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. Up to now, no insecticidal composition related to trifluroxyfen and chlorantraniliprole has been found.

Embodiment 1

[0021] Weigh a total of 30 g of fluomepyr and chlorantraniliprole, 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·Chlorantraniliprole EC with a main active ingredient of 30% by weight. Wherein the specific ratio of triflumepyr and chlorantraniliprole 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 resul...

Embodiment 2

[0032] Weigh 5g trifluroxyfen, 50g chlorantraniliprole, 3g phenylethylphenol polyoxypropylene polyoxyethylene ether, agricultural milk 33 ＃ 2g, 600#1g, solvent naphtha 13g, add water to 100g. The above raw materials are put into a mixing tank according to the conventional method for preparing water-based emulsions and mixed at high speed to form a trifluroxyfen-chlorantraniliprole water-based emulsion with a main active ingredient of 55% by weight.

Embodiment 3

[0034] Weigh 2g of flumepyridine, 18g of chlorantraniliprole, 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 trifluroxyfen·chlorantraniliprole microemulsion with a main active ingredient of 20% by weight.

[0035] Carry out control cotton bollworm drug effect test to embodiment 3, control agent is 20% chlorantraniliprole SC and 100g / l trifluramine EC, dilute according to the dilution multiple in table 3, check 3 days after medicine, The results of 7 days and 14 days, the processing results are shown in Table 3:

Abstract

The invention discloses a compound insecticidal composition containing pyridalyl and chlorantraniliprole and a use thereof; the insecticidal composition takes pyridalyl and chlorantraniliprole as insecticidal active ingredients, wherein the weight ratio of pyridalyl to chlorantraniliprole is (0.1-80):(0.5-80). The insecticidal composition can generate higher cooperative synergism, overcomes and delays insect pest drug resistance, is fast in insecticidal speed and long in effect preserving period, reduces the drug using cost, and has the prevention and treatment effect significantly higher than that of use of single agents. The insecticidal composition can prevent and treat generated lepidoptera pests on crops, particularly can be used for prevention and treatment of cotton bollworm and stem borers, and has the effect significantly higher than the effect of use of the single agents.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition with trifluroxyfen and chlorantraniliprole 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] Chlorantraniliprole, chemical...
