Abstract

The invention discloses a nitenpyram and quintiofos compound pesticide and belongs to the technical field of compound pesticides. The nitenpyram and quintiofos compound pesticide is characterized by comprising the following substances in percentage by weight: 1.5 to 2.5 percent of nitenpyram, and 11 to 13 percent of quintiofos. The cotoxicity coefficient of the nitenpyram and quintiofos compound pesticide on rice brown planthoppers is over 120; by compounding the nitenpyram and the quintiofos, the pesticide has a remarkable synergistic effect; and the pesticide has a good effect of controlling Lepidoptera pests and Homoptera pests of rice. The compound pesticide is low in toxicity and high in quick action and persistence, and has a relatively broad insecticidal spectrum.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, in particular to the compound pesticides of nitenpyram and quinathion. 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...
