Microdochium Patch Fungicide Control Strategies

August 15, 2010

Avoiding Buildup of Resistant Fungi

Most failures are probably not due to fungal resistance to fungicides.
Fungal resistance is most likely to develop where you over use systemic fungicides and don’t alternate modes of action.

Examples in the PNW on Microdochium Patch: Clearys 3336, Chipco 26GT, and Heritage.
Pathologists have numerous theories on the best strategies for managing fungicides to avoid resistance.

Annual Bluegrass , Poa annua L.

February 1, 2008

Revised Feb. 2008

In nature, annual bluegrass, Poa annua L. behaves as a true annual. It germinates in fall or spring when moisture is adequate and develops quickly, often flowering six to eight weeks after germination. In the Pacific Northwest we see it most commonly as a winter annual (Fig 1). After flowering and setting seed these annual types die typically from drought and leave dormant viable seed behind to germinate when moisture again becomes available. This efficiency in seed production makes annual bluegrass a major component of the seed bank of cultivated soils.
