The invention relates to new substituted 1-iodo-1-butyn-4-ols of the general formula, <IMAGE> in which R¹ is alkyl, optionally substituted aryl, aralkyl or aryloxyalkyl, R² is alkyl having more than one carbon atom, haloalkyl , optionally substituted cycloalkyl or aryl and, if R¹ is optionally substituted aryl, aralkyl or aryloxyalkyl, also represents methyl or R¹ and R² together with the carbon atom to which they are attached represent fluorene-9- yl stand, a process for their preparation and their use as plant protection products. The new 1-iodo-1-butyn-4-ols are obtained if suitable 1-butyn-4-ols are reacted with iodine in the presence of a basic compound. |
