Efficient and low-toxicity herbicide used for garden

Abstract

The invention discloses an efficient and low-toxicity herbicide used for a garden. The herbicide is prepared from the following raw materials in parts by weight: 1-2 parts of oxyfluorfen missible oil,14-18 parts of butachlor, 10-12 parts of acetochlor, 15-40 parts of triethanolamine, 4-8 parts of carfentrazone, 5-10 parts of clodinafop-propargyl, 10-20 parts of flumiclorac-pentyl missible oil, 12-15 parts of fomesafen, 8-15 parts of cloransulam-methyl, 5-10 parts of organosilicone, 20-35 parts of fenoxaprop-p-ethyl, 5-10 parts of glyphosate, 0.3-0.5 part of gibberellin, 0.1-0.2 part of indoleacetic acid, 10-12 parts of triacontanol, 2-4 parts of urea, 10-20 parts of carbetamide, 5-10 parts of clopyralid, 10-13 parts of mesotrione, 5-7 parts of bentazone, 6-8 parts of bensulfuron methyl, 10-12 parts of glufosinate-ammonium, 12-15 parts of glyphosate, 20-25 parts of water soluble salt and 100-150 parts of deionized water. All raw materials can be compounded to achieve purposes of complementing advantages, reducing a use amount, controlling effects and enhancing. The efficient and low-toxicity herbicide has the advantages of high effect taking speed, wide weed control spectrum, longlasting period, thorough weed removal, low residue, low toxicity, safety, environment protection and the like.

Description

Technical field [0001] The invention relates to a high-efficiency and low-toxic garden herbicide, which belongs to the technical field of pesticides. Background technique [0002] Weeds grow rapidly, not only competing with flower seedlings for nutrients and water, but also serving as intermediate hosts for a variety of pests and diseases. If not controlled in time, they will spread and affect the growth of flowers and trees. [0003] Herbicides are chemicals that can completely or selectively kill weeds and are used to eliminate or inhibit plant growth. Among them, sodium chlorate, borax, arsenate, and trichloroacetic acid have the effect of killing any kind of plants. Their effects are affected by three factors: herbicides, plants, and environmental conditions. According to their effects, they are divided into biocidal and selective herbicides. Most of the selective herbicides, especially derivatives of nitrophenol, chlorophenol and carbamate, are effective. [0004] Her...

AI Technical Summary

Problems solved by technology

[0004] Herbicides have become an important means of weeding in farmland to reduce labor intensity and improve work efficiency. At present, chemical herbicides occupy most of the market, but with the continuous application of chemical herbicides, their disadvantages have been clearly exposed. The first is the drift of herbicide droplets , liquid volatilization, unsatisfactory selectivity, and the hazards of degradation products cause phytotoxicity of crops; followed by repeated use of herbicides resulting in the increase of drug-resistant weed populations, the emergence of herbicide-resistant weeds and the increasingly serious environmental pollution , making it increasingly difficult and expensive to develop new herbicides

Although the use of chemical herbicides has effectively controlled many weeds in the past century, the extensive use of chemical agents has also caused a series of problems, such as the emergence of herbicide-resistant weed plants, soil pollution, water quality degradation, and the The harm of non-weed organisms, etc. Some fields that have used long-term herbicides for a long time also have accumulated herbicide residues, which seriously affects the growth of subsequent crops, forming the phenomenon of "cancer fields"

Moreover, the harmful pesticides have also changed the soil, made the soil alkalized, polluted the environment, caused a serious biological imbalance, and caused many small animals and birds to become extinct. The residual harmful substances also seriously affect human health. Physical health and the reproduction of species in the world
