Biology and epidemiology of <i>Diaporthe amygdali</i>: understanding how environmental factors influence fungal growth, sporulation, infection and lesion development on almond.

ABSTRACT:

Introduction

Diaporthe amygdali is a major pathogen causing twig canker and shoot blight disease on almond crops. Knowledge about the influence of environmental factors on the biology and epidemiology of this pathogen has mainly been obtained on peach, but there is scarce information on almond. Thus, the main objective of this research was to better understand how environmental factors, such as temperature and wetness periods, determine the cycle of this disease on almond crops in Mediterranean conditions.

Methods

Several experiments were conducted to obtain information about mycelial growth, sporulation, plant infection and lesion development using almond isolates of D. amygdali.

Results

Our results showed that the temperature ranges for both α-conidia
