Problems solved by technology

[0006] However, pests such as cotton bollworm and stem borer have gradually increased their resistance under the current long-term use of pesticides, and the effect of single-dose pesticides on pest control has gradually declined.
The inventors have found through research that the synergistic compounding of pesticides is an effective measure to expand the control spectrum and improve the control effect. So far, no insecticidal composition related to trifluroxyfen and chlorfenozide has been found.

Embodiment 1

[0021] Weigh a total of 30 g of fluomepyr and fenfenozide, 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 EC, and mix them to prepare Meflufen-Cenfenozide EC with a main active ingredient of 30% by weight. Wherein the specific ratio of trifluroxyfen and fenfenozide is shown in Tables 1 and 2.

[0022] 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 to Sun Yunpei method, and the results are shown in Table...

Embodiment 2

[0032] Weigh 5g of trifluroxyfen, 50g of fenfenozide, 3g of phenylethylphenol polyoxypropylene polyoxyethylene ether, and Nongru 33 ＃ 2g, agricultural milk 600 # 1g, mineral spirits 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 them at high speed to form a trifluroxyfen·cyclafenozide water-based emulsion with a main active ingredient of 55% by weight.

Embodiment 3

[0034] Weigh 2g of flumepyr, 18g of fenfenozide, 6g of calcium dodecylbenzenesulfonate, 3g of phenylethylphenol polyoxypropylene polyoxyethylene ether, and 33 grams of agricultural milk. ＃ 2g, 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 trifluroxyfen·cyclenfenozide microemulsion with a main active ingredient of 20% by weight.

[0035] Carry out control cotton bollworm drug effect test to embodiment 3, contrast agent is 24% cyclofenozide SC and 100g / l trifluramine EC, dilute according to the dilution multiple in table 3, check 3 days after medicine, 7 Day, the result of 14 days, the processing result is shown in Table 3:

Abstract

The invention discloses a composite insecticidal composition containing pyridalyl and chromafenozide and application thereof. The insecticidal composition employs active components of pyridalyl and chromafenozide in the weight ratio of 0.1-80:0.5-80. The insecticidal composition can produce high synergetic effects, overcomes and delays the insect resistance, and has high insecticidal speed, long effective period, reduced cost of medication and control effect obvious higher than that of a single dose. The invention can control lepidoptera pests of crops, especially can be used for the control of cotton bollworm and snout moth's larva, and the effect is obviously higher than that of the single dose.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition with trifluroxyfen and fenfenozide 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] Chromafenozide, chemical name: N-tert...
