Abstract
An agricultural phytocide composition suitable for the most grasses, broadleaf weeds, and part of perennial weeds is prepared from three main components: oxadiazone, ethoxalylamine and ethoxyoxalylether in a ratio of (1-2):(2-4):(1:2), together with emulsifier (the mixture of AASEA60 and 8209) and solvent (toluene or xylene). It features high effect, broad spectrum and improvement of soil.
Description
The invention belongs to farm weeding preparation technique field.
Farmland medicine weeding must be selected weeding pesticide at the kind of grass, and the different living weeds kind in farmland of crop also is not quite similar.In addition, select weed killer herbicide also will consider the wherein accretion rate of effective ingredient in certain crop field soil, metabolism easily produces poisoning to second stubble crop too slowly.It is careless effective that day herbaceous weed research 1985.30 (4) 278-283 have reported that Acetochlor kills, and removes then DeGrain of broad leaved weed and sedge weed.It is the ternary built preparation of Acetochlor, click ethyl methyl, metsulfuron-methyl that CN1104847A discloses effective ingredient, is mainly used in paddy field weeding; It is the suspended emulsion of Acetochlor and s-triazine that CN1076077A discloses effective ingredient, is mainly used in cornfield weeding.Not seeing so far has the weed killer herbicide that is exclusively used in the garlic field openly to report.After garlic was carried out plastic film mulching cultivation, surface temperature height, high humidity helped weeds propagation and widespread, and the artificial weeding difficulty causes crop smothering seriously to take place.
The object of the present invention is to provide a kind of to the specific ternary compound herbicide of garlic field weeding.
The present invention selects for use oxadiazon, Acetochlor, Oxyfluorfen to make the ternary built preparation, its effective ingredient weight ratio is (1-2): (2-4): (1-2), select the compound of emulsifier AASEA60 and 8209 arbitrary proportions for use, solvent for use is one of toluene, dimethylbenzene, effective component content is the 25-50% percentage by weight, emulsifier content 5-15% percentage by weight, solvent 30-50% percentage by weight.
Above-mentioned composition is good with the effective ingredient weight ratio at 1: 2: 1.
With above-mentioned each component in proportion at normal temperatures and pressures the dissolving be mixed into uniform missible oil, be product of the present invention.
Oxadiazon, chemical name are 5-tertiary butyl-3-(2,4-two fluoro-5-o-phenyl-isopropyls)-1,3, and 4-oxadiazoline-2-ketone is a kind of selectivity earth inorganic agent, and it is long to kill the wide term of validity of careless scope, use cost height separately, and metabolism is slower in soil; Acetochlor, chemistry 2 '-ethyl-6 ' by name-methyl-N-(ethoxymethyl)-2-chloro acetanilide is a processing soil treatment agent before a kind of selectivity bud, and is good but broad leaved weed is prevented heterodyne to the grassy weed preventive effect; Oxyfluorfen, chemistry 2-chloro-1-(3-ethyoxyl-4-nitrophenoxy) by name-4-trifluoromethylbenzene is a kind of tagging property processing soil treatment agent, and is active high, good to the broad leaved weed preventive effect.The Emulsionable herbicides that the present invention selects above-mentioned three kinds of components to make as effective ingredient has obtained unexpected good effect in garlic field weeding practice, said composition is planted living grassy weed and broad leaved weed to the overwhelming majority, and part perennial weed preventive effect is remarkable.Composition in ratio of the present invention is made not only can enlarge the careless scope of killing, and improves drug effect, and can alleviate poisoning, improves soil condition, reduces the control cost.Weed killer herbicide of the present invention in the Yutai, Shandong, 5000 mu of ground demonstrations such as Gao He, king be big, to the about 85-92% of weeds preventive effect, save than artificial weeding mu and to drop into 45 yuan, mu increases 17 kilograms in the head of garlic, 11 kilograms of garlic shoots mu increase 70 yuan of net earnings.Relevant garlic field test determination data are listed following table in.
