Efficacy of medicinal plant leaves against wilt of gladiolus caused by Fusarium oxysporum f. sp. gladioli

Abstract

An experiment entitled “Efficacy of Medicinal Plant Leaves against wilt of Gladiolus caused by Fusarium oxysporum f. sp. gladioli” was conducted at the Plant Pathology Section, College of Agriculture, Nagpur. A pot culture experiment was conducted in Factorial Completely Randomized Design (FCRD) with two main treatments (Pusa Suhagin and Punjab Dawn) and six subtreatments medicinal plant leaves, viz., Sitaphal, Beshram, Kaner, Marigold and (Carbendanzim + Mancozeb), and an uninoculated control in three replications during the rabi season 2023-24. The observations were recorded at 30, 60, 90, and 120 DAP. In the in vivo experiment, it was clearly observed that Carbendanzim + Mancozeb fungicide treatment was significantly superior, minimizing mortality (00.00%), and also increased shoot length plant-1 (65.45 cm at 120 DAP), higher spike length plant-1 (87.41 cm), maximum number of leaves plant-1 (8.57 at 120 DAP), number of shoots plant-1 (2.54), number of flower spike-1 (9.33), number of corm plant-1 (37.235) and weight of corm (37.27 g). Pusa Suhagin minimized the mortality (2.78%), as well as increased shoot length plant-1, spike length plant-1 (75.83 cm), number of leaves plant-1 (7.82), number of shoots plant-1 (2.195), and number of flower spike-1 (6.95). The interaction due to varieties and medicinal plant were found to be non-significant in respect of number of shoots plant-1, number of corms plant-1, number of leaves plant-1 and fresh weight of corms plant-1.
