Control of Synchytrium endobioticum with crabshell meal

In Canada, experiments were carried out to investigate the potential of crabshell meal to control Synchytrium endobioticum (EPPO A2 pest) on potato. Eight experiments were conducted over a time period of four years. Crabshell meal was obtained by drying and crushing crab legs (meat-free) or by utilizing a commercial product out of lobster and crab that included meat remains. In four of the experiments the disease was reduced up to 100% using the meat-free crabshell meal. Successful trials were those in which the meat-free meal was placed above the tubers at rates of 20-80 g meal per kg soil.
