Example Embodiment

[0035] Embodiment 1: 22.0% rotenone·chlorantraniliprole emulsifiable concentrate composition and preparation method

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

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

[0038] After the above-mentioned weight ratio raw materials are mixed, an emulsifiable concentrate is made by a traditional emulsifiable concentrate processing method.

Example Embodiment

[0039] Embodiment 2: 22.0% rotenone·chlorantraniliprole microemulsion composition and preparation method

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

[0041] The weight percentage (%) of each component of the adjuvant is: emulsifier, tristyrylphenol ethylene oxide triethanolamine phosphate salt 35.0, polyoxyethylene phenyl phenol ether 35.0; solvent, dimethylformamide 1.0, pyrrolidone 1.0 ; Stabilizer, pyrogallic acid 0.1; antifreeze, ethylene glycol 0.1, glycerol 1.0; water 4.8.

[0042] After mixing the raw materials in the above weight ratio, a traditional microemulsion processing method is used to prepare a microemulsion.

Example Embodiment

[0043] Embodiment 3: 22.0% rotenone·chlorantraniliprole aqueous emulsion composition and preparation method

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

[0045] The weight percentage (%) of each component of the adjuvant is: solvent, xylene 30.0, N-long-chain alkyl pyrrolidone 30.0; emulsifier, 2,4,6-tris(1-phenethyl)phenol poly(20)ethylenedi Alcohol phosphate monoester 4.0; dispersant, polyvinyl alcohol 0.2; antifreeze, glycerol 0.1; water 13.7;

[0046] The pesticide water emulsion is prepared by the traditional water emulsion processing method after the raw materials in the above weight ratio are mixed.

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...
