Suspending agent containing terbuthylazine and pyroxasulfone and preparation method thereof

Abstract

The invention provides a suspending agent containing terbuthylazine and pyroxasulfone, which is prepared from the following components in percentage by mass: 40 to 60 percent of active ingredient, 4 to 10 percent of dispersing agent, 1 to 5 percent of wetting agent, 0.1 to 4 percent of thickening agent and 0.2 to 3 percent of defoaming agent, the active ingredients comprise terbuthylazine and pyroxasulfone. Terbuthylazine and pyroxasulfone are compounded to prepare the suspending agent, so that the herbicide controlling spectrum of the suspending agent is expanded. By optimizing the dispersing agent, the problems that the product is high in viscosity and easy to paste and form the bottom during storage are effectively solved, by optimizing the wetting agent and the anti-freezing agent, the problem of product skinning is solved, meanwhile, the stability of the product under the low-temperature condition is improved, and the technical difficulty of a high-content suspending agent is overcome. The prepared suspending agent has a high suspension rate in water, and a proper wetting agent is added, so that the drug-holding amount of the plant surface is increased, the pesticide effect is more remarkable, and meanwhile, the pollution of pesticides to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a suspension agent containing terbutin and fenpyrazole and a preparation method thereof. Background technique [0002] Terbuthylazine, chemical name: 2-chloro-4-terbuthylazine-6-ethylamino-1,3,5-triazine, Terbuthylazine is a selective systemic herbicide, pre-emergent It can be absorbed from the roots, or infiltrated into the plant from the stems and leaves, and transported to the green leaves to inhibit photosynthesis. Generally, it has a better effect on the newly germinated weeds. It is suitable for corn, sorghum, soybean, pome fruit trees, citrus, grapes and other crops. It can control annual broad-leaved and grass weeds. The effect on broad-leaved weeds is better than that of grass weeds, but the effect on perennial weeds is better Difference. [0003] The single use of terbutin has a large amount of use and cannot effectively control broad-leaved weeds. SUMMARY OF THE...

AI Technical Summary

Problems solved by technology

It is suitable for crops such as corn, sorghum, soybean, pome fruit trees, citrus, grapes, etc. It can control annual broad-leaved and gramineous weeds. The effect on broad-leaved weeds is better than that of gramineous weeds, but the effect on perennial weeds Difference

[0003] The single use of terbutyline is relatively large, and it cannot effectively control broad-leaved weeds
