Problems solved by technology

[0003] Among the existing plants, red spider mite, cinnabar spider mite, and two-spotted spider mite are the most common insect pests. They are not only easy to infect, but also spread and reproduce very fast. If they are not treated properly, they will cause serious damage to plants; A large number of pesticides suitable for acarid pests have appeared. However, after the insect pests have been eliminated, their resistance to pesticides has become stronger and stronger, resulting in a gradual decline in the control effect of a single dose of acaricides.

Embodiment 1

[0033] Example 1: Preparation of 28% Acynonapyr and Ethofenazole EC

[0034] Add 20 parts of Acynonapyr, 8 parts of ethiprofen, 6 parts of agricultural milk 500#, 5 parts of agricultural milk 600#, 5 parts of N-methylpyrrolidone, solvent oil S-150 to 100 parts, stir and mix After homogenization, 28% Acynonapyr and ethiprole EC can be obtained.

[0035] In addition, the ethifenapyr was replaced with one of the compounds described in the cost specification, cyfenpyrafen, cyflufenapyr, ZJ-31169, and bifenazate, to form a new series of emulsifiable concentrates containing Acynonapyr.

Embodiment 2

[0036] Embodiment 2: the preparation of 20% Acynonapyr and pyraclofen in water emulsion

[0037] Add 18 parts of Acynonapyr, 2 parts of nitrile pyraclofen, 5 parts of N,N-dimethyldecylamide, 10 parts of cyclohexanol, 5 parts of glycerin, 5 parts of phenylethylphenol polyoxyethylene ether, 5 parts 100 parts of castor oil polyoxyethylene ether, after mixing uniformly, add water to make up to 100 parts, stir and mix uniformly to obtain 20% Acynonapyr and pyraclofen in water emulsion.

[0038] In addition, pyrfenapyr was replaced with one of ethifenapyr, cyflufenapyr, ZJ-31169, and bifenazate described in the cost specification to form a new series of aqueous emulsions containing Acynonapyr.

Embodiment 3

[0039] Embodiment 3: the preparation of 18% Acynonapyr and bifenazate microemulsion

[0040] Add 15 parts of Acynonapyr, 3 parts of bifenazate, 4 parts of alkyl vinyl aryl phenyl ether, 2 parts of agricultural milk 100#, 6 parts of diphenylphenol polyoxyethylene ether formaldehyde condensate, 6 parts 1 part of Nongru OX-2681, 10 parts of N-methyl-pyrrolidone, 5 parts of tributyl phosphate, mix well, add water to make up to 100 parts, continue stirring at high speed to obtain well-dispersed 18% Acynonapyr and bifenazate micro emulsion.

[0041] It is also possible to replace bifenazate with one of the pyrfenapyr, ethifenapyr, cyflufenapyr, and ZJ-31169 described in the cost specification to form a new series of microemulsions of Acynonapyr.

Abstract

The invention provides an acaricidal composition, which comprises an active component A and an active component B. The active component A is Acynapyr, and the active component B is one or more of etoxazole nitrile, cyenopyrafen, cyflumetofen, ZJ-31169 and bifenazate. The invention also discloses an application of the acaricidal composition in preventing and treating plant insect pests. The components in the acaricidal composition have a strong synergistic effect, and the drug resistance of acarid pests can be delayed. By applying the composition, the pharmaceutical composition provided by theinvention has the advantages of being small in dosage and good in prevention effect.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an acaricidal composition and application thereof. Background technique [0002] Insect pests are common diseases in the process of plant growth. Their impact on plants runs through the entire life cycle of plants. Insect pests not only affect the lifespan of the plants themselves, but also have an important impact on the yield of crops. In severe cases, they can lead to crop failure. [0003] Among the existing plants, red spider mite, cinnabar spider mite, and two-spotted spider mite are the most common insect pests. They are not only easy to infect, but also spread and reproduce very fast. If they are not treated properly, they will cause serious damage to plants; A large number of pesticides suitable for acarid pests have appeared. However, after the pests have been eliminated, their resistance to pesticides has become stronger and stronger, resulting in a gradual decline ...
