Effect of static magnetic field on growth and sporulation of some plant pathogenic fungi

Growth and sporulation of phytopathogenic microscopic fungi were studied under a static magnetic field. The applied flux densities were 0.1, 0.5, and 1 mT. The magnetic field decreased the growth of colonies by 10% using this flux density region. At 0.1 mT flux density, the deviations are significant, P  = .001, while in other cases the deviations generally are not significant. At the same time, the number of the developed conidia of Alternaria alternata and Curvularia inaequalis increased by 68–133%, but the number of Fusarium oxysporum conidia decreased by 79–83%. The deviations are generally significant at the P  = .05 level. Bioelectromagnetics 25:316–318, 2004. © 2004 Wiley‐Liss, Inc.
