Description
Technical field
It is water-soluble more particularly, to one kind 2,4-D salt the present invention relates to a kind of pesticide herbicide and preparation method thereof
Property granula and preparation method thereof.
Background technology
2,4-D is phenoxy carboxylic acid selectivity Uptake and translocation hormonal herbicide, and sterling is white crystal,
Solubility very little in water, is soluble in the organic solvents such as ethanol, benzene, but its sodium salt, ammonium salt are then highly soluble in water.
With stronger Uptake and translocation, in low concentration can as plant growth regulator, for prevent tomato,
The fruit drops such as cotton, pineapple and form s.m.p fruit etc., cauline leaf process be used in high concentration, can from root,
Stem, leaf enter in plant, and degraded is slow, therefore can build up to finite concentration, so as to disturb in plant swash
Element balance, destroys nucleic acid and protein metabolism, growing point is stopped growing, young leaflet tablet not tensible, suppression
System is photosynthetic to be normally carried out, and is transmitted to the medicament of plant bottom, promotes abnormal cell division, and the tip of a root is swollen
Greatly, absorbability is lost, stalk distortion, deformity is caused, screen casing is blocked, bast destruction, organic matter fortune
It is defeated to be obstructed, cause Plant death.2,4-D class herbicides can be used for the crop fields such as wheat, rice, corn, sugarcane
In, there is excellent preventive effect to broad leaved weeds such as lamb's-quarters, amaranth, knotweed, black nightshade, Siberian cockleburs.
The main formulations of 2,4-D are the missible oil of its esters and the aqua of its esters.Organic solvent in cream preparation
It is inflammable and environmental pollution can be caused larger, in addition, 2,4-D butyl esters volatile quantity when temperature is high is big in missible oil,
Easily diffusion drift, harm neighbouring dicotyledonous crops and trees, has been prohibited from using in many countries.And 2,4-D
Although salt aqua belongs to environmentally friendly formulation, but the aqua of high concentration easily occurs crystallization in low temperature,
Although low concentration aqua occurs crystallization, but increased packaging and cost of transportation, also limits to a certain extent
It has been made to use.
2,4-D salt preparations seldom add builder in preparation, and 2,4-D granules are in 2,4-D salt
On the basis of add filler be made, 2,4-D aquas are then that a certain amount of water system is added on the basis of 2,4-D salt
Into.2,4-D water-solubles granula for example disclosed in Chinese patent CN102578091A, including following weight
The composition of percentage：2,4-D salt (being counted with 2,4-D acid) 5-80%, water soluble filler surplus.Without addition
The aqua of builder is compared with the aqua of addition builder, and the surface tension of liquid is bigger, is difficult in target
Wetting, extravagance, infiltration are put on, few into the effective dose in weeds plant body, preventive effect is poor.
The content of the invention
The purpose of the present invention is exactly to provide a kind of quick-acting for the defect for overcoming above-mentioned prior art to exist
2,4-D water-soluble granulas with very big lifting and preparation method thereof.
The purpose of the present invention can be achieved through the following technical solutions：
2,4-D water-soluble granulas, are prepared using the raw material of following components and weight percent content：
2,4-D salt 10-81% (are counted) with 2,4-D acid, and builder 0.5-18%, water soluble filler is mended to 100%.
Preferably, 2,4-D water-solubles granula is using following components and the raw material of weight percent content：
2,4-D salt 40-80% (are counted) with 2,4-D acid, and builder 1-10%, water soluble filler is mended to 100%.
2,4-D salt is selected from isopropyl amine salt, ethylamine salt, monomethyl amine salt, dimethylamine salt, diethanolamine salt, three
One or more in ethanolamine salt, sodium salt, sylvite or ammonium salt.
Preferably, the preferred isopropyl amine salt of 2,4-D salt, diethanolamine salt or dimethylamine salt.
Builder is selected from AEO, APG, glycine betaine, APES
Or one or more in aliphatic acid polyethenoxy ether.
Water soluble filler is water-soluble inorganic salt or organic salt, selected from urea, sucrose, lactose, soluble shallow lake
Powder, sulfate, nitrate, hydrochloride, carbonate, bicarbonate, phosphate, phosphoric acid hydrogen disalt, phosphorus
One or more in acid dihydride salt.
Preferably, water soluble filler is urea, sucrose, lactose or soluble starch.
The preparation method of 2,4-D water-soluble granulas, 2,4-D salt, water soluble filler, builder are being pinched
In conjunction machine after full and uniform mixing, 2,4-D salt, water soluble filler, builder total amount 1-10wt% are subsequently adding
Water mediated, kneading finish after granulate, drying under the conditions of 20-90 DEG C.
Water soluble filler is only with the addition of in the prior art, and these water soluble fillers do not have surface-active, this patent
Builder is with the addition of, these builders have surface-active, the surface tension of liquid can be reduced, carried
Wetting on weeds blade face high, sprawl, permeate, so that the dose being efficiently entering in weeds body is improved, therefore
Drug effect is improve, the present invention has advantages below：
1st, production technology is simple, economical, safe：Whole production process does not use harmful influence, it is easy to control
And operation, safety coefficient is high.
2nd, water-soluble granule belongs to environmentally friendly formulation, with conventional missible oil, wettable powder, suspending agent
Compared to have the advantages that organic solvent-free, without dust, easily metering.
3rd, 2, the 4-D water-soluble granulas for preparing are easy to use, reduce packaging and carrying cost.
4th, 2, the 4-D salt water-soluble granules for preparing have excellent activity of weeding, can effectively reduce
The usage amount of 2,4-D salt, reduces use cost.
