Abstract:
A method for preparing a stable, aqueous, fungicidal emulsion, consisting essentially of 2-(thiocyanomethylthio) benzothiazole (TCMand 3-iodo-2-propynyl-N-butylcarbamate (IPBC) in a TCMTB:IPBC weight ratio of about 0.03:1 to about 30:1 and a total weight percentage of TCMTB and IPBC, based or the total weight of emulsion, of about 10 to about 30%; a nonionic surfactant; a thickening agent; and a glycol having at least six carbon atoms and exactly two hydroxyl groups; comprising the steps of:(a) forming a homogenous blend of the TCMTB and IPBC;(b) providing the nonionic surfactant in a liquid state;(c) combining the honmogenous blend of step (a) with the nonionic surfactant of step (b), with stirring, to form a combination thereof;(d) wetting the thickening agent with the glycol; and(e) combining the wetted thickening agent of step (d), with the combination of step (c), with stirring, to form a homogenous emulsion.
