EFFECT OF TEMPERATURE AND pH ON FUSARIUM OXYSPORUM F. SF.PSIDII CAUSING WILT DISEASE IN GUAVA

摘要

Among the major production constraints in guava (Psidium guajava L.), wilt caused by Fusarium oxysporum F. sp. Psidii is very serious. The growth and sporulation of the fungus varied significantly at different temperatures and pH values. Maximum growth and sporulation was recorded at 25 deg C as compared to 30,20 and 10 deg C. However, maximum growtli and sporulation of the fungus was recorded at pH 7.0.
