Abstract
The invention relates to a herbicide composition containing humic acid, fluazifop-P-butyl, etc, which herbicide comprises the components in parts by weight: 0.1-1 part of active ingredient(s), 70-80 parts of humic acid and 20-30 parts of silicon abundance ring, wherein the active ingredient(s) is/ are one or two in fluazifop-P-butyl, fluazifop-butyl and sethoxydim. The herbicide composition improves the weeding effect, and has beneficial effects for increasing the yield and the sugar content and accelerating the ripening of the sugarcane.
Description
Technical field
The invention belongs to agrochemical field, particularly relate to a kind of composition that comprises the weed killer herbicides such as humic acid and efficient fluazifop, concrete, relate to a kind of composition that comprises any one or two kinds in humic acid and efficient fluazifop or fluazifop or the sethoxydim.
Background technology
Sethoxydim belongs to the oximes weed killer herbicide, and being has a silk minute inhibitor, almost all grassy weeds is had high activity, to the invalid and safety of broad leaved weed.Be used for broad leaf crop (cotton, flax, rape, potato, soybean, sunflower and vegetables), use behind the bud, prevent and kill off annual gramineous weed.
Efficient fluazifop is mainly used in soybean, cotton, rape, the broad leaved plants such as peanut and wild cabbage.Prevent and kill off the annual and perennial grassy weeds such as barnyard grass, wild oat, green foxtail, Setaria glauca, eleusine indica, amur foxtail, moleplant seed, india lovegrass, bromegrass, Hordeum, Secale, millet genus, annual bluegrass, Bermuda grass, Paspalum distichum, false Chinese sorghum, reed, wild silkworm, cogongrass, quackgrass.
Efficient fluazifop absorbs rapidly by the blade face, and be hydrolyzed into fluazifop and by phloem and xylem transmission, be enriched in rhizome and the stolon of perennial weed, and annual and meristem perennial weed.Prevent and treat rape seed behind the seedling, sugar beet, fodder beet, potato, vegetables, cotton, soybean, the operatic circle, drupe, bush fruit, citrus fruit, pineapple, banana, strawberry, sunflower, alfalfa, the wild oat on ornamental plants and other broad leaf crop, wild cereal, annual and perennial weed.Control 2～3 leaf phase annual gramineous weeds, per hectare is with 500～750 milliliters of 15% fluazifop-p-butyls; 4～5 leaf phases of control, per hectare is with 750～1000 milliliters; 5～6 leaf phases of control, per hectare is with 1000～1200 milliliters.The little usefulness of weed size is hanged down dose, and leaf age is large uses high dose; In the good situation of moisture condition, with low dose, under drought condition, use high dose.Prevent and treat perennial grassy weed such as Bermuda grass, quackgrass, Paspalum distichum, false Chinese sorghum, reed per hectare with 2.0 liters.
Fluazifop is insoluble in water, is soluble in organic solvent, is cauline leaf inorganic agent behind a kind of seedling of high selectivity, and the lethality in having to life in 1 year and perennial grassy weed is to broad leaf crop safety, invalid to broadleaf weed.Weeds mainly absorb by cauline leaf receives conduction, and root also can Assimilation and conductivity.Poisoning symptom can occur in 48 hours after the general dispenser, then need 15 days but thoroughly kill weeds.Be applicable to the various crop such as soybean, cotton, beet, potato, sweet potato, peanut, pea, broad bean, Kidney bean, tobacco, flax, watermelon, reach rubber, fruit tree, plantation, forestry nursery, tending [after young plantation etc.Prevent and kill off life in 1 year and perennial grassy weed, such as non-irrigated barnyard grass, green foxtail, lady's-grass, eleusine indica, wild swallow grass, amur foxtail, bromegrass, arm shape grass, reed, Bermuda grass, Paspalum distichum etc.
Although these weed killer herbicides have good effect, and a lot of drawbacks are arranged when being applied to sugarcane field separately, herbicidal effect is not very desirable, and can not play other required effects.The present invention is directed to simultaneously lack effective weeding in the present sugarcane field and to sugarcane production-increasing, increase sugar and the situation of the herbicidal composition that accelerates the ripening, developed a kind of effective composition.
