摘要：Field trials of acrolein for the simultaneous control of aquatic weeds and snails were conducted in the Sudan. Phytotoxicity studies at 25 and 50 ppm showed minor or no damage to furrow-irrigated crops, but flood irrigation of vegetable seedlings at 15 ppm was toxic. Effective downstream carriage of acrolein was demonstrated for a distance of 1.6 km at a concentration of 25 ppm. Planorbid snails (Bulinus and Biomphalaria) were almost completely eliminated (98-99% kills). All submersed aquatic weeds were destroyed.
