Abstract
The invention discloses a weed control composition containing bentazone and clodinafop-propargyl, and a use thereof. Main active ingredients of the weed control composition comprise bentazone and clodinafop-propargyl, wherein a mass ratio of bentazone to clodinafop-propargyl is (1 to 80): (1 to 80). The weed control composition has obvious application effects in weeding after seedling emergence in a wheat field, and control of various gramineous or latifoliate weeds in a wheat field. Compared with a weed control composition containing a single ingredient, under the premise of improvement of weed control effects, the weed control composition has the characteristics of delay of herbicide resistance of weeds, broad weeding spectrum, long persistent period and safety on wheat and subsequent crops.
Description
Technical field
The invention belongs to technical field of pesticide, weed killer herbicide field especially is specifically related to the binary built Herbicidal combinations of a kind of bentazone and alkynes grass ester.This herbicidal composition can be applicable to the wheat paddock postemergence weed control.
Background technology
Bentazone has another name called Lysimachia sikokiana pellet, Bentazon.Chemical name: the 3-isopropyl-(1H)-and benzo-2,1,3-thiadiazine-4-ketone-2,2-dioxide, this weed killer herbicide are optionally herbicide after seedling of contact killing type tool, are used for cauline leaf processing in seedling stage, work by the blade contact.Dry land is used, and is transmitted to by the blade face infiltration earlier and suppresses photosynthesis in the chloroplast.The paddy field is used and can be absorbed by root again by the blade face infiltration, is transmitted to cauline leaf, hinders weeds photosynthesis and water metabolism strongly, causes nutrition hunger, makes physiological function lack of proper care and cause death.Active ingredient is detoxified to active weak glycoconjugates metabolism in the tolerable crop body, and to crop safety, 6-18 week bentazone can be by microbial decomposition in soil after the dispenser.But bentazone is invalid to grassy weed, and herbicidal spectrum is single.
Alkynes grass ester (Clodinafop-propargyl), have another name called the wheat utmost point, chemical name: (R)-2-(4-(3-fluoro-5-chloro-2-pyridine oxygen base) phenoxy group) propionic acid propynyl ester, belong to fragrant phenoxy propionic acid class weed killer herbicide, the biosynthesis that can effectively suppress the class ester is the auxilliary quick A hydroxylase inhibitors of acetyl, is cauline leaf inorganic agent behind the selectivity inner sucting conduction type seedling.But alkynes grass ester in use must be used with safener, and alkynes grass ester is invalid to broad leaved weed, and herbicidal spectrum is narrow, and it is restricted in the use.
Summary of the invention
The purpose of this invention is to provide a kind of Herbicidal combinations that contains bentazone and alkynes grass ester.
Another object of the present invention provides the application of this Herbicidal combinations in the wheat paddock weeding.
A kind of Herbicidal combinations that contains bentazone and alkynes grass ester is characterized in that this Herbicidal combinations is main active ingredient with bentazone and alkynes grass ester, and the mass ratio of bentazone and alkynes grass ester is 1～80: 1～80.The mass ratio of preferred bentazone and alkynes grass ester is 1～30: 1～50, and further the preferred mass ratio is 1～20: 1～20, and most preferably mass ratio is 1～10: 1～15.
In Herbicidal combinations, bentazone and the two quality percentage composition in Herbicidal combinations of alkynes grass ester are 1～85%, and the preferred mass percentage composition is 10～70%.
In the binary built composition of bentazone of the present invention and alkynes grass ester, except active ingredients such as bentazone and alkynes grass ester, can also add the auxiliary agents such as conventional surfactants, thickener, solvent or solid packing that allow on the pesticidal preparations and be mixed with any one formulation that allows on the agricultural chemicals.Preferably be processed into missible oil, suspending agent, aqueous emulsion, microemulsion, water dispersion granule, wetting powder etc.
Herbicidal combinations of the present invention can be used in the wheat paddock postemergence weed control, particularly uses in various grass family and the broad leaved weed to have remarkable result in preventing and kill off wheat paddock.
Herbicidal composition of the present invention has the following advantages:
1, activity of weeding height.Herbicidal composition of the present invention can kill weeds by two kinds of different mechanism, makes weeds resistance generation speed reduce, and greatly improves the removing activity of weed killer herbicide.
2, herbicidal spectrum is wide, and the lasting period is long.Alkynes grass ester is the broad spectrum weeding agent, and it has good preventive effect to annual gramineous weed, and bentazone is a weed killer herbicide of preventing and kill off broad leaved weed.Both can improve the control to multiple grassy weed and broad leaved weed after mixing.
3, delay the weeds resistance.Weed killer herbicide of the present invention reduces the resistance of weeds to medicament by binary built, and improves the preventive effect of antagonism weeds, thereby prolongs the service life of medicament.
4, safe.Because its using dosage is under control, and makes medicament under the prerequisite that has improved drug effect, its safety to wheat and succession crop also is improved.
Safe.Herbicidal composition of the present invention is applied to the wheat paddock postemergence weed control, and it can prevent and kill off various grass family and broad leaved weed in the wheat paddock, under the prerequisite that has improved drug effect, wheat and succession crop is all had safety.
Therefore, Herbicidal combinations of the present invention can be used at the weed killer herbicide that preparation is used for the wheat paddock postemergence weed control, particularly uses in preparation is used for preventing and kill off the weed killer herbicide of wheat paddock grass family and broad leaved weed.
