Weeding granule used for paddy field and applicable to prevention and treatment of Hyphantria cunea through aerial application of pesticides

Abstract

The invention discloses weeding granule used for paddy field and applicable to prevention and treatment of Hyphantria cunea through aerial application of pesticides. The weeding granule is characterized by comprising 0.2%-20% of effective ingredients, 0.1%-0.5% of a wetting agent, 1%-5% of a dispersing agent, 0.5%-5% of an emulsifying agent, 0.5%-2% of a binding agent, 0.1%-0.5% of a warning color, with the balance being a carrier, wherein the total content of active components accounts for 0.2-20% of the granule. The granule is characterized in that the diameter of the granule is in a range of 1-4 mm, the specific gravity of the granule is 0.9-1.5 g / cm<3>, and the granule has an anti-drifting effect, and can be applied by an unmanned aerial vehicle after transplanting, thereby reducing labor intensity and improving working efficiency.

Description

technical field [0001] The invention belongs to the field of agrochemicals, and in particular relates to a novel operating mode of low-altitude and machine-spreading herbicides for controlling weeds. Background technique [0002] At present, the main dosage forms of paddy field herbicides used for soil sealing include wettable powder, emulsifiable concentrate, granule, effervescent tablet, floating granule, water emulsion, etc., and the application methods include soil mixing, fertilizer mixing, water spraying, direct spraying, etc. Shi et al. Regardless of the operation method, a large amount of labor costs will be consumed. However, in the current situation of shortage of labor resources, we urgently need a pesticide formulation suitable for mechanized operations. Flying defense operation is an effective measure for field mechanized operation, and has the advantages of low cost, high efficiency, less pollution, and high utilization rate. At present, the method of aerial ...
