Acaricidal composition containing biphenyl synergistic acaricides

[0063] Example 2. 30% emulsifiable concentrate, effective ingredient ratio 5:1

[0064] Compound A 25%, Abamectin 5%, Nongru 2201# 6%, Nongru 0201B 8%, Cyclohexanone 8%, Solvent oil 150 to make up to 100%.

[0065] Abamectin can also be replaced with spinosyn, spiromesifen, benomyl, diflubenzuron, ethenoxafen, fluazinam, bifenazate, and fluorobutanol in compound B described in the specification. One of dicofen, pyridaben, and spirodiclofen forms a new water emulsion product.

[0066] 2. Preparation of wettable powder

[0067] According to the requirements of the formula, the original medicine, various additives and fillers are fully mixed, and then pulverized by an ultrafine grinder to obtain a processed product.

[0068] Example 3. 50% wettable powder

[0069] Compound A 45%, avermectin 5%, sodium dodecylbenzene sulfonate 1.8%, p-tert-butyl ether 2%, white carbon black 10%, sodium lignin sulfonate 10%, light calcium carbonate supplement To 100%.

[0070] Example 4. 40% wettable powder

[0071] Compound A 38%, abamectin 2%, sodium dodecylbenzene sulfonate 2%, p-tert-butyl ether 2%, white carbon black 5%, sodium lignin sulfonate 10%, light calcium carbonate supplement To 100%.

[0072] Abamectin can also be replaced with spinosyn, spiromesifen, benomyl, diflubenzuron, ethenoxafen, fluazinam, bifenazate, and fluorobutanol in compound B described in the specification. One of dicofen, pyridaben, and spirodiclofen forms a new water emulsion product.
