Description

A kind of Herbicidal composition for paddy fields containing prosulfocarb and isoproturon
Technical field
The invention belongs to agricultural technology field, relate to a kind of Herbicidal combinations with synergistic function, being specifically related to a kind of Herbicidal composition for paddy fields for preventing and kill off paddy field grassy weed, sedge weed and broadleaved herb weeds.
Background technology
Prosulfocarb (prosulfocarb), chemical name is S-benzyl dipropyl thiocarbamate, is thiocarbamates selectivity inner sucting conduction type soil processing herbicide.Can susceptibility grassy weed seedling; symptom by thiocarbamates compound harm is seedling is bottle green, plant distortion; suppress the growth of seedling and root; and stop leaf from bud scale out; for the plant with the above true leaf of 4-5 leaf; meristematic tissue and around there is severe necrosis; soil treatment experimental study shows; " degree of depth " protective effect is depended on to the selectivity of dispenser before gramineous crop bud; analysis result and bioassay results show; because the leaching of prosulfocarb is low, therefore to prevent from touching with gramineous crop bud grafting in soil.
Prosulfocarb belongs to thiocarbamate herbicide, can be used for transplanted rice field, the weeding of live field, can effectively prevent and kill off grassy weed, sedge weed and broad leaved weed, as grass family Echinochloa, Sprangletop, Ma Tang genus, setaria, Paspalum, eleusine indica etc.; Annual and perennial nutgrass flatsedge is as Cyperus, Eleocharis, genus fimbristylis and firefly Lin, and broad leaved weed belongs to as ludwigia, Sagittaria, field grass genus, Pontederiaceae, spends Lin's genus and Drilgrass etc., has special efficacy especially to Monochoria vaginalis.But in actual applications only to the effect of closing down of grass-seed in soil obviously, and it is poor to the grassy weed preventive effect of being unearthed, due to paddy field weed seeding stage disunity, administration time is difficult to grasp, in addition the term of validity of medication is relatively shorter again, therefore medication generally needs 2 times, and each medication (effective dose) is 1200 ~ 3600 grams/ha.
Isoproturon (Isoproturon), chemistry 1,1-dimethyl-3-(4-isopropyl phenyl) urea by name, before belonging to substituted urea class selectivity bud, post-emergence herbicide.Primarily of weeds root absorption, cauline leaf absorbs few, is upwards transmitted to blade tip and leaf margin, plays a role in green cell in conduit with moisture.It is the inhibitor of photosynthesis electron transmission, disturb photosynthetic carrying out, can not release oxygen and carbon dioxide under light illumination, organic matter generates and stops, susceptible weeds is withered because of hungry, and drug resistance crop has selectivity with susceptible weeds because the absorption to medicament, conduction and accretion rate are different.Isoproturon is because of potential difference with to seed sprouting and root avirulence in soil, and after the nutrient depletion only stored in seed, susceptible weeds is just dead.Isoproturon is degraded by microorganisms in soil, and in water, solvability is high, easy leaching, and in soil, the half life period is about 20 days.
Isoproturon is mainly used in the crop such as wheat, barley field at present and prevents and kill off annual gramineous weed and part broadleaved herb.
Paddy field weed has developed into a huge plant community, and paddy field weed group is by absorbing in a large number light, soil nutrient etc. and rob, and severe weakness paddy growth situation, has a strong impact on yield and quality of rice.Current paddy field weed kind is many, existing grassy weed, has again the crop smotherings such as sedge weed and other broad leaved weeds etc., particularly grass family moleplant seed, barnyard grass, lady's-grass and broad leaved weed Monochoria vaginalis serious.The crop smothering emergence period is long, using chemical herbicide is the most effective means in preventing and controlling weed in rice field, but the long-term ground of high dose continuously uses kind and the single chemical herbicide of the mode of action, easily cause that residual, the rice quality of weed killer herbicide decline, environmental pollution and the negative effect such as weeds resistance and resistance development, turn increase drug cost.
