Efficacy of fungicides and organic formulations against wet bubble disease of white button mushroom

摘要

The studies were conducted to evaluate different fungicides and organic formulations for the management of wet bubble disease of white button mushroom caused by Mycogone perniciosa. In vitro evaluation of fungicides was carried out to access the efficacy of Ave fungicides singly as well as in combinations against mycelial growth. Among the fungicides, propiconazole and trifloxystrobin 25 + tebuconazole 50 at 20 ppm were most effective as both of them provided 100 mycelial inhibition as compared tocontrol. Among the five organic formulations, Himsol and Jeevamrit at 50 cone, were most effective followed by Panchgavya and Jeevamrit and Tamarlassi against Mycogone perniciosa. Under in vivo conditions the fungicide trifloxystrobin 25 + tebuconazole 50 (Nativo) gave 87.5 disease control followed by 86.2 in carbendazim 12 + mancozeb 63 (Saaf) and among the organic formulations maximum disease control was observed in Himsol (87.9) followed by Panchgavya (85.8) and Jeevamrit (81.3). Tamarlassi was found least effective for disease management.
