Abstract
The invention belongs to the field of herbicide, and discloses a mixed herbicide containing bentazone, propanil, and acifluorfen. The invention also discloses an application of the herbicide. The herbicide contains main effective components of bentazone, propanil, and acifluorfen. A mass ratio of bentazone to propanil to acifluorfen is 0.1-80:0.1-80:0.1-80. A total mass percentage of the three effective components in the herbicide is 1% to 85%. 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 the weed killer herbicide field, relate to a kind of mixed herbicide and application thereof that contains bentazone, Stam F-34 and acifluorfen.
Technical background
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 optionally herbicide after seedling of contact killing type tool, is used for cauline leaf processing in seedling stage, works by the blade contact.When in dry land, using, be transmitted to by the blade face infiltration earlier and suppress photosynthesis in the chloroplast.Can absorb by root again by the blade face infiltration when in the paddy field, using, be transmitted to cauline leaf, hinder weeds photosynthesis and water metabolism strongly, cause nutrition hunger, make physiological function lack of proper care and cause death.Bentazone active ingredient is detoxified to active weak glycoconjugates metabolism in the tolerable crop body, to crop safety, in 6-18 week after the dispenser, can be decomposed by microorganism in soil.But bentazone is invalid to grassy weed, and herbicidal spectrum is single.
Stam F-34 (Propanil), other titles: propanil, chemical name: N-(3 ', 4 '-dichlorophenyl) propionamide, structural formula is:
Stam F-34 is a kind of contact killing type weed killer herbicide of tool high selectivity, and rice seedling safety is had very strong action of contace poison to the barnyard grass grass.The effect of Stam F-34 is to destroy photosynthesis of plants, suppresses respiration and oxidative phosphorylation, and RNA and protein are synthetic etc., and the physiological function of the plant that is injured is affected, and accelerate dehydration, and blade is withered gradually, and is last dead.Stam F-34 is mainly used in rice seedling bed, live field and Honda and prevents and kill off barnyard grass grass, needle spikesedge herb.Also can be used for dry land and prevent and kill off weeds seedling such as lady's-grass, green foxtail, water starwort, Monochoria vaginalis, amaranth, amur foxtail.But invalid substantially to four leaf duckweeds, pondweed, wild water chestnut etc., herbicidal spectrum is single, and the control of weeds is had limitation.
Acifluorfen (acifluorfen-sodium), other titles: weeds are burnt, Da Keer, chemical name: 5-[2-chloro-4-(trifluoromethyl)-phenoxy group)-and 2-nitrobenzoic acid sodium, be a kind of diphenyl ether herbicide, its structural formula is:
Acifluorfen is a kind of tagging property weed killer herbicide, early time treatment behind the seedling, can be by the weeds stem, leaf absorbs, the mode of action is for tagging, can impel stomatal closure, by means of light performance activity of weeding, increase the plant corpus temperature and cause necrosis, and the transmission of inhibition mitochondria electronics, to cause the stagnation of respiratory system and energy production system, suppress cell division and make weeds death, can prevent and treat the black nightshade in the paddy field, knotweed, acalypha copperleaf, Amaranthus retroflexus, dayflower, artemisiifolia, piemarker, lamb's-quarters, Siberian cocklebur, annual broadleaf weeds such as beggar-ticks are to perennial corn sow thistle, field thistle, setose thistle, meadow pines etc. have stronger inhibitory action.But acifluorfen is invalid to grassy weed and nutgrass flatsedge, and paddy rice has the property of tagging poisoning, therefore, wants strict control consumption in the use, or with other herbicide mixtures, reduce poisoning and improve preventive effect to grassy weed.
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.
Summary of the invention:
The purpose of this invention is to provide a kind of mixed herbicide that contains bentazone, acifluorfen and Stam F-34.
Another object of the present invention provides the application of this weed killer herbicide in agent for removing grass in paddy field.
A kind of mixed herbicide that contains bentazone, acifluorfen and Stam F-34, it is characterized in that this weed killer herbicide is main active ingredient with bentazone, acifluorfen and Stam F-34, the mass ratio of bentazone, acifluorfen and Stam F-34 is 0.1～80: 0.1～80: 0.1～80, and the mass ratio of preferred bentazone, acifluorfen and Stam F-34 is 1～60: 1～50: 1～40.
In mixed herbicide, bentazone, acifluorfen and the Stam F-34 three gross mass percentage composition in weed killer herbicide is 1～85%, and preferred gross mass percentage composition is 20～75%.
In the ternary built preparation of bentazone of the present invention, acifluorfen and Stam F-34, except active ingredients such as bentazone, acifluorfen and Stam F-34, 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 suspending agent, missible oil, water dispersion granule, wetting powder or aqueous emulsion etc.
Mixed herbicide of the present invention can be used in the paddy field postemergence weed control, particularly uses in various grass family and the broad leaved weed to have remarkable result in preventing and kill off paddy field.
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 three kinds of different mechanism, makes weeds resistance generation speed reduce, and three kinds of composition Synergistics greatly improve the removing activity of weed killer herbicide.
2, herbicidal spectrum is wide, and the lasting period is long.Three kinds of weed killer herbicides to kill the grass spectrum different, the be mixed medicament that makes of three is combined herbicidal spectrum and the activity of various medicaments, make that the herbicidal spectrum of mix preparation is wideer, the lasting period is longer.
3, delay the weeds resistance.The present invention can significantly improve the preventive effect to various resistant weeds, delays the drug-fast generation of weeds, has prolonged the service life of medicament.
4, safe.Herbicidal composition 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.
