Complex insecticidal bactericide used for controlling paddy rice insect disease

Abstract

The invention discloses a complex insecticidal bactericide used for controlling paddy rice insect diseases. The effective components of the insecticidal bactericide are avermectin and / or emamectin benzoate (with a chemical name of (4''-r-4''-deoxy-4''-methylamino avermectin benzoate, emamectin benzoate for short), azoxystrobin (with a chemical name of (E)-2-{2-[6-(2-cyanophenoxy]pyrimidin-4-yloxy}phenyl)-3-methoxyacrylate), and validamycin. The complex insecticidal bactericide has a function of controlling both pests and diseases. With the insecticidal bactericide, rice sheath blight, false smut and rice leaf roller or borer can be simultaneously controlled. The pests comprise pink borer, stem borer, three borer, and the like. With the insecticidal bactericide, pesticide dose in the field can be reduced, pesticide can be saved, labor can be saved, agricultural cost can be reduced, and pest and disease controlling quality can be improved.

Description

technical field [0001] The invention relates to a compound insecticide and fungicide for preventing and controlling rice diseases and insect pests, and belongs to the field of pesticides. Background technique [0002] In recent years, the rice leaf roller has been rampant in southern my country and the Yangtze River Basin, causing significant losses in rice yield. Due to the complexity and diversification of rice planting methods and systems, with the promotion of high-yield varieties and the increase of nitrogen application levels, the incidence of rice sheath blight also tends to aggravate, and diseases and insect pests often occur at the same time, resulting in many varieties, specifications and doses of drugs used in production. Too many and frequent use make the left-behind farmers with low education levels buy several kinds of medicines at a time, and temporarily add them to the fields, which increases the difficulty of rational use of medicines, which not only serious...

Problems solved by technology

Due to the complexity and diversification of rice planting methods and systems, with the promotion of high-yield varieties and the increase of nitrogen application levels, the incidence of rice sheath blight also tends to aggravate, and diseases and insect pests often occur at the same time, resulting in many varieties, specifications and doses of drugs used in production. Too many and many times, so that the left-behind farmers with low education levels buy several kinds of medicines at a time, and temporarily add them to the fields, which increases the difficulty of rational use of medicines, which not only seriously affects the quality of prevention and control, but also causes waste and environmental pollution.
