Efficient compound pesticide composition containing chromafenozide

Abstract

The invention discloses an efficient compound pesticide composition containing chromafenozide and belongs to the technical field of pest chemical prevention and control. The efficient compound pesticide composition comprises a first active component which is chromafenozide and a second active component which is cycloxaprid. Compared with a single agent, the composition has an obvious synergism for rice leaf folder and other lepidoptera pests and can remarkably improve the prevention and control effect; the composition can replace high-toxicity pesticide, the usage quantity of the composition is reduced, and ecological environment pollution and pesticide residues in rice are effectively reduced; the composition has the obvious synergism for the rice leaf folder and other lepidoptera pests and meanwhile has a good prevention and treatment effect on rice planthoppers and other homoptera pests. In this way, compared with the single agent, the composition can treat multiple pests and obviously reduce the prevention and control cost of the pests.

Description

technical field [0001] The invention belongs to the technical field of pest chemical control, in particular to an insecticide compound composition having a synergistic effect on rice leaf rollers. Background technique [0002] Rice leaf roller is the main pest of rice, which is widely distributed in the rice areas of the country, especially in the southern rice areas, where the density is high and the damage is serious. It mainly damages rice, followed by wheat, millet and sugarcane, and also parasitizes on a variety of gramineous weeds. The larvae roll the rice leaves longitudinally to form buds, and are willing to eat the mesophyll, leaving only a layer of white skin. In severe cases, the whole leaf is withered and white. The damage at the tillering stage affects the normal growth of rice, and the damage in the middle and late stages affects the rice yield more obviously, especially the panicle. In the early stage, the sword leaves were damaged, resulting in an increase i...

AI Technical Summary

Problems solved by technology

At present, due to the unreasonable application of pesticides, rice leaf rollers have developed varying degrees of resistance to commonly used pesticides such as organophosphates and carbamates.

At present, in the actual process of agricultural production, the application of chemical agents is often used as a means of controlling crop pests, but the long-term use of the same chemical agent for prevention and control is likely to lead to the occurrence of "3R" problems such as pest resistance, re-emergence, and pesticide residues.
