However, some species have a limited insecticidal spectrum, which limits the scope of use. A few species are highly toxic to humans and animals and are not safe to use; some pests will develop resistance to carbamate pesticides, and reasonable mixing can overcome the above shortcomings. The chemical names of the carbamate insecticides involved in active ingredient II are as follows:

Abstract
The invention relates to an ultra low volume concentrate containing metaflumizone and carbamate insecticides. The concentrate is characterized in that metaflumizone and an active ingredient II are compounded to form a chemical ingredient; other ingredients comprise a surfactant and a solvent; and the active ingredient II is any one of carbosulfan, benfuracarb, nitrilacarb, fenobucarb, isoprocarb, triazamate, pirimicarb, MTMC, dimethacarb, carbaryl, methiocarb, methomyl and thiodicarb. The concentrate has the following advantages that the concentrate is convenient to process, has long duration and high work efficiency, ensures the targets not to have drug resistance easily, is low in environmental pollution, saves drugs and water, improves the utilization rate of the pesticides and can be used for controlling various pests on rice, wheat, corn, vegetables, tobaccos, tea trees, fruit trees and sugarcanes through ultra low volume spraying, low volume spraying or ultra low volume electrostatic spraying.
Description
technical field [0001] The present invention relates to the field of pesticides, in particular to an ultra-low-volume liquid formulation containing metaflumizone and carbamate insecticides. Effective prevention and control. 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 significantly better than the effect of each single agent. Insecticides containing a single active ingredient often have certain defects...
