Abstract
The invention discloses a ternary compound special herbicide for vegetables. The ternary compound special herbicide is obtained by the following steps: dissolving trifluralin, bentazone and haloxyfop-methyl into a solvent, and adding a surfactant, a dispersant, a viscosity regulating agent and a carrier filler. The special herbicide for the vegetables comprises the following components in parts by weight: 10-30 parts of trifluralin, 10-20 parts of bentazone, 1-30 parts of haloxyfop-methyl, 30-80 parts of the solvent, 5-20 parts of the surfactant, 1-12 parts of the dispersant, 1-10 parts of the viscosity regulating agent and 20-40 parts of the carrier filler. The ternary compound special herbicide for the vegetables has a very good effect on grass and broad leaf species, has low toxicity, few residues, wide herbicide controlling spectrum and remarkable effect, and can provide a good growth condition for the vegetables.
Description
Technical field:
The invention belongs to technical field of pesticide, particularly a kind of tri compound vegetables herbicides special.
Background technology:
Weeds are troubles in the production of vegetables, if all manually the weed a garden effect that both wasted time and energy of dependence is not good yet, therefore usually carry out weeding by weed killer herbicide.
Weed killer herbicide has go out natural disposition and contact killing type of inner sucting conduction type selectivity, contact killing type selectivity, inner sucting conduction type to go out natural disposition four kinds.Inner sucting conduction type refers to that weed killer herbicide is sprayed on certain part of vegetables, other positions of vegetables can be transmitted to, contact killing type refers to that weed killer herbicide is sprayed on certain part of vegetables, other positions of vegetables can not be transmitted to, selectivity refers to that weed killer herbicide only can kill one or class weeds in certain circumstances and not injure vegetables, and natural disposition of going out refers to that weed killer herbicide has injury effect to weeds and vegetables.Therefore vegetable fields will select the weed killer herbicide of conduction type difference, preferably selects contact killing type selective herbicide.In addition, also need to possess drug effect phase short, the feature such as the longevity of residure is short, hypotoxicity for the weed killer herbicide of vegetable field.
Conventional vegetables have multiple with weed killer herbicide, soil treatment medicament has benthiocarb, drag-line, propachlor, trefanocide, drag-line, Mo 9 granular and executes field benefit etc., and cauline leaf treatment agent has quizalofopethyl, surely kills, Sethoxydin and catch Cao Jing etc.Because the kind of vegetables and variety protection many, vegetative period is short again, cropping index is high, and the production cycle contains to being in weeds the phase of sending out, and soil fertilizer can encourage the growth of weeds, various in style because of weed killer herbicide, so need careful use, slightly improper, poisoning will be caused and remain, harm humans healthy, the circulation affecting vegetables is produced.
Summary of the invention:
The object of this invention is to provide a kind of tri compound vegetables herbicides special, adopt trefanocide, Bentazon and the efficient fluorine tri compound vegetables herbicides special as primary raw material prepared cleverer in first standing grain, the method weed killer herbicide toxicity is low, residual few, broad weed-killing spectrum, Be very effective.
Object of the present invention is achieved through the following technical solutions:
A kind of tri compound vegetables herbicides special, with parts by weight, comprise following component:
Trefanocide 10-30 part, Bentazon 10-20 part, fluorine combination cleverer in first standing grain 1-30 part,
Solvent 30-80 part, surfactant 5-20 part, dispersant 1-12 part,
Viscosity modifier 1-10 part, carrier filler 20-40 part.
Preferred as technique scheme, a kind of tri compound vegetables herbicides special, with parts by weight, comprises following component:
Trefanocide 25 parts, Bentazon 19 parts, fluorine combination 14 part cleverer in first standing grain,
Solvent 65 parts, 10 parts, surfactant, dispersant 6 parts,
Viscosity modifier 5 parts, carrier filler 30 parts.
Preferred as technique scheme, described solvent is water, ethanol or ethyl acetate.
Preferred as technique scheme, described surfactant is alkylbenzene naphthenic acid salt, alkyl sulfate or paregal O.
Preferred as technique scheme, described dispersant is calcium lignosulfonate, sodium lignin sulfonate or white carbon.
Preferred as technique scheme, described viscosity modifier is carboxymethyl cellulose, xanthans or polyvinyl alcohol.
Preferred as technique scheme, described carrier filler is kaolin, bentonite or talcum powder.
For better solving the problem, present invention also offers the preparation method of this tri compound vegetables herbicides special, concrete steps are:
(1) Bentazon and fluorine combination cleverer in first standing grain are poured in solvent, after dissolving completely, add trefanocide, stir, obtain mixed solution;
(2) mixed solution that step (2) obtains is warming up to 30-40 DEG C, adds surfactant, dispersant, viscosity modifier and carrier filler successively, ultrasonic agitation 5-30min, cooling, obtains tri compound vegetables herbicides special.
Beneficial effect of the present invention is: these vegetables are with comprising the combination cleverer in first standing grain of three kinds of main component trefanocide, Bentazon and fluorine in herbicide, wherein, the anti-annual gramineous weed of trefanocide and part broadleaf weed, the anti-grassy weed Be very effective of Bentazon, fluorine combination cleverer in first standing grain anti-broad-leaved section weeds are remarkable, three kinds of raw materials all possess the characteristic of low toxicity and low residue, therefore three kinds of raw material mixing are made its combination among the strong ones, while increase herbicidal effect, increase herbicide spectrum, also can not to pollution vegetables and soil, to human body and environment all pollution-free.
