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. The minimum disease index with 4.45 % were recorded in case of both tuber treatment and foliar spray with salicylic acid as inducer followed by calcium chloride as 4.87 % and boric acid as 5.35% against 9.52 % control-1 and 11.71 % control-2 after harvesting, respectively during 2017-18. The similar trend of observations have also been reported during 2018-19.As per yield is concerned, the highest yield (446.85 g per plant) was recorded from salicylic acid treated plant which is 74.21% and 83.26 %.increase over control-1 and control-2 in year 2017-18. The similar trends of observations have also been reported during 2018-19.Foliar spray with the inducers before pathogen inoculation, protected the plant against infection resulting reduce disease index.
