insect damage to plants and white ears. In general, the annual yield is reduced by 3% to 5%. , in severe cases, the production reduction is more than 30%. Rice sheath blight is one of the most common major diseases of rice. Generally, early rice is heavier than late rice, which often causes the grains to be not full, and ...
