Evaluation of fungicides in vitro

Potato dry rot disease (Fusarium spp.) is one of the most important fungal storage rots on potato tubers after harvesting. The aims of this study were to identify the Fusarium species that cause dry rot in potato storages, evaluate the most virulent Fusarium species in vitro and in vivo for fungicide sensitivity and determine the susceptibility of the cultivars. In this context, as a result of surveys carried out in potato storages of Ödemiş and Torbalı counties in İzmir province in 2015–2016; Fusarium species obtained from diseased potato tubers were identified as Fusarium sambucinum, F.

The toxicants (fungicide and botanicals) showing maximum efficacy against the pathogen and minimum efficacy against milky mushroom (Calocybe indica) mycelia as per results of in vitro studies were further evaluated against T. harzianum under in vivo condition in mushroom house. Among fungicides only Bavistin (@150 ppm) and out of three botanicals only Nimbicidin (@4 per cent) were selected for management of the green mould disease in milky mushroom cultivation in bags.
