Abstract
The invention belongs to the field of pesticide, in particular to special herbicide for corns. In the herbicide, effective active ingredients of flumetsulam and halosulfuron-methyl are mutually mixed and prepared, the contradiction cannot be caused, the herbicide controlling spectrum is wide, most annual and perennial weeds can be prevented and killed, the weeds growing out of the ground can be effectively killed, the weeds which do not grow out of the ground can also be controlled, and the weeding effect is improved. The effective ingredients in the herbicide are matched in a certain range, a good synergistic effect is realized in a certain range, the prevention effect is higher than that of the single dosage, the drug property maintenance time is long, the herbicide is safe to the corn in the current period and the corn in the next period, herbicide safety agents of furilazole are used, and the safety of corn crops can be ensured.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of corn herbicides special.
Background technology
Flumetsulam belongs to triazolopyrimidine sulfonamides, and sterling is canescence, tasteless solid; 251～253 ℃ of fusing points; Density 1.77 (21 ℃); Vapour pressure is 1.6 * 10-10Pa (25 ℃).Distribution coefficient LogP=-0.68; In water, solvability is 49mg/l (pH2.5).Flumetsulam is the inhibitor of a kind of typical acetolactate synthestase (ALS).Due to its serious inhibitory action, be that in plant corpus, branched-chain amino acid--leucine, valine and isoleucine biosynthesis stop, protein biosynthesis block, growth retardation, finally dead.Flumetsulam is a kind of broad spectrum weeding agent, can prevent and kill off most of annual and perennial broadleaf weeds, children grassy weed in age is also had to inhibitory action, as piemarker, lamb's-quarters, chickweed, tattooing flower are harvested, clearvers, Mandala, Amaranthus retroflexus, pineapple weed, corn radish isoreactivity be excellent, the multiple cruciferous weeds such as knotweed, summer cypress, black nightshade, white dead nettle, Veronica, flowerofanhour root or herb, Siberian cocklebur and elegance and talent dish, penny cress are had to significant preventive effect, green foxtail, Chufa are also had to good activity.
Halosulfuronmethyl is the same with other sulfonylurea herbicide is the inhibitor of acetolactate synthestase (ALS).By weeds root and leaf, absorb, in plant body, conduct, weeds stop growing, then withered.Halosulfuronmethyl be mainly used in preventing and kill off broad leaved weed and sedge weed as piemarker, storehouse ear, Datura, artemisiifolia, Amaranthus retroflexus, flowerofanhour root or herb, knotweed, kitchen garden, black nightshade, Cassia tora, lead a cow, the rhizome of nutgrass flatsedge etc.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of corn herbicides special.In weed killer herbicide of the present invention, effective active composition Flumetsulam, halosulfuronmethyl are mutually mixed and can produce conflict; Broad weed-killing spectrum, can prevent and kill off most of annual and perennial weeds, not only effectively kills the weeds after being unearthed, and also can control the weeds of not being unearthed, and improves herbicidal effect; Active ingredient in weed killer herbicide of the present invention coordinates good synergistic effect within the specific limits, and preventive effect is higher than single dose, the property of medicine length of holding time; To when stubble corn and succession crop safety, used herbicide-safener furilazole, can guarantee the safety of corn crop.
A kind of corn herbicides special of the present invention is to realize by following technical scheme: the active ingredient of described weed killer herbicide comprises: Flumetsulam, halosulfuronmethyl.
Described Flumetsulam, the part by weight of halosulfuronmethyl are 1-10:1-10.
The part by weight of Flumetsulam, halosulfuronmethyl is 4:1.
In this weed killer herbicide, also contain furilazole.
Weed killer herbicide is water dispersible granules.
In weed killer herbicide, Flumetsulam, halosulfuronmethyl account for 50-80 part of weed killer herbicide gross mass, also comprise furilazole 5-15 part, dispersant 3-20 part, wetting agent 3-10 part, disintegrant 3-6 part, filler 1-70 part.
Flumetsulam, halosulfuronmethyl, furilazole and dispersant, wetting agent, disintegrant and filler are mixed, with micro jet, pulverize, through mediating, then add in fluidized bed prilling dryer and carry out granulation, dry, screening, make the water dispersible granules of bactericidal composition.
Described dispersant is at least one in polycarboxylate, lignosulfonates, aliphatic amine polyoxyethylene ether, polyoxyethylene carboxylate;
Described wetting agent is at least one in lauryl sodium sulfate, calcium dodecyl benzene sulfonate, alkylnaphthalene sulfonate, spaonin powder, silkworm excrement, soapberry powder;
Described disintegrant is at least one in urea, ammonium sulfate, aluminium chloride, citric acid, succinic acid, sodium bicarbonate;
Described filler is at least one in kaolin, diatomite, bentonite, white carbon, starch, precipitated calcium carbonate.
In weed killer herbicide, contain 4 parts, 6 parts of 10 parts of 8 parts of 15 parts of 60 parts of Flumetsulams, halosulfuronmethyls, furilazoles, lignosulfonates, calcium dodecyl benzene sulfonates, ammonium sulfate, 30 parts, diatomite by weight.
Beneficial effect of the present invention: in weed killer herbicide of the present invention, effective active composition Flumetsulam, halosulfuronmethyl are mutually mixed and can produce conflict; Broad weed-killing spectrum, can prevent and kill off most of annual and perennial weeds, not only effectively kills the weeds after being unearthed, and also can control the weeds of not being unearthed, and improves herbicidal effect; Active ingredient in weed killer herbicide of the present invention coordinates good synergistic effect within the specific limits, and preventive effect is higher than single dose, the property of medicine length of holding time; To when stubble corn and succession crop safety, used herbicide-safener furilazole, can guarantee the safety of corn crop.
