Fenoxycarb and nitenpyram compound pesticide

Abstract

Fenoxycarb and nitenpyram compound pesticide belongs to the technical field of compound pesticides and is characterized in that the fenoxycarb and nitenpyram compound pesticide contains the substances in percentage by weight as follows: 3.5-4.5% of fenoxycarb and 1.5-2.5% of nitenpyram. The cotoxicity coefficient of the compound pesticide to cnaphalocrocis medinalis is more than 120; and the compound pesticide has better synergy and has better control effect to nilaparvata lugens, cnaphalocrocis medinalis and other lepidoptera and homoptera pests. The compound pesticide has the advantages of low toxicity, wider insecticidal spectrum, good quick-acting and lasting effects, and low manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, in particular to compound pesticides of fenoxycarb and nitenpyram. 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. Pesticides used to control major rice pests, such as rice leaf rollers, have used monosultap and chlorpyrifos for many years. In the past 3 to 5 ye...
