Abstract
The invention discloses a herbicide composite for controlling cornfield weeds, in particular a herbicide for controlling cornfield poaceae weeds and broad-leaf weeds. The herbicide composite is a ternary herbicide mixture comprising the topramezone, the fluthiacet and the sodium methoxone as active components. The weight ratio of the topramezone to the fluthiacet to the sodium methoxone is (2-32):(0.5-8):(8-128). The compound herbicide can be prepared into water dispersible granules, wettable powder, suspending agents and dispersible oil suspending agents. The herbicide composite is used for controlling the cornfield weeds and has reasonable components; the control effect of the herbicide composite is superior to that of single component in application. The herbicide composite expands the weed control spectrum, reduces the control cost, relieves the generation of the weed resistance, has high safety on crops and meets the safety requirement on pesticide preparations.
Description
Technical field
The present invention relates to a kind of ternary herbicidal composition that contains benzene azoles humulone, fluthiacet and 2 first 4 chlorine sodium, can be used for the control of maize weeds in field.
Background technology
At present, China's corn field herbicide kind only has atrazine, first grass piperazine, alachlor, Acetochlor, isopropyl methoxalamine, propisochlor, thifensulfuronmethyl, nicosulfuron, trefanocide, 2,4-D etc. more than 10 plant, and wherein long residual effect weed killer herbicide atrazine consumption is excessive, exists huge hidden danger.China's corn field herbicide is badly in need of the short residual effect kind of development and cauline leaf inorganic agent, improve flexibility and the selectivity of cornfield weeding, suitably introducing on the basis of novel herbicide kind, exploitation is used for the weed killer herbicide mix preparation of corn field and improves operation technique emphatically, environmentally friendly herbicide synergist and safener that development and application adapts with it improve formulation of herbicide.
The English common name fluthiacet-methyl of fluthiacet, molecular formula C

2, chemical name [[the 2-chloro-4-fluoro-5-[(tetrahydrochysene-inferior pyridazine of 3-oxo-1H-3H-(1,3,4) thiadiazoles [3,4a]-1-yl) amino] phenyl] sulphur] methyl acetate.Use weed killer herbicide after the corn that system is developed by Japanese combinatorial chemistry company, Soybean Field seedling, be cauline leaf inorganic agent after tagging property seedling, the effect that can prevent and kill off the broad leaved weeds such as corn field piemarker, lamb's-quarters, smartweed can reach 90%, the preventive effect of the broad leaved weeds such as dayflower is only had 50%, grassy weed is not prevented and kill off effect.In 2～6 leaf phases of corn, 2～5 leaf phases of weeds use, and can effectively prevent and kill off weeds in field, and are all in 90% left and right, and good to crop safety to the preventive effects of various weeds, are more satisfactory mixture formulas.Japan's combinatorial chemistry is held fluthiacet patent EP 273417(1988); US 4906279(1990) out of date.With the kind of preventing and kill off broad leaved weed in weed killer herbicide, but that it prevents and kill off spectrum is narrow for present corn field, and only effective to broad leaved weed, use cost is high, limits its spread use.
The English common name topramezone of benzene azoles humulone, chemical name [3-(4,5-dihydro-3-isoxazolyl)-4-sulfonyloxy methyl-2-methylbenzene] 5-hydroxyl-1-methyl isophthalic acid H-pyrazoles-4-yl) ketone.After benzene azoles humulone belongs to the three ketones seedling, cauline leaf is processed weed killer herbicide, absorb by root and seedling, leaf, in plant Xiang Ding, be transmitted to meristematic tissue to base, suppress 4-HPPD, carotenoid, Chlorophyll biosynthesis are suppressed and function upsets, cause the susceptible weeds of germinateing to bleach symptom processing in 2-5 days, in 14 days, plant is dead.The anti-BAS670 011 of corn is based on weed killer herbicide target enzyme susceptibility lower, absorb, conduction slowly, metabolism is non-activity thing and tool selectivity rapidly.High activity, consumption are extremely low, use wide, flexible, broad weed-killing spectrum of optimum period after seedling, prevent and kill off annual warm season grassy weed and broad leaved weed.Be used for preventing and kill off the corn field annual weed, preventive effect is good, but exists independent use cost high, is unfavorable for large scale application.
2 first 4 chlorine sodium English name MCPA-Na, Chinese 2 first 4 chlorine sodium; 2-methyl-4-tomatotone, other title methoxone, virtue rice is large, Xing Fengbao, Nong Duosi, hundred is wealthy clean.As plant growth regulator, prevent the early stage fruit drops of fruit such as tomato on agricultural, and form the s.m.p fruit, promote crop precocious, accelerate rooting of cuttings.Also can make weed killer herbicide, after being used for seedling, cauline leaf is processed, easily more absorbed and conduction with leaf section, be used for granule cereal, paddy rice, corn, pea, lawn and noncrop area bud rear defence except multiple annual and perennial broadleaf weed, per hectare using dosage 0.28～2.25kg active ingredient.This product has special efficacy to broad-leaved and convexutricle sedge herb, also can prevent and kill off various dicotyledonous and some monocotyledon weed, but invalid to barnyard grass.
In actual use, fluthiacet is better to the effect of the broad leaved weeds such as the piemarker of corn field, lamb's-quarters, smartweed, but not satisfactory to part broad leaved weed preventive effect, and invalid to grassy weed; Benzene azoles humulone has preventive effect preferably as a kind of sulfonylurea corn field herbicide to part broad leaved weed, grassy weed, but invalid to the part broad leaved weed, and 2 first 4 chlorine sodium have special efficacy to broad-leaved and convexutricle sedge herb, but weeds are increasing to its resistance.Therefore, fluthiacet, benzene azoles humulone and 2 first 4 chlorine sodium are carried out rational mixture, to having remarkable synergy, corn field grass family and broad leaved weed are prevented and kill off in expansion control of weeds spectrum, a dispenser, reduce spraying times, reduce the effect of cost accounting.
Summary of the invention
The object of the present invention is to provide a kind of component reasonable, herbicidal spectrum is wide, and preventive effect is good, and drug cost is low, the herbicidal composition that contains benzene azoles humulone, fluthiacet and 2 first 4 chlorine sodium that is difficult for developing immunity to drugs.
Another object of the present invention is to provide above-mentioned composition to be used for preventing and kill off the purposes of grassy weed and broad leaved weed between corn field.
In order to overcome the defective of existing unitary agent, technical scheme of the present invention is to solve like this:
