Ten fungicides were initially tested on spore germination and mycelium growth assays, and five were selected for fruit protection assays; the data from these experiments are presented as general treatment means in Tab. Citado por Bompeix et al. Morphology of colonies and conidia Most of the isolates coming from citrus crops formed grey and salmon cottony colonies.

Controlling Colletotrichum is still a deficient task, as is our knowledge about the basic aspects of its biology such as the infectious agent and its genetic variability, inoculum dispersal and host specificity one single Colletotrichum species has been found causing crossed infection on several hosts. Thus, the pathogens can be said to be host specific, which is confirmed by studies on the genetic diversity of the same collection analyzed in this work Osorio et al.


Finally, the crossed infection tests gave negative results, as no symptoms of the disease were detected in organs inoculated with isolates taken from other crops Tab. A 20 g sample was fully homogenized in mL of distilled water and filtered through cheesecloth before use.
