Abstract
The invention discloses a herbicide composition containing glyphosate, MCPA (2-methyl-4-chloro-phenoxyacetic acid) and carfentrazone-ethyl. The herbicide composition is characterized in that the pesticide active ingredients of the composition are glyphosate or salts thereof, MCPA or salts or esters thereof and carfentrazone-ethyl; based on the herbicide composition, the weight percent of the pesticide active ingredients is 31.1-85%, wherein the weight percent of the glyphosate or salts thereof is 30-70%, the weight percent of the MCPA or salts or esters thereof is 1-30%, the weight percent of the carfentrazone-ethyl is 0.1-20% and the balance is non-pesticide ingredients. The dosage forms of the herbicide composition are wettable powder, water dispersible granules, soluble powder, soluble granules, aqueous solutions, emulsion in water and microemulsion. The composition has the advantages that after compounding, the herbicide composition has obvious synergistic effects, expands the weed control spectrum, increases the weed control speed, obviously reduces the usage amount and numbers of use of herbicides and can be applied to controlling imperata cylindrica, Bidens pilosa, dicranopteris dichotoma, eleusine indica, erigeron canadensis and other weeds in arable lands and non-arable lands.
Description
Technical field
The invention belongs to agricultural herbicide technical field, relate to particularly a kind of herbicidal composition, particularly take the herbicidal composition that glyphosate or its salt, 2 first 4 chlorine or its salt or its ester and azoles humulone be active ingredient, this herbicidal composition can be applied to prevent and treat the weeds such as cogongrass Imperata cylindrica, bidens pilosa Bidens pilosa, iron awn winnow basket Dicranopteris dichotoma, eleusine indica Eleusine indica, Horseweed Herb Erigeron canadensis.

The weed killer herbicide that Chinese patent discloses some glyphosates, 2 first 4 chlorine or azoles humulone and become with other compound combination, for example: 200910063612.4, gram Weeding water agent of making without track and 2 first 4 chlorine sodium binary builts and preparation method thereof; 201110327315.3, a kind of Herbicidal combinations containing ethoxysulfuron and 2 first 4 chlorine sodium; 201310083527.0, a kind of oil-suspending agent that dispersibles containing florasulam and the different monooctyl ester of 2 first 4 chlorine; 201010605083.9, a kind of herbicidal composition containing benzene azoles humulone, fluthiacet and 2 first 4 chlorine sodium; 201110394725.X, a kind of Wheat field weeding composition and preparation thereof; 201210318528.4, a kind of Herbicidal combinations containing hexazinone and phenoxy carboxylic acid; 200910034319.5,200910034319.5, azoles humulone cyhalofop-butyl dichloro quinolinic acid complex weedicide; 201110157619.X, a kind of Herbicidal combinations containing azoles humulone and Brominal; 201110158872.7, a kind of Herbicidal combinations containing azoles humulone and Flumetsulam; 201110160825.6, a kind of Herbicidal combinations containing azoles humulone; 200810173590.2, a kind of combinations of herbicides; 200910243683.2, herbicidal composition; 200910222125.8, effectiveness-enhanced glyphosate weeding combination etc.Shown that the weed killer herbicide that glyphosate, 2 first 4 chlorine or azoles humulone and they become with other compound combination has good herbicide effect and is applied in agricultural.In the prior art, patent documentation CN101784194A discloses glyphosate and the composite Herbicidal combinations of MCPA, although also mentioned when using together with other weed killer herbicide, can be by described composition and other one or more weed killer herbicide preparations, and enumerate out hundreds of kind weed killer herbicide, but it also reckons without compatibility after composite and the antagonism of appearance, and its synergy, expand the DeGrain of herbicide spectrum, herbicidal effect needs further to be improved.In addition, patent documentation CN102657218A discloses 2 first 4 chlorine isopropyl amine salts and the composite composition of glyphosate isopropyl amine salt, and it is complementary mentioning the two, but itself and not mentioned the two and azoles humulone is composite, also and reckon without the mixed ratio etc. of the antagonism of compatibility, synergy mixed ratio and appearance after ternary built.Patent documentation CN102771508A discloses the combination of glyphosate isopropyl amine salt, 2 first 4 chlorine sodium salts and fluroxypyr, and equally also not mentioned azoles humulone is composite.In sum, with research and the application of glyphosate, 2 first 4 chlorine and these 3 kinds of mixture of herbicides of azoles humulone, have no open source literature report at present.
Cogongrass, bidens pilosa, iron awn winnow basket, eleusine indica, Horseweed Herb etc. are weeds common in various crop field, forest land and uncultivated area, use separately glyphosate, 2 first 4 chlorine or azoles humulone effectively not to prevent and kill off these weeds, want to obtain desirable preventive effect and can only strengthen formulation rate simultaneously.Yet by strengthen dosage reach preventive effect will certainly increase the weight of weed killer herbicide residual, cause the poisoning of crop increased to cost accounting simultaneously.And, use separately in actual applications the weeding speed of glyphosate slow, and be subject to the impact of the bad climates such as low temperature, rainfall and limited the performance of drug effect.In addition, use for a long time single weed killer herbicide to tend to cause the generation of herbicide resistance, and then reduce the preventive effect of weed killer herbicide.
Different weed killer herbicides carries out the composite herbicide that can expand and composes, and adopt the mixture of herbicides that the mode of action is different and demonstrate synergistic effect, be mixture to the inhibitory action of weed growth the desired value higher than each component independent role in mixture, make weeds be difficult to eliminate the impact of different weed killer herbicides on its metabolic pathway, and then delay the generation of herbicide resistance, being the target of exploitation mixture of herbicides preparation, is also to alleviate environmental pollution, reduces the effective means of herbicide residue.We are through screening, discovery is by glyphosate, 2 first 4 chlorine and azoles humulone is composite can realize above-mentioned advantage, herbicide combination product containing mentioned component also has broad weed-killing spectrum, the fireballing feature of herbicide, thereby there is the advantages such as impact that drug effect is not subject to the bad climates such as low temperature, rainfall, be the fine herbicide of the weeds chemical controls such as cogongrass, bidens pilosa, iron awn winnow basket, eleusine indica, Horseweed Herb.
Summary of the invention
The invention provides a kind of glyphosate, 2 first 4 chlorine and the composite weed killer herbicide of azoles humulone, between this weed killer herbicide active ingredient, there is synergistic function, can also widen herbicide spectrum, improve herbicide speed, form efficient a, wide spectrum, weed killer herbicide kind that use cost is low.This weed killer herbicide not only can be prevented and kill off all weeds that glyphosate, 2 first 4 chlorine and azoles humulone single dose can be prevented and kill off, the weeds such as cogongrass that independent use glyphosate, 2 first 4 chlorine or azoles humulone can not finely prevent and kill off, bidens pilosa, iron awn winnow basket, eleusine indica, Horseweed Herb be can also prevent and kill off, forest land, the disposable chemical weed control of uncultivated area realized.
