Description

Weeding composition containing condensed ring substituted aromatic compound and application thereof
Technical Field
The invention belongs to the field of pesticides, and particularly relates to a weeding composition containing condensed ring substituted aromatic compounds and application thereof.
Background
Chemical weeding is the most economical and effective means in farmland weed control, but long-term continuous high-dosage chemical herbicide with single variety or single action mode is easy to cause problems of weed resistance, resistance evolution and the like. The reasonable compounding or compounding of the herbicide compound has the advantages of expanding the weed spectrum, improving the preventing and killing effect, delaying the occurrence and development of weed resistance and drug resistance, and the like, and is one of the most effective methods for solving the problems. As disclosed in patent CN 113402510A, a condensed ring substituted aromatic compound and its use as herbicideThe herbicide composition variety which has high safety, wide herbicide spectrum, can produce synergistic effect and solve the problem of resistant weeds is still required to be developed in production.

Preferably, the active ingredient A is A1
The weight ratio of A, B in the weeding composition is 1:200-50:1, 1:180-30:1, 1:160-25:1, 1:150-20:1, 1:120-18:1, 1:100-15:1, 1:80-12:1, 1:50-10:1, 1:40-8:1, 1:30-6:1, 1:20-5:1, 1:15-3:1, 1:12-1:1, 1:10-1:3 or 1:8-1:5.
The mass percentage of A, B in the weeding composition accounts for 1-95%, preferably 10-80% of the total mass.
The herbicidal composition further comprises conventional adjuvants including carriers and/or surfactants.
The term "carrier" as used herein means an organic or inorganic, natural or synthetic substance. They facilitate the application of the active ingredient, which carriers are generally inert and must be agriculturally acceptable, in particular by the treated plants. The carrier may be solid, such as clay, natural or synthetic silicate, silica, resin, wax, solid fertilizer, etc.; or liquid, such as water, alcohols, ketones, petroleum fractions, aromatic or waxy hydrocarbons, chlorinated hydrocarbons, liquefied gases, and the like.
Surfactants may include emulsifiers, dispersants or wetting agents, which may be ionic or nonionic. Examples which may be mentioned are salts of polyacrylic acid, lignosulfonates, salts of phenolsulfonic acid or naphthalenesulfonic acid, polymers of ethylene oxide with aliphatic alcohols or with aliphatic amines with substituted phenols, in particular alkylphenols or arylphenols, sulfosuccinates, taurine derivatives, in particular taurates, and phosphates of alcohols or of polyethylated phenols, alkylsulfonates, alkylaryl sulfonates, alkyl sulfates, lauryl ether sulfates, fatty alcohol sulfates, and also sulfated hexadecyl-, heptadeca-and octadecanols and sulfated fatty alcohol glycol ethers, furthermore condensates of naphthalene or naphthalenesulfonic acid with phenol and formaldehyde, polyoxyethylene octylphenyl ether, ethoxylated isooctylphenols, octylphenols or nonylphenols, alkylphenyl polyglycol ethers, tributylphenyl polyglycol ethers, tristearylphenyl polyglycol ethers, alkylaryl polyether alcohols, alcohol and fatty alcohol/ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers, ethoxylated polyoxypropylene, lauryl alcohol polyglycol ethers, sorbitol esters, lignin sulfite waste solutions, and also proteins, polysaccharides (e.g. methylcellulose), polyvinyl alcohol, hydrophobically modified polyvinyl pyrrolidone, polyvinyl alcohol carboxylate, polyvinyl pyrrolidone, and copolymers thereof. At least one surfactant is required to be present to facilitate the dispersion of the active ingredients in water and to enable them to be applied correctly to the plants.

Each treatment was repeated 4 times, 3 pots each time, each pot was sown with 30 weed seeds.
2) Test method
Irrigation was carried out before treatment, and a 1-2cm aqueous layer was maintained. Taking quantitative liquid medicine by a liquid shifter, and respectively irrigating from low dose to high dose according to test design, wherein each treatment is repeated for 4 times; after treatment, the cells were transferred to a greenhouse for routine cultivation, and a 1-2cm aqueous layer was maintained throughout the test period.
3) Data investigation and statistical analysis
The spraying treatment is the same as that of the stem and leaf after seedling, so the description is omitted.
The statistical results are shown in tables 1-30 below, and the other results are "post-seedling stem and leaf spray treatment" except for the clear mark "soil treatment".
