摘要 |
The direct handling of acrolein for combating microbial, plant and animal parasites in water and soil is problematic owing to the potential risks posed by acrolein. According to the invention, an easy-to-handle acrolein-releasing composition is used, the acrolein being released at the site of use owing to contact with water. This composition contains (i) an acrolein acetal having a C1 to C6 alcohol with 1 to 4 hydroxyl groups and (ii) a chemically compatible acid which is soluble therein and has a pKs value of less than 4 and (iii) is anhydrous. A preferred composition contains as acetal 2-vinyl-1,3-dioxolane, as acid, anhydrous oxalic acid, fumaric acid or maleic acid or a mixture of mono and di(C1 to C3)alkylphosphate and additionally a non-ionic surfactant.
