Abstract: The potential hazards of acraldhyde make its direct handling for combatting microbial, vegetable and animal pests in the water and ground difficult. According to the invention, use is made of a composition releasing acraldhyde in contact with water at the point of use. The composition of the invention contains an acraldehyde acetal, preferably 2-vinyl-2, 3-dioxolane, and a compound hydrolysable to an acide with a pKs of lower than 4, especially one from the range of organic acid anhydrides, organic acid halides and inorganic halogen compounds forming hydrogen halides on hydrolysis.
