Example Embodiment

[0023] Example 1:

[0024] Weigh a total of 30 g of pyriproxyfen and rotenone, 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 according to the conventional method of preparing emulsifiable concentrates, and are mixed to prepare a triflurane·rotenone emulsifiable concentrate with a weight percentage of 30% of the main active ingredient. The specific ratios of trifluroxyfen and rotenone are shown in Tables 1 and 2.

[0025] 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. Use the probability value method 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:

Abstract

The invention discloses a composite insecticidal composition containing pyridalyl and rotenone and a use thereof. The composite insecticidal composition contains pyridalyl and rotenone as active insecticidal components and a weight ratio of pyridalyl to rotenone is 1-80: 1-80. The composite insecticidal composition can produce good synergism, overcomes and delays insect resistance to pesticides, has a fast insecticidal rate and a long persistent period, reduces a pesticide cost and has prevention and control effects obviously higher than that of a single-ingredient pesticide. The composite insecticidal composition can prevent and control lepidoptera pests of crops, especially can be used for preventing and controlling cotton bollworm and stem borers and has effects obviously higher than that of a single-ingredient pesticide.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a pesticide with trifluramine and rotenone as main active ingredients. [0002] Insect compositions and applications thereof. Background technique [0003] Pyridalyl, chemical name: 2-{3-[2.3-dichloro-4-(3,3-dichloro-2-propenyloxy)phenoxy]propoxy}-5 -(trifluoromethyl)pyrimidine, structural formula: [0004] [0005] 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. [0006] Rotenone (rotenone), structural formula:...
