Abstract

The invention relates to a nitenpyram and indoxacarb compound agricultural pesticide, which belongs to the technical field of compound agricultural pesticides and comprises the following substances in percentage by weight: 1.5-2.5% of nitenpyram and 1.5-2.5% of indoxacarb. The co-toxicity coefficient of the compound agricultural pesticide to paddy nilaparvata lugens is greater than 120 and has anobvious synergistic effect due to the compounding of the nitenpyram and indoxacarb and has preferable control efficiency on homoptera and lepidoptera injurious insects such as paddy nilaparvata lugens. The compound agricultural pesticide has the advantages of low toxicity, wider insecticidal spectrum, good quick action and persistence and low production cost.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, in particular to the compound pesticides of nitenpyram and indoxacarb. Background technique [0002] Rice is the main variety of food crops in my country, with a large planting area, many types of diseases, insects, and weeds, and the damage is serious. According to the statistics of the agricultural department, due to diseases, insects, weeds and other hazards, the output loss reaches 20-30% every year. The amount of pesticides used to control rice diseases, insects, and weeds accounts for about 50% of the annual pesticide use in my country. The area under the treatment of rice pests in the country is about 1.2 billion mu per year, and the area under the treatment of rice pests will be even larger in the year of large-scale pest occurrence. [0003] Pesticide varieties for the control of major rice pests, such as the control of rice leaf rollers. For many years, monosultap and chlo...
