Problems solved by technology

Insecticides containing a single active ingredient often have certain defects in the control of agricultural pests. Continuous use for multiple times not only makes pests prone to resistance, but also easily causes pollution to food and the environment. Mixing can overcome the above disadvantages

Abstract

The invention relates to ultralow-volume liquid containing lufenuron and organic phosphorus insecticide, which comprises chemical composition, surfactant and solvent. The chemical composition is composed of lufenuron and an active ingredient II. The active ingredient II can be optional one of fenitrothion, dipterex, parathion-methyl, isazofos, pyridaphenthion, quinalphos, triazophos, colophonate, phoxim, fenitrothion, pirimiphos-methyl, fenthion, cyanophos, profenofos, chlorpyrifos-methyl, prothiofos, sulprofos, dimethoate, malathion, methidathion and isocarbophos. The ultralow-volume liquid is convenient in process, long-acting and highly efficient, targets are less apt to resist the ultralow-volume liquid, environment pollution is low, insecticide and water are economized, and insecticide utilization rate is increased. The ultralow-volume liquid can be used for controlling various pests for rice, wheat, corn, vegetables, tobacco, tree trees, fruit trees and sugarcane by ultralow-low spraying, low-volume spraying or ultralow-volume electrostatic spraying.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to an ultra-low-capacity liquid formulation containing lufenuron and organophosphorus insecticides, which can effectively prevent and control crop pests mainly through ultra-low-volume spraying, low-volume spraying or ultra-low-capacity electrostatic spraying . Background technique [0002] At present, for the control of pests that are prone to resistance in agriculture, the main method is to develop new ingredients that have no cross-resistance with existing varieties or the compounding of existing pesticide varieties. The former is due to the high development cost and long cycle required. And the current development speed is far behind the speed of pest resistance. Therefore, it is the best choice to mix existing pesticide varieties with different action mechanisms. If the ratio is reasonable, it can produce a significant synergistic effect, making the field control effect significantl...
