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.
Chlorantraniliprole, as a newly listed chemical pesticide, currently 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. In addition, pests are easy to produce pesticides. resistance

Embodiment 1

[0035] Example 1: Composition and preparation method of 22.0% rotenone·chlorantraniliprole EC

[0036] The percentage by weight (%) of each active ingredient of the main agent of this example is: rotenone 2.0, chlorantraniliprole 20.0.

[0037] The weight percent (%) of each component of the auxiliary agent is: solvent, xylene 59.8, methanol 5.0; cosolvent, cyclohexanone 0.2; emulsifier, dibenzylphenol polyoxyethylene ether 8.0. Tween-204.0; stabilizer, pyrogallic acid 0.5, castor oil 0.5.

[0038] The above-mentioned weight ratio raw materials are mixed to make emulsifiable concentrate by traditional emulsifiable concentrate processing method.

Embodiment 2

[0039] Example 2: Composition and preparation method of 22.0% rotenone·chlorantraniliprole microemulsion

[0040] The percentage by weight (%) of each active ingredient of the main agent of this example is: rotenone 2.0, chlorantraniliprole 20.0.

[0041] The weight percent (%) of each component of the auxiliary agent is: emulsifier, tristyrylphenol oxiraneated triethanolamine phosphate salt 35.0, polyoxyethylene phenylphenol ether 35.0; solvent, dimethylformamide 1.0, pyrrolidone 1.0 ; Stabilizer, pyrogallic acid 0.1; antifreeze agent, ethylene glycol 0.1, glycerol 1.0; water 4.8.

[0042] The traditional microemulsion processing method is used to make microemulsion after mixing the raw materials in the above weight ratio.

Embodiment 3

[0043] Example 3: Composition and preparation method of 22.0% rotenone·chlorantraniliprole aqueous emulsion

[0044] The weight percent (%) of each active ingredient of the main agent of this example is: rotenone 2.0, chlorantraniliprole 20.0;

[0045] The weight percentage (%) of each component of the auxiliary agent is: solvent, xylene 30.0, N-long chain alkylpyrrolidone 30.0; emulsifier, 2,4,6-tris(1-phenylethyl)phenol poly(20) ethylene glycol Alcohol phosphate monoester 4.0; dispersant, polyvinyl alcohol 0.2; antifreeze agent, glycerin 0.1; water 13.7;

[0046] After mixing the raw materials in the above weight ratio, the insecticide emulsion in water is prepared by the traditional emulsion-in-water processing method.

Abstract

The invention discloses a pesticide preparation for controlling diamond back moth and other vegetable insect pests, comprising main agent which is mixture of the following active ingredients by weight percent: 0.1-20% of rotenone, 0.1-50.0% of chlorantraniliprole as well as missible oil, microemulsion, emulsion in water or suspending agent and the like which are prepared by the main agent and corresponding auxiliary agent. The pesticide preparation has good characteristics such as permeability, systemic property and the like, has high efficiency for the vegetable insect pests such as the diamond back moth and the like, can be used for controlling the vegetable insect pests such as the diamond back moth and the like at different ages, is thorough in killing insect pests, less in environmental pollution and low in production cost, and is suitable for chemical control of the vegetable insect pests such as the diamond back moth and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to pesticide preparations for controlling vegetable pests such as diamondback moth. Background technique [0002] Diamondback moth (Plutella xylostella L.) 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...
