摘要: ABSTRACT ( Eichhornia crassipes ) plants. In accordance with the results, theETD media yielded more mycelial growth than BD and V8media, especially after 144 h of agitation. However, V8 mediuminduced a higher pathogen sporulation rate, when cultivated forup to 120 h. The obtained inocula produced in ETD mediacaused values disease severity. dehydration periodof biomass from 72 was favorable for higherconidial production. period has no effect ondisease severity.Fitopatol. bras. 29(2), mar - abr 2004 189O aguape [ (Mart.)
