Abstract
The invention discloses a herbicidal composition containing bentazone and clethodim. The herbicidal composition treats bentazone and clethodim as main effective components, wherein a mass ratio of bentazone to clethodim is 1-60:1-60. The herbicidal composition of the invention has an application of postemergent weeding in the soybean field, and especially has a substantial effect in controlling various grassy and broadleaf weeds in the soybean field. Compared with a single dose, the herbicidal composition of the present invention allows weed resistance delay, broad weeding spectrum, and long persistent period to be realized and has security to soybean and later crops on condition that the drug effect is improved.
Description
Technical field
The invention belongs to technical field of pesticide, weed killer herbicide field especially relates to the binary built Herbicidal combinations of bentazone and clethodim.This Herbicidal combinations can be applicable to soybean 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-2,2-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.
Clethodim has another name called and receives happy leading to.Chemical name: (±)-2-[(E)-3-chloroallyloxyamino imino group] propyl group-5-[2-(ethylmercapto group) propyl group]-3-hydroxyl hexamethylene-2-ketenes.Belong to the cyclohexenone analog weed killer herbicide, this weed killer herbicide is an inner sucting conduction type cauline leaf inorganic agent, and good selectivity is arranged, and grassy weed is had very strong lethal effect, to dicotyledonous crops safety.Cauline leaf is handled after leaf absorbs rapidly, be transmitted to meristematic tissue, in sensitive plant, suppress the biosynthesis of branched chain fatty acid and flavonoids and work, its cell division is destroyed, suppress the merismatic activity of plant, plant strain growth delayed, after the dispenser in 1-3 week plant move back green necrosis, it is withered and dead to burn with posterior lobe, effective to most of annual and perennial grassy weeds.In the resistance plant body, can degrade rapidly, form the polarity product, and loss of activity rapidly, to dicotyledon, the nutgrass flatsedge activity is very little or non-activity.But it is invalid to broad leaved weed.
Summary of the invention
The purpose of this invention is to provide a kind of Herbicidal combinations that contains bentazone and clethodim.
Another object of the present invention provides the application of this Herbicidal combinations in the weeding of soybean field.
A kind of Herbicidal combinations that contains bentazone and clethodim is characterized in that this Herbicidal combinations is main active ingredient with bentazone and clethodim, and the mass ratio of bentazone and clethodim is 1～60: 1～60.The mass ratio of preferred bentazone and clethodim is 1～40: 1～40, and further the preferred mass ratio is 1～20: 1～20, and most preferably mass ratio is 1～15: 1～10.
In Herbicidal combinations, the two quality percentage composition in Herbicidal combinations of bentazone and clethodim is 1～85%, and the preferred mass percentage composition is 10～75%.
In the binary built composition of bentazone of the present invention and clethodim, except active ingredients such as bentazone and clethodim, 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 postemergence weed control of soybean field, particularly uses to have remarkable result in preventing and kill off various grass family of soybean Tanaka 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.Clethodim 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 soybean and succession crop also is improved.
Safe.Herbicidal combinations of the present invention is applied to soybean field postemergence weed control, and it can prevent and kill off various grass family of soybean Tanaka and broad leaved weed, under the prerequisite that has improved drug effect, soybean 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 soybean field postemergence weed control, and particularly the weed killer herbicide that is used for preventing and kill off various grass family of soybean Tanaka and broad leaved weed in preparation is used.
