Embodiment 1

[0124] Example 1: 6% pyridofen-carboxyphenidate (1+5) ultra-low volume liquid

[0125] Weigh 1% pyrazafen, 5% dextate, 5% fatty alcohol polyoxyethylene ether, 3% calcium dodecylbenzenesulfonate, 15% N,N-dimethylformamide, N - Methylpyrrolidone 12%, mesitylene to make up to 100%. In a reactor equipped with electric stirring, the active ingredient is first stirred and dissolved with a solvent at a stirring speed of 100 rpm, then the auxiliary ingredients are added, and the ingredients are fully stirred for 30 minutes to make it evenly mixed to obtain an ultra-low volume liquid.

Embodiment 2

[0126] Example 2: 22% pyrazafen ˙carbafen (2+20) suspension concentrate

[0127] Take by weighing 2g pyraclofen, 20g clofenate technical material, 3g alkylnaphthalenesulfonic acid polycondensate anion sulfonate, 1.5g alkylphenol polyoxyethylene polyoxyethylene polyether formaldehyde condensate sulfate, 1g white carbon black, 0.2g xanthan gum, 5g ethylene glycol, 0.2g sodium benzoate, 0.5g organic silicon, add water to make up to 100g. Add the above-mentioned raw materials into a high-shear emulsifier and shear for 10 minutes, and then grind them with a sand mill to obtain a suspending agent.

Embodiment 3

[0128] Example 3: 44% pyrazafen ˙carbafen (40+4) water dispersible granules

[0129] Take by weighing 40g pyrazafen, 4g clofenate, the sodium salt of 4g alkylnaphthalenesulfonic acid polycondensate, 2g alkylnaphthalenesulfonate and anionic wetting agent mixture, 0.2g sodium benzoate, 19g ammonium sulfate and 15g cornstarch. Mix evenly, after jet crushing, granulate in a granulator, then dry and sieve to obtain granular products.

Abstract

The invention discloses an insecticidal and acaricidal composition comprising cyenopyrafen. The composition comprises the following synergistic compound active components: a component A selected from cyenopyrafen, and a component B selected from mitochondrial respiration inhibitor type insecticidal and acaricidal agents, growth and development inhibitor type insecticidal and acaricidal agents, neurotoxin type insecticidal and acaricidal agents, pyrethroid type insecticidal and acaricidal agents, macrolide type insecticidal and acaricidal agents, carbamate type insecticidal and acaricidal agents, etc. The insecticidal and acaricidal composition provided by the invention is especially suitable to be used for controlling phytophagous mites harming fruit trees, cotton, vegetables and ornamental plants.

Description

technical field [0001] The invention belongs to the field of pesticides. It relates to an insecticidal and acaricidal composition, in particular to an insecticidal and acaricidal composition containing pyraclofen. Background technique [0002] Cyenopyrafen is a new pyrazole acaricide developed by Nissan Chemical Company. Its chemical name: (E)-2-(4-tert-butylphenyl)-2-cyano-1-(1,3,4-trimethylpyrazol-5-yl)alkenyl 2,2 ,-Dimethylpropionate. CAS registration number: 560121-52-0. The structural formula is as follows: [0003] [0004] Cyclopyrafen is a contact acaricide, which is activated by metabolizing into a hydroxyl form to produce activity. This hydroxyl form achieves mitochondrial efficacy by disrupting complex II (succinate dehydrogenase) in the respiratory electron transport chain. The results of indoor toxicity test on Tetranychus cinnabarinus showed that pyrafenpyr has high acaricidal activity, and the acaricidal activity of E-form is higher than that of Z-form...
