Description
Technical field
The invention belongs to herbicide technology fields, and in particular to a kind of Gyphosate herbicice synergist containing ethephon (CEPHA),2-(chloroethyl) phosphonic acid and contain
There are the glyphosate-class herbicides of the synergist.
Background technique
Glyphosate is a kind of whole world use and the maximum herbicide of sales volume, in plant uptake and translocation it is strong and
It is famous, have the advantages that wide spectrum, natural disposition of going out, efficiently, low toxicity, low-residual and environmentally friendly, be widely used in farmland, fruit
A variety of annual, biennial and perennial weeds, filling are prevented and kill off in the places such as garden, forest land, park, road, river, plant area and warehouse
Wood, fern, algae etc..Since it is with particular mechanism of action, weeds are caused to generate resistance to it very slow, it is wide from 1974
Between general 20 years for being applied to 1993, never about the report of glyphosate-resistant weeds.However after 1996, with a system
The expansion of column transgenosis glyphosate resistant crops is planted, and the previous use pattern of glyphosate is revolutionized, start it is single and
Different growth and development stages, which are repeated as many times, before crop sprout and after sprouting etc. uses, and using more prevalent, dosage significantly increases glyphosate
Add, glyphosate is used for multiple times every year, no-tillage area is caused to expand.For depending on unduly and for a long time for same mechanism of action herbicide
It uses, weed community transition certainly will be will lead to and generates resistance, under selection pressure effect, weeds generate resistance or resistance to it
Property will significantly increase.
In recent years, glyphosate faces enormous challenge and pressure.Firstly, weeds produce resistance to glyphosate.Long-term
Under a large amount of high-intensitive selection pressure using glyphosate, have found that 28 kinds of anti-grass are sweet in the farmland of multiple countries and regions
Phosphine weeds, the rapid resistance rapid development of the weeds such as especially common Chenopodiaceae and amaranth.Such as the ivy glorybind in the wheatland of China North China, Tian Xuan
The dominant weeds such as flower, wartwort, the Conyza canadensis etc. of Ningbo of Zhejiang, the perennial weeds such as field thistle, meadow pine, lettuce pod dish in orchard,
It is no longer sensitive to glyphosate.Secondly, significant changes occur for weed community.Weeds under the selection pressure of glyphosate, although
Glyphosate resistance is continued to develop, but since there is differences to glyphosate-tolerant for different weeds, therefore weed population transition are than anti-
Property bion more frequently becomes apparent from.It is Conyza canadensis, thorn lettuce, summer cypress, grey in sweet potato field such as continuous application glyphosate 3 years or more
Ear amaranth, Chenopodiaceae, salsola collina etc. are increased, and in cotton field Soybean Field, amaranth, dayflower, knotweed, sweet potato, herba setariae viridis, piemarker and nutgrass flatsedge etc. are annual
Weeds become main weeds.Third, controlling weeds unit dose increase.Glyphosate bioactivity is high, and dosage is low, price and unit
One of the advantages of area use cost is low, is its sales promotion and uses.Dosage under normal circumstances, orchard, plantation have sprayed
50~100g/ of ingredient mus of effect, farmland sprays 20~80g/ mus of effective component, and forestry, road, garden or wasteland spray effective component
75~200g/ mus, add 15~40L of water, dilutes 200~300 times by spraying.But with the frequent use of glyphosate, weeds are sweet to grass
The patience of phosphine increases, and present dosage reaches original 3~8 times, even more than 8 of normal usage times or more, extension rate drop
As low as 100 times or less.By taking 41% glyphosate isopropylamine salt water solution as an example, 150~300 ml of dosage per acre, was used per acre now originally
Measure 200~900ml.4th, in production application, since herbicidal effect reduces glyphosate under conventional formulation rate, in order to
Improve glyphosate herbicidal effect, user arbitrarily with other herbicides or non-farm chemical ingredients mixture, arbitrarily increase dosage, change
Application method etc., leading to problems such as crop occur, phytotoxicity, person poultry poisoning, pollution environment, effect is poor occurs often.
In order to improve the herbicidal effect of glyphosate, reduce its dosage and cost, glyphosate preparation processing and make
With, needing to be added in the process some auxiliary agents, synergist.Glyphosate increases medicament and is planting by means of the effect of auxiliary agent, synergist
Adhesion, extension and permeability, ensure that effective component can smoothly enter in plant, are rapidly transmitted on object blade surface
Target site inhibits epsp synthase in plant, hinders the progress of plant biological process, is finally reached ideal weeding effect
Fruit.The main auxiliary agent of glyphosate is tallow amine polyoxyethylene ether, but it is to the irritating effect of people and animals, to aquatic toxicity compared with
Height, as the increase of application range and dosage is not suitable for anti-to weeds Developing Green for the effect decline of glyphosate tolerant crop
Control.Occurs its substitute products successively in recent years, such as glucose alkyl polyglycoside, organosilicon auxiliary agent, ammonium sulfate class, alkyl polyglycoside
Several classes such as class and glycine betaine.Most glyphosate assistants, synergist can all improve the activity of weeding of glyphosate to varying degrees, but
Its main function is defoaming, water quality adjustment, promotes deposition, diffusion, absorption, anti-drift, resistance of rainwater washing against etc. on weeds cauline leaf,
Majority acts on before medicament enters in plant.Enter in weeds body in glyphosate effective component, to glyphosate effective component
Weeds it is intracorporal dispersion, conduct to site of action, hinder physiological and biochemical procedure effect it is limited.
In order to overcome the problems, such as that glyphosate herbicidal effect in production application reduces, there is an urgent need to find a kind of synergist,
Glyphosate effective component can be improved in the intracorporal conduction of weeds, rate of dispersion, it is made quickly to be transmitted to target site, smoothly hindered
Disconnected weeds normal growth physiological activity improves glyphosate to the bioactivity of weeds is killed, to improve the weeding effect of glyphosate
Fruit.Using the synergist, the unit dose of glyphosate can be reduced under the premise of guaranteeing Gyphosate herbicice effect, it is sweet to improve grass
Safety of the phosphine to crop slows down generation of the weeds to the resistance of glyphosate, reduces glyphosate environmental pollution, to keep grass sweet
Phosphine is suitable for weeds Developing Green prevention and control.
