Abstract
The invention provides a kind of barley field weeding composition and its application, belong to herbicide field, after selection active ingredient tralkoxydim and fluorine chloropyridine ester are compounded, can effectively control weeds, poisoning is reduced, it is particularly pertinent especially for the weeds herbicidal effect of barley field.The barley field weeding composition, including active ingredient and auxiliary element, active ingredient are fluorine chloropyridine ester and tralkoxydim, and the weight ratio of fluorine chloropyridine ester and tralkoxydim is 1:2‑32.Active ingredient fluorine chloropyridine ester and tralkoxydim weight percentage shared in the barley field weeding composition are 5% 95%, auxiliary element includes carrier and auxiliary agent, carrier is the one or more in water, solvent or filler, and auxiliary agent at least includes a kind of surfactant.
Description
Technical field
The present invention relates to pesticide field, more particularly to herbicide field, and in particular to a kind of barley field weeding composition and
It is applied.
Background technology
Widely distributed, the major production areas Relatively centralized of China barley, main distributed areas be the Yangtze river basin, the Huanghe valley and
Qinghai-Tibet Platean.In recent years, the development of brewing industry to increase sharply to the demand of raw material barley.
Herbicide is the conventional measure of current barley field control of weeds, to promoting barley production to improve and saving planting cost
With important effect.But herbicide it is long-term, promote the use of a large area, farmland weed chemical control trigger Weed Resistance,
Population succession and drug injury problem are on the rise, and have an impact to barley production and succession crop.Common use medicament is such as：Isopropyl
Grand, pinoxaden, Flumetsulam, florasulam, fenoxapropPethyl (big fat horse), tribenuron-methyl, azoles humulone, chlorine fluorine pyrrole oxygen
Acetic acid, the chlorine sodium of 2 first 4, bensulfuron-methyl etc..Barley field grassy weed is bad to prevent and kill off, it is necessary to based on early prevention and treatment, particularly field
Between grass it is mutually complicated, before seedling carries out closed soil treatment with class herbicide is closed preferably after broadcasting, weeds Seedling Stage further according to
Grass carries out cauline leaf process with herbicides such as isoproturons.The barley field grassy weed overwhelming majority after planting to emerging before the winter,
Emerged after winter and the beginning of spring seldom, catch after planting this section of material time medication to before surviving the winter, can effectively control grassy weed
Harm.
Fluorine chloropyridine ester is a kind of active component researched and developed by Tao benefit agriculture, can be used as pyridine carboxylic acid class herbicide, the work
The ISO common names of property composition get the Green Light in November, 2012.Tao benefit agriculture is entered for the methyl esters fluorine chloropyridine ester of the compound
The market development is gone, has been released in Canadian cereal crops market, for broad leaved weed prevention and control after bud.Contain removing for fluorine chloropyridine ester
Careless agent can be by preventing and kill off partial resistance weeds, and such as clearvers, chickweed and cannabis weeds carry out resistance management.In addition, fluorine chlorine
Pyridine ester can provide larger flexibility by microorganism fast degradation in the environment for succeeding crop plantation.
Tralkoxydim, CAS 87820-88-0, chemical name be 2- (l- (ethoxy imino) propyl group) -3- hydroxyls -
5- (2,4,6- trimethylphenyl) cyclohexene -2- ketone, also known as methoxyphenone, English name are tra l koxyd im.Belong to cyclohexene
Ketone selective herbicide, can effectively prevent and kill off and wheat and barley field, anti-deratization are applied to after a variety of grassy weeds of wheatland, bud
Tail amur foxtail, wind grass, oat, auspicious native rye grass, dog tail are early, after being absorbed through leaf, are transferred to growing point in bast, suppress herein
New growth.To broad leaved weed or sedge weed without obvious activity of weeding, but to grassy weed, quilt rapidly after foliage application
Plant absorbs and shifted.Weeds elder generation chlorosis, changes colour withered afterwards, completely withered in general 3~4 weeks.The effect of Control Wild oat is excellent
In preventive effect of the diclofop-methyl under recommended dose, and the optimum period for applying fertilizer is wide, almost can thoroughly prevent and kill off the wild oat before tiller final period,
The suppression phase can be extended down to the jointing stage.This product is also safe to wheat, barley under 2 times of maximum recommended dosage, including solids is small
Wheat.In low temperature cold current period, security is better than big fat horse.
Fluorine chloropyridine ester and tralkoxydim are single in use, there is certain defect and limitation.At present not on two
The compound medicine of person, other weeding Drug Combination Effects for barley field are nor highly desirable.
The content of the invention
It is an object of the invention to provide a kind of barley field weeding composition and its application, choose active ingredient tralkoxydim and
After fluorine chloropyridine ester is compounded, weeds can be effectively controlled, poisoning are reduced, especially for the weeds herbicidal effect of barley field
It is particularly pertinent.
An aspect of of the present present invention provides a kind of barley field weeding composition, including active ingredient and auxiliary element, effectively
Composition is fluorine chloropyridine ester and tralkoxydim, and the weight ratio of fluorine chloropyridine ester and tralkoxydim is 1:2-32.
As optimal technical scheme, the weight ratio of active ingredient fluorine chloropyridine ester and tralkoxydim is 1:2-24.
