Problems solved by technology

Leafy vegetables in South China and other places, especially in Guangdong and Hainan, are planted all year round. There is basically no seasonal restriction. Flea beetle flavum has overlapping generations and occurs all year round. It is used 3-5 times a month, and about 8-10 times during the peak period. , the development of resistance is very fast, and the dosage of medicine is increasing continuously, which brings a load to the environment, increases the burden on farmers, and wastes resources

Embodiment 2

[0020] Formulation example 2: 20% cyantraniliprole-pyridaben wettable powder.

[0021] According to cyantraniliprole 16%, pyridaben 4%, wetting agent pull-off powder 3%, dispersant naphthalenesulfonate formaldehyde condensate 7%, filler talcum powder 5%, and the balance is filler kaolin. The above formula is coarsely pulverized in proportion, put into a mixer and mixed uniformly, and then jet pulverized to obtain 20% cyantraniliprole-pyridaben wettable powder.

[0022] Formulation Example 3: 12% cyantraniliprole·pyridaben microemulsion.

[0023] According to cyantraniliprole 3%, pyridaben 9%, emulsifier 6014%, emulsifier NP-104%, emulsifier 1602#3%, cyclohexanone 3%, xylene 4%, the balance is deionized water . Dissolve the original drug, solvent, and emulsifier in the above formula into a uniform oil phase, slowly add it into deionized water under stirring, then rapidly invert the phase after stirring and heating, and cool to room temperature to prepare 12% cyantraniliprole ...

Embodiment 5

[0026] Formulation Example 5: 60% cyantraniliprole·pyridaben water-dispersible granules.

[0027] According to cyantraniliprole 20%, pyridaben 40%, sodium lauryl sulfate 2%, polycarboxylate 2%, sodium chloride 8%, polyethylene glycol 4%, the balance is kaolin. Dry pulverize, granulate, dry and sieve the above formula in proportion to prepare 60% cyantraniliprole-pyridaben water-dispersible granules.

Embodiment 1

[0028] Biological Assay Example 1: Indoor joint toxicity test of cyantraniliprole and pyridaben against Flea beetle.

[0029] The co-toxicity coefficient (CTC value) of the mixture was calculated according to Sun Yunpei's method.

[0030] Measured toxicity index (ATI) = (standard drug LC 50 / Test agent LC 50 )×100.

[0031] Theoretical toxicity index (TTI) = toxicity index of agent A × percentage content of A in the mixture + toxicity index of agent B × percentage content of B in the mixture.

[0032] Co-toxicity coefficient (CTC) = [measured toxicity index (ATI) of mixture / theoretical toxicity index (TTI) of mixture]×100.

[0033] According to the classification standard of NY / T11547.7-2006 combined action of insecticides: co-toxicity coefficient (CTC) ≥ 120 means synergistic effect; co-toxicity coefficient (CTC) ≤ 80 means antagonism; 80 < co-toxicity coefficient (CTC) )<120 shows an additive effect.

[0034] Table 1 of the test results shows that when pyridaben and cya...

Abstract

The invention discloses a sterilization composition containing cyantraniliprole and pyridaben. The sterilization composition comprises a common auxiliary agent, cyantraniliprole, and pyridaben. Weight ratio of cyantraniliprole to pyridaben ranges from 1:10 to 10:1; and the total weight of cyantraniliprole and pyridaben accounts for 5 to 70% of the weight of the sterilization composition. The sterilization composition is used for preventing and treating crop flea beetle; fast-acting properties and durable effects of the sterilization composition are better than that of signal agents; using amount of pesticide is reduced; application cost is reduced; and the sterilization composition is beneficial for environmental protection and agricultural insect comprehensive control.

Description

technical field [0001] The invention relates to a pesticide composition containing cyantraniliprole and pyridaben, which is used for preventing and controlling pesticide crop flea beetles, and belongs to the technical field of pesticides. Background technique [0002] Pyridaben, English name: pyridaben, Pyridaben is a broad-spectrum, contact insecticide and acaricide. It can knock down pests quickly and can control agricultural pests such as whitefly, tea leafhopper, flea beetle, and red spider. . [0003] Cyantraniliprole, English name: cyantraniliprole, is a second-generation ryanodine receptor inhibitor insecticide. Cyantraniliprole is made by changing various polar groups on the benzene ring, which is more efficient, It is applicable to a wider range of crops and can effectively control pests of Lepidoptera, Hemiptera and Coleoptera. [0004] Flea beetle is a pest of Coleoptera and Chrysophyllidae, commonly known as dog lice, fleas, referred to as flea beetles, and oft...
