Abstract
The invention belongs to the field of herbicides and relates to a mixed herbicide containing bentazone, nicosulfuron and atrazine and application thereof. The herbicide takes bentazone, nicosulfuron and atrazine as main active ingredients, wherein the mass ratio of bentazone to nicosulfuron to atrazine is (0.1-80):(0.1-80):(0.1-80) and the bentazone, nicosulfuron and atrazine account for 1-85wt% of the herbicide. The mixed herbicide has an obvious effect on postemergence weed control in corn fields, especially on controlling various grass and broadleaf weeds in the corn fields. Compared with the single agent, the herbicide delays weed resistance, has wide herbicidal spectrum and long efficacy duration and does no harm to the corns and the aftercrops on the premise of improving the pesticide effect.
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, nicosulfuron and atrazine.
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 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.
Atrazine (Atrazine) has another name called atrazine, a kind of triazine herbicide, and formal name used at school 2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazines, its structural formula:
Atrazine is before the selectivity inner sucting conduction type seedling, herbicide after seedling, is absorbed as the master with root, and cauline leaf absorbs seldom, is transmitted to plant meristematic tissue and leaf portion rapidly, disturbs photosynthesis that weeds are caused death.In resistance crop bodies such as corn, decomposed the generation innocuous substance by the corn ketolase, thereby to safety such as corns.Its spectrum of grass extremely is wider, can prevent and kill off multiple annual gramineae and broad leaved weed.Because atrazine is absorbed as the master with root, so that density takes place is higher when weeds, or plant is when big, and it is difficult to thoroughly cut weeds extremely, and, there have been many weeds that it has been produced serious resistance.
Nicosulfuron (nicosulfuron), other titles: Yu Nongle, cigarette sulphur swell, sulfonylurea herbicide, chemical name: 2-(4,6-dimethoxypyridin-2-base carbamyl aminosulfonyl)-N, the N-dimethyl nicotinamide, structural formula is as follows:
Nicosulfuron is interior absorption, high efficiency corn weed killer herbicide, behind the low dosage bud with preventing and kill off multiple annual gramineous weed, broad leaved weed and sedge weed in the corn field effectively.It is absorbed rapidly by leaf and root, and conducts rapidly by xylem and phloem, stops the synthetic of branched-chain amino acid by acetolactate synthestase.Weeds stop growing immediately after using nicosulfuron, and 4～5 days young leaves fade, necrosis, and progressively expand to whole plant, and general condition is handled back plant death in 20～25 days down.This medicine not only has cauline leaf processing effect, also has the preceding activity of weeding of bud.Corn has drug resistance preferably to this medicine, handles the back and temporary transient chlorisis or slight hypoevolutism occur, but generally can recover rapidly and the not underproduction.
Though nicosulfuron can effectively be prevented and kill off some broad leaved weed such as perennial grassy weed such as annual and false Chinese sorghum such as lady's-grass, green foxtail, Cowhells, barnyard grass grass, wild oat, the wheatgrass that crawls and chickweed, Amaranthus retroflexus, wrinkle fruit amaranth, piemarker, Siberian cocklebur, kitchen garden, also better to sedge weed preventive effects such as the rhizome ofs nutgrass flatsedge, but invalid substantially to Bermuda grass, Veronica.And because corn field uses sulfonylurea herbicide for a long time, many weeds have produced resistance.
Corn 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 corn 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, nicosulfuron and atrazine.
Another object of the present invention provides this herbicide applications.
A kind of mixed herbicide that contains bentazone, nicosulfuron and atrazine, it is characterized in that this weed killer herbicide is main active ingredient with bentazone, nicosulfuron and atrazine, the mass ratio of bentazone, nicosulfuron and atrazine is 0.1～80: 0.1～80: 0.1～80, and the mass ratio of preferred bentazone, nicosulfuron and atrazine is 1～60: 1～40: 1～60.
In mixed herbicide, bentazone, nicosulfuron and the atrazine 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, nicosulfuron and atrazine, except active ingredient bentazone, nicosulfuron and atrazine, 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 or wetting powder etc.
Mixed herbicide of the present invention can be used in the weed killer herbicide of preparation corn field postemergence weed control, particularly uses in various grass family or the broad leaved weed in preventing and kill off corn 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, 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 the 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 the corn field postemergence weed control, and it can prevent and kill off various grass family or broad leaved weed in the corn field, under the prerequisite that has improved drug effect, corn and succession crop is all had safety.
