The preparation method of weeding water purification agent of the present invention mixes described solution component and get final product according to described ratio; Preferred preparation method is as follows:
1) get 20～42% paraquat solution 5-15 weight portion, under agitation add continuously 3～6% aluminum sulfate solution 3-7 weight portion;
2) until step 1) mixed solution stir after, add successively 10～25 parts of chloroacetic acid solution 10-25 parts of 5～10%, 4～7% potassium persulfate solution, 41% 20～40 parts of glyphosate solution, penetrating agent JFC 5-10 part, ferrous sulfate 5-10 part of 3～7%, detergent LS 3-10 part of 2～8% and sodium sulphate 5-7 part of 3～7%, stir and get final product.
Step 2) described glyphosate is selected from one or more the mixture in glyphosate, glyphosate isopropyl amine salt, glyphosate methylamine salt, ammonium glyphosate, sodium glyphosate or glyphosate potassium; Preferably glyphosate isopropyl amine salt.
Weeding water purification agent of the present invention can, for the preventing and kill off of the various weeds in land and waters, be particularly useful for preventing and kill off of waters weeds, wherein the fast weeds of the breedings such as weter hyacinth is had to significant preventive effect.
Weeding water purification agent of the present invention adopts spraying method to use conventionally, controls the concrete consumption that grass uses as follows:
Between field, get 100-130 milliliter weeding water purification agent of the present invention with controlling grass, be watered 15 kilograms;
Roadside, field is controlled grass and is got 120-150 milliliter weeding water purification agent of the present invention, is watered 15 kilograms;
150-200 milliliter weeding water purification agent of the present invention is got with controlling grass in pasture and water, forest land, is watered 15 kilograms.
In weeding water purification agent of the present invention, the effect of each component is specific as follows:
Paraquat is quick-acting contact killing type steriland herbicides, adopts the dispenser of cauline leaf spray-on process.After dispenser, in liquid, bipyridine cation is absorbed by axis, blade rapidly, in chlorenchyma, be reduced into bipyridyl free radical by photosynthetic and respiration, make water and oxygen in stem, leaf texture form hydrogen peroxide and peroxy radical through autooxidation again, this class material is extremely strong to chloroplast tunic destructive power.
Glyphosate is mainly by suppressing enol acetonyl shikimene phosphate synthase in plant corpus, thereby inhibition shikimene is to the conversion of phenyl alanine, tyrosine and tryptophan, makes synthetic being interfered of protein cause plant death.Glyphosate is strong and famous with interior suction conductivity, it can not only be transmitted under ground portion by cauline leaf, and also can conduct between the difference of same plant is tillered, very strong to the underground organization destructive power of perennial dark root weeds, can reach the general agricultural machinery degree of depth that is beyond one's reach.Glyphosate herbicide spectrum is very wide, and the plant of section more than 40 is prevented and kill off to effect, comprises the plants such as unifacial leaf and dicotyledonous, annual and perennial, herbs and shrubs.The better resistance of some plants of pulse family and Liliaceae to glyphosate.After glyphosate buries, be combined and lose activity with the metal ion such as iron, aluminium very soon.
Potassium peroxydisulfate, as oxidant use, not only has stronger oxidisability, simultaneously also relatively safe, is conducive to spray operation and transport storage.
Aluminum sulfate is usually used in sewage purification, it can with tag after weed killer herbicide in toxic molecule or heavy metal substance complexing form large molecule precipitation, effectively reduce the toxic of weed killer herbicide, prevent pollution of herbicide water body.
Monoxone is to have corrosive acidic materials, is usually used in weedicide, can play the effect of synergy erosion grass roots in weeding water purification agent of the present invention.
Ferrous sulfate can play the effect of water purification.
Penetrating agent JFC plays the effect of infiltration, can change the amphipathic property of this weed killer herbicide, in the time that the dilution of this weed killer herbicide is sprayed onto the pasture and water such as weter hyacinth surperficial, can not become the globule in surface condensation, and be shaped as leaf, the surface, footpath that moisture film fully covers pasture and water, bring into play to greatest extent effect, simultaneously in the time that active ingredient starts to corrode the interior tissue in leaf, footpath, penetrating agent JFC also can play immersional wetting, impels medicine to bring into play fully, rapidly drug effect.
Detergent LS can play pH and regulate the effect neutralizing.
Sodium sulphate is favourable rushes down the effects such as removing toxic substances.In this herbicidal composition, sodium sulphate can impel rapidly and not corrode and start leaf, the footpath tissue dewatering after corrosion, strengthens killing of active ingredient and does not have effect.
Paraquat can play the effect that destroys cured of plant; Glyphosate isopropyl amine salt is as controlling supplementing of careless active ingredient.
After above-mentioned various component combines with specific ratio, there is each other action effect collaborative, synergy, for weeding water purification agent of the present invention brings significant herbicidal effect.Wherein active ingredient paraquat, glyphosate and potassium peroxydisulfate can form coverlay on the smooth leaf of the pasture and water such as weter hyacinth, surface, footpath under the effect of penetrating agent JFC; adhesive force is stronger; potassium peroxydisulfate is the diaphragm on calcination corrosion surface, leaf footpath in a short period of time; thereby make paraquat and glyphosate that the interior tissue of the pasture and water such as weter hyacinth is destroyed and be corroded; sodium sulphate can be accelerated the dehydration death of leaf footpath tissue; sodium sulphate not only can dewater; the more important thing is and can solution poison malicious specific action, also can make the effectiveness of active ingredient more obvious.Weed killer herbicide is killing after pasture and water, aluminum sulfate and the ferrous sulfate harmful substance after can the weeding of complexing weed killer herbicide forms precipitation, can not pollute sprayed waters, can not cause any adverse effect to waters biology (fish) yet, there is good environment-friendly function.
Inventor found through experiments; get 120～150 milliliters of weeding water purification agents of the present invention and be watered 15 kilograms; be sprayed at the careless plant leaf surface of evil; all comparatively even up and down, and temperature 20 degree left and right under the prerequisite rain or shine not raining; just there will be fraction blade slightly to roll in 24 hours; also to have black patches to show, within 48 hours, just have 4-5 to become blade to roll, and blackspot piece are also large-area outstanding.3-4 days, blade face has part to transfer white xanthochorism to by ink speck bulk, and the obvious dehydration that partial blade also has is dried-up.Then 5-15 days, 80%-90% is with the not only dried-up flavescence in blade face of the harmful grass by upper, even stem, by green flavescence, turns black phenomenon.
The present invention is to waters weeds spraying effect highly significant, as an example of weter hyacinth example (note: weter hyacinth blade is dense especially, except adopting above-mentioned application process, needs to mend and execute medicine one time in 3-5 days), can be basic dead clean if temperature in 30 degree left and right, sprays rear 10-20 days weter hyacinth.
It is different that ground, opposite bank weeds are used rear effect, sprays rear weeds stem and turn black (referring on native surface) by part in green flavescence comb rake, and along with passage of time, just lodgingization body of weeds after 15-30 days, until thoroughly die.But the place of herbicide spraying also has new plant and grows (not being that former grass sends), suffices to show that and sprays after weeding water purification agent of the present invention, and soil property is not destroyed by residue.
