Description
Technical field
The present invention relates to herbicide technology field, is more particularly to a kind of combinations of herbicides containing caprylic acid and glufosinate-ammonium
Thing and its application.
Background technology
Certain herbicide of single use has been difficult the harm for controlling a variety of mixed raw weeds.Therefore, the combination of herbicide is i.e. mixed
Increasingly attracted people's attention with/mixture.Important means of the combinations of herbicides in farmland weed chemistry prevention and control, in the crop fields
It is wide with bare place application.According to report glufosinate-ammonium with 2 first, 4 chlorine with 2：1 and 1：When 1 ratio is used with, synergy work is shown as to barnyard grass
With.Herbicide mixture can effectively prevent and kill off black nightshade, ox chickweed, green bristlegrass He a variety of bare place weeds such as Wang grass.
Glufosinate-ammonium is organic phosphates herbicide, belongs to the bionical cauline leaf process agent of natural disposition of going out.The development of careless money unicorn is with exploitation
Closely related with double third ammonia unicorns, double third ammonia unicorns are the three skin natural products of one kind of the separating-purifying from streptomycete fermentation liquid, double
Propylamine unicorn without activity of weeding, is degraded into glufosinate-ammonium and alanine with activity of weeding in plant in itself.Accordingly, Germany Chinese mugwort
Ge Fu companies successfully synthesize glufosinate-ammonium.Glufosinate-ammonium preparation is widely used prevents and kill off a variety of annual and perennial standing grain in bare place
Undergraduate course weeds and broad leaved weed.After glufosinate-ammonium suppresses plant GS, plant nitrogen metabolism is caused to lack of proper care, it is necessary to amino acid starvation, finally
The content of intracellular ammonia is caused to accumulate rapidly, chlorophyll disintegrates therewith, Plant death.After spraying glufosinate-ammonium 3-5 days, plant is fixed
The speed of Cq declines rapidly, and withered and yellow and downright bad symptom occurs in plant leaf blade, and plant is dead within 1-2 weeks.Since GS is close to photosynthetic system
System, therefore its herbicide effect unicorn sweeter than grass is rapid but slower than PSI inhibitor paraquats.Although grass inhibited bacteria by unicorn, plant and
The GS of mammal, but because it cannot enter the blood and brain tissue of mammal, therefore, grass is safety to mammal by unicorn
's.In view of this, the herbicide synergistic combination containing glufosinate-ammonium is developed to be of great significance.
Caprylic acid, also known as caprylic acid, molecular formula C8H16O2；Be widely present in nutmeg, lemon grass (Cymbopogon citratus), apple, coconut oil,
In grape wine, hops etc., caprylic acid can be obtained by being extracted with volatile fatty acid fractionating process from coconut oil.It is currently used primarily in system
Dyestuff, medicine, spices, plasticizer, lubricant, it is also possible to make preservative, fungicide etc..
Scientific and reasonable chemical herbicide mixture/mixed have expand herbicidal spectrum, improve herbicidal effect, reduce dosage,
Reduce poisoning, reduce residual, the features such as delaying and administering the generation and development of resistant weed, herbicide mixture/mixed is solution
The above problem it is most effective, have easily one of method.At present on caprylic acid and the Herbicidal combination of glufosinate-ammonium herbicide mixture
Thing and application there is no report.
