Chemical control of false rust of winged bean
10 protectant and 10 systemic fungicides were tested for activity against Synchytrium psophocarpi.Greatest inhibition of germination in vitro was obtained with Calixin M and Saprol at 50 mg a.i. dm-3. In a field trial, mancozeb, triforine, pyrazophos. captan, Brestan 60 and Calixin M significantly (P ? 0.05) reduced the percentage leaf area of winged bean infected with false rust, but there was no correlation between disease severity and yield. A significant increase (P ? 0.05) in pod and seed yield was obtained only in plots sprayed with Calixin M.
