Abstract
A compounded preparation for preventing and killing weed of rice field is made up by using (wt%) 2%-10% of s-metalochlor, 0.2%-5% of bensulfuron-methyl as effective components, 0.5%-1% of stabilizing agent sulfate and phosphate, 5%-15% of adjuvant sodium lignosulfonate and carrier kaoling, clay and pottery clay, etc. which are added to 100%. Said invention is a wettable powder, and can effectively prevent and kill various weeds of rice field.
Description
The present invention relates to a kind of composition pesticide, relate in particular to a kind of smart isopropyl methoxalamine of killing weeds in rice field and complex preparation of bensulfuron-methyl of being used for.
Smart isopropyl methoxalamine (s-metalochlor) is that Switzerland Novartis Co.,Ltd (NOVARTIS) Application Optics disassemble technique carries out optical resolution to isopropyl methoxalamine, removed the non-active portion R isomer (R body) in the isopropyl methoxalamine (metalochlor), and obtain highly finished product S isomer (S body).
The chemical structural formula of smart isopropyl methoxalamine is:
Smart isopropyl methoxalamine is the bud scale by monocotyledon weed mainly, or the young shoot of broadleaf weed and young root absorb.Upwards conduction suppresses the growth of the root of young shoot.Disturb weeds body internal protein synthetic, and lecithin is formed with remote-effects, cause weeds death.Smart isopropyl methoxalamine can effectively be prevented and kill off the annual gramineae grass and the part nutgrass flatsedge in rice field, as barnyard grass grass, difformed galingale herb, fescue etc.
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 Duck tongue grass, 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 structural formula of bensulfuron-methyl is:
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 present invention is achieved in that the complex preparation of a kind of smart isopropyl methoxalamine and bensulfuron-methyl, be characterized in that effective ingredient is smart isopropyl methoxalamine (s-metalochlor) and bensulfuron-methyl (bensulfuron-methyl) in the complex preparation, smart isopropyl methoxalamine content is 2%～10% (weight) in the preparation, bensulfuron-methyl content is 0.2%～5% (weight), all the other are that adhesive, stabilizing agent, auxiliary agent and carrier add to 100% (weight) and make wetting powder, and effective component content is 2.2%～15% (weight) in the wetting powder.
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 smart isopropyl methoxalamine of the present invention and bensulfuron-methyl is granule or wetting powder, is used for preventing and kill off grass family, broad-leaved section and the sedge weed of transplanting rice field.
The pulvis carrier of wetting powder is kaolin, diatomite, clay, potter's clay, bentonite etc.Auxiliary agent is sodium lignin sulfonate or calcium, draw back powder, dodecyl sodium sulfonate calcium etc.
Smart isopropyl methoxalamine 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 smart isopropyl methoxalamine and bensulfuron-methyl, and smart isopropyl methoxalamine is the selectivity preemergence herbicide, mainly absorbs by weeds coleoptile and young 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.
