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 liquid containing lufenuron and carbamate pesticide. Lufenuron and an active ingredient II are compounded to form a chemical component of the ultra-low-volume liquid, and remaining components of the ultra-low-volume liquid include a surfactant and a solvent. The active ingredient II is optionally one of carbosulfan, benfuracarb, nitrilacarb, fenobucarb, isoprocarb, triazamate, pirimicarb, metolcarb, dimethacarb, carbaryl, methiocarb, methomyl or thiodicarb. The ultra-low-volume liquid is convenient to process, long in lasting effect and high in work efficiency, targets cannot generate pesticide resistance easily, the environmental pollution is low, the pesticide and water are saved, the pesticide utilizing rate is improved, and various pests of rice, wheat, corns, vegetables, tobaccos, tea trees, fruit trees and sugarcane can be controlled by 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 lufenuron and carbamate insecticides, mainly through ultra-low-capacity spraying, low-capacity spraying or ultra-low-capacity electrostatic spraying to achieve effective treatment of crop pests. 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 field control effec...
