Description
Technical field
The present invention relates to technical field of pesticide combination, particularly relate to a kind of Herbicidal combinations containing benzene flumetsulam, glyphosate and Quizalotop-ethyl.
Background technology
Benzene flumetsulam is the uracil weeding agent of being developed by BASF AG.Its chemistry N-[the fluoro-5-of the chloro-4-of 2-(3-methyl-2 by name, 6-diketone-4-(trifluoromethyl)-3,6-dihydro-1 (2H) pyrimidine radicals) phenyl]-N-isopropyl-N-Methanesulfomide, can be used as steriland herbicide to use, can effectively prevent and kill off multiple broad leaved weed, comprise glyphosate, ALS and triazines produce the weeds of resistance.Have and very fast go out raw effect and pedo relict degraded rapidly.May be used for control wheat paddock broad leaved weed.
Glyphosate mainly hinders the biosynthesis of ArAA, and namely phenyl alanine, tryptophan and tyrosine are by the synthesis of shikimic acid pathway.It has inhibitory action to 5-enol pyruvylshikimate-3-phosphate synthase (EPSP synthase), this enzyme can catalysis shikimic acid-3-phosphoric acid and enolpyruvyl phosphoric acid to the conversion of 5-enol pyruvylshikimate-3-phosphoric acid (EPSP), therefore glyphosate disturbs this biosynthetic enzymatic reaction, causes shikimic acid accumulation in vivo.In addition glyphosate also can suppress the activity of other plant enzyme and animal ferment.The metabolism of glyphosate in higher plant is very slow, and once testing out its metabolite is AminomethylphosphoniAcid Acid and methylamino acetic acid.Just because glyphosate has behavior in service, the slowly degradation property of height and the phytotoxicity of height in plant corpus, determining it is being a desirable weed killer herbicide preventing and kill off perennial weed.
Quizalotop-ethyl is a kind of benzene oxygen herbicide of aliphatic acid, selectivity inner sucting conduction type cauline leaf inorganic agent.Medicament has high selectivity between grassy weed and dicotyledonous crops, and cauline leaf can complete the absorption to medicament in several hours, and annual weed can spread all over complete stool in 24h.Prevent and kill off monocotyledon weed with being applicable to cotton, soybean, rape, peanut, flax, apple, grape, beet and multiple wide leaf vegetable crop.During increasing dose, also there is effect to perennial weeds such as Bermuda grass, cogongrass, reeds.
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 benzene flumetsulam, glyphosate and Quizalotop-ethyl composite, have obvious synergistic effect.And about the composite Herbicidal combinations of benzene flumetsulam, glyphosate and Quizalotop-ethyl and apply and there is no people at present and reported.
Summary of the invention
