Objectives: Black gram Vigna mungo (Linn) is a highly prized pulse. It is widely cultivated in many tropical and subtropical regions of the world including India. Cultivation and production of black gram showed decreased trend in last few years mainly due to the incidence of diseases. The effective control of the disease with the application of fungicides is need of hour. The aim of the study was to evaluate Hexaconazole in vivo against leaf spot disease causing fungi on Vigna mungo.
Materials and methods: This experiment was conducted to examine the efficacy of Hexaconazole 5% Sc against Leaf spot (fungal disease) on Black gram caused by Cercospora canescens, Fusarium equisetti and Curvularia lunata in Black gram. Hexaconazole 5% Sc was used the concentration i.e. 400 ml/0.40 hectors and the same time airspora trapped by Tilak air sampler. The experiment was carried out during Kharif season-2013 and the experimental side exactly located on 190.04945’ latitude and 770.684476’ longitude.
Result: The results showed that Hexaconazole 5% Sc was highly effective in controlling the incidence of Leaf spot in Black gram. The spore concentrations of Cercopsora, Fusarium and Curvularia were decreases after spraying the Hexaconazole 5% Sc fungicides as compare to untreated black gram field.
Conclusion: Present investigation revealed that fungicide Hexaconazole 5% Sc is potent to control the leaf spot diseases on black gram caused by various fungi and enhance grain yield and quality of the seed.
