Problems solved by technology

[0004] At present, commonly used tobacco germination inhibitors have 38% trifluralin emulsifiable concentrate, etc., but on the one hand, it is an emulsifiable concentrate preparation, which not only affects the quality of tobacco leaves, but also pollutes the environment, and there are potential safety hazards in storage and transportation; on the other hand, due to Trifluralin is easy to photolyze, so when it is applied to tobacco, a considerable part of the active ingredients will decompose, the utilization rate is low, and the effect is not ideal

Abstract

The invention relates to prodiamine water dispersible granule serving as a tobacco suckercide, wherein the concentration of the applied suckercide liquor is 100-3000ppm, preferably 500-2000ppm, and more preferably 1000-2000ppm. The prodiamine water dispersible granule comprises the following ingredients in percentage by weight: 12.5 to 75 percent of prodiamine, 2 to 15 percent of dispersing agent, 2 to 15 percent of wetting agent, 5 to 25 percent of disintegrating agent, 0.5 to 10 percent of binding agent, 0.5 to 5 percent of stabilizing agent and the balance carrier.

Description

technical field [0001] The invention relates to the application of the amfluralin water-dispersible granule as a tobacco bud suppressant, which belongs to the field of plant protection. Background technique [0002] At present, in tobacco planting, artificial topping is required from the budding growth stage to the early flowering stage to prevent it from growing excessively and ensure the quality and yield of tobacco leaves. (commonly known as axillary buds) grow rapidly, which seriously affects the quality and yield of tobacco leaves. If it is removed manually, the efficiency is low. [0003] Tobacco bud suppressant is a plant growth regulator that can inhibit the growth of tobacco lateral buds and transfer most of the nutrients of tobacco plants to tobacco leaves, so as to improve the quality and yield of tobacco leaves. [0004] At present, commonly used tobacco germination inhibitors have 38% trifluralin emulsifiable concentrate, etc., but on the one hand, it is an em...
