Postbloom fruit drop is an important citrus disease caused by Colletotrichum acutatum. Severe outbreaks can develop when rainy periods occur during citrus bloom. Under these conditions, explosive epidemics are observed despite relatively short inoculum dispersal distances typical of this pathogen. C. acutatum can survive on citrus leaf surfaces after formation of appressoria, but survival on weeds has not been characterized. The survival of C. acutatum on seven species of weeds was evaluated… CONTINUE READING
