Abstract
A granular herbicide is prepared from nicosulfuron (1-85 wt.%),adhesive (0.5-11), stabilizer (0.2-15), surfactant (0.5-15), disintegrant (0.5-10) and filler (rest). Its advantages are broad spectrum, quickly taking its high effect, and no residue.
Description
Technical field: the present invention relates to a kind of highy potent herbicide that is used for corn field, a kind of herbicide granule that contains nicosulfuron of more specifically saying so.
Background technology: the preparation of nicosulfuron mainly contains wetting powder, the low concentration colloidal suspending agent at present.Because wetting powder easily lumps in storage process, easily produce the dust drift in production and the use, contaminated environment, especially nicosulfuron is a highy potent herbicide, dust drift very easily causes the large tracts of land poisoning, seriously restricts the popularization and the use of this product, though and the low concentration colloidal suspending agent has solved the problem that the nicosulfuron wetting powder exists, but, thereby increase packing and cost of transportation because concentration is low.
Summary of the invention: technical problem to be solved by this invention is: a kind of efficient, quick-acting, low-residual, formulation advanced person, herbicide granule nicosulfuron and preparation method thereof safe in utilization are provided.Its technical scheme is: a kind of herbicide granule nicosulfuron is characterized in that its raw material components and percentage by weight thereof:
Nicosulfuron 1～85
Binding agent 0.5～11
Stabilizing agent 0.2～15
Surfactant 0.5～15
Disintegrant 0.5～10
Filler 0/ or complement to 100.
Described nicosulfuron can be selected the former medicine of nicosulfuron for use;
Described binding agent is selected a kind of or several mixing in polyvinyl alcohol, polyvinyl acetate, dextrin, starch, the gum Arabic for use;
Described stabilizing agent is selected phosphorous acid or triphenyl phosphate for use;
Described surfactant is sodium phosphate trimer, lignosulfonates, NNO, polyoxyethylene poly-oxygen propylene aether block copolymer, rope uncle SOPA, diffusion agent N O, dispersing agent MF, neopelex, draw back in powder, penetrant t, penetrating agent JFC, lauryl alcohol polyethylene glycol oxide base ether sodium sulfate, polysorbate60, the basic phenol polyethenoxy base of suffering (ninth of the ten Heavenly Stems) ether one or more;
Described disintegrant is one or more mixing disintegrants in ammonium sulfate, sodium chloride, magnesium chloride, aluminium chloride, urea, the bentonite;
Described filler is one or more mixed fillers in white carbon, potter's clay, attapulgite, precipitated calcium carbonate sodium sulphate, the talcum powder.
Its preparation method is:
Active ingredient nicosulfuron, surfactant, filler, stabilizing agent, disintegrant, binding agent, water are mixed, make female powder;
Female powder is dropped into the Squeezinggranulator granulation;
With the granule made after drying, sieving promptly gets this granule.
Good effect of the present invention is:
Through carrying out herbicidal effect and safety testing shows: its 75% water dispersible granule of nicosulfuron 3g, 4g, 5g, 8g/667m at corn field
2Weeds such as the green foxtail in the corn field, barnyard grass grass, nutgrass flatsedge, fennel fiber crops are handled, 10d behind medicine, its strain preventive effect is respectively 65.7%, 72.0%, 76.5%, 81.6%; 30d behind the medicine, its strain preventive effect is respectively 87.7%, 91.0%, 92.7%, 96.3%; And it is to the advantage weeds: the integrated control effect of green foxtail, barnyard grass grass, nutgrass flatsedge is good, is better than piemarker (-75% water dispersible granule of nicosulfuron cornfield weeding effect and the safety testing of please seeing Appendix); Having the wider grass that kills composes.
The present invention is granule on preparation, and adopts international advanced pesticide slow-release technology, therefore can guarantee that the product lasting period is longer; Be easy to transportation; Use safer, convenient; Simultaneously, because of its not with an organic solvent, so environmentally friendly.Test shows: 75% water dispersible granule of nicosulfuron 2-3 leaf phase cauline leaf behind maize seedling is handled, and to corn growth and solid having no adverse effects, safety is good.
Manufacturing approach craft of the present invention is simple, gets final product granulation after mixing, and equipment volume is little, can produce continuously in confined conditions, can realize cleaner production, has removed the poisoning hidden danger that the dust drift is brought.
