Abstract
The invention discloses a weeding composition containing bentazone and quinclorac. The weeding composition comprises main effective components of bentazone and quinclorac in a mass ratio of 1-60:1-60. The weeding composition of the invention can be applied to weeding after seedling in rice field, and especially has substantial effects on control of barnyard grass and various broad leaf weeds in rice field. Compared with a single dose, the weeding composition of the invention, on the premise of enhancing drug effect, delays weed resistance, has a wide weeding spectrum and a long persistent period, and is safe to rice and later crops.
Description
Technical field
The invention belongs to technical field of pesticide, especially the weed killer herbicide field is specifically related to a kind of Herbicidal combinations and application thereof that contains bentazone and dichloro quinolinic acid, and this Herbicidal combinations can be applicable to the paddy field 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, the 2-dioxide, structural formula is:
This weed killer herbicide is an optionally herbicide after seedling of contact killing type tool, is used for cauline leaf processing in seedling stage, works 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.
Other title of dichloro quinolinic acid (Quinclorac): quinclorac.Belong to hormone-type quinoline carboxylic acid weed killer herbicide.Chemical name is: 3, and 7-two chloro-8-Quinoline Carboxylic Acids, structural formula is:
Dichloro quinolinic acid is a herbicide for paddy field.Be mainly used in anti-barnyard grass grass.Also can prevent and treat Monochoria korsakowii, sesbania, Chinese celery, Monochoria vaginalis, Chinese honey locust.And suitable period broad, the barnyard grass grass 1-7 leaf phase all can use.But it is narrow to kill the grass spectrum, and residual quantity is bigger in the soil, and the back stubble is easily produced poisoning, therefore, and many and other herbicide mixtures in the use.
Herbicide for paddy field is limit by crop safety at present, it is also limited to kill the grass spectrum, be used alone the agent of weed killer herbicide list and can not control the generation of paddy field weed completely effectively, moreover some weed killer herbicide is because water-soluble big or the field lasting period is oversize, consumption is excessive or the inhomogeneous residual hazard that all causes easily this season crop or succession crop of dispenser.Therefore, the present invention selects to kill grass spectrum difference, being made into mixture after two kinds of suitable decrements of weed killer herbicide of the bentazone of pluses and minuses complementation and dichloro quinolinic acid uses, so both enlarged and killed the grass spectrum, obviously improved herbicidal effect, also avoided this season is done the deposits yields poisoning and succession crop produced the possibility of residual hazard.
Summary of the invention
The purpose of this invention is to provide a kind of Herbicidal combinations that contains bentazone and dichloro quinolinic acid.
Another object of the present invention provides the application of this Herbicidal combinations in agent for removing grass in paddy field.
A kind of Herbicidal combinations that contains bentazone and dichloro quinolinic acid, it is characterized in that this Herbicidal combinations is main active ingredient with bentazone and dichloro quinolinic acid, wherein, the mass ratio of bentazone and dichloro quinolinic acid is 1～60: 1～60, the mass ratio of preferred bentazone and dichloro quinolinic acid is 1～40: 1～50, further preferred 1～30: 1～30, most preferably 1～10: 1～10.
In Herbicidal combinations, the two quality percentage composition in Herbicidal combinations of bentazone and dichloro quinolinic acid is 1～85%, and the preferred mass percentage composition is 10～75%.
In the binary built preparation of bentazone of the present invention and dichloro quinolinic acid, except active ingredients such as bentazone and dichloro quinolinic acid, 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, emulsifiable concentrate, microemulsion, water dispersion granule, wetting powder etc.
Herbicidal combinations of the present invention can be used at the weed killer herbicide that preparation is used for the paddy field postemergence weed control, particularly is used for preventing and kill off paddy field barnyard grass grass and multiple broad leaved weed has remarkable result in preparation.
Herbicidal combinations of the present invention has the following advantages:
1, activity of weeding height.Herbicidal combinations 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.Dichloro quinolinic acid 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.After both mix, can improve control to barnyard grass grass and multiple broad leaved weed.
3, delay the weeds resistance.Herbicidal combinations 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 paddy rice and succession crop also is improved.
Safe.Herbicidal combinations of the present invention is applied to the paddy field postemergence weed control, and it can prevent and kill off barnyard grass grass and multiple broad leaved weed in the paddy field, under the prerequisite that has improved drug effect, paddy rice and succession crop is all had safety.
Therefore, Herbicidal combinations of the present invention can be used in the weed killer herbicide of preparation paddy field postemergence weed control, particularly uses in preparation is used for preventing and kill off the weed killer herbicide of paddy field barnyard grass grass and broad leaved weed.
