Example Embodiment

[0022] Example 1:

[0023] Weigh a total of 30 g of trifluoromethyl pyridine and matrine, 4 g of calcium dodecyl benzene sulfonate, 4 g of phenethyl phenol polyoxyethylene ether, and 100 g of vegetable oil. The above raw materials are put into a mixing kettle and mixed according to the conventional method of preparing emulsifiable concentrates to prepare trifluroxyfen·matrine emulsifiable concentrate with a main active ingredient weight percentage of 30%. Among them, the specific ratios of trifluroxyfen and matrine are shown in Tables 1 and 2.

[0024] Using feed poisoning method for indoor synergistic bioassay, select resistant cotton bollworm as the target pest, repeat 3 times for each treatment, and treat 60 heads per concentration. The probability value method is used to calculate the toxicological regression equation and Lethal concentration LC 50 , Use LC 50 The value is calculated by Sun Yunpei's method of co-toxicity coefficient, and the results are shown in Table 1:

Example Embodiment

[0032] Example 2:

[0033] Weigh 5g trifluoromethylpyridine, 50g matrine, 3g phenethylphenol polyoxypropylene polyoxyethylene ether, and agricultural milk 33 # 2g, agricultural milk 600 # 1g, 13g solvent oil, add water to 100g. The above raw materials are put into the mixing kettle for high-speed mixing according to the conventional method of preparing the water emulsion to form the trifluroxylate·matrine water emulsion with the main active ingredient weight percentage of 55%.

Example Embodiment

[0034] Example 3:

[0035] Weigh 2g trifluoromethylpyridine, 18g matrine, 6g calcium dodecylbenzene sulfonate, 3g phenethylphenol polyoxypropylene polyoxyethylene ether, and agricultural milk 33 # 2g, agricultural milk 600 # 1g, 10g cyclohexanone, add water to 100g. The above raw materials are put into a mixing kettle according to the conventional method of preparing a microemulsion and mixed to form a trifluroxyfen·matrine microemulsion with a main active ingredient weight percentage of 20%.

[0036] The efficacy test for controlling cotton bollworm in Example 3 was carried out. The control agents were 4.5% matrine EC and 100g / l fenpyridine EC, diluted according to the dilution factor in Table 3, and checked for 3 days and 7 days after the treatment. , The results of 14 days, the processing results are shown in Table 3:

Abstract

The invention discloses a compound insecticidal composition containing pyridalyl and matrine, and application thereof. The insecticidal composition uses pyridalyl and matrine as insecticidal active components, wherein a weight ratio of pyridalyl to matrine 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 trifluramine and matrine 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] Matrine, molecular formula: C15H24N2O, str...
