Embodiment 1

[0047] Weigh 50g of fenfenozide, 1g of fenbutacarb, 8g of sodium lignosulfonate, 2g of sodium lauryl sulfate, 5g of ammonium sulfate, 5g of polyvinyl alcohol, 2g of borax, and 13g of kaolin, and disperse the above raw materials into granules by water The preparation method forms the water-dispersible granule of fenfenozide·zhongbucarb with the weight percentage of the main active ingredient being 51%.

Embodiment 2

[0049] Weigh 30g of fenfenozide, 1g of fenbucarb, 3g of phenethylphenol polyoxyethylene ether phosphate, and 33 Nongru # 2g, 600#1g, 150# 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 chlorfenozide-zhongbuwei water-based emulsion with a main active ingredient weight percentage of 31%.

Embodiment 3

[0051] Weigh 20g of fenfenozide, 1g of fenbucarb, 6g of calcium dodecylbenzenesulfonate, 3g of phenethylphenol polyoxyethylene ether phosphate, 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 chlorfenozide·zhongbucarb microemulsion with a main active ingredient weight percentage of 21%.

Abstract

The invention discloses a composite insecticidal composition containing chromafenozide and fenobucarb and use thereof, the composite insecticidal composition comprises chromafenozide and fenobucarb as insecticidal active ingredients, and the weight ratio of chromafenozide to fenobucarb is 50:1 to 1:50. The insecticidal composition has the advantages of high synergistic effect, overcoming and delaying of the drug resistance of insect pests, fast insecticidal speed, long holding period, and low cost of administration, and the prevention and cure effect is obviously higher than that of the use of a single agent. Lepidoptera pests on crops can be prevented, the composite insecticidal composition is especially used for the control of cotton bollworm and stem borer, and the effect was significantly 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 fenfenozide and secbucarb as main active ingredients and an application thereof. Background technique [0002] Chromafenozide, chemical name: N-tert-butyl-N'-(3-methoxy-2-methylbenzoyl)-3,5-dimethylbenzoylhydrazide. It is a dihydrazide insecticide, which inhibits the feeding of pests within a few hours after feeding, and at the same time causes the pests to molt early and cause death. Cyclofenozide not only has low toxicity to mammals, birds, and aquatic organisms, but also has no effect on arthropods, predatory acarids, spiders, Hemiptera, Coleoptera (beetles), parasites, and the environment. [0003] Fenobucarb, molecular formula: C 12 h 17 NO 2 . The structural formula is: [0004] [0005] Zhongbuwei is a carbamate insecticide. It has quick effect on rice planthopper, black-tailed leafhopper and rice stink bug with short duration...
