Effect of Bio-Agents and Fungicides in Management of EAF Spot of Chilli (Capsicum annuum L.) Caused by Alternaria alternata (Fr.) Keissler

Abstract

The study entitled “Effect of bio-agents and fungicides in management of leaf spot of chilli (Capsicum annuum L.) caused by Alternaria alternata (Fr.) Keissler” was carried out during the rabi season of 2022-2023 at the Central Research Field, Department of Plant Pathology, Sam Higginbottom University of Agriculture, Technology & Sciences, Prayagraj. The experiment was carried out in Randomized Block Design (RBD). Among the treatments taken up for research Mancozeb (1g/L)+Carbendazim (1g/L for foliar spray) was found most effective against Alternaria alternata. The minimum disease intensity (11.21, 14.42 and 18.97) was obtained in Mancozeb (1g/L)+Carbendazim (1g/L as foliar spray). It can be concluded that foliar spray treatment of chilli with Mancozeb (1g/L)+Carbendazim (1g/L as foliar spray) recorded higher plant height (61.63), number of leaves per plant (184.60), number of branches per plant  (12.07), number of fruit per plant (55.93), fruit weight (g) (4.61), fruit yield (g) per plant (258.70),  fruit yield (g) per plot (1293.49)  and fruit yield (t ha-1) (6.47).
