Embodiment 1

[0030] Embodiment 1:30% water dispersible granule

[0031] Preparation method: Add the active ingredients ethifenacil and spirodiclofen into the carrier according to the proportion, and add surfactant and other functional additives to it, mix them, and granulate them after jet crushing to obtain water-dispersible granules agent. The main equipments are mixer, jet mill, extrusion granulator.

[0032] Composition ratio: 6% of ethifenacil; 24% of spirodiclofen; 4% of wetting agent sodium lauryl sulfate; 8% of dispersant calcium lignosulfonate; quantity.

Embodiment 2

[0033] Embodiment 2:24% suspending agent

[0034] Preparation method: According to the proportion, mix the active ingredients ethifenacil and spirodiclofen with other wetting and dispersing agents, thickeners, antifreeze agents, preservatives, water, etc., after shearing, add them into a horizontal sand mill for 2 ~ 3 hours of sanding, then add defoamer and continue shearing to obtain a suspension product. The main equipment is mixer, shearing machine, horizontal sand mill.

[0035] Composition ratio: Ethazole 6%; spirodiclofen 18%; wetting and dispersing agent carboxylate + sulfonate 8%; thickener 1%; antifreeze 4%; preservative 0.2%; defoaming Agent 0.2%; water balance.

Abstract

The invention belongs to the field of pesticide acaricides, in particular to an acaricide composition containing ethifenapyr and spirodiclofen. Wherein the weight ratio of ethifenac and spirofen is 50:1-1:50, and the preferred ratio is 10:1-1:10. The composition also includes surfactants and functional auxiliaries, which can be formulated into suspension concentrates, water-dispersible granules, etc., wherein the proportion of active ingredients composed of ethifenapyr and spirodiclofen to the total weight is 10% to 80%. %. The effective compounding of ethifenacil and spirodiclofen can expand the scope of acaricide, enhance adaptability, increase the duration of effect, improve drug efficacy and delay the generation of drug resistance, and can also be used as acaricide in plant growth period. All kinds of harmful mites on rice, apples, vegetables, fruit trees and other crops, especially effective on fruit tree spider mites. This compound product reduces the dosage of pesticides, reduces the residues of pesticides on crops, and reduces environmental pollution.

Description

technical field [0001] The invention relates to the field of agricultural acaricides, in particular to an acaricide composition containing etofenil and spirofen. Background technique [0002] Ethofenazole is a new type of acaricide. Shenyang Kechuang Chemical Co., Ltd. has developed a 30% ethifenac suspension concentrate product, and the active ingredient dosage is 22.5~45g a.i. / hm 2 The control effect on apple spider mites is above 98%, which shows that the pesticide has a remarkable control effect on the prevention and control of acarid pests, and has a good application prospect. At present, its mechanism of action and spectrum of prevention and treatment are still in the research stage. After the physical and chemical properties and safety indicators are perfected, the preparation has a lot of room for development. [0003] Spirodiclofen is a broad-spectrum acaricide with a new mechanism of action, with contact action and no systemic property. It mainly inhibits the fa...
