The cultural filtrates of bio-control agents of B. subtilis, B. pumilus, T. harzianum, and T. virens; aqueous plant extracts of lantana, lemongrass, and olive cake; and citric acid could protect daughter potato tubers against bacterial soft rot disease in field application, except lemongrass (as soil treatment). The bio-control agents highly increased the activities of peroxidase, polyphenol oxidase, and chitinase enzymes, than other treatments. The bio-control agents also improved the shoot parameters, viz, shoot length, number of shoots/pit, and number of leaves/pit and yield parameters, viz, tuber weight/pit, tubers number/pit, and total tubers weight/pit, compared to citric acid a...
