Abstract
A herbicide for eliminating the graminaceous weeds and latifolious weeds in lawn is prepared from dicamba, fenoxaprop-P-ethyl, and auxiliary through proportionally mixing.
Description
Technical field
The present invention relates to a kind of prescription of weed killer herbicide, especially a kind of prescription of tall fescue turf herbicides special.
Background technology
Preventing and kill off at present of China's turf weed all pulled out based on the individual, but manually pulls out a lot of shortcomings: the weeds that efficient is low, weak effect, many weeds can not be eradicated, crawl to grow are difficult to pull out especially, therefore need special-purpose highly effective and safe lawn herbicide.Present domestic turf weed chemical control technology comparatively lacks, and still is in the research starting stage.Lawn herbicides special kind in the registration of medicine inspecting institute of the Ministry of Agriculture is few, and existing only have " elegant hundred palaces ", " it is swelled " to wait several kinds." elegant hundred palaces " are developed by Japanese Ishihara Sangyo Kaisha, Ltd., and its chemical name is " flazasulfuron ", is used for warm-season turfs such as Bermuda grass, Manila and prevents and kill off grass family, broad-leaved class and nutgrass flatsedge and sedge weed.But this medicament only is confined to the weed control of warm-season turf, can not use on cold-season type lawns such as Festuca Arundinacea, and cost is higher, and every mu of need are more than 80 yuan.Because the cost height, use seldom on the lawn of conventional environment greening, many now on golf course." it being swelled " is The Dow Agrosciences, LLC.'s exploitation, and its chemical name is " fluroxypyr ", is used for Gramineae lawn and prevents and kill off broad leaved weed.Although this medicine can use on cold-season type lawns such as Festuca Arundinacea, the grass spectrum is wideless extremely, can not prevent and kill off grassy weed and sedge weed in the lawn.Disclosed patent " high-efficiency special-use herbicide " also shows as the narrower grass spectrum of killing, and this invention is by " it is swelled " 8-8.5ml of 20%; " sulfonylureas " class weed killer herbicide 0.5-1g of 10%; " nonionic surface active agent " 1.5-2ml forms, and is specially adapted to kill cause malignant weed---the water peanut etc. of serious crop smothering for China's agricultural production.
Summary of the invention
The invention solves existing in prior technology weed killer herbicide cost higher, kill that the grass spectrum is wide, the technical problem of narrow application range etc., provide a kind of cost lower, can doublely control grassy weed, broad leaved weed and part sedge weed, active ingredient is the floating type weed killer herbicide of dicamba and high fenoxaprop-P.
Above-mentioned technical purpose of the present invention solves by the following technical programs: a kind of tall fescue turf herbicides special prescription, by effective ingredient dicamba (dicamba) 6.4-41.0%, high fenoxaprop-P (fenoxaprop-P-ethyl) 1.0-5.6% and auxiliary material mixed preparing form.
Dicamba, chemistry is by name 3, and 6-two chloro-O-Anisic Acids to then and perennial broadleaf weed, as Herba Galii Teneri, corn-bind, ox chickweed etc. good preventive effect is arranged, and gramineous plants such as paddy rice, corn etc. have good pesticide resistance to it.This medicament can be absorbed by the root of plant, leaf rapidly,, upwards conduction downward by phloem or xylem, and in meristematic tissue, accumulate, disturb the balance of endogenous growth element, its selectivity is mainly formed by metabolic degradation difference.Dicamba is a kind of high-efficiency low-toxicity dry land herbicide, can be by microbial decomposition in soil.This medicament phase mixcibility is good, stable storage.High fenoxaprop-P is a broad spectrum activity gramineous weed weedicide behind the interior suction seedling, is applicable to the broad leaf crop that all are important.It can decompose rapidly in soil, can not work the mischief to succession crop, and consumption is low, helps environmental protection.High fenoxaprop-P can be mixed with multiple weed killer herbicide, removes broad leaved weed, enlarges to kill the grass spectrum.This patent is mixed dicamba and high fenoxaprop-P, dicamba is to the preventive effect preferably of broad leaved weed, adding the preferably preventive effect of high fenoxaprop-P to grassy weed, make the grass spectrum of killing of this Mixed Pharmacy obviously enlarge, is a kind of weed killer herbicide with exploitation future.
As preferably, the auxiliary material of described tall fescue turf herbicides special is ethyl-phenol polyoxyethylene poly-oxygen propylene aether 4-12%, gas-phase silica 0.5-2.2%, thickener I (xanthans) 0.1-0.4%, thickener II (polyvinyl alcohol) 2.0-8.0%, kaolin 2.0-8.0%, ethylene glycol 1.0-4.0%, surplus is a water.After adding above various auxiliary materials, medicament can reach better effect in application.Gas-phase silica wherein (also claiming aerosil) is typical nano-powder material, has effects such as reinforcement, thickening and antisolvent precipitation, can strengthen the suspension character of medicament.The use of xanthans, polyvinyl alcohol has increased the concentration of medicament, can make the easier adhering to foliage of medicament when using, and makes effect more lasting.The used xanthans and the suitable concentration of polyvinyl alcohol are 0.2%, and institute's spent glycol is pure for analyzing, and also can use other purity.Phenethyl phenol polyoxyethylene poly-oxygen propylene aether of the present invention is ' 1601 ' (production of Lan Liang chemical plant).
As preferably, described tall fescue turf herbicides special prescription is dicamba 15-20%, high fenoxaprop-P 2.0-3.5%, phenethyl phenol polyoxyethylene poly-oxygen propylene aether 6-10%, gas-phase silica 0.8-1.6%, thickener I (xanthans) 0.1-0.3%, thickener II (polyvinyl alcohol) 3.0-5.0%, kaolin 3.0-5.0%, ethylene glycol 1.0-3.0%, surplus is a water.
Therefore, it is lower that the present invention has a cost, kill characteristics such as the grass spectrum is wider, can effectively prevent and kill off grass family main weeds such as lady's-grass, green foxtail, amur foxtail, annual bluegrass, also can effectively prevent and kill off the broad leaved weed that creeping oxalis, pennywort, humid euphorbia and plan lacquer mushroom etc. have serious harm, realize the efficient chemical weed control of tall fescue turf, reduce artificial, reduce the weeding cost, improved the lawn scenery effect simultaneously.
