Description

A kind of Herbicidal composition for paddy fields containing prosulfocarb and isoproturon
Technical field
The invention belongs to agricultural technology field, is related to a kind of Herbicidal combinations with synergistic function, and in particular to A kind of Herbicidal composition for paddy fields for being used to prevent and kill off rice terrace grassy weed, sedge weed and broadleaved herb weeds.
Background technology
Prosulfocarb (prosulfocarb), chemical name are S- benzyl dipropyl thiocarbamates, are sulfo-amino Formate ester selectivity inner sucting conduction type soil processing herbicide.Can sensitiveness grassy weed seedling, by thiocarbamic acid The symptom of ester type compound harm is that seedling is dark green, plant distortion, suppresses the growth of seedling and root, and prevent leaf from bud scale Out, for the plant with 4-5 leaf above true leaves, separate living tissue and its around there is severe necrosis, soil treatment experiment Result of study shows, " depth " protective effect, analysis result and biology are depended on to the selectivity of dispenser before gramineous crop bud Measurement result shows, since the leaching of prosulfocarb is low, therefore to prevent from contacting with gramineous crop bud in soil.
Prosulfocarb category thiocarbamate herbicide, available for transplanted rice field, live field weeding, can effectively prevent and kill off Grassy weed, sedge weed and broad leaved weed, as grass family Echinochloa, Sprangletop, Ma Tang categories, setaria, Paspalum, Eleusine indica etc.；Annual and perennial nutgrass flatsedge such as Cyperus, Eleocharis, genus fimbristylis and firefly Lin, broad leaved weed such as ludwigia, Sagittaria, the careless category in field, Pontederiaceae category, flower Lin category and Drilgrass etc., especially have special efficacy to Monochoria vaginalis.But in practical applications only To grass-seed in soil, the effect of closing down is obvious, and poor to unearthed grassy weed preventive effect, due to the paddy field weed seeding stage Disunity, administration time are difficult to grasp, and the term of validity of medication is opposite again shorter in addition, therefore medication generally requires 2 times, uses every time Medicine (effective dose) is 1200~3600 grams/ha.
Isoproturon (Isoproturon), entitled 1,1- dimethyl -3- (4- isopropyl phenyls) urea of chemistry, belongs to substituted urea class Before selective bud, post-emergence herbicide.Mainly absorbed by weeds root, cauline leaf absorbs less, and leaf is transmitted to upwards with moisture in conduit Point and leaf margin, play a role in green cell.It is the inhibitor of photosynthesis electron transmission, disturbs photosynthetic progress, Cannot release oxygen and carbon dioxide under light illumination, organic matter generation stops, and susceptible weeds are withered because hungry, drug resistance crop and Susceptible weeds have selectivity because the absorption to medicament, conduction and accretion rate are different.Isoproturon in the soil because of potential difference and Non-toxic to germination and root, susceptible weeds are just dead after the nutrient depletion only stored in seed.Isoproturon is in soil In be degraded by microorganisms, solubility is high in water, easy leaching, and half-life period is 20 days or so in the soil.
Isoproturon is currently used primarily in the crop fields such as wheat, barley and prevents and kill off annual gramineous weed and part broadleaved herb.
