Abstract
The invention relates to a herbicide for a paddy field. The herbicide composition comprises the following components in parts by weight: 20-30 parts of oxyfluorfen, 15-25 parts of acetochlor, 10-20 parts of vernolate, 15-25 parts of linuron, 10-20 parts of fatty acid glyceride, 25-35 parts of stearic acid and 45-55 parts of salad oil. The herbicide has the beneficial effects that the herbicide composition is mainly used for controlling weeds in the paddy field, has a good weeding effect and is capable of effectively removing target weeds; furthermore, the consumption and the application frequency of the herbicide can be reduced, and the pesticide effect lasting period of the herbicide is long.
Description
Technical field
The present invention relates to herbicidal composition, particularly a kind of weed killer herbicide for paddy field.
Background technology
Weed killer herbicide is in the market of a great variety, but most weed killer herbicide creates very large pollution to soil after use, changes soil structure, affects the mouthfeel of crop itself; And a lot of weed killer herbicide all can make seedling body itself sustain damage in use, affects its growth rate.
Oxyfluorfen is the fluorine-containing benzene ether-derivative herbicides succeeded in developing by Rhom and Hass of the U.S. in 1975, and its activity of weeding improves 5 ~ 10 times than corresponding nitrofen, is 16.32 times of benthiocarb.The scope of application is wide, broad weed-killing spectrum, and the lasting period is long, and mu consumption is few, active high, can use with multiple mixture of herbicides, expands herbicide spectrum, and raising drug effect is easy to use, both can bud pre-treatment, again can bud post processing, and toxicity is low.
Mesocotyl enters in plant corpus, less through root absorption, and has denier upwards to be transported by root to enter leaf portion.
For before cotton, round onions, peanut, soybean, beet, fruit tree and vegetable fields bud, use after bud and prevent and kill off barnyard grass, sesbania, downy brome, green foxtail, datura, quackgrass, artemisiifolia, thorn chrysanthemum sth. made by twisting, piemarker, charlock unifacial leaf and broad leaved weed.Its very anti-leaching.Can be made into missible oil to use.
Transplanting rice, soybean, corn, cotton, peanut, sugarcane, vineyard, orchard, the unifacial leaf of vegetable fields and forest nursery and broad leaved weed can be prevented and kill off.Dryland rice dispenser can be mixed with butachlor; In dispensers such as soybean, peanut, Cotton Fields, can be mixed with alachlor, trefanocide etc.; In place's dispensers such as orchards, can be mixed with paraquat, glyphosate.
Acetochlor: a kind of weed killer herbicide of extensive use.Being succeeded in developing in 1971 by About Monsanto Chemicals, is current one of most important weed killer herbicide kind in the world, is also one of maximum weed killer herbicide of current China usage amount.Acetochlor sterling is weak yellow liquid, and former medicine is because presenting peony containing impurity.Stable in properties, not volatile and photodissociation.Water insoluble, be soluble in organic solvent.Fusing point is greater than 0 DEG C, and vapour pressure is greater than 133.3pa, and boiling point is greater than 200 DEG C, not volatile and photodissociation.When 30 DEG C and the relative density of water be 1.11, the micro-223mg/l of the solvability in water.Be applicable to: corn, cotton, beans, peanut, potato, rape, garlic, tobacco, sunflower, castor-oil plant, shallot etc.Acetochlor is selectivity bud pre-treatment weed killer herbicide, hypocotyl mainly through monocotyledonous coleoptile or dicotyledon absorbs, and absorbs backward upper conduction, synthesizes and Cell growth inhibition mainly through hindering protein, weeds young shoot, young root are grown stop, so dead.The energy force rate broad leaved weed that grassy weed absorbs Acetochlor is strong, so the effect of preventing and kill off grassy weed is better than broad leaved weed.About the 45 days lasting period in soil of Acetochlor, mainly through microbial degradation, the mobility in soil is little, mainly remains in 0-3 cm layer of soil.
Vernolate, also known as defending agriculture, is a kind of dithiocarbamate herbicide.Former medicine is yellowish-brown transparent oily liquid, tool minimal irritation stink.In water, solvability is 90Mg/L (20 DEG C), dissolves in multiple organic solvent.Preparation is yellowish-brown liquid.Formulation is missible oil.Be mainly used in soybean, Peanut Fields prevent and kill off grass family, sedge weed and the sub-weeds of the double leaf such as the rhizome of nutgrass flatsedge, piemarker.Former medicine Oral Administration in Rats LD501500mg/kg.Vernolate oily liquids.Boiling point 140 DEG C (2.66kPa).Vapour pressure 4.5Pa when 25 DEG C.Relative density 0.954.Solvability when 20 DEG C in water is 90mg/L, is dissolved in organic solvent.Stable in properties.Rat acute LD50 of passing through mouth 1780mg/kg, Rabbits with Acute is through skin LD50>2955mg/kg.Preparation has missible oil and 5%, 10% granule.Weed killer herbicide.Reacted to generate or reacted by di-n-propylamine and carbonyl sulfide and dipropyl sulfate by dipropyl carbamyl chloride and propanethiol and generate.For preventing and kill off broad-leaved and the grassy weed of sprouting in soybean and Peanut Fields.Consumption 1.5 ~ 3.0kg/ha.
Soil treatment dithiocarbamate herbicide before selectivity bud, trade name defends agriculture (Vernam7-E), weed eradication is all.
The former pharmaceutically active ingredient content of performance is 96%, and outward appearance is yellowish-brown transparent oily liquid, has minimal irritation stink.Density 0.954 when 20 DEG C, boiling point 149-150 DEG C/3999.6 handkerchiefs, when 20 DEG C, in water, solvability is 90mg/l, dissolves in multiple organic solvent, pH7.0.Low toxicity.In test dose to animal without teratogenesis, mutagenesis, carcinogenesis.No abnormality seen in three-generation test of reproduction and delayed neurotoxicity test, very low to birds toxicity, quail bag per os LC50 is 12000mg/kg.To honeybee and natural enemy harmless.
Lorox is phenyl ureagroup herbicides, has Uptake and translocation and action of contace poison.Drug effect is high, but poor selectivity.To this product absorption affinity by force, therefore rich clay should be larger than sandy thin meagerly block consumption for soil clay particle and organic matter.Lorox to annual gramineous weed, as lady's-grass, green foxtail, gram, knotweed etc. has good preventive effect, is suitable for the field of vegetables application such as celery, pulse family field of vegetables, carrot, potato, green onion.
Chinese another name: 3-(3,4-dichlorophenyl)-l-methoxyl group-1-MU; 1-methoxyl group-1-methyl-3-(3,4-dichlorophenyl) urea; N-(3,4-dichlorophenyl)-N '-methoxyl group-N '-MU; Straight siron.
Lorox to annual gramineous weed, as lady's-grass, green foxtail, gram, knotweed etc. has good preventive effect, is suitable for the field of vegetables application such as celery, pulse family field of vegetables, carrot, potato, green onion.
