Problems solved by technology

In terms of herbicide damage detoxification research, the current methods are: washing with water, early application of seedling fertilizer, topdressing quick-acting fertilizer, strengthening intertillage loosening, and application of special antidotes (such as isoxadifen, cyprosulfonamide, pyridoxine, etc.) Metofen-pyrrofen, Jieduquine, naphthylamine, etc.), spraying alkaline substances such as baking soda water, etc., but the above methods can only alleviate the slight herbicide damage, and basically have no effect on the severe herbicide damage
And the above-mentioned methods are all remedial measures taken after the herbicide injury occurs, and do not fundamentally solve the problem of the herbicide injury

Abstract

The invention discloses a gibberellic acid-containing herbicide composition and a preparation method as well as application thereof. The gibberellic acid-containing herbicide composition is prepared from the following components in parts by weight: 0.01 to 99 parts of gibberellic acid and 1 to 90 parts of herbicide; the herbicide is one or a mixture of at least two of cyhalofop-butyl, penoxsulam, metamifop, bispyribac-sodium, quinclorac, anilofos, pretilachlor, butachlor, mefenacet, bensulfuron methyl, pyrazosulfuron-ethyl, pyriminobac-methyl, bentazone, mesotrione, halosulfuron-methyl, metolachlor, pendimethalin, oxadiazon, oxadiargyl, MCPa, fluroxypyr and diflufenican. The gibberellic acid-containing herbicide composition has synergism to weed prevention and control, the weed control efficiency is improved, the safety of the herbicide to crops can be improved, the herbicide phytotoxicity problem in agricultural production is fundamentally solved, and meanwhile the crop yield is improved by adjusting crop growth.

Description

technical field [0001] The invention relates to a herbicide composition, in particular to a gibberellic acid-containing herbicide composition and its preparation method and application. Background technique [0002] Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, a class of substances used to eliminate or inhibit plant growth. Herbicides are widely used in agriculture because of their low cost, high efficiency, easy operation, labor saving, and obvious weed control effects. However, improper use of herbicides often causes phytotoxicity to crops. When herbicides are used Excessive dosage, improper mixing, and abnormally bad environmental conditions will cause phytotoxicity to crops. Herbicide phytotoxicity leads to abnormal growth of crops, twisted stems and leaves, clumps, dwarfed plants, flowers but not fruit, and even dead seedlings and reduced yield. The herbicide's phytotoxicity is light and the yield is reduced by 10...
