Abstract
The invention relates to a weeding composition. The weeding composition is composed of three active ingredients including glufosinate-ammonium, oxyfluorfen and topramezone, auxiliary agents and an excipient, wherein the weight percent ratio of glufosinate-ammonium to oxyfluorfen ranges from 1:3 to 3:1; the weight ratio of glufosinate-ammonium or oxyfluorfen to topramezone ranges from 5:1 to 1:5; the weight of glufosinate-ammonium, oxyfluorfen and topramezone accounts for 10%-90% of the total weight of the weeding composition. The weeding composition is applicable to soil of undesired vegetations and stems and leaves of the undesired vegetations, or grass burning carried out before crops are planted or before emergence of seedlings of sowed seeds and post-treatment of seedlings of tolerance crops and non-tolerance crops. According to the weeding composition, the high synergistic interaction effect can be achieved, the generation of weed drug resistance is overcome or delayed, the herbicide controlling spectrum is expanded, the pesticide utilization cost is reduced and the toxicity is lowered.
Description
Technical field
The present invention relates to a kind of Herbicidal combinations.
Background technology
Along with the variation of cropping system and the demand of economic crops promote, particularly in the long-term use procedure of agricultural chemicals, the resistance of having made deposits yields, reduces its drug effect greatly.Meanwhile, make crop is the problem frequently recurring away from the protection of not wishing vegetation that suppresses plant growth in agricultural.In order to help to address this problem, the researcher in synthetic chemistry field has produced described in controlling and has not wished that the growth of vegetation is effective multi-chemical and chemicals.Permitted eurypalynous chemical herbicide and disclosed in the literature, and multiple for commercial use.
In some cases, more effective when while having shown herbicidal active component combined administration, ratio is used separately, this is called " synergy "." synergy " is the interaction of two or more factors, thereby the effect while combination is greater than corresponding prediction effect while application separately based on each factor.The present invention is based on this type of discovery: when the known careless ammonium phosphine separately with weeding effect, Oxyfluorfen and benzene azoles humulone applied in any combination, demonstrate synergy.
Grass ammonium phosphine (Glufosinate-ammonium) chemical name is 4-[hydroxyl (methyl) phosphono]-DL-high lactamine; it is to succeed in developing (belonging to afterwards Beyer Co., Ltd) eighties by Hirst company; belong to that phosphinic acids classes is efficient, low toxicity, the environment amenable non-conducting natural disposition broad-spectrum touch-out type weed killer herbicide that goes out; systemic action is not strong; to kill root different from glyphosate; grass ammonium phosphine first kills leaf; can conduct at plant xylem by plant transpiration effect, between its quick-acting between paraquat and glyphosate.In soil, be easy to degraded, to crop safety, be difficult for drift, herbicidal spectrum is wide, and active high, consumption is few, and environmental pressure is little, is world's large-tonnage pesticide species.The particularly fast development of transgenic technology at present, the plantation of transgenosis herbicide-resistant crop is the gesture growing in intensity in recent years, and herbicide-tolerant uses significantly to be increased.Grass ammonium phosphine is an outstanding steriland herbicide, be applicable to very much doing resistant gene, the resistance to careless ammonium phosphine crop of commercialization plantation has almost comprised all chief crops, these genetically modified crops are generally planted at north America regions such as the U.S., as anti-careless ammonium phosphine kind in Canada's calendar year 2001 4000000 hectares of rapes reaches 13%.In recent years in Asia, Australia, Some European country and regional popularizing planting, this makes careless ammonium phosphine, and oneself becomes current second-biggest-in-the-world genetically modified crops herbicide-tolerant, therefore the market prospects of this product are very wide.
Oxyfluorfen (Oxyfluorfen) chemical name is the chloro-4-trifluoromethyl-3'-of 2-ethyoxyl-4'-nitrobenzophenone ether, it is the fluorine-containing benzene ether-derivative herbicides of being succeeded in developing by Rhom and Hass of the U.S. for 1975, its activity of weeding improves 5 ~ 10 times than corresponding nitrofen, is 16.32 times of benthiocarb.The scope of application is wide, broad weed-killing spectrum, and the lasting period is long, and mu consumption is few, active high, can use with multiple mixture of herbicides, expands herbicide spectrum, improves drug effect, easy to use, both can bud pre-treatment, again can bud post processing, toxicity is low.For contact killing type weed killer herbicide.In the situation that having light, bring into play its activity of weeding.Mainly enter in plant corpus by coleoptile, mesocotyl, less through root absorption, and have denier upwards to transport by root the leaf portion that enters.
Benzene azoles humulone (Topramezone) chemical name is [3-(4; 5-dihydro-1; 2-oxazole-3-yl)-4-formoxyl 0-tolyl] (5-hydroxyl-1-methyl-pyrazol-4-yl) ketone; developed by German BASF; after a kind of novel pyrazole quinoline ketone seedling, cauline leaf is processed inner-adsorption conduction-type herbicide, and active ingredient is benzene azoles humulone.This weed killer herbicide can effectively be prevented and kill off corn field annual gramineous weed and broad leaved weed.The weeds that can effectively prevent and kill off have: lady's-grass, barnyard grass, eleusine indica, wild broomcorn millet, green foxtail, lamb's-quarters, knotweed, piemarker, kitchen garden, Siberian cocklebur, black nightshade etc.Except above-mentioned weeds are had excellent preventive effect, can also there is good preventive effect as field thistle (field thistle), corn sow thistle, acalypha copperleaf, dayflower (orchid dish) to pernicious broad leaved weed.Absorbed by the blade of weeds, root and stem, and in plant corpus Bidirectional Conduction up and down, remote-effects carotenoid synthetic, disturbs chloroplast synthetic and function under illumination, finally causes the serious albefaction of weeds, necrosis, weeds death.
At present, also do not have about by the report of careless ammonium phosphine, Oxyfluorfen, benzene azoles humulone applied in any combination.
Summary of the invention
