Grape.jpgEditor’s Pick
Recent findings on grapevine yellows, caused by phytoplasmas on grapevines worldwide, suggest that the epidemiology and adaption to ecological conditions are evolving. Tessitori and colleagues report on these findings in an updated minireview, “Flavescence Dorée and Bois Noir Diseases of Grapevine Are Evolving Pathosystems.” View articlePamela D. Roberts, Editor-in-Chief, PHP
 
Apple.jpgMost Popular PHP Article
Apple growers require management practices that produce high-quality fruit yet minimize the number of chemicals used for adequate disease control and horticultural practices. Certain chemicals applied for bloom thinning also have fungicidal properties and may provide protection against early season diseases. View article.

HLB.jpgHuanglongbing on U.S. Citrus
Huanglongbing (HLB) is a devastating disease that affects citrus worldwide. In the open access Phytobiomes article “Bacterial and Fungal Next Generation Sequencing Datasets and Metadata from Citrus Infected with ‘Candidatus Liberibacter asiaticus,’” Ginnan et al. provide amplicon-based next-generation sequencing (NGS) datasets of the bacterial and fungal taxa associated with budwood, leaves, and roots from the same citrus trees from five orchards in different regions of Florida.
 
The importance of early detection and risk assessment of HLB are addressed in the PMN webcast “Risk-Based Residential HLB/ACP Survey for California, Texas, and Arizona,” by Tim R. Gottwald, USDA–ARS. View webcast.
