Description

Containing Stam F-34, the herbicide composition for paddy fields of different grass pine

(1) technical field

The present invention relates to herbicide field, particularly to a kind of containing Stam F-34, different grass pine herbicide composition for paddy fields.

(2) background technology

Stam F-34, Acetochlor, pretilachlor, butachlor are all amide-type height selective herbicides, and except for the difference that Stam F-34 belongs to Contact killing type herbicide, and Acetochlor, pretilachlor, butachlor belong to inner-adsorption conduction-type herbicide.Stam F-34 is mainly used in rice seedling bed or straight Broadcast field, be to prevent and kill off the specific drug of barnyard grass it can also be used to prevent and kill off other multiple grass family and broadleaf weeds, as Monochoria vaginalis, Chinese celery, Lady's-grass, green bristlegrass etc.；Stam F-34 is transporting hardly in plant, simply works in medicament contact site, its mechanism of action It is many, not only breaks up the photosynthesis of plant, but also suppress respiration and phosphorylation, RNA and egg White matter synthesis etc., so that the physiological function of sensitive plant is affected, it is the most dried-up to accelerate dehydration, blade, finally dead.By In paddy rice body, be hydrolyzed enzyme in Stam F-34 and resolve into rapidly innocuous substance, paddy rice to the degradation capability of Stam F-34 than barnyard grass big 20 times, So to rice safety.

Acetochlor is mainly absorbed by the hypocotyl of monocotyledonous plumule or dicotyledon, absorbs backward uploading Lead, by hindering protein to synthesize and Cell growth inhibition, make the growth of weeds young shoot, young root stop, so dead；Grass family is miscellaneous The energy force rate broad leaved weed that grass absorbs Acetochlor is strong, so the effect preventing and kill off grassy weed is better than broad leaved weed.Acetochlor exists About 45 days lasting period in soil, mainly by microbial degradation, the mobility in soil is little, is primarily retained in 0 ~ 3 li In rice soil layer.Butachlor is mainly absorbed by the young shoot of weeds, then conducts complete stool and works, and all can make with seedling stage before bud With.After plant absorption butachlor, suppress in vivo and destroy protease, affecting the formation of protein, suppression weeds young shoot and children Root normal growth is grown, so that weeds are dead；Using on the soil that clay loam and the content of organic matter are higher, medicament can be native Earth colloid absorbing, is difficult to be leached, and the special efficacy phase was up to 1 ~ 2 month.Pretilachlor is that weed seed absorbs medicament in germination process, Root absorption is poor, can only make soil treatment before bud.Paddy rice germination period is the most sensitive to pretilachlor, for ensureing the peace of medication in early days Entirely, pretilachlor is commonly incorporated into safener and is used together.Butachlor is mainly absorbed by the young shoot of weeds, then conducts complete stool and acts as With, all can use with seedling stage before bud.After plant absorption butachlor, suppress in vivo and destroy protease, affecting the shape of protein Becoming, suppression weeds young shoot and young root normal growth are grown, so that weeds are dead；At the soil that clay loam and the content of organic matter are higher Using on earth, medicament can be absorbed by soil colloid, is difficult to be leached, and the special efficacy phase was up to 1 ~ 2 month.

Different grass pine is selective systemic herbicide, is absorbed by the root of plant, young shoot, and upwards transporting, through xylem Diffuse to leaf portion, the chlorophyll of suppression sensitive plant and the synthesis of carrotene.Form white seedling, dead in a short time.Lasting period Long, sustainable more than 6 months of different grass pine biologically active in soil, can be under RD, after selectively arranging, stubble is made Thing, it is to avoid poisoning.

(3) summary of the invention

The present invention is in order to make up the deficiencies in the prior art, it is provided that a kind of prevention effect is good, to rice safety containing Stam F-34, The herbicide composition for paddy fields of different grass pine.

The present invention is achieved through the following technical solutions:

A kind of containing Stam F-34, different grass pine herbicide composition for paddy fields, with Stam F-34 and different grass pine basic material, its It is characterised by: in basic material, add at least one in Acetochlor, pretilachlor or butachlor, and 2,4-D butyl ester, 2,4- At least one in the different monooctyl ester of D or MCPA,MCP,methoxone, is prepared under the cooperation of auxiliary agent or filler, wherein, and the weight of each raw material Score ratio be in Stam F-34 5 ~ 35%, different grass pine 2 ~ 20%, Acetochlor, pretilachlor or butachlor at least one 5 ~ 35%, 2,4-D Butyl ester, 2, in the different monooctyl ester of 4-D or MCPA,MCP,methoxone at least one 0.5 ~ 10%, remaining is auxiliary agent or filler.

The present invention adds at least one in Acetochlor, pretilachlor or butachlor, and 2 in Stam F-34 and different grass pine, 4-D butyl ester, 2, at least one in the different monooctyl ester of 4-D or MCPA,MCP,methoxone, to rice safety, the above the average age for marriage barnyard grass of antagonism, long awns barnyard grass, rice Barnyard grass and broad-leaved malignant weed have a good activity of weeding, and meanwhile, above-mentioned composition also allows the characteristic of increasing production of rice.

2,4-D butyl esters, 2, the different monooctyl ester of 4-D, MCPA,MCP,methoxone are phenoxy carboxylic acid hormone-type selective herbicides, have stronger Uptake and translocation, broad weed-killing spectrum herbicidal effect is good, lower-price characteristic.

The mechanism of action of the various compositions of the present composition is different, is mutually improved, under resistance weed between them Fall, the herbicidal effect of composition is apparently higher than each combination herbicidal effect time alone, and herbicidal spectrum is wider.

The more excellent scheme of the present invention is:

Described basic material is also added with at least one in bensulfuron-methyl, pyrazosulfuron or azimsulfuron, wherein This composition accounts for the 0 ~ 5% of total raw material weight.

Bensulfuron-methyl, pyrazosulfuron, azimsulfuron belong to sulfonylurea herbicide, and activity is high, and consumption is few；In belonging to again Inhale translocated herbicide.Medicament spreads rapidly in water, transfers to other position, hinder and prop up after weeds root and blade absorb Chain amino acid biosynthesis.Susceptible weeds GF is obstructed, tender tissue turns to be yellow too early, suppresses leaf portion, root growth.Can have Effect prevents and treats rice field life in 1 year and perennial broadleaf weed and nutgrass flatsedge, can be absorbed by weeds root, leaf and pass to other positions.To paddy rice Safety, using method is flexible.

Described herbicidal composition is that missible oil, wettable powder, suspending agent, pulvis, granula, dry suspending agent or oil suspend Agent.

The yield one improving paddy rice realizes by regulating each component ratio and pipe fitting amounts of components, concrete real Execute in scheme, be that the amount of 4-D butyl ester increases rice yield by regulation 2.

The auxiliary agent of the present invention or filler are the surface reactive materials such as emulsifying agent, dispersant, wetting agent, to increase composition Stability, wetability and permeability.

The present invention can be used by commonsense method, as poured into a mould, spray, spray or dusting.

The present invention is mutually combined by several conventional chemical herbicides, the prevention effect that can reach weeds and to paddy rice Safety, solves the different grass pine key to paddy rice albefaction, and different grass pine can be made to bring up in rice terrace effective ingredient consumption 50g/ mu so that it is recommend three times of consumption and paddy rice not albefaction.
