Abstract
The invention discloses a weeding agent for soybean field, solves the problem of poor effect of a weeding agent in the prior art, and is characterized by consisting of fomesafen, acetochlor, quizalofop-p-ethyl or haloxyfop-methyl and water which are mixed together. The weeding agent disclosed by the invention can be used for comprehensively controlling annual broadleaf weeds and gramineous weeds in the soybean field; particularly, the effect on common dodder weeds in the soybean field is obvious; the weeding agent kills the weeds without rebounding; the harm of the weeds can be eradicated basically by one time of the pesticide application without affecting the output of the soybean; and the weeding agent saves the labor, the time and the cost.
Description
Technical field
The present invention relates to a kind of complex weedicide, relate to or rather a kind of weed killer herbicide for the Soybean Field management of weeds.
Background technology
The weed killer herbicide that is widely used at present Soybean Field is a kind of single dose often, kills the weeds spectrum more single, can not effectively control the Soybean Field crop smothering in whole vegetative period, and safety is poor.Particularly the grass of the dodder in Soybean Field, for annual parasitic herbaceous plant, thread, be attached on grogs, the other end forms thread Tu silk, aloft rotation, encounter beans and just be wound around on it, form sucker in the contact position, draw nutrient and the moisture of beans, and the continuous branch elongation of stem forms sucker, constantly expand to surrounding again, when serious, whole strain beans are covered with dodder, make a beans undergrowth, even cause the death of complete stool beans, sometimes have to connect beans and pull out together.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art provides a kind of weed killer herbicide for Soybean Field, and preparation is simple, herbicidal effect is obvious, does not stay grass roots, has wide spectrum, efficient advantage, removes the dodder grass significantly.
The invention is characterized in by former dose of liquid and water to form, former dose of described liquid is 40-70 part by weight, and water is 15000-30000 part; Former dose of described liquid is comprised of A, B component by weight: described A component is comprised of fomesafen 10-30 part, 50% Acetochlor 10-30 part of 25%, described B component is Quizalotop-ethyl 15-30 part, be perhaps 10.8% haloxyfop-P-methyl 10-30 part, perhaps formed by Quizalotop-ethyl 8-15 part and 10.8% haloxyfop-P-methyl 5-15 part; Described Quizalotop-ethyl content is 8.8% or 10.8%.
The preparation method:
By above-mentioned part by weight, fomesafen, Acetochlor, Quizalotop-ethyl or haloxyfop-P-methyl are mixed, former dose of liquid stirs to get; Former dose of liquid and water are mixed make water soluble preparation and get final product.
Described fomesafen; chemical name: 5-(2-chlorine a; a, a-three fluoro-are to toloxyl)-N-mesyl-1-nitre benzamide; a kind of soybean, Peanut Fields herbicide after seedling with high selectivity; can effectively prevent and kill off soybean, Peanut Fields broad leaved weed, grassy weed is also had certain preventive effect.Can be absorbed by weeds root leaf, make its rapid withered and yellow death, after the spray medicine, 4-6 hour chance rain does not affect drug effect, to soybean safety.
Described Acetochlor, chemical name: 2-ethyl-6 methyl--N-ethoxyl methyl-alpha-chloro acetanil is prevented and kill off the broad leaved weed that object is mainly annual gramineous weed and part small-sized seed.
Described Quizalotop-ethyl, chemical name: (R)-2-[4-(6-chloroquinoxalin-2-yloxy) phenoxy group] ethyl propionate, controlling object: annual and perennial grassy weed.
Described haloxyfop-P-methyl is a kind of selective herbicide, is used for various broad leaf crop Tanakas and prevents and kill off various grassy weeds.Especially the perennial obstinate grassy weeds such as reed, cogongrass, Bermuda grass had remarkable preventive effect, to the broad leaf crop high safety.
Using method: the dispenser date in 10-20 days, uses with atomizer spray from soybean planting.The soybean seedling age about 10 days, large bean seedlings leaf hour can be the use that reduces by half of former dose of liquid.Generally afternoon, pesticide supplying effect was better.
As shown from the above technical solution, the present invention is using after large bean seedlings several single herbicides are composite, can prevent and treat annual broadleaf weed and the grassy weed of Soybean Field comprehensively, as wheat seedlings, flat grass, acalypha copperleaf, rough rice grass, kitchen garden, emarginate amaranth herb or seed, sachet grass, green foxtail etc., particularly remarkable to the common dodder grass effect of Soybean Field, kill weeds and do not rebound, but dispenser uproot weeds harm substantially, and do not affect the output of soybean, the saving of labor, save time, save money.
Embodiment
Embodiment 1
Get 25% fomesafen 18g, 50% Acetochlor 14g, 8.8% Quizalotop-ethyl 20g mixes, former dose of liquid stirs to get; Former dose of liquid is mixed with water 20000g make water soluble preparation.
Application method: from soybean planting 10 days-20 days, first add a small amount of water in sprayer, put into former dose of above-mentioned liquid, and then add the water of surplus, stirring can be sprayed on beans field and bean seedlings.
Herbicidal effect: the weeds such as the common flat grass in ground of annual herb plant such as Soybean Field, wheat seedlings, acalypha copperleaf, rough rice grass, kitchen garden, emarginate amaranth herb or seed, sachet grass, green foxtail, particularly dodder grass until all do not have during the harvesting soybean, has reached preventive effect.Sometimes due to spraying not thoroughly, comprehensively, when weeds appear in the part, perhaps have when indivedual beans are upper is wound around the dodder grass, available above-mentioned preparation Direct spraying is on weeds or beans, it is withered death that general 2-4 days dodder grass wait weeds.
