Abstract
The invention belongs to the field of herbicide, and discloses a mixed herbicide containing bentazone and molinate. The invention also discloses an application of the herbicide. The herbicide contains main effective components of bentazone and molinate. A mass ratio of bentazone to molinate is 1-80:1-80. The mixed herbicide provided by the present invention has substantial effects in the application in paddy field post-seedling weeding, and especially in the application in controlling various poaceae and broad leaf weeds in paddy fields. Compared to single recipe herbicides, with the herbicide provided by the invention, the herbicide potency is improved, the weed resistance is retarded, the herbicide spectrum is wide, the effective duration is long, and safety is brought to paddy and succeeding 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 molinate, 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.
Molinate has another name called molinate, molinate, ordram, chemical name: N, and N-hexa-methylene dithiocarbamate-s-ethyl, its structural formula is as follows:
Molinate is the herbicides for use in paddy with systemic action.Can be absorbed by root of weeds and bud.Especially easily absorbed by bud scale.Barnyard grass grass, fescue, difformed galingale herb there is special efficacy.And suitable period broad.But it is narrow to kill the grass spectrum, and invalid to broad leaved weed and perennial perennial root weeds, herbicidal spectrum is single, and the control of weeds is had limitation.
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 molinate 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 molinate.
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 molinate, it is characterized in that this Herbicidal combinations is main active ingredient with bentazone and molinate, wherein, the mass ratio of bentazone and molinate is 1～80: 1～80, and the mass ratio of preferred bentazone and molinate is 1～50: 1～50.
In Herbicidal combinations, the two quality percentage composition in Herbicidal combinations of bentazone and molinate is 1～85%, and the preferred mass percentage composition is 10～75%.
In the binary built composition of bentazone of the present invention and molinate, except active ingredients such as bentazone and molinate, 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 for the paddy field postemergence weed control, uses and has remarkable result especially for preventing and kill off in the paddy field grass family and broad leaved weed.
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.Molinate 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 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 various grass family and 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 at the weed killer herbicide that preparation is used for the paddy field postemergence weed control, particularly uses in preparation is used for preventing and kill off the weed killer herbicide of paddy field grass family and broad leaved weed.
