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.
Cyclofenozide, as a newly listed chemical pesticide, currently has a good control effect on aphids. However, in order to improve the control effect of the pesticide on aphids, farmers continue to increase the dosage of the pesticide. In addition, the aphids are prone to resistance to the pesticide.

Abstract

The invention relates to a pesticide formulation capable of preventing and treating spodoptera exigua, in particular to an insecticidal pesticide formulation containing a biological pesticide namely rotenone, as well as a preparation method and application of the insecticidal pesticide formulation, and belongs to the technical field of pesticides. The insecticidal pesticide formulation containing the biological pesticide namely the rotenone is prepared from active ingredients of the rotenone and chromafenozide, and the balance being an auxiliary agent, wherein the rotenone accounts for 0.1-30.0% of the total weight of the pesticide formulation, the chromafenozide accounts for 0.1-30.0% of the total weight of the pesticide formulation, and the balance is the auxiliary agent. The preparation formulation of the pesticide formulation is aqueous emulsion or a suspending agent. The preparation method of the pesticide formulation comprises the following steps of mixing and compounding the raw materials in a weight ratio so as to obtain a mixture, and making the mixture into the aqueous emulsion or the suspending agent by a processing method of a conventional aqueous emulsion or a conventional suspending agent. The invention further provides the application of the insecticidal pesticide formulation containing the biological pesticide namely the rotenone. A main agent is made into the aqueous emulsion and the suspending agent, the prepared medicament is high-efficiency on the spodoptera exigua, the spodoptera exigua is killed thoroughly, little environmental pollution is generated by using the medicament, the production cost is low, and the pesticide formulation is suitable for preventing and treating the spodoptera exigua.

Description

technical field [0001] The invention relates to a pesticide preparation for controlling beet armyworm, in particular to an insecticidal pesticide preparation containing biological pesticide rotenone, a preparation method and application thereof, and belongs to the technical field of pesticides. Background technique [0002] Beet armyworm (Spodoptera exigua) belongs to Lepidoptera Noctuidae, is a worldwide distribution of polyphagous important agricultural pests, distributed from 40°-57° north latitude to 35°-40° south latitude, in Asia, There are records of damage in North America, Europe, Australia and Africa, mainly harming vegetables, cotton, peanuts, tobacco, corn, soybeans and 138 species of 108 genera in 35 families, especially vegetables. Before the 1980s, the beet armyworm only occurred in some areas of my country. At present, it has occurred in more than 20 provinces, municipalities, and autonomous regions in my country. The area covers South China, East China, Cent...
