A field experiment was conducted at TCRC, BARI, Gazipur during robi season of 2010-11 to evaluate the efficacy of manganese sulphate, zinc sulphate, potassium phosphonate and salicylic acid for the management of common scab in potato. Chemical solutions were applied as soil drenching or foliar spray. All the treatments significantly reduced scab severity as compared to control, however, application of manganese sulphate and salicylic acid were found effective in reducing potato scab in the field.

To evaluate the chemicals to manage potato scab.
This experiment was conducted in TCRC research field in Gazipur. Four treatments, such as, Manganese sulphate (0.3% w/v), Zink sulphate (0.3% w/v), potassium phosphonate (0.2% v/v) and Salicylic acid (1500 ppm) were evaluated. Experimental plots were 3mx3m in size. Potato seeds (variety Diamant) were planted in the last week of November with spacing of 60 cm row to row and 25 cm seed to seed. All cultural practices were done according to recommendation. When the crop reaches 30 days, chemical solutions, 5L of each, were applied three times at the base of plants in rows at 10 days interval. Potato was harvested timely. Scab incidence (%), severity (percent surface area) and yield were recorded. The experiment was laid down in RCBD with four replications. Data were analyzed by MSTAT-C program to get ANOVA. Mean separation was done using DMRT at 5% level of probability.
