Abstract
The invention relates to a herbicide prepared by binary complex formulation of pendimetalin and oxyfluorfen, and the herbicide is composed of the following ingredients by weight: 33% of the pendimethalin, 5% of the oxyfluorfen, 12% of a synergistic agent, 15% of an emulsifier and 35% of a solvent. The herbicide solves the problems that herbicides in the prior art are not wide in used crops and less in weed killing species, is a high efficient, high-speed contact-killing broad-spectrum herbicide, can control annual weeds, can completely achieve effective control of harm of weed communities in fields by one time of herbicide application, can realize no weed in the whole growth period of crops, is safe to the crops, and has no adverse effects on afterreap crops, the application amount of the herbicide in each mu of field is 24-36g, and the cost of application is reduced by 55 to 42% compared with single use of the pendimethalin and oxyfluorfen.
Description
Technical field
What the present invention relates to is a kind of weed killer herbicide, relates in particular to the weed killer herbicide that a kind of binary built that comprises pendimethalin and Oxyfluorfen becomes.
Background technology
Peanut Fields is because of the general underproduction 5% to 10% of crop smothering, and serious field can reach 15% to 20%, even more.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.Along with the development of agricultural cience and farming techniques, one of the applying as saving of labor, save time of chemical herbicide, cost-effective strong well stimulation.
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 and kill the problems of whole weeds, and the weed killer herbicide that provides a kind of pendimethalin and Oxyfluorfen binary built to make expands herbicide and composes to reach, the object harmless to crop.
The weed killer herbicide that a kind of pendimethalin of the present invention and Oxyfluorfen binary built are made, is grouped into by the one-tenth of following mass percent: pendimethalin 33%, Oxyfluorfen 5%, synergist 12%, emulsifier 15%, solvent 35%.
Described synergist is the pesticide synergistic agent (Silwet) 625 containing Tea Saponin; Described emulsifier is castor oil polyoxyethylene ether 0206B; Described solvent is dimethylbenzene.
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 death.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 enter in plant corpus by coleoptile, mesocotyl, less through root absorption, and there is denier upwards to transport by root the leaf portion that enters, 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.
The invention has the beneficial effects as follows: the weed killer herbicide that a kind of pendimethalin and Oxyfluorfen binary built are made, having solved existing weed killer herbicide uses crop not wide, the disadvantage that weeding kind is few, for one is efficient, high speed contact killing type broad-spectrum herbicide, 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, commodity dose 24-36g for mu, dispenser cost is than pendimethalin and the low 55-42% of the single use of Oxyfluorfen.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
Embodiment 1
Get 33 grams of pendimethalins and add 20 milliliters of dimethylbenzene, stirring and dissolving; Get 5 grams of Oxyfluorfens and add 5 milliliters of dimethylbenzene, stirring and dissolving; Two kinds of solution are mixed, add 12 grams of pesticide synergistic agents (Silwet) 625 containing Tea Saponin, 15 grams of emulsifier castor oil polyoxyethylene ether 0206B, stir 15 minutes, 10 grams of dimethylbenzene that add surplus are made into 100 grams of gross masses, stir 20 minutes, leave standstill, filter, obtain the weed killer herbicide finished product that a kind of pendimethalin and Oxyfluorfen binary built are made.
Embodiment 2
The weed killer herbicide using method that a kind of pendimethalin of the present invention and Oxyfluorfen binary built are made:
Dispenser before seedling after Wheat Sowing, mu is used this product 24-36g, is watered 65 kilograms and is sprayed on soil table, to firm unearthed seedling safety, this product this product 24-36g for dispenser mu after seedling, be watered 45 kilograms of even spraying, can utterly destroy weeds in field, 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, holding effect can reach 35-55 days.
