Effect of Foliar and Drench Applications of Acetyl Salicylic Acid on Control of Rhizoctonia solani and on Dry Matter Production and Partitioning of Potatoes

Syed Karar Haider and Saifullah

ABSTRACT

Different concentrations of acetyl salicylic acid 1, 5 and 10 mM were applied through soil drench and foliar application at weekly intervals starting from emergence of the plants to investigate the effect of ASA on the control or Rhizoctonia solani and on general growth responses. Application of ASA did not influence the development of stem canker. Increasing concentrations of ASA produced reductions in tuber fresh weight and in total and component part dry weights. A concentration of 10 mM increased main stem numbers significantly, although this concentration was some what phytotoxic.
