Description
Technical field
The invention belongs to technical field of pesticide, particularly a kind of Wheat field weeding composition and pharmaceutical preparation thereof.
Background technology
Wheat is one of northern China staple food crop, and it is rich in starch, protein, fat, mineral matter, calcium, iron, thiamine, vitamin b3, nicotinic acid and vitamin A etc., is the cereal crops of gross yield second in the world.Wheat, more than 3,000 ten thousand hectares of the long-term cultivated areas of China, is only second to Monitoring of Paddy Rice Plant Area.According to statistics, most of wheat paddock always has crop smothering in various degree to occur, and crop smothering area accounts for the more than 55% of wheat planting area, and wherein serious harm area accounts for 28%, and lost units accounts for 15% left and right of wheat gross yield.Along with the development of agricultural cience and farming techniques, the application of chemical herbicide as saving of labor, save time, one of cost-effective strong weeding, well stimulation.
Weeding for wheat agent kind is more, can be divided into cauline leaf process weed killer herbicide and closed soil treatment weed killer herbicide according to application method.Cauline leaf is processed weed killer herbicide and is referred to after weeds emerge, directly be applied to the medicament that weeds cauline leaf kills weeds, its using method is for to be diluted in weed killer herbicide in a certain amount of water, weeds seedling is sprayed to processing, by weeds cauline leaf, the absorption of medicine and conduction are eliminated to weeds, for example, fenoxapropPethyl.Closed soil treatment weed killer herbicide in use, is spread on upper soll layer weed killer herbicide or admixes in soil by mixed native operation handlebar weed killer herbicide, sets up a weed killer herbicide confining bed, to kill the weeds of sprouting; This class weed killer herbicide can be played a role by absorptions such as the root of weeds, tooth sheath or upper hypocotyls, as isoproturon, butachlor etc.
At present, conventional weeding for wheat agent is that cauline leaf is processed weed killer herbicide, but this class weed killer herbicide only produces effect to unearthed weeds, and this just needs repeatedly dispenser, and service time is long.Along with cauline leaf is processed a large amount of use year after year of weed killer herbicide, some weeds has produced very strong resistance, such as Alopecurus, Wang grass etc., and this resistance can be more and more stronger.Closed soil treatment weed killer herbicide is easy to use, cost is lower.But in weeding for wheat agent, relatively seldom, one of reason is, when weed killer herbicide use is processed in some kind sealing, poisoning, for example butachlor, Acetochlor class weed killer herbicide easily occurs when there is ponding in field in the use of closed soil treatment weed killer herbicide.Now developed some closed soil treatment weed killer herbicides, can avoid the generation of this class poisoning, but closed soil treatment weed killer herbicide also exists another one problem,, after weeds emerge, substantially there is no control efficiency, service time is shorter.So, be badly in need of the wheat paddock weed killer herbicide that a kind of control efficiency is good, the control time is long.
Summary of the invention
In view of this, goal of the invention of the present invention is to provide a kind of Wheat field weeding composition and pharmaceutical preparation thereof.The control efficiency of this Wheat field weeding composition is good, service time is long, can effectively prevent and treat wheat paddock crop smothering, can be prepared into suspending agent, wetting powder or water dispersible granules, can be used as wheat paddock closed soil treatment weed killer herbicide and use, also can be used as wheat paddock cauline leaf and process weed killer herbicide use.
For realizing goal of the invention of the present invention, the invention provides following technical scheme:
The invention provides a kind of Wheat field weeding composition, its component by following weight portion forms:
20～80 parts of isoproturons
2～20 parts of diflufenicans
2～20 parts of flufenacets.
Isoproturon is substituted urea class selective herbicide.After isoproturon medicament is absorbed by plant root, conduct and be accumulated in blade, inhibited photosynthesis, causes weeds dead.Can be used for preventing and kill off wheat paddock annual weed, as lady's-grass, amur foxtail, Alopecurus, annual bluegrass, hard Cao, Wang grass, wild oat, Hairy Bittercress, tongue of sparrow grass, lamb's-quarters, cyclophanes thread etc.Isoproturon is met rain or is poured water after medication, can improve herbicidal effect.
Diflufenican belongs to substituted pyridinyl acyl aniline herbicide, and this weed killer herbicide is mainly used in corn, soybean and wheatland and prevents and kill off multiple annual gramineous weed and some broad leaved weed.This kind is selective exposure and residual weed killer herbicide, and the mode of action is for passing through the inhibition to phytoene dehydrogenase, and the biosynthesis of obstruction class carotene, causes Destruction of Chlorophyll and cell rupture, and plant is dead.Compare with other picolinamide class weed killer herbicides, diflufenican has that activity of weeding is high, the duration is long, be difficult for decomposing, the feature to Crop securify.
Flufenacet is fragrant oxanamide class weed killer herbicide, mainly by suppressing cell division, plays a role, and can effectively prevent and kill off numerous annual gramineous weeds, as before the seedling of Annual Ryegrass etc. and some broad leaved weed and early stage after seedling.Flufenacet be fluorine-containing, containing heterocycle herbicide, there is the advantages such as the high and low poison of removing activity, broad weed-killing spectrum, applicable crops are wide, high safety, it meets the new trend of current pesticide research exploitation.Compare with mefenacet, flufenacet has higher activity, is suitable for preventing and kill off multiple weeds.
Different herbicidal activity components are mixed rear each active component due to the difference of composition, structure, physicochemical property, make the synergy between each active component be usually expressed as synergistic effect, summation action or antagonism.So-called synergistic effect is exactly the mutual synergism between different material, and the effect of its generation is greater than the sum total of each composition effect; And the effect that summation action is exactly its generation equals the sum total of each composition effect; Antagonism refers to when two kinds of materials act on living organism, has produced the effect that a kind of material disturbs another material, or the effect of interfering with an opponent each other, the phenomenon that general effect is declined.
The present invention has utilized the different mechanisms of action of isoproturon, diflufenican, three kinds of weed killer herbicides of flufenacet dexterously, three is carried out composite, has reached synergistic effect.The present invention evaluates the interaction after composite of three kinds of different activities components in Wheat field weeding composition provided by the invention with reference to co-toxicity coefficient method, wherein, co-toxicity coefficient >120 is synergistic effect, co-toxicity coefficient is expressed as summation action between 80～120, and co-toxicity coefficient <80 is expressed as antagonism.Experimental result confirmation, Wheat field weeding composition provided by the invention can be used as wheat paddock closed soil treatment weed killer herbicide and uses, and the co-toxicity coefficient >120 of this Wheat field weeding composition, is synergistic effect.Experimental result also shows, Wheat field weeding composition provided by the invention can effectively be prevented and kill off the amur foxtail, Wang grass that existing weed killer herbicide has been produced to very strong resistance; And this Wheat field weeding composition does not produce poisoning, on the not impact of the normal growth of wheat, can effectively prevent and treat for a long time wheat paddock crop smothering.In addition, Wheat field weeding composition provided by the invention is wider service time, from seedling, all can use to 21 heart stages of leaf of weeds.
