In – Vivo Evaluation of fungicides for the management of stemphylium blight disease of garlic

Garlic commonly known as ‘Lasan’ is the 2nd important crop grown and used as a condiment, next to onion in India. Among the different fungal diseases of garlic, stemphylium blight has currently become one of the most important diseases of all garlic varieties. Diseases in the garlic is becoming the major limiting factor for its production and storage losses due to disease has been varying on different factors. Therefore, the present investigation is undertaken for the management of stemphylium blight disease in garlic. Combined fungicides were evaluated for their effectiveness under in vivo conditions. Field trial was conducted for two consecutive years during rabi season 2020-21 and 2021-22 on garlic variety Agrifound White. The experiment was conducted at Regional Research Station, National Horticultural Research and Development Foundation, Nashik, Maharashtra. The data were evident that treatment T4 (Azoxystrobin + Cyproconazole @ 1.0ml/L at 45, 60 and 75DAP) performed superior with the lowest incidence (32.50 %) and intensity (5.05 %) of stemphylium blight as well as 58.77% disease control of stemphylium blight over untreated control at 75 DAP. The significantly highest gross yield (65.27q/ha) as well as marketable yield (62.82 q/ha) was also recorded in T4.
