Abstract

Early blight of tomato caused by Alternaria solani is one of the major production constraints to tomato production, causing significant yield reduction and resulting in a severe economic impact. The objective of the current study was to assess the efficacy of different fungicides, plant extracts, and vitamins in managing the disease under both in-vitro and in field conditions. Different doses of fungicides (0.05%, 0.1%, 0.25%) and plant extracts (5%, 10%, 15%) were used for in-vitro evaluation employing the poisoned food technique. The results revealed that, among all the fungicides, (Antracol, Nativo 75%-WG, Topsin-M, Score, Ridomil gold, Champion) score (Difenoconazol) at 0.25% concentration and among all the botanicals (Ginger, Garlic, Kalonji, Ajwain) ginger at 15% concentration indicated maximum percentage inhibition of 62.85% and 48.48% respectively. However, thiamine among all the vitamins (Thiamine, Niacin, Pyridoxin) at 150mg/L concentration showed minimum (26%) disease incidence when evaluated under greenhouse conditions. While under field conditions score exhibited minimum disease incidence 15.19% among all the treatments. Overall findings revealed that weekly sprays of score at 0.25% concentration were found superlative for the management of early blight disease of tomato.
