Distribution and Characterization of Podosphaera macularis Virulent on Hop Cultivars Possessing R6-Based Resistance to Powdery Mildew

Creator:

Wolfenbarger, Sierra N., Massie, Stephen T., Ocamb, Cynthia, Eck, Emily B., Grove, Gary G., Nelson, Mark E., Probst, Claudia, Twomey, Megan C., and Gent, David H.

Abstract:

Host resistance, both quantitative and qualitative, is the preferred long-term approach for disease management in many pathosystems, including powdery mildew of hop (Podosphaera macularis). In 2012, an epidemic of powdery mildew occurred in Washington and Idaho on previously resistant cultivars whose resistance was putatively based on the gene designated R6....

Pre- and Postinfection Activity of Fungicides in Control of Hop Downy Mildew

Creator:

Gent, David H., Twomey, Megan C., Wolfenbarger, Sierra N., and Woods, Joanna L.

Abstract:

Optimum timing and use of fungicides for disease control are improved by an understanding of the characteristics of fungicide physical mode of action. Greenhouse and field experiments were conducted to quantify and model the duration of pre- and postinfection activity of fungicides most commonly used for control of hop downy...

Meta-Analysis Reveals a Critical Period for Management of Powdery Mildew on Hop Cones

Creator:

Nelson, Mark E., Gent, David H., and Grove, Gary G.

Abstract:

Results of 28 field trials conducted over a 12-year period investigating management of hop powdery mildew caused by Podosphaera macularis were quantitatively summarized by meta-analysis to compare product efficacy and use patterns by mode of action as defined by Fungicide Resistance Action Committee (FRAC) groups. Availability of original observations enabled...
