Abstract
The invention relates to a composite herbicide containing pendimethalin, oxyfluorfen and acetochlor. The composite herbicide is composed of the following ingredients by the mass percentage: 30% of pendimethalin, 4% of oxyfluorfen, 10% of acetochlor, 5% of a synergistic agent, 11% of an emulsifier, and 40% of a solvent. The herbicide solves the disadvantages that conventional herbicides are not wide in applied crops and have not many weeding species, is the high-efficiency broad-spectrum herbicide, can prevent and remove annual weeds, can completely achieve effective control of harm of weed communities in fields with one time application, realizes no crop smothering during a crop whole growth period, is safe to crops, and has no any adverse effect on later crops.
Description
Technical field
The present invention relates to a kind of weed killer herbicide, especially a kind of containing pendimethalin, Oxyfluorfen and Acetochlor compound herbicide.
Background technology
Pendimethalin is that before selectivity bud, after bud, upland field soil is processed weed killer herbicide; Oxyfluorfen is a kind of contact killing type weed killer herbicide, brings into play herbicide effect in the situation that having light, and before bud and after bud, application effect is best in early days.Acetochlor is amide-type selectivity preemergence herbicide, dry crop is prevented and kill off to annual weed effective.But three kinds of single uses of single dose, a dispenser all can not realize crop time of infertility without crop smothering.
Summary of the invention
The object of the invention is intended to solve that above-mentioned weed killer herbicide exists can not reach a drug crop time of infertility without the problem of crop smothering, provides a kind of containing pendimethalin, Oxyfluorfen and Acetochlor compound herbicide, to reach, expands herbicide spectrum, the object harmless to crop.
The present invention is realized by following technical scheme: a kind of containing pendimethalin, Oxyfluorfen and Acetochlor compound herbicide, by the one-tenth of following mass percent, be grouped into: pendimethalin 30%, Oxyfluorfen 4%, Acetochlor 10%, synergist 5%, emulsifier 11%, solvent 40%.
Described synergist is the pesticide synergistic agent 625 containing Tea Saponin; Described emulsifier is castor oil polyoxyethylene ether 0206B; Described solvent is acetone or alcohol.
Pendimethalin is that before selectivity bud, after bud, upland field soil is processed weed killer herbicide.Weeds absorb medicament by the young shoot of sprouting, and enter medicament and tubulin binding in plant corpus, suppress the mitosis of plant cell, thereby cause weeds dead.Be widely used in the various crop field weedings such as corn, soybean, peanut, cotton, direct-seeding dry rice, potato, tobacco, vegetables, prevent and kill off annual gramineous weed, part broad leaved weed and nutgrass flatsedge.As barnyard grass, lady's-grass, green foxtail, moleplant seed, eleusine indica, kitchen garden, amaranth, lamb's-quarters, piemarker, black nightshade, cyperus iria, difformed galingale herb etc.Preventive effect to grassy weed is better than broad leaved weed.
Oxyfluorfen is contact killing type weed killer herbicide, in the situation that having light, bring into play its activity of weeding, mainly by coleoptile, mesocotyl, enter in plant corpus, less through root absorption, and there is denier to make progress and transport the leaf portion that enters by root, be used for before cotton, round onions, peanut, soybean, beet, fruit tree and vegetable fields bud, after bud, use and prevent and kill off barnyard grass, sesbania, downy brome, green foxtail, datura, quackgrass, artemisiifolia, thorn chrysanthemum sth. made by twisting, piemarker, charlock unifacial leaf and broad leaved weed, its very anti-leaching, can be made into missible oil and uses.Can prevent and kill off unifacial leaf and the broad leaved weed of transplanting rice, soybean, corn, cotton, peanut, sugarcane, vineyard, orchard, vegetable fields and forest nursery.Dryland rice dispenser can be mixed with butachlor; In dispensers such as soybean, peanut, Cotton Fields, can be mixed with alachlor, trefanocide etc.; Locate dispenser in orchard etc., can be mixed with paraquat, glyphosate.
Acetochlor is selectivity bud pre-treatment weed killer herbicide, mainly the hypocotyl by monocotyledonous coleoptile or dicotyledon absorbs, and absorbs backward upper conduction, mainly by impede protein matter, synthesizes and Cell growth inhibition, weeds young shoot, young root growth are stopped, so dead.The energy force rate broad leaved weed that grassy weed absorbs Acetochlor is strong, so prevent and kill off the effect of grassy weed, is better than broad leaved weed.
The invention has the beneficial effects as follows: a kind of containing pendimethalin, Oxyfluorfen and Acetochlor compound herbicide, having solved existing weed killer herbicide uses crop not wide, the disadvantage that weeding kind is few, for a kind of high-efficiency broad spectrum weed killer herbicide, prevent and kill off annual weed, a dispenser can reach the harm of effective control field weed community completely, realizes crop time of infertility without crop smothering, and to crop safety, to succession crop without any harmful effect.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
Embodiment 1
Get 30 grams of pendimethalins and add 20 milliliters of ethanol (or acetone), stirring and dissolving; Get 4 grams of Oxyfluorfens and add 5 milliliters of ethanol (or acetone), stirring and dissolving; 10 grams of Acetochlors add 10 milliliters of ethanol (or acetone), stirring and dissolving; Three kinds of solution are mixed, add 5 grams containing the pesticide synergistic agent (Silwet) 625 of Tea Saponin, 11 grams of emulsifier castor oil polyoxyethylene ether 0206B, stir 15 minutes, the ethanol (or acetone) that adds surplus is made into 100 grams of gross masses, stirs 20 minutes, standing, filter, obtain the clever Oxyfluorfen Acetochlor of 44% first penta compound herbicide finished product.
Embodiment 2
Get the weed killer herbicide finished product 400g that embodiment 1 makes, and be watered after 40kg, after broadcasting, the crops such as soybean, peanut, garlic, cotton carry out soil spraying before seedling, prevent and kill off annual weed, a dispenser can reach effective control field weed community harm completely, realize crop time of infertility without crop smothering, and to crop safety, to succession crop without any harmful effect.Dispenser cost is than pendimethalin, Oxyfluorfen and the low 25%-39% of Acetochlor single administration.
Claims (2)
