Abstract

The invention belongs to the field of agricultural acaricides, and relates to an aqueous suspension which uses active ingredients A and B as acaricidal active components and an application thereof. A kind of suspending agent containing ethifenac composition, the effective active ingredients are active ingredient A and active ingredient B, and the said suspending agent is calculated by weight percentage as 5-70% active ingredient, 1-50% dispersant, 0.5% ~5% wetting agent, 0.5~8% thickener, 0.1~2% defoamer, 1~20% antifreeze, and the balance is water; wherein, the active ingredient A is ethifenapyr, and the active ingredient B is From pyridaben, spirofen or etoxazole, the weight ratio of active ingredient A to active ingredient B is 1:20-20:1. The acaricide composition of the present invention has remarkable synergistic effect, good safety to crops, conforms to the national policy of reducing application and increasing efficiency of pesticides, and is currently an ideal acaricide variety for preventing and controlling harmful mites.

Description

technical field [0001] The invention belongs to the field of pesticide acaricides, and relates to a suspending agent containing an ethifenac composition and an application thereof. Background technique [0002] As we all know, acaricides have obvious effects in controlling agricultural and forestry pests or urban sanitation pests. In recent years, with the continuous improvement of people's requirements for the environment and health, the policy of pesticide use has been developed in the direction of reducing application and increasing efficiency. The quality of pesticide formulations and preparations is a key factor in determining the efficacy and value of pesticide products. If you want to give the active ingredient the best effect, it is particularly important to choose the adjuvant system and dosage that match the active ingredient. At present, there are many reports on the suspending agent of the composition containing ethifenac, mainly as follows: [0003] In terms o...
