Problems solved by technology

The above two herbicides are used in a large amount. If the amount of use is small, the effective herbicide effect cannot be achieved, and some weeds and miscellaneous shrubs have developed resistance and cannot be controlled by a single agent for a long time.

Abstract

The invention provides a sterilant herbicide. The effective constituents in the herbicide are hexazinone and glyphosate, the weight ratio of the hexazinone to the glyphosate is 1:1.5-15, the total weight of the hexazinone and the glyphosate accounts for 10% to 90% of the total weight of the herbicide, and the balance is pesticide assistants. The sterilant herbicide is used for controlling perennial vines, undershrub weeds and woody plants of wastelands, railways and forest-fire-prevention isolation belts and controlling annual and perennial weeds. Pesticide efficacy experiments when the hexazinone and the glyphosate are compounded show that the complementarity of the effective constituents is mainly shown that the weed-and-miscellaneous-shrub pesticide resistance generated when a single herbicide is used for a long time is avoided, the herbicide controlling spectrum is amplified, the using rate of the herbicide is increased, the dosage is reduced, and the fast-acting property and the persistence of the herbicide are improved. In this way, when the hexazinone and the glyphosate are compounded, the synergistic effect is remarkable, and the persistence period is long.

Description

technical field [0001] The invention belongs to the field of agricultural plant protection, and in particular relates to a destructive herbicide. Background technique [0002] At present, with the increase of the population and the development of the market economy, the cost of labor is getting higher and higher, especially the repeated input of manpower in the public domain has caused a lot of waste of human resources. The present invention aims to change artificial weed control to chemical control to reduce labor Cost, increase the quick effect and duration of weed control. At present, hexazinone and glyphosate are herbicides that can effectively treat weeds in the market. Among them, glyphosate is a non-selective, non-residual herbicide that inhibits enolacetonyl shikisinate in plants. Acid synthase, thereby inhibiting the conversion of shikimelin to phenylalanine, tyrosine and tryptophan in plants, which interferes with protein synthesis and leads to the death of weeds....
