Problems solved by technology

For example, when rotenone preparations are used in the field, rotenone is prone to photolysis and hydrolysis in the natural environment, which affects the efficacy and persistence of rotenone, and the control effect on pests is affected to a certain extent.
As a chemical pesticide, flubendiamide has a good control effect on vegetable pests. However, in order to improve the control effect of pesticides on pests, farmers continue to increase the dosage of pesticides, which aggravates the occurrence of pesticide resistance of pests.

Abstract

The invention provides a pesticide preparation for controlling vegetable pests of diamondback moth and the like, which relates to the technical field of pesticides. The main agent of the pesticide preparation is a mixture containing the following active ingredients in percentage by weight: 0.1-2.0% of nicouline and 0.1-50.0% of flubendiamide. The main agent and auxiliary agents are prepared into creams, microemulsions, aqueous emulsion and suspending agents. The pesticide preparation has the properties of good permeability, systemic property and the like, has high efficiency on the vegetable pests of diamondback moth and the like, can control the vegetable pests of diamondback moth and the like in different instars and thoroughly kill the pests, has the advantages of less pollution on theenvironment and low production cost, and is suitable for chemically controlling the vegetable pests of diamondback moth and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide preparation for controlling vegetable pests such as diamondback moth. Background technique [0002] Diamondback moth (Plutella xylostella) is one of the main pests of cruciferous vegetables. It has a wide cross-resistance spectrum, high resistance level, and fast propagation speed, which poses a great threat to vegetable production. At present, resistance to organophosphorus, carbamates, pyrethroids, Bt, avermectins, insect growth regulators, and even plant-derived insecticides have been produced to varying degrees, which is the development of drug resistance. One of the most serious pests. In recent years, some chemical agents and biopesticides with novel action mechanisms have been developed to control Plutella xylostella, such as chlorfenapyr, diafenthiuron, abamectin, etc.; however, the control effect of various agents on Plutella xylostella larvae is still l...
