Description
【Technical field】
The invention belongs to pesticide field.More particularly it relates to a kind of containing pyraclonil, acetamide-group herbicides the
Two active components and the Herbicidal combinations of the active component of sulfonylurea herbicide the 3rd, further relate to the Herbicidal combinations in preventing and treating
Application on paddy field weed.
【Technical background】
Paddy rice, annual gramineae plant, unifacial leaf, happiness high temperature, how wet, short-day, are also as grain in Oryza
Main most long one kind.Paddy rice is China the first generalized grain crop, and the species of paddy field weed is a lot, and various places weeds occur
Species is different, and national rice region there are about the kind of weeds more than 200, wherein common generation is universal, endanger serious main weeds there are about 40
Kind, occur with barnyard grass in main weeds and hazard area be maximum, be secondly difformed galingale herb, Monochoria vaginalis, flat stalk Fischer grass, moleplant seed,
Bog pondweed takes second place.Rice field weeds strive water, fertilizer, luminous energy with crop, occupy space above and below the ground, affect crop photosynthesis to make
With, plant growth is disturbed, reduce grain yield, it is also possible to induction and propagation pest and disease damage, increase farm production cost, affect people and animals
Health.
Pyraclonil (pyraclonil), No. CAS [158353-15-2], chemical name 1- (chloro- 4,5,6, the 7- tetrahydrochysene pyrroles of 3-

Pyraclonil be rice terrace herbicide, be German Schilling company (being now Beyer Co., Ltd) find with pyrazolo
The novel structure compound of pyridine ring, belongs to proporphyrinogen oxidase (PPO) inhibitor, to barnyard grass and simultaneous annual tool
Awns cyperus iria section firefly Lin, needle spikesedge herb, broad leaved weed Chinese herbaceous peony shape Monochoria korsakowii, Procumbent Falsepimpernel and wild arrowhead for many years, water chestnut etc. are wide
Scope weeds have very high activity.
Acetamide-group herbicides are the efficient preemergence herbicides of current widely used class low toxicity, because of its validity, are selected
Property, degradation speed it is fast and to the low distinguishing feature of higher mammal toxicity, and to including including paddy rice, cotton, potato and corn
The Weeds distribution of various Important Economic crops have broad application prospects.Use as the second active component in the present invention
Acetamide-group herbicides include but is not limited to pretilachlor, butachlor and fentrazamide.
Pretilachlor (Pretilachlor), No. CAS [51218-49-6], chemical name 2- chloro- N- (2,6- diethylbenzenes
Base)-N- (2- Amongs) acetamide, the product are amide-type preemergence herbicide.Product belongs to 2- acetyl chlorides and removes for phenyl amines
Careless agent, is cell division inhibitor, and for soil treatment barnyard grass in paddy field, difformed galingale herb, needle spikesedge herb, barnyard grass, narrow leaf pool can be prevented and kill off
Rush down.It is poor to perennial weeds preventive effect.Generally 3～5d is used before rice transplanting.
Butachlor (Machette), No. CAS [23184-66-9], the chloro- N- of chemical name N- (butoxymethyl) -2- (2,
6- diethyl phenyls) acetamide is amide-type selectivity Uptake and translocation herbicide.Sterling is pale yellow oily liquid, with micro-

Under the conditions of it can be accelerated to decompose, can be degraded in soil.To people and animals' low toxicity, there is stimulation to skin, eyes, it is high to fish
Poison.Butachlor is mainly absorbed by the young shoot of weeds, is then conducted complete stool and is worked.Can use with seedling stage before bud.Plant
After absorbing butachlor, suppress and destroy protease in vivo, affect the formation of protein, suppress weed bud and young root normally to give birth to
Long development, so that weeds are dead.To sprouting and weeds are effective before 2 leaf phases, it is adaptable to which barnyard grass is prevented and kill off in rice field, difformed galingale herb,
1 year raw grassy weed such as cyperus iria, moleplant seed, Niu Wang grass.
Fentrazamide (Fentrazamide), No. CAS [158237-07-1], chemical name 4- (2- chlorphenyls)-N- rings
Hexyl-N- ethyl -4,5- dihydros -5- oxygen -1H-TETRAZOLE -1- formamides.Fentrazamide is a kind of for grass and
The herbicide of year life sedge, it is more preferable to barnyard grass effect.
Sulfonylurea herbicide be a class efficiently, the herbicide of low toxicity.Its exploitation starts from phase late 1970s, development
It is exceedingly fast, occurs in that the multiple kinds for Different Crop field.At present such herbicide has been applied to various crop ground, some products
The herbicide govern-house-variety of some the crop fields, and new kind are become also in constantly commercialization.Conduct in the present invention
The sulfonylurea herbicide that 3rd active component is used includes but is not limited to bensulfuron-methyl, pyrazosulfuron and promazine Sulfometuron Methyl.
Bensulfuron-methyl (Bensulfuron methyl), No. CAS [83055-99-6], 2- (((4,6- dimethoxypyridins-
