Description
Technical Field
The invention relates to a pesticide active herbicide composition, in particular to a herbicide composition containing regulatory phosphine and application thereof in controlling harmful plants.
Background
The agricultural chemical is an important agricultural production data and is important for preventing diseases and controlling insects, and promoting stable and high yield of grains and agriculture. However, the pesticide usage amount is large, and the application method is not scientific enough, so that the problems of increased production cost, exceeding of agricultural product residues, crop phytotoxicity, environmental pollution and the like are caused. In order to promote the transformation of agricultural development modes, the pesticide usage amount is effectively controlled, the agricultural production safety, the agricultural product quality safety and the ecological environment safety are ensured, and the agricultural sustainable development is promoted.
Part of plant growth regulator can inhibit weed growth at high concentration, and has herbicidal effect. The plant growth regulator and the weeding compound are reasonably screened and compounded, and the weeding compound has the characteristics of reducing the using amount of the weeding compound, expanding the weeding spectrum, safety and high efficiency. Is an effective measure for dealing with zero increase of pesticide usage.
The phosphine is regulated, and the phosphine is mainly applied to flower preservation, chemical pruning of fruit trees and woody plants, dwarfing of shrubs, growth inhibition and the like. Can also be used as a control agent for shrubs and certain dicotyledonous weeds. At present, the pesticide is widely used for poisoning the hybrid shrubs of non-cultivated lands and preventing and killing the perennial broadleaf weeds in pastures.
Glyphosate, english generic name glyphosate, CA accession number: 1071-83-6, chemical name N- (methyl phosphate) glycine. Molecular formula C 3H8NO5 P, molecular weight 169.09; is systemic conduction type chronic broad-spectrum biocidal herbicide, and is used to inhibit the in vivo enolpyruvylshikimin phosphate synthase, so as to inhibit the conversion of shikimin into phenylalanine, tyrosine and tryptophan, and interfere the synthesis of protein to cause death of plant. Glyphosate is absorbed by the stems and leaves and then transmitted to all parts of plants, and can prevent and kill monocotyledonous and dicotyledonous plants, annual and perennial plants, herbs, shrubs and other plants of more than 40 families, and has poor sensitivity to partial weeds. After the glyphosate is put into soil, the glyphosate is combined with metal ions such as iron, aluminum and the like to lose activity, and has no adverse effect on hidden seeds and soil microorganisms in the soil, and because the glyphosate has no selectivity, the glyphosate is widely used for weeding in non-farmland, orchards, roads, forestry and the like, and the application range of the glyphosate is gradually over-large in recent years.
Glufosinate, english generic name Glufosinate ammonium, CA accession number: 77182-82-2, ammonium 2-amino-4- [ hydroxy (methyl) phosphono ] butanoate. Molecular formula C 5H15N2O4 P, molecular weight 198.16; belongs to organophosphorus herbicides, is a glutamine synthesis inhibitor, is a nonselective contact herbicide, and is also a herbicide for the second largest transgenic crop in the world. Compared with glyphosate, the herbicide has the advantages of broad herbicide spectrum, quick degradation in soil, low toxicity, environmental friendliness and the like, is a further excellent-performance biocidal herbicide variety after glyphosate, and is only registered for preventing and killing weeds in orchards and non-cultivated lands at present. Along with the banning of paraquat at home and abroad, glufosinate is taken as a representative of contact herbicide, and the market share is necessarily larger and larger. The ammonium glyphosate aqueous adjuvant which is accepted at home and abroad at present mainly comprises AES, alkyl glycoside, alkyl polyether and other compounds.
Smart glufosinate, international generic name: glufosinate-P, CA accession number: 35597-44-5, chemical name: (2S) -2-amino-4- [ hydroxy (methyl) phosphinyl ] butanoic acid. Molecular formula C5H12NO4P, molecular weight: 181.23; the action mechanism is glutamine synthetase inhibitor, which causes ammonium ion accumulation in plants to inhibit photosynthesis and achieve weeding effect. The glufosinate-ammonium has low toxicity and is safer, easy to degrade in soil, safe to crops, small in drift and safe to adjacent crops; has wide weeding spectrum (effective on various annual and perennial weeds), can treat malignant weeds with resistance to glyphosate, has high activity, and has rapid weeding (between glyphosate and paraquat) and long lasting period. The contact killing weeding is mainly performed, the weeding cannot be transferred to other places, and the weeding is safe for aftercrop; the pesticide has very good water solubility, stable structure, convenient processing and mixing use, low environmental pollution and higher refinement of the pesticide; the application range is wide, and the weeding composition can be used for preventing and killing various annual and perennial broadleaf weeds and grassy weeds in orchards, vineyards, rubber gardens, uncultivated lands and other lands.
Topramezone, english generic name topramezone, CA accession number: 210631-68-8, chemical name: [3- (4, 5-dihydro-1, 2-oxazol-3-yl) -4-methylsulfonyl-2-methylphenyl ] (5-hydroxy-1-methylpyrazol-4-yl) methanone, formula: c 16H17N3O5 S, molecular weight: 363.43. the herbicide belongs to a trione post-seedling stem leaf treatment herbicide, is absorbed by roots, seedlings and leaves, is transmitted to meristems from the top and the base in plants, inhibits 4-HPPD, inhibits biosynthesis of carotenoid and chlorophyll and has disturbed functions, so that sensitive weeds which germinate are bleached within 2-5 days of treatment, and the plants die within 14 days. BAS670 011 is selectively based on low sensitivity to herbicide target enzymes, slow absorption, slow conduction, rapid metabolism to inactive species. The weeding composition has high activity, extremely low dosage, wide and flexible application period after seedling, wide weeding spectrum, and can effectively prevent and remove annual gramineous weeds and broadleaf weeds in corn fields, and has a certain inhibition effect on weeds such as nutgrass flatsedge.
Azosulfuron, english generic name orthosulfamuron, CA accession number: 213464-77-8, chemical name: 1- (4, 6-dimethoxypyrimidin-2-yl) -3- [2- (dimethylcarbamoyl) benzenesulfonyl ] urea of formula: c 16H20N6O6 S, molecular weight: 424.43; the sulfonylurea herbicide can inhibit synthesis of plant branched chain amino acid by inhibiting Acetolactate Synthase (ALs) of weeds, so as to inhibit synthesis of weed protein, stop cell division of weeds and kill weeds. The pyriminomethyl can be absorbed by the leaves and roots of weeds, and can prevent and remove barnyard grass, nutgrass flatsedge, broadleaf weeds, duckweed moss and the like.
At present, no weeding composition consisting of phosphine, glyphosate, glufosinate, metamifop, topramezone and azosulfuron is reported.

TABLE 10 determination of Amaranthaceae and Eleusines (Gowing method) by combining toxicity of the mixture of azosulfuron and adjusting phosphine
The theoretical survival rate E 0 value, the actual survival rate E value and the difference between the actual value and the theoretical value (E-E 0) of each mixed combination are calculated by a Gowing method. The results show that for amaranth, the survival rate measured values of each combination of F and A are greater than the theoretical value, the difference is between 8.9 and 12.2, wherein the E-E 0 value is the largest when F low dose (60 g a.i./hm 2) and A medium dose (1400 g a.i./hm 2) are mixed, and the synergistic effect is the most obvious. For the common goosegrass, the actual measurement value of the survival rate of each combination of F and A is larger than the theoretical value, the difference value is between 8.1 and 12.4, wherein the E-E 0 value is the largest when F low dose (60 g a.i./hm 2) and A medium dose (1400 g a.i./hm 2) are mixed, the synergistic effect is the most obvious. For the ageratum conyzoides, the actual measured value of the survival rate of each combination of F and A is larger than the theoretical value, the difference is between 8.4 and 12.7, wherein the E-E 0 value is the largest when F low dose (60 g a.i./hm 2) and A medium dose (1400 g a.i./hm 2) are mixed, the maximum synergistic effect is reached to 12.7. For nutgrass galingale rhizome, the actual measurement value of the survival rate of each combination of F and A is larger than the theoretical value, the difference value is between 8.3 and 11.7, wherein the E-E 0 value is maximum when F low dose (60 g a.i./hm 2) and A medium dose (1400 g a.i./hm 2) are mixed, the maximum synergistic effect is reached to 11.7. (see tables 9, 10).
Test results: as can be seen from the indoor biological measurement results in tables 1 to 10, the glyphosate, glufosinate-ammonium, topramezone and azosulfuron are respectively combined with the adjusting phosphine to be used, so that the weeding composition has good synergistic effect and additive effect, and the actual prevention effect on weeds is better than that of single agents, and the optimal scheme is as follows: glyphosate (B): regulatory phosphine (a) =2400+800 (3+1), glufosinate (C): adjusting phosphine (a) =1800+1400 (9+7), arginate (D): adjusting phosphine (a) =540+2000 (27+100), topramezone (E): adjusting phosphine (a) =35+2000 (7+400), azosulfuron (F) +adjusting phosphine (a) =60+1400 (3+70).
