Description
Technical field
The present invention relates to a kind of compound herbicide composition, particularly relate to a kind of binary built, be applied to the compound herbicide composition in crops field.
Background technology
In plant husbandry, preventing and treating suppression plant growth to cause weeds that yield reduces and cover crop be critically important.Have now been developed some can effectively controlling weeds and the herbicidal active component to crop safety, greatly reduce the loss caused in arable farming by weeds.High activity of weeding and wide herbicidal spectrum is not only needed for preventing and treating the herbicide of the weeds in specific arable farming, and will be to environment and crop safe enough.But, not every herbicide can fully meet above-mentioned requirements.
The most common method of the herbicidal spectrum increasing activity of weeding and widen existing herbicide is that two or more have the herbicidal active compounds mixing of different activity of weeding.When the effect of the mixture of two or more active component is more than the expection effort levels of each active component, we term it " potentiation ".Therefore mixing two or more herbicidal active component, may demonstrate the herbicide action outstanding than single herbicide application.But, present in the described Herbicidal mixture formed from two or more herbicidal active component, potentiation is the most in limited instances.Due to the difference of the aspects such as herbicidal performance, absorbance, transfer, metabolism, the herbicide action that the activity of weeding of most of mixture is administered alone less than each active component, i.e. demonstrate " antagonism ".If the herbicide action of the mixture of two or more herbicidal active component is identical with singly executing of each active component, i.e. demonstrate " addition ".
Benzene flumetsulam (Saflufenacil); No. CAS is 372137-35-4; chemical name is: N'-[the fluoro-5-of the chloro-4-of 2-(1; 2; 3; 6-tetrahydrochysene-3-methyl-2,6-dioxy-4-trifluoromethyl pyrimidine-1-base) benzoyl]-N-isopropyl-N-methylsulfonamides, its chemical formula is:
Benzene flumetsulam is the one developed by BASF AG up-to-date benzazole dione herbicides, represents the new height that broad leaved weed is prevented and kill off.Benzene flumetsulam is disclosed in WO01/083459.Benzene flumetsulam is applicable to multiple planting system and bare place, uses and prevent and kill off broadleaf weed before Different Crop Seedling or after Seedling.Benzene flumetsulam is a kind of effective proporphyrinogen oxidase inhibitor (PPO).Proporphyrinogen oxidase is necessary to plant chlorophyll biosynthesis.The repressed result of proporphyrinogen oxidase is to destroy cell membrane, causes cell seepage, tissue necrosis, and final plant is dead.Benzene flumetsulam is easily absorbed by root, bud and blade.Once being absorbed, benzene flumetsulam is mainly upwards transmitted to each position of weeds by xylem.
Bensulfuron-methyl (Bensulfuron-methyl), has another name called Nongdeshi (Londax), and chemical name 2-{ ((4,6-dimethoxypyridin-2-base) amino carbonyl amino] sulfonvlmethvl) its structural formula of essence of Niobe is:
Bensulfuron-methyl is selectivity inner-adsorption conduction-type herbicide.Medicament spreads rapidly in water, transfers to other position, hinder branched-chain amino acid biosynthesis after weeds root and blade absorb.Susceptible weeds GF is obstructed, tender tissue turns to be yellow too early, suppresses leaf portion, root growth.Bensulfuron-methyl can effectively prevent and treat the annual and perennial broad leaved weed in rice field and dried tuber.After crop bud, before weeds bud and dispenser after bud, respond well to Herba monochoriae vaginalis, Herba potamogetonis distincti, mexicana etc. and sedge weed (fescue, Herba Cyperi Difformis, Herba Cyperi Glomerati etc.).
The preventing and treating of agricultural weed always agricultural production is concerned about and important problem the most.The whole Growing season of crop nearly all can be endangered by various weeds.
