Abstract
The invention relates to a Fenoxaprop.Flucarbazone composite herbicide, belonging to the technical field of pesticide and aiming to solve the technical problem of providing a Fenoxaprop.Flucarbazone composite herbicide for preventing and killing wheat field resistance grass family weeds. The technical key point is that the composite herbicide is prepared by the following raw materials and assistants in mass percentage: 0.1-90 of Fenoxaprop, 90-0.1 of Flucarbazone, 5-7 of dispersant, 1-3 of wetting agent, 3-5 of disintegrant, 2-3 of adhesive and balance of carrier. The inventive herbicide has obvious weeding effect on resistance grass family weeds, obviously superior to two single preparations and other composite preparations; meanwhile, the herbicide has broad weeding spectrum, can efficiently prevent and kill annual resistance grass family weeds without influencing the crops to be grown; the herbicide is environment-friendly and is an ideal herbicide for treating post-sprout stems and leaves of wheat at present.
Description
Technical field
The present invention relates to a kind of complex weedicide that cauline leaf is handled behind the wheat seedling, particularly a kind of fenoxaprop fluorine azoles sulphur composite herbicide of being used for.
Technical background
Wheat is one of staple food crop of northern China, and the long-term cultivated area of China is only second to the paddy rice cultivated area at more than 3,000 ten thousand hectares.Wheatland crop smothering area accounts for more than 30% of total cultivated area, and wherein serious injured area is more than 8%, and the general underproduction can be had no harvest when serious more than 15%.Therefore, the usage ratio of domestic wheat paddock weed killer herbicide almost reaches 100%, and its dosage is very big.The wheat paddock weeds are divided into broad leaved weed and grassy weed two classes.Wherein, the broad leaved weed ratio is easier to prevent and kill off, and grassy weed is difficult to prevent and kill off owing to belonging to grass family together with wheat.And because of using single weed killer herbicide to prevent and kill off grassy weed for many years, weeds have produced pesticide resistance, cause its large usage quantity, make wheat produce recessive poisoning and the underproduction easily, and also not too safe to succession crop.In addition, because the use of chemical herbicide for many years, variation has also taken place in the group of China wheat district weeds, originally northern wheat district grassy weed is based on wild oat, wheat district, south grassy weed is based on amur foxtail, Wang grass, and resistant weeds such as the hard grass of north and south Mai Qu, bromegrass, Annual Ryegrass, Triticum tauschii all generally take place now.China's wheat seedling rear defence has: fenoxaprop 6.9% aqueous emulsion, fenoxaprop 10% missible oil, grand 3% oil suspending agent of methyl two sulphurs, alkynes oxalic acid 15% wetting powder, grand 70% water dispersible granules of fluorine azoles sulphur etc. except that the main medicament of weed killer herbicide of grassy weed at present.According to experiment and field practical application, this several herbicides all can only be prevented and kill off a part of grassy weed wherein, and undesirable to other grassy weed effect.So just press for the weed killer herbicide that can prevent and kill off wheat paddock resistance grassy weed, neither influence the safety of succession crop, friendly to environment again weed killer herbicide, and this type of weed killer herbicide of China is seldom seen at present.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and can prevent and kill off wheat paddock resistance grassy weed, and succession crop is not had influence, environment amenable fenoxaprop fluorine azoles sulphur composite herbicide again.
Its technical scheme is: a kind of fenoxaprop fluorine azoles sulphur composite herbicide, it is characterized in that: it by the raw material of following quality percentage composition and auxiliary agent make that: fenoxaprop 0.1～90, fluorine azoles sulphur are grand 90～0.1, dispersant 5～7, wetting agent 1～3, disintegrant 3～5, adhesive 2～3, carrier complements to 100.
Above-mentioned raw materials and auxiliary agent promptly get wetting powder or water dispersible granules through fully mixing, comminution by gas stream, mixing, granulation, drying and screening.
Its technique effect is: by in Anhui, the field control effectiveness test in 2 years in ground such as Henan, Shandong, Jiangsu shows, in winter wheat 3 leaves～tillering stage, weeds 1～6 leaf does not wait the phase, adopt the present invention 25% fenoxaprop fluorine azoles sulphur composite herbicide WG 15,20,25,40 gram/mus, convert 40 kilograms/mu in water, winter wheat after the spring period of seedling establishment spray range estimation wheat safety of 15,45 days and maturing stage and weeds preventive effect, 15, surveyed all preventive effects in 45 days, result such as following table:
