Abstract:
Common scab caused by Streptomyces scabies (Thaxter) Waksman & Henrici is an important disease worldwide, and can cause significant reduction in the economic value of potato. The management of the disease can be done through conventional methods, biological chemical and cultivation of resistant variety. However, resistance against pathogen is not a permanent solution and fungicidal is not ecofriendly and economical. But new search, induce resistance has taken great attention for plant disease management in near future. Therefore, inquest for induce defense by certain inorganic chemicals like Salicylic acid (10mM), Calcium chloride (10 mM), Hydrogen peroxide (10 ppm), Boric acid (0.1%), Di-potassium hydrogen orthophosphate (0.2 %), Ferric chloride (5mM), Indole acetic acid (1 %), and Copper chloride (10 mM) as inducer were assessed during the course of present investigation. Tuber treatment with inducing agent provide good protection against common scab disease caused by S. scabies and also stimulate the germination of seed. Growth promoting effects of the inducers were also perceived salicylic acid treated plant showing maximum plant height of 5.20, 16.35, 29.10, 37.85 and 44.75 cm during 2017-18 and 5.35, 16.67, 30.28, 38.43 and 46.15 during 2018-19 at 10, 20, 30, 40 and 50 days age of seedling, respectively against 2.26, 11.90, 19.35, 26.15 and 29.35 cm and 2.47, 12.15, 20.91, 28.33 and 30.67 cm, respectively in case of control. Similarly all the growth parameters like covered area in cm, number of leaves per plant, number of branches per plant, stem diameter in cm etc. also found maximum in Foliar spray with the salicylic acid as inducers before pathogen inoculation, protected the plant against infection resulting reduce disease index.
