Abstract

The invention relates to an ultra low-volume liquid containing metaflumizone and an insect growth regulator pesticide. The ultra low-volume liquid comprises an active component compounded of metaflumizone and an active ingredient II, and the balance at least one surfactant and at least one solvent, wherein the active ingredient II is any one of chlorfluazuron, teflubenzuron, triflumuron, flufenoxuron, hexaflumuron, flucycloxuron, penfluron, chlorfluazuron, chlorbenzuron, diflubenzuron, diafenthiuron, RH-5849, buprofezin, fenoxycarb and tebufenozide. The ultra low-volume liquid is convenient for processing, has a long duration of efficacy and high efficacy, does not cause pesticide resistance of targets easily, produces low pollution on the environment, saves pesticides and water, improves a pesticide utilization rate, and realizes control of insect pests damaging paddy, wheat, corn, vegetables, tobacco, tea trees, fruit trees and sugarcane through ultra low-volume spraying, low-volume spraying or ultra low-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 methflumizone and insect growth regulator insecticides, which is mainly used for controlling crop pests through ultra-low-volume spraying, low-volume spraying or ultra-low-capacity electrostatic spraying. effective prevention and treatment. 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...
