Description
Technical field
The present invention relates to technical field of pesticide combination, particularly relate to a kind of Herbicidal combinations containing tribenuron-methyl, mesosulfuron and clodinafop-propargyl.
Background technology
Tribenuron-methyl is a kind of selectivity inner-adsorption conduction-type herbicide; be mainly used in preventing and kill off various annual broadleaf weed; better to the effect such as Descurainia sophia, shepherd's purse, shepherd's purse of cracking rice, corn gromwell, lamb's-quarters, Amaranthus retroflexus; also certain preventive effect is had to summer cypress, chickweed, knotweed, clearvers etc.; the chemistry of tribenuron-methyl is called 2-[N-(4-methoxyl group-6-methyl isophthalic acid; 3,5-triazine-2-base)-N-methylcarbamoyl amido sulfonyl] methyl benzoate, its chemical structural formula is.
Mesosulfuron is sulfonylurea herbicide; cauline leaf mainly through plant absorbs; through phloem and xylem conduction, on a small quantity by soil absorption, suppress the activity of the acetolactate synthestase in sensitive plant body; cause the biosynthesis block of the numerous acid of side chain ammonia; thus T suppression cell division, cause the safener contained in sensitive plant death, can promote that it is doing to decompose rapidly in object; and do not affect its degraded in target weeds body, thus reach the object of killing weeds, cover crop.Mesosulfuron is applicable to use in soft and semi-rigid type winter wheat variety.Amur foxtail, wild oat, caput grass, annual bluegrass, hard grass, alkali thatch, Annual Ryegrass, lolium temulentum, bromegrass, candle grass, Triticum tauschii, Tong grass, wheatgrass, shepherd's purse, Descurainia sophia, ox chickweed, spontaneous rape etc. can be prevented and kill off.
Clodinafop-propargyl ((R)-2-[4-(the chloro-3-of 5-fluoro-2-pyridine oxygen base) phenoxy group] propionic acid propargyl ester) is a kind of new herbicides.Its design feature has chirality, fluorine-containing with arylphenoxy phenoxy propionic acid.It is little that it shows as toxicity in performance; Consumption is few; Drug effect is high; Metabolic capability is strong; The growth of multiple weed seed can be suppressed.
Composite or the mixture of rational chemical herbicide has expansion herbicidal spectrum, improve control efficiency, extend the optimum period for applying fertilizer, reduce dosage, reduce poisoning, minimizing remains, delay the actively feature such as drug-fast generation and development, mixture of herbicides or mixture are one of the effective methods the most solved the problem.We, on the basis of lab screening and field trial, filter out tribenuron-methyl, mesosulfuron and clodinafop-propargyl composite, have obvious synergistic effect.And about the composite Herbicidal combinations of tribenuron-methyl, mesosulfuron and clodinafop-propargyl and apply and there is no people at present and reported.
