Abstract
The invention belongs to the field of pesticides and herbicides, and in particular relates to wettable powder containing diflufenican and oxadiazon. The wettable powder contains the following ingredients in content by weight: 1-30 percent of diflufenican, 1-60 percent of oxadiazon, 5-20 percent of surfactant, and 10-80 percent of filler; and the total weight content of all the ingredients is 100 percent. The composition is mainly used for controlling annual broadleaf weeds and gramineous weeds in garlic, wheat and paddy fields. The composition has the characteristics of synergistic effect, expansion in herbicidal spectrum, delay in herbicide resistance and low cost.
Description
Technical field
The invention belongs to the agricultural herbicide field, particularly contain Diflufenican with the wetting powder of Evil humulone.
Background technology
Diflufenican belongs to the carotenoid biosynthesis inhibitor, is the selectivity cornfield herbicidal of wide spectrum, causes Destruction of Chlorophyll and cell rupture, and plant is dead.To impose on autumn sowing Wheat and barley field before 125~250g/ha bud or behind the bud, prevent and kill off grass family and broad leaved weed, especially clearvers, Veronica and violet weeds.This medicament has following characteristics: broad weed-killing spectrum; But keeping from ill weeds; The drug effect phase is long in the soil; Efficacy stability; Can be mixed with other weed killer herbicides, enlarge the herbicide spectrum.
The Evil humulone has another name called Lonster, farming is thought it, is before the selectivity bud, post-emergence herbicide.Main by weeds young shoot or cauline leaf absorption.Weeds effect to germination period is best, and is along with weeds grow up and effect decline, substantially invalid to the strain weeds.Be applicable to the crops such as paddy rice, soybean, cotton, sugarcane and orchard and prevent and kill off the annual gramineae broad leaved weeds such as barnyard grass, moleplant seed, ditch millet, difformed galingale herb, globe daisy alkali grass, Monochoria vaginalis, Sagittaria pygmaea, Drilgrass and Amaranthaceae, Chenopodiaceae, Euphorbiaceae, Oxalidaceae, Convolvulaceae.
The different cultivars composition carries out composite, is the modal method of control resistant weed.Heterogeneity is carried out composite, can improve preventive effect, enlarges the consumption of herbicide spectrum, minimizing active ingredient, saves drug cost, reduces environmental pollution, is the important means of integrated control weeds in field.
Through retrieval, do not find Diflufenican at present Yu the Evil humulone is composite and the document of application.
Summary of the invention
For addressing the above problem, what the object of the present invention is to provide a kind of good drug efficacy contains Diflufenican with the wetting powder of Evil humulone.
Technical scheme of the present invention is: a kind ofly contain Diflufenican with the wetting powder of Evil humulone:
Its component and weight content are as follows:
Diflufenican 1%~30%

Surfactant 5%~20%
Filler 10%~80%
Each composition weight content sum is 100%;
Described surfactant is selected from one or more in emulsifier, dispersant, wetting agent or the bleeding agent.
Above-mentioned active ingredient Diflufenican can be buied by various commercial channel Yu the Evil humulone all is weed killer herbicides well known in the art.
Surfactant can be emulsifier, dispersant, wetting agent or bleeding agent, can be nonionic or anionic, also can be two or more compound uses.
Described emulsifier is selected from agricultural newborn 500#(alkyl benzene calcium sulfonate), OP series phosphate (polyoxyethylene nonylphenol ether phosphate), 600# phosphate (phenyl phenol polyoxyethylene ether phosphate), styrene polyoxyethylene ether ammonium sulfate salt, alkyl biphenyl ether disulfonic acid magnesium salts, triethanolamine salt, the newborn 400#(benzyl dimethyl phenol polyoxy ethyl ether of farming), Nongru-700 #(alkylphenol-formaldehyde resin polyoxy ethyl ether), peaceful newborn 36#(phenethyl fluosite polyoxy ethyl ether), the newborn 1600#(phenethyl phenol polyoxy ethyl polypropylene-base ether of farming), ethylene oxide-propylene oxide block copolymer, OP series (polyoxyethylene nonylphenol ether), BY series (castor oil polyoxyethylene ether), the newborn 33#(alkylaryl polyoxyethylene poly-oxygen propylene aether of farming), sapn series (sorbitol anhydride monostearate), in tween series (anhydrous sorbitol resin acid ester APEO) or the AEO series (fatty alcohol-polyoxyethylene ether) one or more.
Described dispersant is selected from one or more in polycarboxylate, lignosulfonates, alkylphenol polyoxyethylene formaldehyde condensation products sulphate, alkyl benzene calcium sulfonate, naphthalene sulfonic acid-formaldehyde condensation product sodium salt, alkylphenol polyoxyethylene, aliphatic amine polyoxyethylene ether, aliphatic acid polyethenoxy ether or the fatty acid glyceride APEO.
Described wetting agent is selected from one or more in lauryl sodium sulfate, neopelex, Nekal BX, wetting and penetrating agent F, spaonin powder, silkworm excrement or the soapberry powder.
Described filler is selected from one or more in kaolin, diatomite, bentonite, attapulgite, White Carbon black, starch or the precipitated calcium carbonate.
Material described above all is to well known to a person skilled in the art material, can buy by market.
Herbicidal composition provided by the invention is used for the weeds such as control wheat paddock, garlic field barnyard grass, lady's-grass, green foxtail, moleplant seed, eleusine indica, kitchen garden, clearvers, amaranth, lamb's-quarters, piemarker, black nightshade, cyperus iria, difformed galingale herb, and can reduce the application dosage of each active ingredient, reduce cost, reduce and pollute.
Beneficial effect of the present invention is: 1, the Herbicidal combinations synergistic effect is obvious, and drug effect significantly improves; 2, the Herbicidal combinations drug effect improves, and the field consumption of active ingredient descends, and has reduced production and use cost, reduces residue of pesticide and environmental pollution; 3, Herbicidal combinations is comprised of the active ingredient of different mechanism of action, and action site increases, and is conducive to overcome and delay the generation of herbicide resistance, is the important means of integrated control weeds in field.
