Embodiment 1

[0022] Weigh 30 g of flumefeline and cis-cypermethrin, 4 g of calcium dodecylbenzenesulfonate, 4 g of phenethylphenol polyoxyethylene ether, and add vegetable oil to 100 g. Put the above raw materials into a mixing tank according to the conventional method for preparing emulsifiable concentrates, and mix them to prepare trifluramine-cis-cypermethrin emulsifiable concentrates with a main active ingredient of 30% by weight. Wherein the specific ratios of flumefeline and cis-cypermethrin are shown in Tables 1 and 2.

[0023] Indoor synergistic bioassay was carried out by feed poisoning method, the resistant cotton bollworm was selected as the target pest, each treatment was repeated 3 times, and 60 heads were treated at each concentration, and the toxicological regression equation and sum of each pesticide resistant cotton bollworm were calculated by the probability value method lethal middle concentration LC 50 , with LC 50 The co-toxicity coefficient was calculated according ...

Embodiment 2

[0033] Weigh 5g trifluroxyfen, 50g cis-cypermethrin, phenethylphenol polyoxypropylene polyoxyethylene ether 3g, agricultural milk 33 ＃ 2g, 600#1g, solvent naphtha 13g, add water to 100g. Put the above raw materials into a mixing tank according to the conventional method for preparing water-based emulsions and mix at high speed to form a trifluramine-cis-cypermethrin water-based emulsion with a main active ingredient of 55% by weight.

Embodiment 3

[0035] Weigh 2g of fluomepyr, 18g of cis-cypermethrin, 6g of calcium dodecylbenzenesulfonate, 3g of phenylethylphenol polyoxypropylene polyoxyethylene ether, and 33 grams of agricultural milk ＃ 2g, agricultural milk 600 # 1g, cyclohexanone 10g, add water to 100g. Put the above raw materials into a mixing tank according to the conventional method for preparing microemulsions, and mix them to form a trifluroxylate-cypermethrin microemulsion with a main active ingredient of 20% by weight.

[0036] Carry out control cotton bollworm drug effect test to embodiment 3, contrast agent is 5% cis-cypermethrin EC and 100g / l flumefeline EC, dilute according to the dilution multiple in table 3, check 3 days, 7 days after medicine , 14-day results, the processing results are shown in Table 3:

Abstract

The invention discloses a compound insecticidal composition containing pyridalyl and alpha-cypermethrin, and application thereof. The insecticidal composition uses pyridalyl and alpha-cypermethrin as insecticidal active components, wherein a weight ratio of pyridalyl to alpha-cypermethrin is 1-80: 1-80. The insecticidal composition can produce high synergistic effect, overcomes and delays pest resistance to insecticide, has a fast insecticidal speed and a long persistent period, reduces insecticidal cost and exerts obviously better prevention and treatment effects compared with prevention and treatment effects of each single insecticide in the composition. The insecticidal composition provided by the invention can prevent and treat lepidoptera pests attacking crops, especially cotton bollworm and stem borers, and has obviously better prevention and treatment effects compared with prevention and treatment effects of each single insecticide in the composition.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition with trifluroxyfen and cis-cypermethrin as main active ingredients and an application thereof. Background technique [0002] Pyridalyl, chemical name: 2-{3-[2.3-dichloro-4-(3,3-dichloro-2-propenyloxy)phenoxy]propoxy}-5 -(trifluoromethyl)pyrimidine, structural formula: [0003] [0004] Triflumepyr, also known as pyridalone, is a new type of pyrimidine insecticide with high efficiency and low toxicity developed by Sumitomo Chemical Company of Japan. It has excellent control effect on Lepidoptera pests. It is different from existing Lepidoptera No cross-resistance to insecticides. It has the effects of contact killing and stomach poisoning, and is mainly used to control Lepidoptera pest larvae that harm crops. In addition, it also has good control effects on Thysanoptera thrips and Diptera leaf miners. [0005] Alphacypermethrin, molecular for...
