Description
Technical field
The invention belongs to agrochemicals fields, are directed to more particularly, to one kind and solving the problems, such as that rice terrace annual grassy weeds is prevented and kill off
Herbicidal combinations.
Background technology
Diflufenican (diflufenican) belongs to acetamide-group herbicides, and the mechanism of action is herxheimer-liked reaction
Inhibitor, carotenoid content declines in processed plant, and then chlorophyll is caused to be destroyed, membranolysis, weeds table
It is now that young shoot decolourizes or bleaches.Application can form the medicine soil layer of anti-leaching in upper table before weeds germinate.It is entirely grown in crop
Phase keeps activity.When weed germination, medicament can be absorbed by young shoot or root system, finally result in death.It is retained in paddy field
In the case of, there is good preventive effect to barnyard grass, Monochoria vaginalis, rhizoma alismatis etc..
Pretilachlor (pretilachlor) belongs to chloroacetanilide herbicides, is mainly inhibited by hindering protein synthesis
The growth of cell.Medicament can be absorbed by plant hypocotyl, mesocotyl and plumule, and root slightly absorbs, and damage symptoms are
Acrospire is not unearthed or is stretched out from bud scale side, and distortion is unable to normal extension, and growth and development stops, until dead.To field barnyard grass
The annual gramineous weeds such as grass, lady's-grass, moleplant seed have good sealing process, and remove part annual broadleaf weed and Sha
Careless section weeds.
Penoxsuam (penoxulam) belongs to triazolopyrimidine sulfonamides herbicide, and the mechanism of action is acetolactic acid
Synzyme (ALS) inhibitor can be absorbed through cauline leaf, young shoot and root system, be conducted to separate living tissue, suppression by xylem and bast
Plant strain growth processed makes plant necrosis, death.Suitable for direct-sowing dry field, direct-sowing rice, rice seedling bed and the seedling throwing field of rice, rice transplanting
Cultivation field.Insecticide-applying way can be used spraying or mix native processing.Penoxsuam is rice field broad-spectrum herbicide, can effectively prevent and kill off barnyard grass
Grass, moleplant seed and annual sedge weed, and it is effective to numerous broad leaved weeds.
Clomazone (Clomazone) belongs to heterocycle herbicide, can be absorbed by the root of plant and seedling, can inhibit sensitive
The generation of plant chlorophyll and plamochromic pigment accumulation are interrupted, generate albinism, the Hill reaction in inhibiting weeds photosynthetic,
Make grass cutting blade tip and edge chlorisis, the withered death of the last whole strain of weeds.It can be used for rice terrace and prevent and kill off annual gramineae
And broad leaved weed, there is preventive effect to weeds such as barnyard grass, eleusine indica, lady's-grass, Setaria glauca, purslane, Monochoria vaginalis, and to for many years
Raw field thistle, setose thistle etc. also has stronger inhibiting effect.
Mesotrione (mesotrione) belongs to p-hydroxybenzene pyruvic acid (HPP) ester dual oxide enzyme inhibitor (HPPD inhibitor).
Mesotrione is a kind of for before seedling and seedling rear defence removes the herbicide of corn ground weed, herbicide controlling spectrum to be very wide, can prevent and kill off barnyard grass,
A variety of weeds such as lady's-grass, black nightshade, Tong fiber crops, Siberian cocklebur.
Pyraclonil (pyraclonil) belongs to novel double pyrazole class herbicide for paddy field, and the mechanism of action is protoporphyrinogen oxygen
The inhibitor for changing enzyme, is a kind of contact killing type herbicide.All kinds of weeds, including barnyard grass, difformed galingale herb, arrowhead, duck can effectively be prevented and kill off
Tongue grass etc. and the weeds resistant to sulfonylurea herbicide.
Furans sulphur humulone (tefuryltrione) is HPPD inhibitor, with existing sulfonylurea, steroids and amides
Cross resistance is not present in herbicide for paddy field, is suitble to the improvement of resistant weed.It is mainly used for preventing and kill off rice terrace triquetrousc murdannia herb, field soap
The weeds such as angle, bur beggar-ticks, Monochoria vaginalis, Procumbent Falsepimpernel, Herba Cyperi Glomerati.
Pyriftalid (pyriftalid) belongs to pyrimidinylthiobenzoate herbicides, and inhibitor of acetolactate synthetase passes through
Cauline leaf absorbs, and after plant intracellular metabolite, generates the best metabolin of drug effect, and through Uptake and translocation, weeds is made to stop growing, after
And it is withered, being mainly used for rice field prevents and kill off rice terrace annual gramineous weed, sedge weed and part broad leaved weed, to rice
Succession crop safety.
Benzobicylon (benzobicylon) belongs to double-octane class herbicide, and the mechanism of action is para hydroxybenzene benzylacetone
Acid esters dual oxide enzyme inhibitor.The compound can effectively prevent and kill off barnyard grass, Monochoria vaginalis, Procumbent Falsepimpernel, arrowhead, rain to rice safety
The rice terraces malignant weeds such as long flower, flat stalk Fischer grass.
There are different degrees of defects on control of weeds for herbicide kind containing single-activity component, after being used continuously
The problems such as weeds easy to produce drug resistance, and herbicide controlling spectrum narrows, causes environmental pollution.
Rationally compounding is to improve preventive effect, expand herbicide controlling spectrum, widen usage time to herbicide, delays shift of weed community
Speed, reduce resistance risk caused by pesticide single use, mitigate pollution to environment, reduce use cost and mitigate and remove
A kind of careless remaining effective ways of agent.
