Embodiment 1

[0019] Preparation method example 1: 20% flufenazine spirodiclofen suspension concentrate

[0020] Weigh 10% spirodiclofen, 10% flufenazine, 5% methylnaphthalenesulfonic acid formaldehyde condensate, 0.3% xanthan gum, 1.5% bentonite, 1% agricultural milk 600#, 2% agricultural milk 500#, 5 % ethylene glycol, deionized water to make up to 100%. The above raw materials were mixed, dispersed at high speed for 30 minutes, and ground with a sander to prepare a 20% flufenazine-spirofen-diclofen suspension.

Embodiment 2

[0021] Preparation method example 2: 40% flufenazine spirodiclofen wettable powder

[0022] Weigh 25% spirodiclofen, 15% flufenazine, 6% calcium lignosulfonate, 6% pull-off powder BX, 3% K-12, 5% white carbon black, kaolin and add to 100% by weight. The above-mentioned raw materials are mixed and air-jet pulverized to obtain 40% flufenazin-spirofen-diclofen wettable powder.

Embodiment 3

[0023] Preparation method example 3: 40% flufenazine spirodiclofen water dispersible granule

[0024] Weigh 15% spirodiclofen, 25% flufenazine, 8% mineral oil, 6% nonylphenol polyoxyethylene ether, 2% penetrant fast T, 2% sodium dodecylsulfonate, 10% lignin Sodium sulfonate, 5% naphthalene sulfonate, and bentonite are added to 100% by weight. The above raw materials are mixed, pulverized by ultra-fine airflow, mixed and granulated to prepare 40% flufenazine-spirofen-diclofen water-dispersible granules.

Abstract

The invention discloses an anti-mite composition containing flutenzine and spirodiclofen. The effective components of the composition comprise flutenzine and spirodiclofen, and a mass part ratio of flutenzine to spirodiclofen is 1:10-10:1. The composition compounding the two effective components has an obvious synergistic effect, improves the prevention and treatment effect and reduces the use amount of pesticides, so the cost is reduced, and the pollution to environment is reduced. The above pesticide composition is suitable for agriculturally preventing and treating various pest mites.

Description

technical field [0001] The invention relates to an acaricidal composition, which uses flufenazine and spirodiclofen as active ingredients and is used for preventing and controlling agricultural pest mites. Background technique [0002] The mechanism of action of spirodiclofen is to inhibit the fat synthesis in harmful mites. It has no cross-resistance with existing acaricides, and is suitable for controlling harmful mites that are resistant to existing acaricides. The egg killing effect is particularly excellent, and it also has a good contact killing effect on young nymphs. Although mite danger cannot kill female adult mites quickly, it has a good sterilization effect on female adult mites. 96% of the eggs laid by the female adult mites could not hatch and died in the late embryonic stage after being exposed to the pesticide. [0003] Flufenazine is currently the largest acaricide used in Europe. It has good control effects on citrus panonychia, rust mites, tea yellow mit...
