Abstract
The invention belongs to the field of herbicide, and relates to a mixed herbicide containing bentazone, acifluorfen and quizalofop-p-ethyl, and application thereof. The herbicide comprises main effective components of bentazone, acifluorfen and quizalofop-p-ethyl in a mass ratio of 0.1-80:0.1-80:0.1-80, and the three accounts for 1-85wt% in the herbicide. The mixed herbicide can be applied to weeding after seedling in soybean field, and has a substantial effect on application to control of gramineae weeds and broad leaf weeds in soybean field. Compared with a single dose, the herbicide of theinvention, on the premise of enhancing drug effect, delays weed resistance, has a wide weeding spectrum and a long persistent period, and is safe to soybean and later crops.
Description
Technical field
This patent belongs to the weed killer herbicide field, relates to a kind of mixed herbicide and application thereof that contains bentazone, acifluorfen and Quizalotop-ethyl.
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.
Quizalotop-ethyl has another name called smart quizalofopethyl, the spirit of lid grass, chemical name: (R)-2-[4-(6-chloro-quinoxaline-2-base oxygen) phenoxy group] ethyl propionate, structural formula is:
Quizalotop-ethyl is the highly finished product removed inactive optical isomer (L-body) in the process of synthetic quizalofopethyl after.Its mechanism of action is to absorb by the weeds cauline leaf, and two-way conduction up and down is accumulated in top and intercalary meristem in plant corpus, and it is synthetic to suppress cell fatty acid, makes the weeds necrosis.Smart quizalofopethyl is optionally novel dry land cauline leaf inorganic agent of a kind of high speed, and the selectivity of height is arranged between grassy weed and dicotyledonous crops, and the grassy weed on the broad leaf crop is had good preventive effect.Smart quizalofopethyl improved by plant absorbing and in plant mobility, so speed of action is faster, drug effect is more stable, is not subject to the influence of environmental conditions such as rainwater, temperature and humidity, and is environmentally safe.But because Quizalotop-ethyl is used in the soybean field for a long time, some weeds have produced serious resistance to it.
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, is applied to early stage weeding behind the seedling, can be absorbed by weeds stem, leaf, and the mode of action is for tagging.It 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 annual broadleaf weeds such as black nightshade in the paddy field, knotweed, acalypha copperleaf, Amaranthus retroflexus, dayflower, artemisiifolia, piemarker, lamb's-quarters, Siberian cocklebur, beggar-ticks, perennial corn sow thistle, field thistle, setose thistle, meadow pine etc. are had stronger inhibitory action.But acifluorfen is invalid to grassy weed and nutgrass flatsedge, and soybean is had 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.
Soybean field herbicide 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 soybean weeds 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 Quizalotop-ethyl.
Another object of the present invention provides this herbicide applications.
A kind of mixed herbicide that contains bentazone, acifluorfen and Quizalotop-ethyl, it is characterized in that this weed killer herbicide is main active ingredient with bentazone, acifluorfen and Quizalotop-ethyl, the mass ratio of bentazone, acifluorfen and Quizalotop-ethyl is 0.1～80: 0.1～80: 0.1～80, and the mass ratio of preferred bentazone, acifluorfen and Quizalotop-ethyl is 1～60: 1～50: 1～40.
In mixed herbicide, bentazone, acifluorfen and the Quizalotop-ethyl 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 Quizalotop-ethyl, except active ingredient bentazone, acifluorfen and Quizalotop-ethyl, 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.
Mixed herbicide of the present invention can be used in the weed killer herbicide of preparation soybean field postemergence weed control, particularly uses in preventing and kill off the various grass family of soybean Tanaka and broad leaved weed.
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 has greatly improved 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 three is combined herbicidal spectrum and the activity of these three kinds of medicaments with the be mixed medicament that makes of special ratios, 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, prolongs the service life of medicament.
4, safe.Herbicidal composition of the present invention is applied to soybean field postemergence weed control, and it can prevent and kill off the various grass family of soybean Tanaka or broad leaved weed, under the prerequisite that has improved drug effect, soybean and succession crop is all had safety.
