Abstract
The invention relates to a weeding compound. The weeding compound is prepared from the effective ingredients of diflufenican, terbuthylazine, pendimethalin, nicosulfuron, mesotrione and prometryn. The weeding compound disclosed by the invention has a synergistic effect on wheat paddock weeding, a single-dosage weed control spectrum is enlarged, the dosage of pesticide is reduced, the pesticide effect is rapidly expressed, the lasting period is long, the using cost is low, and the weeding compound is an ideal weed killer.
Description
Technical field
The invention belongs to technical field of pesticide, relate in particular to a kind of Herbicidal combinations containing diflufenican, Garagard, pendimethalin, nicosulfuron, mesotrione and prometryn.
Background technology
At present when weeds of wheat is prevented and kill off, the cauline leaf process weed killer herbicide controlling weeds such as conventional tribenuron-methyl, azoles humulone, florasulam.Tribenuron-methyl is applied for years, and make some areas wheat paddock broad leaved weed clearvers, Descurainia sophia, shepherd's purse etc. create obvious pesticide resistance to tribenuron-methyl, preventive effect worse and worse; Azoles humulone is poor to Safe to wheat, easily causes wheat leaf blade to produce contact killing type poisoning spot, and easily causes the poisoning underproduction; Florasulam is slow to the lethal speed of weeds, and the control efficiency such as broad leaved weed Descurainia sophia, shepherd's purse, clearvers developed immunity to drugs to tribenuron-methyl is also poor, and use cost is higher.
In order to overcome these shortcomings, in wheat field herbicide, people are by weed killer herbicide formation compound herbicides used in combination such as azoles humulone, florasulams, if application number is that CN201310083527 patent discloses a kind of florasulam and the composite compound herbicide of the different monooctyl ester of 2 first 4 chlorine, CN201310040708 patent discloses a kind of florasulam, fluroxypyr and the different monooctyl ester wheat field herbicide of 2 first 4 chlorine, application number be CN201310039795 patent discloses the composite wheat field herbicide of a kind of florasulam, bensulfuron-methyl.
Production practices prove, preventive effect is improve to a certain extent by composite, reduce cost, but preventive effect is still undesirable, still poor to preventive effects such as part pernicious broad leaved weed clearvers, chickweeds, after medicine, weeds easily turn green, particularly still poor to broad leaved weed preventive effects such as the clearvers developed immunity to drugs, Descurainia sophia, shepherd's purses.
Summary of the invention
The object of the present invention is to provide and a kind of there is synergistic effect, expand herbicide spectrum, reduce use cost particularly there to be the Wheat field weeding composition of fine preventive effect to the clearvers developed immunity to drugs, Descurainia sophia, shepherd's purse to pernicious broad leaved weed clearvers.
The technical scheme realizing the object of the invention is: Herbicidal combinations of the present invention is for active ingredient with diflufenican, Garagard, pendimethalin, nicosulfuron, mesotrione and prometryn, wherein containing diflufenican 8 ~ 10 parts, Garagard 6 ~ 9 parts, pendimethalin 5 ~ 8 parts, nicosulfuron 12 ~ 14 parts, mesotrione 3 ~ 5 parts, prometryn 9 ~ 12 parts, the total weight parts of six kinds of active ingredients accounts for 30 ~ 45% of whole pesticidal preparations gross weight, and all the other compositions are allow in agricultural chemicals to use and acceptable auxiliary element.
Described auxiliary element comprises wetting agent, dispersant, spreader-sticker, stabilizing agent, bleeding agent, thickener, antifreezing agent, defoamer, filler, solvent etc., be in pesticidal preparations the composition allowing to use, concrete composition and consumption are determined by test according to recipe requirements.
The composition pesticide formulation that described Herbicidal combinations is made by certain technical method can be wetting powder, suspending agent, missible oil, microemulsion, aqueous emulsion, granule and water dispersible granules.
The consumption of the present composition, with crops, the change of weeds situation and small variations, reaches the object of effectively preventing and treating by using appropriate dosage.
Herbicidal combinations of the present invention has synergistic function to weeds in wheat paddock, expand herbicide spectrum, early stage soil spray pesticide before seedling or after wheat seedling after Wheat Sowing, compound synergic is remarkable, reduce the using dosage of agricultural chemicals, drug effect plays rapidly, and the lasting period is long, use cost is low, has positive effect to the weeds of wheat comprehensive regulation.
Embodiment
Below in conjunction with specific embodiment, the present invention will be further described, but example does not limit the scope of the invention, in addition, any change that those of ordinary skill in the related art make the present invention, only otherwise depart from essence of the present invention, all equivalence is dropped in claims of the present invention limited range.
