Description
Technical field：
The present invention relates to herbicide technology field, and in particular to a kind of herbicide for expanding glyphosate weed control spectrum.
Background technology：
Glyphosate (glyphosate), it is the herbicide developed by Monsanto Chemicals, also known as：Glyphosate, agriculture reach
(Roundup), the dry phosphine of grass, phosphine sweet acid；Chemical name N- ((phosphonomethyl)) sweet ammonia, molecular formula：C3H8NO5P.
Glyphosate technicals content is generally 95~98%, and glyphosate technicals are white solid, not soluble in water, but and isopropyl
The alkali substance reactions such as amine are fine into water solubility after salt.41% most widely used gyphosate solution is exactly that grass is sweet currently on the market
Aqua made of phosphine, isopropyl amine salt, its glyphosate content are 30%, and isopropyl amine salt content is 41%, and mother liquor is usually
62% glyphosate isopropyl amine salt mother liquor.
Glyphosate is the chronic wide spectrum steriland herbicide of inner sucting conduction type, main to suppress enolpyruvyl thick grass in organism
Plain phosphate synthase, so as to suppress conversion of the shikimene to phenylalanine, tyrosine and tryptophan, make the synthesis of protein by
Interference causes Plant death.Glyphosate is to be transmitted to plant parts after being absorbed by cauline leaf, can prevent and kill off unifacial leaf and Shuangzi
The plant of the sections more than 40 such as leaf, annual and perennial, draft and shrub.Glyphosate can be used for preventing and kill off apple orchard, peach garden, grape
Garden, theatre, tea place, mulberry field and farmland fallow land weeds.Glyphosate bury after quickly with the metal ion such as iron, aluminium with reference to and lose
Activity, the seed and edaphon hidden in soil is had no adverse effects.
FenoxapropPethyl, belong to heterocyclic oxy group phenoxy propionic acid class herbicide, mainly synthesized by suppressing aliphatic acid
The acetyl-CoA carboxylase of key enzyme one, so as to inhibit the synthesis of aliphatic acid.Medicament passes through cauline leaf Assimilation and conductivity to separate living tissue
And the growing point of root, effect is rapid, stops growing within 2-3 days after dispenser, and 5-6 days lobus cardiacus chlorosis become purple, and separate living tissue becomes brown,
Blade is gradually withered, is the extremely strong cauline leaf process agent of selectivity.Be mainly used in Control Wild oat, amur foxtail, green bristlegrass, oat,
Rye grass, annual bluegrass, barnyard grass, spontaneous corn, lady's-grass etc..
Although above-mentioned two kinds of herbicide glyphosates, fenoxapropPethyl herbicidal effect are good, it is widely used, in practical application
In, the flaws such as preventive effect is insufficient, weeding is not thorough still be present, have much room for improvement.
The content of the invention：
The technical problems to be solved by the invention are, for above-mentioned prior art, for glyphosate single dose or compounding
The defects of preventive effect of preparation is insufficient, and weeding is not thorough, the invention provides a kind of herbicide for expanding glyphosate weed control spectrum, it is removed
Careless effect is good, broad weed-killing spectrum.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of herbicide for expanding glyphosate weed control spectrum, its active ingredient are glyphosate, fenoxapropPethyl
Dosage is as follows：Glyphosate 20~70%, Quizalotop-ethyl 1~20%, the number are weight percentage.
Preferably, glyphosate, fenoxapropPethyl, the dosage of the two are as follows：Glyphosate 30~70%, fenoxapropPethyl
5~15%.It is further preferred that glyphosate, fenoxapropPethyl dosage are as follows：Glyphosate 40~60%, fenoxapropPethyl 5
~10%.
The glyphosate is selected from glyphosate technicals, ammonium glyphosate, glyphosate potassium, sodium glyphosate, glyphosate isopropyl
One kind in amine salt, glyphosate dimethylamine salt is appointed several.
The herbicide for expanding glyphosate weed control spectrum, in addition to active ingredient, can also add surfactant, carrier
Or/and auxiliary material etc. is made aqua, aqueous emulsion, wettable powder, soluble powder, water dispersible granules, aqueous suspension agent or oil and suspended
Agent.Preferably, oil-suspending agent is made.During preparation, required formulation is prepared into according to common process.
The surfactant is selected from APG, tallow amine analog assistant, calcium dodecyl benzene sulfonate, dodecyl sulphate

The beneficial effects of the invention are as follows：
1st, by the compounding between two kinds of herbicides, using glyphosate cauline leaf uptake and translocation effect, fenoxapropPethyl
Cauline leaf is tagged, the different mechanism of root Uptake and translocation combine so that the herbicide has obvious synergistic effect, and expands herbicide
Spectrum, it is more preferable to some malignant weed preventive effects.
2nd, fenoxapropPethyl can effectively prevent and kill off grassy weed, and traditional formulation is missible oil, environmental protection and safety etc. be present
Problem, the present invention compound the two, by being screened to different auxiliary agents, make the aqueous suspension agent for meeting state quality standard, make two
Person is reasonably combined, produces synergy, reaches synergy.
3rd, by reasonably compounding, preventive effect is improved than traditional single dose, reduces effective ingredient consumption, and without organic molten
Agent, reduce production cost.Three compounds, and peasant is easy to use, there is higher cost performance.
4th, the present invention mainly use authorized by state safety and environmental protection formulation-aqueous suspension agent, it is environmentally friendly, without pollution compared with
Big organic solvent；And broad weed-killing spectrum, efficiency time length, reduce dosage and times for spraying, environmental pollution very little.

Test process and method：Perennial weeds region outside plant area's enclosure wall carries out the test of pesticide effectiveness, dispenser on July 5, applies
Medicine period is the weed growth busy season, and spraying equipment is 15Kg knapsack sprayers, and spraying is uniform, sets blank test to compare, examination
Test and set 7 processing (see above-mentioned), be repeated twice, totally 14 cells, the ㎡ of plot area 15,30Kg is watered to each medicament according to every mu
And clear water control treatment, test block is sprayed.
Observed and recorded after dispenser, 7 days after medicine, estimate within 14 days the preventive effect for managing area weeds everywhere, record weeds quantity, take per small
The average every square metre of weeds amount of survival in area, calculate the preventive effect of each medicament.
Preventive effect calculates：Preventive effect (%)=(blank district weeds-cell residue weeds)/blank district weeds * 100.
7 days after medicine, 14 days each trial zone preventing weeding weeds effects are as shown in table 4, table 5：
7 field management of weeds situation after the dispenser of table 4
14 field management of weeds situation after the dispenser of table 5
Contrasted by the test of pesticide effectiveness, it is known that, herbicide of the invention is due to have selected glyphosate, both fenoxapropPethyls
Compounding, interior suction and mechanism combination of tagging, hence it is evident that better than the use of single dose, and expand herbicide controlling spectrum, improve quick-acting, reduce
Dosage and cost, reduce the pollution to environment.
