Embodiment 1

[0021] Weigh 2% bifenthrin, 30% triazophos, 3% TERSPERSE 2425 (produced by Huntsman, USA), 3% tristyrylphenol polyoxyethylene ether phosphate, 2% agricultural milk 2201#, 1 %TERSPERSE 2500 (produced by Huntsman, USA), 10% xylene, 0.3% xanthan gum, 5% propylene glycol, 0.5% benzoic acid, 0.5% silicone defoamer (trade name: s-29 Nanjing Sixin Application Chemical company), 1% epichlorohydrin, and deionized water are added to 100% by weight. Triazophos, triphenylethylphenol polyoxyethylene ether phosphate, Nongru 2201#, xylene, and epichlorohydrin in the above raw materials are mixed and dissolved evenly, and then put into bifenthrin, TERSPERSE 2425, TERSPERSE2500, yellow In the mixed phase of raw gum, propylene glycol, benzoic acid, silicone defoamer, and deionized water, disperse at high speed for 30 minutes, and grind with a sand mill to prepare 33% bifenthrin triazophos suspoemulsion .

[0022] In this embodiment, the weight ratio of bifenthrin and triazophos can vary from ...

Embodiment 2

[0024] Weigh 5% bifenthrin, 15% triazophos, 6% calcium lignosulfonate, 3% alkylnaphthalene sulfonate formaldehyde condensate (diffusion agent NNO), 1% sodium lauryl sulfate, 30 % white carbon black, kaolin added to 100% by weight. After the above raw materials are mixed except triazophos, the triazophos is sprayed and adsorbed, mixed uniformly, pulverized by ultra-fine airflow, and mixed to prepare 20% bifenthrin·triazophos wettable powder.

[0025] In this embodiment, the weight ratio of bifenthrin and triazophos can vary from 1:3 to 1:30, and the total weight content of the two is still 20%, forming a new embodiment.

Embodiment 3

[0027] Weigh 1% bifenthrin, 25% triazophos, 6% calcium lignosulfonate, 4% alkylnaphthalene sulfonate formaldehyde condensate (diffusion agent NNO), 1.5% sodium lauryl sulfate, 40 % white carbon black and diatomaceous earth are added to 100% by weight. After the above raw materials are mixed except triazophos, the triazophos is sprayed and adsorbed, mixed evenly, pulverized by ultra-fine airflow, and mixed to prepare 26% bifenthrin·triazophos wettable powder.

[0028] In this embodiment, the weight ratio of bifenthrin and triazophos can vary from 1:3 to 1:30, and the total weight content of the two is still 26%, forming a new embodiment.

Abstract

The invention discloses an insecticidal composition containing bifenthrin and triazophos, comprising the following components by weight ratio of 1:3-1:30: A) a first active ingredient bifenthrin, and B) a second active ingredient triazophos. The composition has reasonable components, good insect-killing effect, low drug cost, high quick action, long effect endurance, resistance alleviation, a small quantity of preparation residues, no pollution to crops, good safety, and conformity to the security requirement of a pesticide preparation; and activity and insect-killing effect of the composition are not simple superposition of activities of the components but obvious enhanced effect. The composition respectively has the control effect of 91.06%-98.25% and 89.27%-98.99% after applying 7d to small aphids in a field and red spiders.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition containing bifenthrin as the first active ingredient and triazophos as the second active ingredient and application thereof, belonging to the technical field of compound pesticides. Background technique [0002] Bifenthrin (English common name bifenthrin, chemical formula C 23 h 22 CIF 3 o 2 ) is a pyrethroid insecticide and acaricide. It has contact killing and stomach poisoning effects, no systemic and fumigation effects, wide insecticidal spectrum and rapid action. It does not move in the soil and is safer for the environment. It is suitable for controlling pests and mites such as Lepidoptera larvae, whiteflies, aphids, leafminers, leafhoppers, and spider mites on wheat, cotton, fruit trees, vegetables, tea and other crops. It is used to save time and medicine when insects and mites are concurrent. However, in the actual application process, if ...
