Abstract
The invented compounded preparation for eliminating weeds in rice field is composed of effective compoent (wt.%): pretilachlor 10-50 and bensulfuron-methyl 0.2-5, and binder polyvinyl alcohol 1.0-2.0, stabilizer sulfate and phosphate 0.5-1, adjuvant sodium lignosulfonate 5-15 and carrier kaolin, clay, pottery clay addition to 100 wt.%. The invented agent is in the form of pellet or wettable powder.
Description
The present invention relates to a kind of composition pesticide, relate in particular to a kind of third careless amine of killing weeds in rice field and complex preparation of bensulfuron-methyl of being used for.
Bensulfuron-methyl (bensulfuron-methyl) is to inhale the conduction weed killer herbicide in the selectivity, effective ingredient can spread rapidly in water, for weeds root and blade absorb each one of weeds that transfers to, by suppressing the activity of acetolactate synthestase, make the branched-chain amino acid biosynthesis block, the biosynthesis of hindered aminoacid, lysine, isoleucine stops the division and the growth of cell, cause the weed growth function to be obstructed, make the weeds necrosis.It kills the grass spectrum and is applicable to the broad leaved weed of preventing and kill off the rice field, as Monochoria vaginalis, pondweed, mexicana, Procumbent Falsepimpernel etc., reaches sedge weed such as fescue, difformed galingale herb, Herba Cyperi Glomerati, cyperus iria etc.But to preventing and kill off the active low of barnyard grass grass, application can not be prevented and kill off grass family in the rice field, broad-leaved section and sedge weed fully separately.
The purpose of this invention is to provide a kind of grass spectrum of killing and have complementary advantages, can prevent and kill off the third careless amine of grass family in the rice field, broad-leaved section and sedge weed and the complex preparation of bensulfuron-methyl fully.
The third careless amine (pretilachlor) is the selectivity preemergence herbicide that Switzerland Novartis Co.,Ltd (NOVARTIS) develops.
The chemical structural formula of the third careless amine is:
The third careless amine mainly absorbs by plant hypocotyl, mesocotyl and coleoptile, directly disturbs weeds body internal protein synthetic, and photosynthetic and respiration are had remote-effects, causes weeds death.And paddy rice has stronger capacity of decomposition to the third careless amine, thereby has certain selectivity.The third careless amine can effectively be prevented and kill off the annual gramineae grass and the part broad leaved weed in rice field, as barnyard grass grass, Monochoria vaginalis, Herba Ammanniae Bacciferae etc., but to the sedge weed weak effect.
The structural formula of bensulfuron-methyl is:
The present invention is achieved in that the complex preparation of a kind of third careless amine and bensulfuron-methyl, be characterized in that effective ingredient is the third careless amine (pretilachlor) and bensulfuron-methyl (bensulfuron-methyl) in the complex preparation, the third careless amine content is 10%～50% (weight) in the preparation, bensulfuron-methyl content is 0.2%～5% (weight), all the other are adhesive, stabilizing agent, auxiliary agent and carrier add to 100% (weight) and make granule or wetting powder, effective component content is 10.2%～52% (weight) in the granule, and effective component content is 10.2%～55% (weight) in the wetting powder.
Adhesive described in the present invention is polyvinyl alcohol, polyvinyl acetate, starch and gum Arabic, accounts for 1.0%～2.0% (weight) of preparation.
Stabilizing agent described in the present invention is sulphate and phosphate, the sulphate stabilizing agent is barium sulfate, calcium sulphate, phosphate stabilizer is dipotassium hydrogen phosphate, sodium, ammonium salt, the potassium or the sodium salt of potassium dihydrogen phosphate, sodium, ammonium salt, pyrophosphoric acid, tripolyphosphate, four polyphosphoric acids, metaphosphoric acid, single using or the mixing application accounts for 0.5%～1% (weight) of preparation.
Auxiliary agent described in the present invention is sodium lignin sulfonate or sulfoacid calcium, draws back powder, dodecyl sodium sulfonate calcium, accounts for 5%～15% (weight) of preparation.
Carrier described in the present invention is kaolin, diatomite, sand, clay, potter's clay, bentonite, adds to 100% (weight).
The complex preparation of the present invention's third careless amine and bensulfuron-methyl is granule or wetting powder, is used to prevent and kill off transplanting rice field, or seedlings rice seedling Tanaka's grass family, broad-leaved section and sedge weed.
Granule can be used coating method, mediate manufactured, and carrier is kaolin, diatomite, sand, clay, potter's clay, bentonite etc., and adhesive is polyvinyl alcohol, polyvinyl acetate, starch, gum Arabic etc.
The pulvis carrier diatomite of wetting powder, clay, potter's clay, bentonite etc.Auxiliary agent is sodium lignin sulfonate or calcium, draw back powder, dodecyl sodium sulfate etc.
The third careless amine and bensulfuron-methyl mix and can cause that bensulfuron-methyl slowly decomposes, and add barium sulfate or calcium sulphate and phosphatic mixture in the preparation as stabilizing agent, and effect is fine.
The present invention is with the complex preparation of making of the third careless amine and bensulfuron-methyl, and the third careless amine is the selectivity preemergence herbicide, mainly absorbs by weeds young shoot coleoptile and immature secondary root, disturbs weeds body internal protein to synthesize and causes weeds death; Bensulfuron-methyl is to inhale the conduction weed killer herbicide in the selectivity, by suppressing the activity of acetolactate synthestase, makes the branched-chain amino acid biosynthesis block, and the division of cell and growth are destroyed.Because therefore the site of action difference of two kinds of weed killer herbicides in the weeds body improved and killed careless effect.It is with strong complementarity to kill the grass spectrum, and the spectrum of grass extremely of broad is arranged, and can effectively prevent and kill off all weeds in the rice field, comprises grass family, broad-leaved section and sedge weed, has remedied bensulfuron-methyl and has killed the shortcoming that grass is composed, and has solved most of weeds problem in rice field.
Be embodiments of the invention below; Each component ratio (weight %) among the present invention
The listed prescription of above-mentioned embodiment 1-10 is not the restriction to aforementioned each component proportioning of the present invention, but content of the present invention is described further.
The effective ingredient of the complex preparation among the above-mentioned embodiment 1-10 is third careless amine and the bensulfuron-methyl.Stabilizing agent is barium sulfate or calcium sulphate and phosphatic mixture.Auxiliary agent is sodium lignin sulfonate, calcium lignosulfonate, draw back powder, dodecyl sodium sulfonate calcium.Carrier is kaolin, diatomite, sand, clay, potter's clay, bentonite.Adhesive is polyvinyl alcohol, polyvinyl acetate, starch, gum Arabic.
