Problems solved by technology

The effect on mite eggs is poor. As a long-term use of acaricide, propargite has produced different degrees of resistance during long-term use, and there is a defect that the control effect is reduced.
[0007] The characteristics of fenazaquin itself have irreplaceable advantages in the control of pest mites, and its own defects restrict its wide application in the control of pest mites to a certain extent.

Embodiment 1

[0016] Example 1: 33% fenazaquin·propargyl acetamide EC

[0017] Fenazaquin 30.30g

[0018] Propargyl 3.16g

[0019] Calcium dodecylbenzene sulfonate (emulsifier) ​​5g

[0020] Phenylethylphenol polyoxyethylene ether (emulsifier) ​​5g

[0021] Xylene (solvent) make up to 100g

[0022] The active ingredients, emulsifiers and co-solvents are added to the mixing kettle in sequence according to the formula ratio, and the mixture is stirred to obtain 33% fenazaquin·propargyl ethyl. (The mass ratio of fenazaquin and propargyl is 10:1)

Embodiment 2

[0023] Example 2: 24% fenazaquin·propargyl mite microemulsion

[0024] Fenazaquin 20.20g

[0025] Propargyl 4.21g

[0026] N-methylpyrrolidone (solvent) 10g

[0027] Calcium dodecylbenzene sulfonate (emulsifier) ​​8g

[0028] Phenethylphenol polyoxyethylene ether (emulsifier) ​​7g

[0029] Deionized water, make up to 100g

[0030] The original medicine, solvent, and emulsifier are added together to dissolve into a homogeneous oil phase, slowly added to water under stirring, and then rapidly inverted by stirring and heating, and cooled to room temperature to prepare 24% fenazaquin·propargyl microemulsion. (The mass ratio of fenazaquin and propargyl is 5:1)

Embodiment 3

[0031] Example 3: 45% fenazaquin·propargyl wettable powder

[0032] Fenazaquin 30.30g

[0033] Propargyl 15.79g

[0034] Sodium lauryl sulfate (wetting agent) 3g

[0035] Alkyl naphthalene sulfonate formaldehyde condensate (dispersant) 5g

[0036] White carbon black (filler) 6g

[0037] Kaolin (filler) up to 100g

[0038] The active ingredients, various auxiliaries and fillers are fully mixed according to the proportion of the formula, and then pulverized by an ultrafine pulverizer to obtain 45% fenazaquin·propargyl wettable powder. (The mass ratio of fenazaquin and propargyl is 2:1)

Abstract

The invention relates to a mite-killing composition comprising the effective components of fenazaquin and propargite, wherein the ratio of the fenazaquin and the propargite in parts by mass is 10:1-1:75. The fenazaquin and the propargite are compounded, which has an obvious synergistic action and can reduce the application quantity and delay the drug resistance of harmful mites. The invention canbe used for preventing and treating the harmful mites on crops and is especially suitable for preventing and treating the harmful mites on fruit trees, cotton and vegetables.

Description

Technical field [0001] The invention relates to an acaricidal composition, specifically a synergistic acaricidal composition compounded with fenazaquin and another acaricidal active ingredient, which is applied to the prevention and control of harmful mites on crops. Background technique [0002] Mite pests have the characteristics of short reproduction cycle, large reproduction volume, high degree of selfing, and obvious generation overlap, and they are easy to develop resistance. Panonychus, Tetranychus cinnabarinus and Tetranychus urticae are the main harmful mites on fruit trees, cotton and vegetables. The compounding of medicaments with different mechanisms of action is one of the main means to solve the problem of resistant pest mites and delay the development of resistance of pest mites. [0003] Fenazaquin: English generic name Fenazaquin, chemical name: 4-tert-butylphenethyl quinazoline, molecular formula: C 20 H 22 N 20 . Its structural formula is: [0004] [0005] The ...
