<em>In vitro</em> evaluation of fungicides against growth of <em>Fusarium oxysporum </em>f. sp. <em>cubense </em>causing panama wilt disease of Banana

Abstract

The banana crop suffers from a number of devastating diseases caused by fungi, bacteria, viruses, nematodes, and a number of environmental factors. The major losses of banana at present by Panama wilt disease pathogen of banana and its management is very typical because it is caused by a soil-borne pathogen (Fusarium oxysporum f. sp. cubense). An experiment of fungicides was conducted in the laboratory of plant pathology BAU, Sabour for In-vitro evaluation of the fungicides viz. carbendazim, azoxystrobin and propiconazole against Fusarium oxysporum f. sp. cubense causing Panama wilt disease of banana. The results of the experiment revealed that among the fungicides used, carbendazim @ 500 and 750 ppm completely inhibited the mycelial growth of Foc followed by azoxystrobin (32.96, 11.30, 8.12 and 7.16 mm at 100, 250, 500 and 750 ppm respectively). The incorporation of carbendazim at higher concentrations viz., 500 and 750 ppm is very effective for the management of Panama wilt disease of banana.
