Abstract
The invention provides a weeding combination for soybean, which belongs to peanut fields, and has good weeding effect and wide weeding range, and can delay the drug resistance of weeds, belonging to the technical field of herbicide. The technical points are as follows: active ingredients of the weeding combination is oxadiazon and flumioxazin, and the weight proportion of the two is 1:0.08-0.2. By adopting the combination of two herbicides, namely, the oxadiazon and the flumioxazin,for formulation, the weeding combination not only has obvious weeding effect and strong complementarity, and is safe for soybean and peanut, but also delays the drug resistance of the weeds, expands the weeding range, prolongs the efficacy-lasting period, reduces drug application times, and greatly lowers the cost; and one-time drug application can ensure that no weed harm exists in the whole growth season, therefore, not only the weeding procedure is simplified, the labor intensity is alleviated, and the obvious production increase effect is realized, and the prominent social benefits are outstanding.
Description
Technical field
The present invention relates to a kind of Herbicidal combinations, particularly a kind of soybean, peanut field weeding composition.
Technical background
Soybean, peanut are the main oil crop of China, and annual cultivated area is greatly about 1,200 ten thousand hectares, and along with the adjustment of the structure of agricultural production, cultivated area also has the trend that enlarges year by year.Because China is vast in territory, the natural conditions complexity, the difference of various crop-planting modes, cropping system and cultivation step, thus formed the weeds population of different monoids.Soybean, the medium crop smothering area of peanut all account for more than 53.4% of total cultivated area, lose soybean, peanut thus every year 5%～20%, even more than 30%.Along with the development of agricultural cience and farming techniques, one of the applying as the saving of labor, save time of chemical herbicide, cost-effective strong well stimulation.At present, soybean, peanut herbicide before seedling stage kind mainly are weed killer herbicides such as butachlor, Acetochlor.Because long-term the use causes weeds to develop immunity to drugs, variation has also taken place in weed community, and herbicidal effect descends year by year.In order to address these problems, need research and development in the production badly to soybean, peanut safety, to the new kind of the effective weed killer herbicide of weeds.
Evil humulone and flumioxazin all are the weed killer herbicides that has come into operation both at home and abroad.The Evil humulone, English general by name: Oxadiazon, chemical name are 5-tertiary butyl-3-(2,4-two chloro-5-o-phenyl-isopropyls)-1,3,4-oxadiazoline-2-ketone.The Evil humulone is a selectivity contact killing type weed killer herbicide.This agent absorbs through the weeds seedling, seedling is stopped growing, then perish.The main plant corpus ATP that suppresses forms.Light time competence exertion activity of weeding is arranged.Be suitable for paddy rice, also can be used for crops such as soybean, cotton and prevent and kill off annual gramineous weed and broad leaved weed.With soil treatment before the seedling is good.Flumioxazin, English general by name: flumioxazin belongs to cyclic imide class low toxicity herbicide.Flumioxazin is the weed killer herbicide that is absorbed by young shoot and blade, makes soil treatment and can effectively prevent and kill off 1 year livings broad leaved weed and part grassy weed, easily degrades in environment, to succession crop safety.Soybean, peanut have good drug resistance to it.Corn, wheat, barley, paddy rice have medium patience.The scope of application: be suitable for crop fields such as soybean, peanut, orchard and prevent and kill off 1 year living broad leaved weed and part grassy weed.
It is good to the purpose of this invention is to provide a kind of herbicidal effect, and broad weed-killing spectrum can delay the drug-fast soybean of weeds, peanut field weeding composition.
Its technical scheme is: a kind of soybean, peanut field weeding composition, it is characterized in that its active component Wei Evil humulone and flumioxazin, and the weight proportion of the two is 1: 0.08～0.2.
Soybean of the present invention, peanut field weeding composition, its Huo Cheng Fen Evil humulone and flumioxazin are equipped with insecticides adjuvant can become suitable soybean, peanut field directly to use according to the method processing and preparing of routine formulations such as missible oil, water dispersible granules or suspending agent.
Insecticides adjuvant comprises wetting agent and/or dispersant and/or solvent and/or spreader-sticker and/or cosolvent and/or solvent and/or bleeding agent and/or carrier.
Herbicidal combinations of the present invention has tangible advantage: Evil humulone and two kinds of mixture of herbicides of flumioxazin, and not only herbicidal effect is remarkable, to soybean, peanut safety, with strong complementarity, and delayed the pesticide resistance of weeds, enlarged and killed the grass spectrum, improved the lasting period, reduced the medication number of times, also reduced cost significantly, a drug is the no weeds harm of controlled whole growth season joint, both simplified the weeding program, alleviated labour intensity, effect of increasing production is also very remarkable, and social benefit is outstanding.
Embodiment
Embodiment 1.35% Evil humulone flumioxazin water dispersible granules: Evil humulone 32.5%, flumioxazin 2.5%, D-425 7%, and EFW 2%, ammonium sulfate 5%, polyethylene glycol 2%, kaolin supplies 100%.Adopt conventional method to make water dispersible granules.
Embodiment 2.25% Evil humulone flumioxazin suspending agent: Evil humulone 22.5%, flumioxazin 2.5%, Pluronic125 5.5%, propane diols 3%, xanthans 0.8%, water supplies 100%.Adopt conventional method to make suspending agent.
Embodiment 3.28% Evil humulone flumioxazin missible oil: Evil humulone 25%, flumioxazin 3%, emulsifier 220110%, dimethylbenzene complements to 100%.Adopt conventional method to make missible oil.Its preventive effect is an example with the soybean weeding: before soybean is broadcast the back seedling, get 28% Evil humulone flumioxazin missible oil dosage 80,100,120ml/mu, convert water and spray for 40 kilograms/mu, 20,50 days and maturing stage range estimation soybean safety and weeds preventive effect, 20, survey all preventive effects in 50 days, the results are shown in subordinate list:
By range estimation, from the dispenser to the maturing stage, do not see symptom of chemical damage, to soybean safety.The preventive effect of weeds reached more than 95% in 20 days, reached more than 90% in 50 days, significantly was better than the preventive effect of two kinds of single agent.Along with the increase of dosage, preventive effect obviously strengthens, at soybean field 100ml/667m
2Can reach good herbicidal effect, a dispenser can be controlled the weeds in the crop whole growing, and second stubble crop is not had influence.
