Abstract

The invention belongs to the field of agricultural miticide and relates to an aqueous suspending agent, taking an effective ingredient A and an effective ingredient B as acaricidal active ingredients,and an application of aqueous suspending agent. An SYP-9625 composition containing suspension agent comprises the effective active ingredients, i.e., the active ingredient A and the active ingredientB and comprises the ingredients in percentage by weight: 5% to 70% of active ingredients, 1% to 50% of dispersant, 0.5% to 5% of humectant, 0.5% to 8% of thickener, 0.1% to 2% of antifoamer, 1% to 20% of antifreezer and the balance of water, wherein the active ingredient A is SYP-9625, the active ingredient B is selected from pyridaben, spirodiclofen and etoxazole, and a weight ratio of the active ingredient A to the active ingredient B is (1: 20) to (20: 1). The acaricide composition disclosed by the invention is remarkable in synergistic effect, is good in safety to crops, is in line with national pesticide application-reducing and synergism policy and is an ideal acaricide variety for preventing and controlling pest mites at present.

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...
