Damage periods of the main diseases occurring in vineyards during the annual development phases

Abstract

In the study, the researchers focused on understanding the developmental stages and damage periods of several key pathogens affecting vineyards. Gloeosporium ampelophagum Sacc, Uncinula necator Burrill, Agrobacterium tumefaciens Conn, Plasmopara viticola Berl & De Toni, Cercospora vitis Sacc, and Botrytis cinerea Persoon are known to significantly impact vine health and grape yield. By analyzing the optimal periods of development for these pathogens, the researchers aimed to provide vineyard managers with valuable insights for implementing effective disease management strategies. Vineyard diseases pose a significant threat to grape production worldwide, affecting not only crop yield but also the quality of the final product. Gloeosporium ampelophagum, for example, causes anthracnose, leading to fruit rot and leaf lesions. Uncinula necator, the causal agent of powdery mildew, can reduce grape quality and yield if not controlled. Agrobacterium tumefaciens causes crown gall disease, affecting the vascular system of the vine and ultimately leading to reduced vigor and yield. Plasmopara viticola, responsible for downy mildew, can cause severe defoliation and reduce fruit quality. Understanding the developmental stages and damage periods of these pathogens is crucial for implementing timely and effective control measures. Integrated disease management strategies that combine cultural practices, biological controls, and chemical interventions can help mitigate the impact of these diseases. By identifying the optimal periods for disease development, vineyard managers can tailor their management practices to minimize the impact of these pathogens on vine health and grape production.
