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 containing bentazone, nicosulfuron and atrazine.
Technical background
Bentazone has another name called Lysimachia sikokiana pellet, Bentazon, chemical name: 3-isopropyl-(1H)-benzo-2,1, and 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, for cauline leaf processing in seedling stage, by blade, contacts and works.Dry land is used, and first by blade face, permeates and is transmitted to inhibited photosynthesis in chloroplast.Paddy field is used and can permeate and can pass through root absorption by blade face, is transmitted to cauline leaf, strongly hinders weeds photosynthesis and water metabolism, causes nutrition hunger, and physiological function is lacked of proper care and lethal.Active ingredient is detoxified to active weak glycoconjugates metabolism in the tolerable crop body, and to crop safety, after dispenser, 6-18 week bentazone can be decomposed by microorganism in soil.But bentazone is invalid to grassy weed, herbicidal spectrum is single.
Atrazine (Atrazine), have another name called atrazine, a kind of triazine herbicide, and the chloro-4-ethylamino of formal name used at school 2--6-isopropylamino-1,3,5-triazines, its structural formula:
Atrazine is before selectivity inner sucting conduction type seedling, herbicide after seedling, take root absorption as main, and cauline leaf absorbs seldom, is transmitted to rapidly plant meristematic tissue and leaf section, disturbs photosynthesis to make weeds lethal.In the resistance crop bodies such as corn, decomposed and generate innocuous substance by the corn ketolase, thereby to safety such as corns.Its herbicide spectrum is wider, can prevent and kill off multiple annual gramineae and broad leaved weed.Because atrazine be take root absorption as main, thus when weeds generation density higher, or plant is when larger, it is difficult to thoroughly kill and cut weeds, and, had many weeds to produce serious resistance to it.
Nicosulfuron (nicosulfuron), other titles: Yu Nongle, cigarette sulphur are grand, 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, after the low dosage bud with effectively preventing and kill off multiple annual gramineous weed, broad leaved weed and sedge weed in corn field.It is absorbed rapidly by leaf and root, and conducts rapidly by xylem and phloem, by acetolactate synthestase, stops the synthetic of branched-chain amino acid.After using nicosulfuron, weeds stop growing immediately, and 4～5 days young leaves fade, necrosis, and progressively expand to whole plant, plant death in 20～25 days after processing under general condition.This medicine not only has cauline leaf processing effect, also has the front activity of weeding of bud.Corn has drug resistance preferably to this medicine, temporary transient chlorisis or slight hypoevolutism occur after processing, but generally can recover rapidly and the not underproduction.
Although nicosulfuron can effectively be prevented and kill off some broad leaved weed such as the perennial grassy weed such as the annual and false Chinese sorghum such as lady's-grass, green foxtail, Cowhells, barnyard 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 substantially invalid to Bermuda grass, Veronica.And, because corn field is used sulfonylurea herbicide for a long time, many weeds have produced resistance.
Corn field herbicide is limit by crop safety at present, the herbicide spectrum is also limited, use separately a kind of weed killer herbicide single dose can not control completely effectively the generation of corn field weed, moreover some weed killer herbicide is due to water-soluble large or the field lasting period is oversize, consumption is excessive or dispenser is inhomogeneous all easily causes the residual hazard to this season crop or succession crop.
Summary of the invention:
The purpose of this invention is to provide a kind of mixed herbicide containing bentazone, nicosulfuron and atrazine.
Another object of the present invention is to provide the application of this weed killer herbicide.
A kind of mixed herbicide containing bentazone, nicosulfuron and atrazine, it is characterized in that this weed killer herbicide take bentazone, nicosulfuron and atrazine as main active ingredient, the mass ratio of bentazone, nicosulfuron and atrazine is 0.1～80: 0.1～80: 0.1～80, and preferably the mass ratio of 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 preferably the 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 pesticidal preparations and be mixed with any one formulation allowed on 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 applied in the weed killer herbicide for preparing the corn field postemergence weed control, particularly in preventing and kill off corn field, in various grass family or broad leaved weed, applies.
Herbicidal composition of the present invention has the following advantages:
1, activity of weeding is high.Herbicidal composition of the present invention can kill weeds by three kinds of different mechanism, makes Weed Resistance produce Speed Reduction, 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.The herbicide of three kinds of weed killer herbicides spectrum is different, and the three is combined to herbicidal spectrum and the activity of these three kinds of medicaments with the be mixed medicament that makes of special ratios, makes the herbicidal spectrum of mix preparation wider, and the lasting period is longer.
3, delay Weed Resistance.The present invention can significantly improve the preventive effect to various resistant weeds, delays the generation of herbicide resistance, extends the service life of medicament.
4, safe.Herbicidal composition of the present invention, be applied to the corn field postemergence weed control, and it can prevent and kill off various grass family or broad leaved weed in corn field, under the prerequisite that has improved drug effect, corn and succession crop all had to safety.
