Abstract
The invention relates to a suspending agent containing abamectin and fluopyram. The suspending agent is prepared from the following components in percentage by weight: 1 to 10 percent of abamectin, 1 to 10 percent of fluopyram, 1 to 8 percent of dispersing agent, 1 to 8 percent of wetting agent, 1 to 6 percent of antifreezing agent, 0.3 to 3 percent of thickening agent, 0.05 to 1 percent of defoaming agent, 0.05 to 2 percent of preservative and the balance of water. Wherein the dispersing agent is selected from a mixture of styrene, ethylene oxide segmented copolymer phosphate ester and soprophor SC; the wetting agent is selected from the group consisting of LUTENSOL TO 8. The suspending agent formula obtained by screening specific auxiliaries has excellent physicochemical properties such as suspension rate and stability through determination, which is beneficial to the shelf stability of pesticides, the utilization rate of the pesticides after application, the exertion of pesticide effects and other aspects. In addition, through biological assay, the suspending agent has an excellent prevention and treatment effect on cucumber root-knot nematode.
Description
technical field [0001] The invention relates to the field of agriculture, in particular to a suspending agent containing abamectin and fluopyram, and its application in preventing and treating root-knot nematode of cucumber. Background technique [0002] Abamectin is a macrocyclic lactone compound with insecticidal, acaricidal and nematicidal activities. It has contact killing and stomach poisoning effects and strong penetration. Abamectin can be absorbed by the soil in the soil, is not easy to understand, and has been decomposed by microorganisms, and has no accumulation effect in the environment. In addition, the cross-resistance between abamectin and other pesticides was low. Therefore, it is widely used in agricultural production. [0003] Fluopyram is a succinate dehydrogenase inhibitor fungicide and nematocide developed by Bayer Crop Science Company. It has the characteristics of high efficiency, green and low toxicity. [0004] CN 107509734A discloses a nematocidal...
