FIELD TRIALS IN EGYPT WITH ACROLEIN  HERBICIDE-MOLLUSCICIDE.
Acrolein is a dual-purpose chemical effective against both submersed weeds and snails, and it may therefore be of significance in bilharziasis control. During trials in the Egypt-49-project area in 1962, it was effective in clearing heavy mats of the major submersed aquatic weed Potamogeton crispus from irrigation canals. The resurgence of snails to pretreatment levels was delayed by 8-12 months, and submersed weeds did not reappear until 8 months after treatment. In phytotoxicity tests on local crops, it was found that the concentration of acrolein required for destroying submersed weeds (20-25 ppm) had no adverse effect on the crops. The field tests showed that it is important to have complete control of the water during the period of application.
