The incidence of hop powdery mildew on leaves, caused by Podosphaera macularis, collected from 1,606 transects in 77 commercial hop yards in Oregon and Washington over 9 years was used to assess variability in heterogeneity of disease and the estimated binary power law parameters. Spatial analyses of data sets were conducted at the level of individual rows (row level) and multiple rows within a...

The practices of conventional methods for maintenance management in Malaysian Polytechnic faced many issues due to poor service delivery, inadequate finance, poor maintenance plan and maintenance backlogs. The purpose of this study is to improve the conventional method practices which tend to be ineffective in Malaysian Polytechnic. The case studies were conducted with eight Polytechnics from f...

Abstract Key message Comprehensive management of urban greenery is a key approach to control fungal diseases trees and shrubs avoid the deterioration in their health status. Preliminary investigations on status related growing four green squares Warsaw were conducted 2017–2019. The examined plants affected by that are commonly identified greenery, e.g., powdery mildew (causal agents: Sawadaea t...

Project Number: 13C-3361-4795 TITLE: Epidemiology and control of apple powdery mildew Principal Investigator: G. G. Grove, Plant Pathology, WSU-IAREC, Prosser, WA Objectives • Develop a forecasting model to improve management of apple powdery mildew, caused by Podosphaera leucotricha. • Develop biorational disease and fungicide-resistance management programs • Lower disease pressure through cha...

Epiphytic yeasts, which colonize plant surfaces, may possess activity that can be harnessed to help plants defend themselves against various pathogens. Due to their unique characteristics, epiphytic yeasts belonging to the genus Pseudozyma hold great potential for use as biocontrol agents. We identified a unique, biologically active isolate of the epiphytic yeast Pseudozyma aphidis that is capa...

The ability of a parasite strain to establish and grow on its host may be drastically altered by simultaneous infection by other parasite strains, and dynamics under multiple infection have been suggested to be a major force driving pathogen evolution. Here, I studied whether hosts' induced defenses mediate dynamics of multiple infection of the fungal pathogen, Podosphaera plantaginis, infectin...
