Problems solved by technology

[0004] At present, the pesticide preparations with pymetrozine as the active ingredient are mainly 25% pymetrozine wettable powder. Crop safety, the inventor accidentally discovered that the mixed use of two types of active ingredients can improve its quick-acting properties, and has a better duration of effect, and a significant synergistic effect, which can reduce the amount of pesticide application, save costs, and slow down the emergence of pest resistance

Embodiment 1

[0025] Weigh 15% pymetrozine, 10% etofenprox, 3% TERSPERSE 4894 (produced by Huntsman, USA), 1% TERSPERSE 2500 (produced by Huntsman, USA), 2% diffusing agent NNO, 0.3% xanthogen Glue, 5% propylene glycol, 0.5% benzoic acid, 0.5% organosilicon defoamer (trade name: s-29 is produced by Nanjing Sixin Applied Chemicals Company), 1% epichlorohydrin, and deionized water are added to 100% by weight share. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare a 25% pymetrozine-etoproxil suspension concentrate.

[0026] In this embodiment, the weight ratio of pymetrozine and etofenproxil can be changed between 1:2-3:1, and the total weight content of the two is still 25%, forming a new embodiment.

Embodiment 2

[0028] Weigh 10% pymetrozine, 10% etofenprox, 4% TERSPERSE 4894 (produced by Huntsman, U.S.), 1.5% TERSPERSE 2500 (produced by Huntsman, U.S.), 2% TERSPERSE2425 (produced by Huntsman, U.S. ), 0.2% magnesium aluminum silicate, 5% ethylene glycol, 0.5% formaldehyde, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Company), 2% triphenyl phosphate, Deionized water was added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare a 20% pymetrozine-etoproxil suspension concentrate.

[0029] In this embodiment, the weight ratio of pymetrozine and etofenproxil can be changed between 1:2-3:1, and the total weight content of the two is still 20%, forming a new embodiment.

Embodiment 3

[0031] Weigh 30% pymetrozine, 10% etofenprox, 5% TERSPERSE 4894 (produced by Huntsman, U.S.), 2% TERSPERSE 2500 (produced by Huntsman, U.S.), 3% TERSPERSE2425 (produced by Huntsman, U.S. ), 0.2% xanthan gum, 5% propylene glycol, 0.5% benzoic acid, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Company), 1% epichlorohydrin, deionized Water is added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 40% pymetrozine-etoproxil suspension concentrate.

[0032] In this embodiment, the weight ratio of pymetrozine and etofenproxil can be changed between 1:2-3:1, and the total weight content of the two is still 24%, forming a new embodiment.

Abstract

The invention discloses an insect-killing composition containing pymetrozine and etofenprox, comprising the effective active components of the pymetrozine and the etofenprox, wherein the weight ratioof the pymetrozine to the etofenprox is 1:2-3:1. The invention has reasonable components, good insect-destroying effect, low application cost, high quick-acting property, long lasting period and goodsafety without pollution on crops, little residual quantity of a preparation and obvious synergistic action, delays the generation of resistibility, and conforms to the safety requirement of a pesticide preparation; and the activity and the insect-killing effect of the invention are not the simple superposition of the activity of the components. The invention has the preventing effect of 84.24-96.22% to paddy rice planthopper after being applied 14 days.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition composed of pymetrozine and etofenprox as effective active ingredients and application thereof, and belongs to the technical field of compound pesticides. Background technique [0002] Pymetrozine (English common name pymetrozine, chemical formula C 10 h 11 N 5 O) The mechanism of action is that after the adult and the nymph come into contact, the stylet blocking effect will be produced, the feeding will be stopped, and the damage will be caused, and starvation will cause death. The control features are slow action speed, long duration, and no cross-resistance with many existing insecticides. It can control most of the Homopteran pests, especially Aphididae, Amylopidae, Leafhoppers and Planthoppers. Pest pests, suitable for vegetables, rice, cotton, fruit trees and a variety of field crops. However, in the actual application process, the single dose o...
