Abstract

The invention discloses a weeding composition containing bentazone, atrazine and sulcotrione, and application thereof. Bentazone, sulcotrione and atrazine are used as main active components of the weeding composition, and the mass ratio of bentazone to sulcotrione to atrazine is 1-80:1-80:1-80. The weeding composition provided in the invention has substantial effects in application of weeding after seedling emergence in a cornfield, especially in application of preventing and eliminating grassy and broadleaf weeds in the cornfield. Compared to a single weedicide, on the premise of improving drug effects, the weeding composition in the invention enables resistance of weeds to be delayed, has a broad weeding spectrum and a long persistent period, and is safe to maize and succeeding crops.

Description

A kind of Herbicidal combinations and application thereof that contains bentazone, sulphur humulone and atrazine
Technical field
The invention belongs to technical field of pesticide, weed killer herbicide field especially is specifically related to the ternary built Herbicidal combinations of a kind of bentazone, sulphur humulone and atrazine.This Herbicidal combinations can be applicable to the corn 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, the 2-dioxide, structural formula is:
Figure BSA00000150459100011
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.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 decomposed by microorganism 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:
Figure BSA00000150459100012
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.
Sulphur humulone (Sulcotrione), a kind of three ketones weed killer herbicide, formal name used at school 2-(2-chloro-4-methylsulfonyl) benzoyl-1, hydroresorcinol, its structural representation is as follows:
Figure BSA00000150459100021
The sulphur humulone is before the selectivity inner sucting conduction type maize seedling and herbicide after seedling, it can suppress the biosynthesis of carotenoid, it is dead that weeds are occurred after the albefaction, the sulphur humulone can effectively be prevented and kill off broadleaf weeds such as corn field dayflower, piemarker, knotweed, acalypha copperleaf, lamb's-quarters, Amaranthus retroflexus, monocotyledon weeds such as lady's-grass, barnyard grass grass, green foxtail also there is certain effect of preventing and kill off, to corn safety.Under normal crop rotation, to succession crop such as wheat class, rape, potato, beet safety.But the sulphur humulone is poor to the preventive effect of grassy weed, and herbicidal spectrum is comparatively narrow, therefore, has been subjected to certain restriction in the use.
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.Therefore, the present invention selects to kill grass spectrum difference, being made into mixture after the bentazone of pluses and minuses complementation, sulphur humulone and the suitable decrement of atrazine three all weed killer herbicides uses, so both enlarged and killed the grass spectrum, obviously improved herbicidal effect, also avoided this season is done the deposits yields poisoning and succession crop produced the possibility of residual hazard.
Summary of the invention
The purpose of this invention is to provide a kind of Herbicidal combinations that contains bentazone, sulphur humulone and atrazine.
Another object of the present invention provides the application of this Herbicidal combinations in cornfield weeding.
A kind of Herbicidal combinations that contains bentazone, sulphur humulone and atrazine, it is characterized in that this Herbicidal combinations is main active ingredient with bentazone, sulphur humulone and atrazine, the mass ratio of bentazone, sulphur humulone and atrazine is 1~80: 1~80: 1~80, the mass ratio of preferred bentazone, sulphur humulone and atrazine is 1~60: 1~40: 1~60, most preferably 1~10: 1~10: 1~10.
In Herbicidal combinations, bentazone, sulphur humulone and the atrazine three quality percentage composition in Herbicidal combinations is 1~75%, and the preferred mass percentage composition is 20~65%.
In the ternary recompounded composite of bentazone of the present invention, sulphur humulone and atrazine, except active ingredients such as bentazone, sulphur humulone 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, wetting powder etc.
Herbicidal combinations of the present invention can be used in the corn field postemergence weed control, particularly uses in grass family and the broad leaved weed to have remarkable result in preventing and kill off corn field.
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 three 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.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 combinations of the present invention is applied to the corn field postemergence weed control, and it can prevent and kill off various grass family and broad leaved weed in the corn field, under the prerequisite that has improved drug effect, corn and succession crop is all had safety.
Therefore, Herbicidal combinations of the present invention can be used in the weed killer herbicide for the preparation of the corn field postemergence weed control, particularly uses in for the preparation of the weed killer herbicide of preventing and kill off grass family and broad leaved weed in the corn field.
