Almond canker diseases are destructive and can reduce the yield as well lifespan of almond orchards. These may affect trunk branches both young mature trees result in tree death soon after orchard establishment severe cases. Between 2015 2018, 70 orchards were visited throughout Central Valley California upon requests from farm advisors for disease diagnosis. Two major identified, including Bot...

Fungi were isolated in pure cultures from decaying giant sequoias Geneva (Switzerland). Isolates genetically identified by ITS rDNA sequencing. Young sequoia trees artificially infected with a culture of Botryosphaeria parva. Henle-Koch’s Postulates demonstrated that parva was pathogenic to Sequoiadendron giganteum. When analysing the microorganisms associated canker and dieback symptoms (Sequo...

Grapevine Trunk Diseases (GTDs) are a major challenge to the grape industry worldwide. GTDs responsible for considerable loss of quality, production, and vineyard longevity. Seventy-five percent Chilean vineyards estimated be affected by GTDs. complex diseases caused several fungi species, including members Botryosphaeriaceae family Phaeomoniella chlamydospora , considered some most important c...

Some pathogenic species of the Botryosphaeriaceae have a latent phase, colonizing woody tissues while perennial hosts show no apparent symptoms until conditions for disease development become favorable. Detection of these pathogens is often limited to the later pathogenic phase. The latent phase is poorly characterized, despite the need for non-destructive detection tools and effective quaranti...

Identification of fungi and the International Code of Nomenclature underpinning this process, rests strongly on the characterisation of morphological structures. Yet, the value of these characters to define species in many groups has become questionable or even superfluous. This has emerged as DNA-based techniques have increasingly revealed cryptic species and species complexes. This problem is...

Grapevine trunk diseases (GTDs) cause significant yield losses worldwide and limit the lifespan of vineyards. In last few years, using biological control agents (BCAs) for pruning wound protection has become a promising management strategy these pathologies. This study aimed to compare antifungal activities grapevine-native Trichoderma harzianum isolate high-potential Bacillus velezensis strain...
