Description

A kind of Herbicidal combinations of the secondary monooctyl ester containing fluroxypramide
Technical field
The present invention relates to a kind of weeding class composition pesticides, especially for being suitable for wheat, barley, corn, grape, fruit Prevent and kill off broadleaf weeds in the ground such as garden, pasture, forest land, lawn.
Background technique
Fluroxypramide (also known as are as follows: fluroxypramide acid) is a kind of inner sucting conduction type postemergence weed control of Dow Chemical Company exploitation Agent has good prevent and kill off to a variety of annual or perennial broadleaf weed in wheat, barley, wheat, corn field and orchard etc. Effect.Fluroxypramide molecular formula C7H5Cl2FN2O3, molecular weight 255.03, No. CAS: 69377-81-7, structural formula is as shown in Equation 1. Its Full Name in English 2- (4-amino-3,5-dichloro-6-fluoropyridin-2-yloxy) acetic acid, English letter Claim Fluroxypyr.Fluroxypramide Chinese chemical name is known as the fluoro- 2- pyridine fluoroacetic acid of the chloro- 6- of 4- amino -3,5- bis-, and Chinese is also known as Fluroxypyr.Sterling is white crystalline body, odorless, 232~233 DEG C of fusing point, vapour pressure 1.26 × 10-3Pa (25 DEG C), PKa value is 2.94.Its dissolubility are as follows: be soluble in acetone, chloroform, methylene chloride isopolarity solvent and medium polar solvent;Non- Solubility is lower in polar solvent (petroleum ether, n-hexane etc.);(91mg/L not soluble in water;25℃).It is more stable under room temperature, it can To stablize storage 2 years.Its fluroxypramide methyl ester derivation (the two fluoro- 2- pyridine fluoroacetic acid methyl esters of chloro- 6- of 4- amino -3,5-) is crystal (56~57 DEG C of fusing point), fluroxypramide ethyl ester derivative (the fluoro- 2- pyridine fluoroacetic acid ethyl ester of the chloro- 6- of 4- amino -3,5- bis-) be compared with For viscous liquid.Fluroxypramide belongs to pyridine fluoroacetic acid class herbicide, has uptake and translocation effect, belongs to typical hormone-type and remove Careless agent.It is used after seedling, the reaction of classical hormones class herbicide occurs in sensitive crop.It is wider using optimum period on cereal crop, It can be used for the ground such as wheat, barley, corn, grape and orchard, pasture, forest farm and prevent and kill off broadleaf weeds, such as clearvers, field bindweed, shepherd's purse The weeds such as dish, herba stellariae mediae, volume stem amaranth, purslane.
The secondary monooctyl ester molecular formula C of fluroxypramide15H21Cl2FN2O3, molecular weight 367.25, No. CAS: 81406-37-3, structural formula is such as Shown in formula 2.Its Full Name in English octan-2-yl 2- (4-amino-3,5-dichloro-6- fluoropyridin-2- Yloxy) acetate, English abbreviation Fluroxypyr 1-methylheptyl ester.The secondary monooctyl ester Chinese chemical name of fluroxypramide The referred to as fluoro- 2- pyridine fluoroacetic acid -1- methylheptyl ester of the chloro- 6- of 4- amino -3,5- bis-, Chinese are also known as fluroxypyr -1- Methylheptyl ester.Sterling is white crystalline body, odorless, 56~57 DEG C of fusing point.Pesticide original medicine content is generally 95-98%, has Soap scent.Acetone (62 g/L, 25 DEG C), methanol (250 g/L, 25 DEG C), methylene chloride (426 g/L, 25 DEG C) can be dissolved in Etc. various polarities organic solvent, (saturated concentration is about 0.9ppm in 25 DEG C of water) not soluble in water, octanol is with water partition coefficient 6140:1.Since strong acidity (pKa value 2.94) is presented in fluroxypramide, it is being easy to cause other to have with the mutual timing of other herbicides Imitate the decomposition of component, thus when being used as composition it is usually used be fluroxypramide acid Zhong Xin ester derivant it is (usually simple The referred to as secondary monooctyl ester of fluroxypramide.Although in fact, the secondary monooctyl ester of the fluroxypramide used on surface, the fluroxypramide substantially used, Because the secondary monooctyl ester of fluroxypramide be absorbed by plants it is internal, by metabolic degradation be fluroxypramide, to achieve the effect that weeding).Fluorine grass The secondary monooctyl ester of cigarette is inner sucting conduction type herbicide after seedling, is absorbed by plants quickly after medicine, so that sensitive plant classical hormones class is occurred and removes The reaction of careless agent, plant deformity, distortion.Temperature on the final effect of herbicide without influence, but influence its drug effect performance speed Generally when temperature is lower, drug effect performance is slower, stops growing after can making dunsiekte, but not dead immediately, and temperature is stood after increasing It is i.e. dead quickly.Broadleaf weeds, such as pig are prevented and kill off suitable for wheat, barley, corn, grape, orchard, pasture, forest land, lawn and other places Calamity, volume stem smartweed, purslane, black nightshade, herba stellariae mediae, field bindweed, knotweed, amaranth etc. are brought disaster to, it is invalid to gramineae weed.Fluroxypramide contains as one kind Efficient, less toxic, the low-residual herbicide of fluorine, are the developing ways of current new herbicides.Since it has in stubble and rear stubble Plant height safety;Working life is wide, and drug effect is fast, and dosage is low;Miscibilty is good, mixed with a variety of gramineous weed weedicides to increase Degrass spectrum and raising preventive effect.Resistance of rainwater washing against ability is strong, applies effect latter hour rainy the advantages that not influencing drug effect.Fluroxypramide Secondary monooctyl ester raw medicine toxicity is smaller, rat acute: LD50=2400mg/kg(rat oral), the acute LD of little white rabbit50>5000mg/kg (rabbit is percutaneous), rat suck LD50>296mg/m3(rat sucks 4 hours).Currently, the secondary monooctyl ester single dose of fluroxypramide is made with every liter Agent is sold containing the missible oil (trade name: keeping it grand) of 200 grams of secondary monooctyl esters of fluroxypramide (equivalent acid is 139 grams of fluroxypramide acid at equivalent), Fluroxypramide Zhong Xin ester content usually will not be too high in missible oil, this is because the limitation of its solubility.The secondary monooctyl ester of fluroxypramide also often with Other herbicides form mixture and use: can be mixed with the secondary monooctyl ester of fluroxypramide, Brominal, 2,4-D butyl ester, 2- first -4- chlorine etc..Corn Commeline communis, field bindweed, purslane, small japanese bearbind etc. are prevented and kill off in field, per acre with 20% fluroxypramide missible oil 70-100mL.Wheat paddock is used per acre 20% fluroxypramide missible oil 50-100mL.20% fluroxypramide missible oil 80-150mL is used in vineyard, orchard, pasture per acre.Insecticide spraying time: It is miscellaneous: the 2-4 leaf phase.It is spraying with liquid volume 15-30kg per acre.
The secondary monooctyl ester structural formula of fluroxypramide is relative complex, therefore its synthesis route is more, is mainly the following synthesis Technique.The first is alkylation process (bibliography: United States Patent (USP), patent name: Herbicidal use of Aminohalopyridyloxy acid and derivatives thereof, inventor Stanley D. Megregor Deng: US:4110104,1978-08-29): this method is by the chloro- 6- fluorine pyridine -2- phenol potassium of 4- amino -3,5- bis- and monoxone Zhong Xin Ester is directly etherified and obtains product.Pyridine obtains penta chloropyridine through superchlorination for starting material, by fluorination, ammonification, three steps of hydrolysis Reaction obtains the chloro- 6- fluorine pyridine -2- phenol potassium of important intermediate 4- amino -3,5- two.Meanwhile monoxone and sec-octyl alcohol are urged in sulfuric acid Change lower esterification and obtains another secondary monooctyl ester of intermediate monoxone.Then the chloro- 6- fluorine pyrrole of intermediate 4- amino -3,5- two Pyridine -2- phenol potassium and the secondary monooctyl ester of intermediate monoxone, which are directly etherified, obtains the secondary monooctyl ester of product fluroxypramide.The advantages of this route is route Simply.This synthesis technology committed step etherification procedure, yield is not high, and purity is lower, purifies relative difficulty;Second is transesterification Method (bibliography: United States Patent (USP), patent name: Preparation of higher alkylesters of Carboxylicacids, inventor Lan R. Kings etc.: US:5214150,1993-05-25): this method is fluroxypramide methyl esters Ester exchange reaction, which is carried out, with sec-octyl alcohol obtains product.Pyridine obtains penta chloropyridine through superchlorination for starting material, by fluorination, ammonia Change, hydrolysis three-step reaction obtains the chloro- 6- fluorine pyridine -2- phenol potassium of important intermediate 4- amino -3,5- two.Intermediate 4- amino- The chloro- 6- fluorine pyridine -2- phenol potassium of 3,5- bis- and methyl chloroacetate carry out condensation reaction and obtain intermediate fluroxypramide methyl esters.Intermediate fluorine Careless cigarette methyl esters and sec-octyl alcohol carry out ester exchange reaction and obtain the secondary monooctyl ester of product fluroxypramide.The advantages of this route be product purity compared with It is good, it purifies relatively easy.The disadvantage is that temperature reaches 160 DEG C in ester exchange reaction, and system needs to depressurize, to equipment requirement Higher, overall operation is also more complicated than alkylation process.The third is alcoholic extract hydroxyl group carboxylic acid ester process (bibliography: United States Patent (USP), proprietary term Claim: Aminohalopyridyloxy acid and derivativesthereof, inventor Stanley D. Megregor Deng: US:3761486,1973-9-25): this method is 4- amino -3,5- bis- chloro- 2, and 6- difluoro pyridine and the secondary monooctyl ester of hydroxyacetic acid are straight It taps into row reaction and obtains product.Pyridine obtains penta chloropyridine through superchlorination for starting material, obtains by fluorination, ammonification two-step reaction To the chloro- 2,6- difluoro pyridine of intermediate 4- amino -3,5- two.The chloro- 2,6- difluoro pyridine of intermediate 4- amino -3,5- two and hydroxyl The secondary monooctyl ester of guanidine-acetic acid carries out condensation reaction and obtains the secondary monooctyl ester of fluroxypramide.The advantages of this route is that synthesis step is short, easy to operate.It lacks Point is that condensation reaction yield is not high, and product purity is lower, it is most important that raw material hydroxyl sec-octyl acetate is expensive (than current The secondary monooctyl ester price of fluroxypramide is higher by by about one time on the market), there is presently no industrial values.4th kind is methyl sulfone intermediate method (bibliography: United States Patent (USP), patent name: Optically active phenoxypropionic acid Derivatives, inventor Koichi. Moriya etc.: US:4596599,1986-6-24): this method is 4- amino -3,5- bis- Chloro- 6- fluorine pyridine -2- methyl sulfone is directly reacted to obtain product with the secondary monooctyl ester of hydroxyacetic acid.Pyridine is starting material through superchlorination Penta chloropyridine is obtained, obtains chloro- 2, the 6- difluoro pyridine of intermediate 4- amino -3,5- bis- by fluorination, ammonification two-step reaction.In this The chloro- 2,6- difluoro pyridine of mesosome 4- amino -3,5- two and chloro ethyl mercaptan are condensed to yield 4- amino -3,5- under sodium methoxide catalyzed The two chloro- fluoro- 2- methylsulfanyl pyridine intermediates of 6-, the bis- fluoro- 2- methylsulfanyl pyridine of chloro- 6- of intermediate 4- amino -3,5- use dioxygen Water, which further aoxidizes, obtains the chloro- 6- fluorine pyridine -2- methyl sulfone of intermediate 4- amino -3,5- two.Intermediate 4- amino -3,5- two is chloro- 6- fluorine pyridine -2- methyl sulfone and the secondary monooctyl ester of hydroxyacetic acid carry out condensation reaction and obtain the secondary monooctyl ester of fluroxypramide.The advantages of this route is tool There is stronger originality, the original synthetic route of patent can be evaded.The disadvantage is that reaction step is tediously long, condensation reaction yield is not high, produces Product purity is lower, most important defect be also will use expensive raw material hydroxyl sec-octyl acetate (the secondary monooctyl ester of hydroxyacetic acid, Than the secondary monooctyl ester price of fluroxypramide is higher by by about one time on the market at present), while the sodium methoxide, highly concentrated that also use price relatively high Hydrogen peroxide is spent, therefore the route only only has research significance at present, there are no industrial values.5th kind is sodium methoxide method (ginseng Examine document: the synthetic method of Cheng Xia, New Herbicides fluroxypramide summarize [J], Xi'an Petroleum University's journal (natural science edition), 1990,21 (3): 27-29): this method be the two fluoro- 2- methoxypyridine of chloro- 6- of 4- amino -3,5- and the secondary monooctyl ester of monoxone directly into Row condensation reaction obtains product.Pyridine obtains penta chloropyridine through superchlorination for starting material, obtains by fluorination, ammonification two-step reaction To the chloro- 2,6- difluoro pyridine of intermediate 4- amino 3,5- bis-.The chloro- 2,6- difluoro pyridine of intermediate 4- amino 3,5- bis- and methanol Sodium reacts to obtain the fluoro- 2- methoxypyridine intermediate of the chloro- 6- of 4- amino -3,5- bis-, and the chloro- 6- of intermediate 4- amino -3,5- bis- is fluoro- 2- methoxypyridine and the secondary monooctyl ester of monoxone carry out condensation reaction and obtain the secondary monooctyl ester of fluroxypramide.The advantages of this route is synthesis step It is short.The disadvantage is that condensation reaction yield is very low, product purity is not also high, therefore the route synthesis cost is higher.
Wheat cultivated area over the years in China's is the 22% ~ 30% of the whole nation cultivation ground gross area, cultivated area be even more reach 4.2 ~ 5.5 hundred million mu.Weeds in wheat paddock are divided into broadleaf weed and monocotyledon weed.Broadleaf weed is called broadleaf weeds.Soybean, Peanut belongs to dicotyledon, and broadleaf weed is similar to soybean, peanut, and also there are two cotyledons when emergence.It is single as corn Only one cotyledon of cotyledon weeds.Both types weeds are widely different to the sensitivity of herbicide.It turns green to jointing, wheat The common broadleaf weed of Tanaka has Descurainia sophia, Herba Galii Teneri, herba stellariae mediae, shepherd's purse, conical silene herb, corn gromwell, sandwort, wartwort etc..It broadcasts Ma wormwood artemisia also known as wheat wormwood artemisia, Descurainia sophia germination and emergence before the winter belong to winter annual weeds.This is the Descurainia sophia of strain.Descurainia sophia is in wheat harvest Preceding seed is mature.Shepherd's purse is also winter annual weeds.It emerges after wheat cultivation.Continued growth after wheat is turned green, and bolting is bloomed, and is arrived Seed is mature before wheat harvest.Herba Galii Teneri is called drawing and draws rattan, glues stickweed, and snake shell grass belongs to winter annual weeds.Conical silene herb is called rice watt Tank, this is the conical silene herb of period of seedling establishment, arrives wheat booting period, and conical silene herb starts to bloom.Wheat weeds when wheat is turned green be goose not Food.The corn gromwell grown in wheatland, belongs to Boraginaceae.It also blooms in wheat booting period.Wheat is turned green the list common to jointing Cotyledon weeds have: amur foxtail, wild avena sativa etc..Common cornfield gramineae weed has wild avena sativa, amur foxtail, barnyard grass, herba setariae viridis, hard Grass, herba digitariae, herba eleusines indicae etc..The herbicide that common wheatland prevents and kill off gramineae weed has galloping horse, diclofop-methyl, suffer, oat fear, kills Careless pellet, molinate, Avadex, blueness Yan Ling, difenzoquat etc..Common wheatland broadleaf weeds has purslane, clearvers, field thistle (thorn Youngster's dish), it is shepherd's purse, rice crock, sowthistle, humulus grass (drawing is uprooted plants after their edible portions have been harvested), Siberian cocklebur, Descurainia sophia, garden sorrel, leaf knotweed, field bindweed, Amaranthus retroflexus, recessed Head amaranth, ivy glorybind, sonchus oleraceus etc..The herbicide for preventing and kill off broadleaf weeds for wheatland has 2,4- d butyl ester, dimethyl tetrachloride, benzene to reach Pine, tribenuron-methyl, dicamba, metsulfuron-methyl, green sulphur is grand, fluroxypyr, symetryne, Brominal, ioxynil etc..National wheat paddock Cultivated area is big, weeds huge number, and same kind is used for a long time or same veriety is all easy to produce resistance, it is therefore desirable to Herbicide kind does not stop to weed out the old and bring forth the new.
China is one of Chan Mian big country, the world, wherein with provinces and regions such as Shandong, Ji, Henan, Soviet Union, Hubei Province, new, Anhui for main cotton growing area. Weed in cotton field mainly has 24 sections about more than 60, wherein with the herba digitariae in gramineae weed, herba eleusines indicae, semen euphorbiae, non-irrigated barnyard grass, dog tail It is maximum that density occurs for grass, Paspalum distichum, Bermuda grass etc.;Broadleaf weeds is with Eclipta prostrata, Amaranthus retroflexus, argy wormwood, chenopodium glaucum linn, Acalypha-austratis-L, piemarker Based on fiber crops etc.;Sedge weed is based on the rhizome of nutgrass flatsedge.In Yellow River basin cotton region, with the rise of temperature, cotton field after sowing cotton seed A variety of weeds start rudiment successively, until mid or late May forms first emergence peak in field, at this time with herba setariae viridis, herba digitariae, drought Based on barnyard grass, Chenopodiaceae etc., with rainfall and pour water later it may also occur that primary small germination peak;To July, with the arrival in rainy season, The weeds such as the rhizome of nutgrass flatsedge are largely unearthed, and second germination peak is formed, and at the same time, the weeds that early period is unearthed enter growth most flower Phase, thus easily cotton is caused seriously to cause harm.China cotton field is widely distributed, and different cotton region weed communities and dominant population are not Together.Yangtze river basin cotton region has a moderate climate with heavy rainfall, is suitable for weed growth, and dominant weed is with herba digitariae, herba eleusines indicae and the rhizome of nutgrass flatsedge It is main.To like to form various weed communities based on cool resistance to early weeds, common weed mainly has herba digitariae, Bermuda grass, dish etc. for North china It is a variety of.Since the herbicide kind of single type is used for a long time, the variation of farmland weed population and the succession of community accelerate, certain secondary Weeds are increasingly becoming main weeds, and intractable weed harm is got worse, and increase chemical weed control difficulty.The chemical weed control of China cotton field There are the problem of be that method of administration is improper first.The distribution of China cotton field is wide, after the generation of planted in different ecological areas weeds and spraying herbicide Primary and secondary wants the succession of herbaceous of weeds still to lack further investigation, not formed targetedly to prevent and kill off the section's general education being formulated to numerous cotton growers Educate deficiency, the not perfectly flat weighing apparatus of various regions application technology level, because selecting medicament and administration time, dosage method etc. no in practice When often resulting in phytotoxicity.The chemical weed control of China cotton field starting late, fundamental research is weaker, cotton field chemical weed control kind compared with It is few, it carries out in a deep going way and more effectively applies there is an urgent need to research.These factors all make cotton field herbicide need constantly to release Effect is more preferable, the wider array of new varieties of degrass spectrum.
In addition, the farmlands such as Soybean Field, sugarcane field, corn field, Rapeseed Field, tea place and bare place weeding equally have it is numerous miscellaneous Grass.By taking common soybean weeds as an example, soybean weeds can be divided into three categories in the sense that preventing and kill off, i.e. annual gramineae Weeds, annual broadleaf weed and perennial weeds.Soybean Field annual gramineous weed mainly has barnyard grass, herba setariae viridis, golden dog Tail grass, wild broomcorn millet, herba digitariae, wild avena sativa etc..Soybean Field annual broadleaf weed mainly has Amaranthus retroflexus, Siberian cocklebur, black nightshade (black star), iron Three-coloured amaranth, Chenopodiaceae (Chenopodium album), bog marshcress herb, piemarker, water spine pin, willow leaf thorn smartweed, herba stellariae mediae, wolf tail grass (ghost fork), salsola collina, elscholtiza (open country Soviet Union Son), purslane, pale persicaria, dayflower (orchid dish), Semen Cuscutae etc..Soybean Field perennial weeds mainly has sowthistle, meadow pine (section bone grass), field thistle (field thistle), setose thistle (cottonsedge-like thistle herb), reed, alkali grass etc..From in recent years, in most of China Area is all presented a kind of trend, dayflower, wolf tail grass, pale persicaria, Siberian cocklebur, black nightshade, bog marshcress herb, piemarker, sowthistle, field thistle, big The broadleaf weeds such as Ji have gradually replaced the gramineae weeds such as barnyard grass, wild avena sativa, herba setariae viridis and have become Soybean Field main weeds.It is small Ji, sowthistle, dayflower are more known as Soybean Field " three dishes ", become the difficult point that soybean weeds are prevented and kill off.Soybean Field chemistry removes Careless agent usage mode is generally taken and broadcasts preceding or soil treatment before seedling sowing and stem and leaf treatment after seedling two ways.Before broadcasting or after broadcasting It is management of weeds the advantages of soil treatment before seedling in the budding period and before causing damages, herbicidal effect is more stable, dispenser cost It is relatively low, even if management of weeds is bad compared with fruit, can also be remedied after seedling.Disadvantage: first is that pH value, by soil types, organic Matter content is affected, and is not suitable for when soil excessively glues weight, the content of organic matter is excessively high or pH value does not meet certain medicament using soil Earth processing;Second is that some herbicides such as metribuzin, 2,4-D butyl ester etc. are also easy to produce in sand soil, low-lying land due to the leaching of medicament Phytotoxicity;Third is that be affected by meteorological condition, especially spring arid, wind is big and abnormal low temperature or high temperature can all influence weeding effect Fruit.The advantages of stem and leaf treatment after seedling be influenced by soil types, the content of organic matter, soil moisture it is smaller, can be according to being unearthed The suitable herbicide with strong points of weeds type selection.Disadvantage: first is that in drought, air humidity is small and weed growth is slow Herbicidal effect is bad in the case where slow;Second is that some medicaments are also easy to produce phytotoxicity under the conditions of too high or too low for temperature;Third is that after seedling Cauline leaf process must just can be carried out when most of weeds are unearthed and have the leaf area of certain adhering liquid medicine, at this time soybean early period Growth is influenced by crop smothering, causes the underproduction.Therefore, Soybean Field chemical weed control is generally based on soil treatment, after seedling at cauline leaf Supplemented by reason., radix biggish plot more to weeds type needs to carry out secondary chemical weed control.Therefore Soybean Field chemical weed control, It flexibly to be grasped in implementation process, particular problem concrete analysis.Due to, soil property difference in all parts of the country is larger, and climate difference is significant, Increase the difficulty of soybean field weeding.
Soybean Field common weed is just like three-coloured amaranth, knotweed, Chenopodiaceae, black nightshade, Siberian cocklebur, barnyard grass, herba setariae viridis, herba digitariae, broomcorn millet etc..Sugarcane field is normal See that weeds there are the annual grassy weeds such as the rhizome of nutgrass flatsedge, herba digitariae, herba eleusines indicae, bald barnyard, bidens pilosa, Bermuda grass.Corn field is common miscellaneous Not only there are also perennial weeds for raw weeds one year in grass, but also these weeds have multiple out of grass, and difficulty of prevention and cure is big.Agriculture at present Phytotoxicity easily occurs for most-often used glyphosate, glufosinate-ammonium, the secondary monooctyl ester of fluroxypramide, Bi Kecao etc. in industry production.Simultaneously before major part Height is required to the careless age of weeds when stating Common Herbicides application, beyond a certain range of careless age, herbicidal effect is substantially reduced.Grass is sweet Phosphine, glufosinate-ammonium class herbicide are more only applicable to bare place weeding.Meanwhile weeds chemical herbicide will be generated it is different degrees of Resistance.These factors, all making herbicide need constantly to release, effect is more preferable, the wider array of new varieties of degrass spectrum.
Chinese patent (application number CN2013100125604, January 15 2013 date of application, Granted publication date 2014 On November 19) in report the general formula of the artificial Xihua Univ of patent application (inventor Yang Weiqing, Ma Menglin etc.) be TAM's (formula 3, X indicates halogen in formula 3 for the disubstituted thioacetyl amine compound of 2- pyridine acyloxy-N- and its synthetic method;Y is indicated Halogen;Z indicates branched alkyl).Chinese patent (application number CN2013100201913, January 21 2013 date of application, authorization Date of declaration September in 2014 3 days) in report the artificial Xihua Univ of patent application (inventor Yang Weiqing, Zhang Yuanyuan etc.) right General formula is that the novel synthesis of the disubstituted thioacetyl amine compound of 2- pyridine acyloxy-N- of TAM is reported, the new side Method uses ester-interchange method to the synthesis of target product, obtains very good effect.Chinese patent (application number CN2013100201928, Shen Please January 21 2013 date, March 26 2014 Granted publication date) in report the artificial Xihua Univ of patent application (hair Bright artificial Yang Weiqing, Zhang Yuanyuan etc.) general formula be TAM the disubstituted thioacetyl amine compound of 2- pyridine acyloxy-N- make For the purposes of herbicide, it is mainly used for preventing and kill off broadleaf weeds and gramineae weed in farmland.In the compound that general formula is TAM TAM-5(formula 4) activity of weeding is best, annual gramineae weed and broadleaf weeds can be effectively prevented and kill off, but it is more to part Year, raw weeds can only play limited inhibitory effect, and degrass spectrum is not extensive enough.In addition, the TAM-1 in the compound that general formula is TAM (formula 5) activity of weeding is also preferable, is only second to TAM-5, can also effectively prevent and kill off annual gramineae weed and broadleaf weeds, equally Limited inhibitory effect can only be played to part perennial weeds, degrass spectrum is not extensive enough.Meanwhile the life of TAM-5 and TAM-1 Produce cost for most of herbicide kinds currently on the market, slightly higher, economically consider, also it is necessary to Interworking use is carried out with other effective herbicides.
