Abstract
The present invention relates to a synergistic imidacloprid series preparation, and is characterized by adding 0.1-20% of hypertonic adjuvant in the course of preparing preparation. When the synergistic imidacloprid preparation is used, as compared with non-synergistic imidacloprid its dose of unit area can be reduced by half.
Description
The present invention relates to a kind of process preparation of agricultural chemicals.It exactly is a kind of Synergistic imidacloprid series preparation.
Imidacloprid is novel organic heterocyclic insecticides, have low toxicity, efficient, wide spectrum, strong in characteristics such as suction.Be processed to the preparation used always such as pulvis, granule, emulsion etc. at present extensively with various crop such as paddy rice, cotton, corn, vegetables, fruit tree control rice fulgorid, leafhopper, thrips, aphids etc.
Because absorption is strong in the Imidacloprid, preventive effect good, so in preparation commonly used at present, do not added other auxiliary agents of synergistic effect.Such as pulvis is exactly that the former medicine of Imidacloprid constitutes with filler, and emulsion is exactly that the former medicine of Imidacloprid, solvent and emulsifier constitute.Such preparation per hectare consumption reaches 30 grams (active ingredient).
The present invention has added hypertonic assistant when process preparation, be intended to guarantee reduce under the prerequisite of preventive effect the consumption of unit are, reduces the control cost.
Principal character of the present invention is exactly to add the hypertonic assistant of a certain amount of synergistic effect when preparation processing.Described hypertonic assistant has screened following some kinds by experiment: maleic acid di-sec-octyl sodium sulfonate, sodium butylnaphthalenesulfonate, alkylbenzenesulfonate, dodecyl nitrogen cover ketone, secondary octanol APEO, aryl APEO, alkyl ether polyethers, Emulsifier EL-60, alkylaryl epoxides block polyether, alkylaryl resin polyethers etc.In experiment, more than some kinds of hypertonic assistants can use separately, also can be two or more mixing use, and under the prerequisite of control total amount (toatl proportion content), can mix mutually by arbitrary proportion between two or more.
Abbreviation LSC when for sake of convenience, hypertonic assistant occurring later on.
As follows to various preparation divisions:
1, Imidacloprid pulvis
Imidacloprid 0.1～50%
LSC????????????????????0.1～20％
Auxiliary agent 0.1～20%
The filler surplus.

3, Imidacloprid granule
Imidacloprid 0.1～50%
LSC????????????????????0.1～20％
Adhesive 0.1～20%
The carrier surplus.
Described adhesive can be polyvinyl alcohol or carboxymethyl cellulose.Carrier can be natural sand or clay or diatomite, float stone, sepiolite, dolomite, cinder, masonry, kaolin etc.
4, imidacloprid suspending agent
Imidacloprid 0.1～50%
LSC????????????????????0.1～20％
Its minute auxiliary agent 0.1～20%
Water surplus.
Described other auxiliary agents can be lignosulfonates or two methyl naphthalene sulfonic acid salt, xanthic acid, polyvinyl alcohol, carboxymethyl cellulose, white carbon, urea, alkylphenol polyoxyethylene, attapulgite, bentonite etc.Main play dispersion, thickening, effect such as antifreeze.
5, Imidacloprid liquor
Imidacloprid 0.5～50%
LSC????????????????????0.1～20％
The solvent surplus.
Described solvent can be water or DMF, methyl-sulfoxide, pyrrolidones, isophorone etc.
Use the Synergistic imidacloprid preparation to compare with non-Synergistic preparations, under the prerequisite of equal preventive effect, the consumption of unit are can reduce half.
Following table is the preventive effect comparison sheet of Anhui Dingyuan plant protection unit to rice fulgorid.
Annotate: numeral is 4 repetition means in the table.
