Description
Technical field
The present invention relates to a kind of weeding class composition pesticides, especially for wheat paddock, Soybean Field and tomato, capsicum,
The vegetable farm herbicides such as potato, nursery leek, pimento, eggplant, semen viciae fabae, pea, onion.
Background technique
Isoproturon is initially to be developed by French Rhone-Poulenc company in the beginning of the seventies in last century, Full Name in English N,
N-dime- thyl-N-[4- (1-methylethyl) phenyl] urea, English abbreviation Isoproturon, experiment code name are
LS69-1299.Isoproturon Chinese chemical name is known as N, N- dimethyl-N-(4- isopropyl phenyl) urea, molecular formula C12H18N2O,
CAS 34123-59-6, structural formula are as shown in Equation 1.Isoproturon raw medicine appearance is white powdery solids, fusing point 158-159
DEG C, under the conditions of 25 DEG C, it is not dissolved in water (0.07 g/L, 25 DEG C), methanol (56 g/L, 25 DEG C), acetone (82 g/ can be dissolved in
L, 25 DEG C), a variety of organic polar solvents such as methylene chloride (63 g/L, 25 DEG C).But solubility is smaller in low polar solvent: benzene
(6 g/L, 25 DEG C), n-hexane (0.2 g/L, 25 DEG C).Isoproturon as inner sucting conduction type processing soil treatment agent and cauline leaf process agent,
Chenopodiaceae, annual bluegrass, the annual grassy weeds such as herba digitariae, to crop safety can be prevented and kill off.After plant root absorbs isoproturon inorganic agent, transporting is simultaneously
It is accumulated in blade, inhibits photosynthesis, cause weeds withered.Isoproturon system phenyl ureagroup herbicides are photosynthesis electronics
The inhibitor of transmitting interferes photosynthetic progress, cannot release oxygen and carbon dioxide under light illumination, and organic matter, which generates, to be stopped,
Susceptible weeds are withered because of starvation.Isoproturon is different from other hormone like herbicides, the environment not light reception intensity of generation effect
It influences, or even at a fairly low temperature still effectively.This feature of isoproturon is actually also a double-edged sword, and there is also one for it
A significant drawback, be easy to generate freeze injury phenomenon to plant: especially sensitive to wheat, there are jelly phytotoxicity, (isoproturon can reduce wheat
Freezing tolerance, after application meet serious frostbite be easy to happen jelly phytotoxicity, phytotoxicity degree increases with the increase of formulation rate, control it is different
Third grand dosage, which advantageously reduces, freezes phytotoxicity risk), when especially application phase temperature is low, application isoproturon is wanted and is paid attention in cold tail
Warm head application, does not occur daily minimal tcmperature for 1 week or so in 2 DEG C of weather below after guaranteeing application.Isoproturon is to spring wheat field one
Year raw weeds significant effect and to crop safety.Isoproturon can prevent and kill off annual grassy weeds, such as herba digitariae, Chenopodiaceae, annual bluegrass, amur foxtail
Deng being mainly used for wheat paddock, Soybean Field and tomato, capsicum, potato, nursery leek, pimento, eggplant, semen viciae fabae, pea, green onion
First-class vegetable farm herbicide.For isoproturon there is also a feature, half-life period is longer, has researcher once to carry out half with laboratory loamy soil
Decline phase experiment, and measurement isoproturon half-life period is 20 days, and the comparative experiments under similarity condition shows 2,4- drop and atrazine
Half-life period is respectively 3 days and 36 days.Isoproturon toxicity is smaller, and effect on environment is not significant.Acute toxicity: LD50=3350mg/kg
(mouse oral)；LD50=3600mg/kg(rat oral), while any stimulation is not generated to test animal skin and mucous membrane and is made
With.Subacute toxicity: it is fed with rat 3 months with the food of 400ppm concentration, without any symptom, and more than the observation period 2 weeks
Also without any symptom of discovery；The concentration that toxicity is not presented for 3 months in feeding dog is no more than 100ppm.In addition, isoproturon is to water
There are certain risks for lively object: belonging to low toxicity to trout and catfish.Therefore, because being deposited in isoproturon single variety preparation use process
Undesirable to big weeds effect of careless age, and it is easy the problems such as phytotoxicity is generated to certain industrial crops, therefore isoproturon can be with
It is used with other mixture of herbicides, so as to further expansion degrass spectrum.
It is more to its synthesising process research although isoproturon structural formula is relatively easy, according to using the primary raw material can be with
It is roughly divided into following five kinds of synthesis technologies.Process one (and initial synthesis technology, phosgene technique): with cumic aldehyde
Amine is that starting material and phosgene react generation intermediate 4- cumene isocyanic acid, intermediate 4- cumene isocyanic acid into
One step and dimethylamine carry out condensation reaction and obtain isoproturon, and due to the use of hypertoxic phosgene, production process is absolutely unsafe, this method
It has basically been eliminated at present；Process two (urea technique): being starting material and urea in strong acid (salt using cumidine
Acid) under the conditions of carry out reaction generate intermediate 4- isopropyl phenyl urea, intermediate 4- isopropyl phenyl urea further with dimethylamine
It carries out condensation reaction and obtains isoproturon, due to the use of a large amount of concentrated hydrochloric acids, production process is larger to equipment corrosion, while concentrated hydrochloric acid
It finally neutralizes and generates a large amount of inorganic salts solid sodium chlorides；Process three (N- replaces three chloroethene phthalein amine techniques): with p-isopropyl
Aniline is that starting material carries out reacting generation intermediate p-isopropyl tribromo-acetyl aniline with trichloro-acetic chloride in anhydrous conditions,
Intermediate p-isopropyl tribromo-acetyl aniline further with dimethylamine in DMSO as solvent, it is sodium hydroxide catalyzed in inorganic strong alkali
Under the conditions of, it carries out condensation reaction and obtains isoproturon, since dimethyl alum is expensive, only applied in laboratory research；Work
Process four (triphosgene, and the improvement to initial optical self-encoding technique): using cumidine as starting material with
Triphosgene (BTC) carry out reaction generate intermediate 4- cumene isocyanic acid, intermediate 4- cumene isocyanic acid further with
Dimethylamine carries out condensation reaction and obtains isoproturon, and due to the phosgene without using severe toxicity, production process safety is significantly improved, the party
Method has become the main synthesizing mean of isoproturon at present；This method has a distinguishing feature: being easy to generate diaryl urea
By-product can inhibit the generation of the by-product in production process very well using anti-dripping method.(the methylchloroformate work of process five
Skill): react with methylchloroformate generating intermediate cumidine formic acid first as starting material using cumidine
Ester, intermediate cumidine methyl formate further carries out condensation reaction with dimethylamine and obtains isoproturon, due to not using
The phosgene (and comparatively safe triphosgene) of severe toxicity, while also without isocyanate intermediate process, this method is in safety
Property aspect have very big advantage, therefore after completely solving cost and quality problem, which has biggish potential answer
Use feasibility.
Wheat paddock, Soybean Field and tomato, capsicum, potato, nursery leek, pimento, eggplant, semen viciae fabae, pea, onion etc.
Field of vegetables has numerous weeds.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 gramineous weed, annual broadleaf weed and perennial weeds.Soybean Field annual gramineous weed mainly have barnyard grass,
Herba setariae viridis, setaria glauca, wild broomcorn millet, herba digitariae, wild avena sativa etc..Soybean Field annual broadleaf weed mainly has Amaranthus retroflexus, Siberian cocklebur, black nightshade
(black star), acalypha copperleaf, Chenopodiaceae (Chenopodium album), bog marshcress herb, piemarker, water spine pin, willow leaf thorn smartweed, herba stellariae mediae, wolf tail grass (ghost fork), pig hair
Dish, elscholtiza (wild perillaseed), purslane, pale persicaria, dayflower (orchid dish), Semen Cuscutae etc..Soybean Field perennial weeds is main
There are sowthistle, meadow pine (section bone grass), field thistle (field thistle), setose thistle (cottonsedge-like thistle herb), reed, alkali grass etc..From in recent years,
A kind of trend, dayflower, wolf tail grass, pale persicaria, Siberian cocklebur, black nightshade, bog marshcress herb, piemarker, lettuce is all presented in most of China area
The broadleaf weeds such as Mai dish, field thistle, setose thistle have gradually replaced the gramineae weeds such as barnyard grass, wild avena sativa, herba setariae viridis and have become soybean
Field main weeds.Field thistle, sowthistle, dayflower are more known as Soybean Field " three dishes ", become the difficult point that soybean weeds are prevented and kill off.
Soybean Field chemical herbicide usage mode is generally taken and broadcasts preceding or two kinds of sides of soil treatment before seedling sowing and stem and leaf treatment after seedling
Formula.The advantages of broadcasting preceding or soil treatment before seedling sowing is management of weeds in the budding period and before causing damages, and herbicidal effect compares
Stablize, dispenser cost 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, the content of organic matter are affected, when soil excessively glues weight, the content of organic matter is excessively high or pH value does not meet certain medicament
It is not suitable for using soil treatment；Second is that some herbicides such as metribuzin, 2,4-D butyl ester etc. are in sand soil, low-lying land due to medicament
Leaching be also easy to produce phytotoxicity；Third is that be affected by meteorological condition, especially spring arid, wind is big and abnormal low temperature or high temperature all
It will affect herbicidal effect.The advantages of stem and leaf treatment after seedling be influenced by soil types, the content of organic matter, soil moisture it is smaller,
It can be according to the suitable herbicide with strong points of weeds type selection that has been unearthed.Disadvantage: first is that small in drought, air humidity
It is bad with herbicidal effect in the slow situation of weed growth；Second is that some medicaments are also easy to produce medicine under the conditions of too high or too low for temperature
Evil；Third is that stem and leaf treatment after seedling must just can be carried out when most of weeds are unearthed and have the leaf area of certain adhering liquid medicine,
Soybean early growth at this time is influenced by crop smothering, causes the underproduction.Therefore, Soybean Field chemical weed control is generally with soil treatment
It is main, supplemented by stem and leaf treatment after seedling., radix biggish plot more to weeds type needs to carry out secondary chemical weed control.Therefore soybean
Field chemical weed control will be grasped flexibly in implementation process, particular problem concrete analysis.Due to, soil property difference in all parts of the country is larger,
Climate difference is significant, increases 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, Acetochlor, Bi Kecao etc. in industry production.It is most of simultaneously aforementioned common
Height is required to the careless age of weeds when herbicide is administered, beyond a certain range of careless age, herbicidal effect is substantially reduced.Glyphosate, grass
Ammonium phosphine herbicide is more only applicable to bare place weeding.Meanwhile weeds will generate different degrees of resistance to chemical herbicide.
These factors, all making herbicide need constantly to release, effect is more preferable, the wider array of new varieties of degrass spectrum.
