Problems solved by technology

[0005] The control of Spodoptera frugiperda is still dominated by spraying. Farmers often delay the best spraying time due to various reasons or weather reasons such as rain, resulting in irreparable losses.
The patent "A Pesticide Granule for Controlling Fall Armyworm" (application number: 201910644051.0) and the patent "A Method of Using Seed Treatment to Control Fall Armyworm" (application number: 201910727740.8) carried out seed dressing and seed treatment However, the agents for seed dressing and seed treatment need to have better systemic properties, and the effect is poor when the weather is dry and in the late stage of crop growth
The product in the patent "A Pesticide Composition and Using Method for Controlling Spodoptera frugiperda" (Application No.: 201911101897.6) can be mixed with fine soil and then sprinkled, but soil mixing is not only cumbersome but often causes phytotoxicity and The control effect is not good, and the product of the present invention found in the field test that the heart-throwing treatment can reduce the amount of active ingredients of pesticides by more than 50% compared with conventional spraying treatment, and adopt "a kind of chemical composition and use method for preventing and treating Spodoptera frugiperda" The produced product may be mixed with a large amount of soil due to the low concentration, or due to the large soil adsorption area, a large amount of pesticides are adsorbed by the soil, resulting in low pesticide utilization

Abstract

The invention discloses a lufenuron-containing and emamectin benzoate-containing controlled release granule applied to corn core leaves and used for preventing and controlling spodoptera frugiperda. The granule is prepared from lufenuron, emamectin benzoate, a carrier and a sustained and controlled release component. During production, lufenuron is processed into powder to be wrapped on the surfaces of carrier particles, the surfaces of the particles are wrapped with a sustained and controlled release layer, emamectin benzoate is processed into powder to be wrapped with a layer, and finally the particles are wrapped with a sustained and controlled release layer. The granule can be directly applied to corn core leaves to prevent and control harm of one-season corn grassland spodoptera exigua.

Description

technical field [0001] The invention relates to the field of pesticides in agricultural production, and relates to a slow and controlled release granule for preventing Spodoptera frugiperda, which can be used once and worry-free for one season. Background technique [0002] Fall armyworm, also known as fall armyworm, fall armyworm, fall armyworm, and pseudo armyworm, is a moth belonging to the genus Noctuidae. Since Fall Armyworm entered Yunnan Province, China at the beginning of 2019, it has become a major pest that harms corn and other crops in my country. The occurrence areas of Fall Armyworm are mainly concentrated in the Huanghuaihai and south areas; Southwest and South China have many generations, and Jiangnan Moderate occurrence in the middle and lower reaches of the Yangtze River, light occurrence in the Jianghuai, Huanghuai, Northwest, and North China regions. In 2021, it is estimated that the infestation area will reach 40 million mu. In my country's "Regulations o...
