late blight in potatoesCourtesy Agricultural Research ServiceLate blight is one of many fungal diseases that plague potatoes.Like many tools, fungicides are most beneficial if used correctly.

To help potato growers get the most from those tools, Focus on Potato has released a new Web seminar, "Chemical Control of Foliar Plant Diseases in Potato: Application of Fungicides."

The 49-minute program is hosted by Phil Hamm, an Oregon State University plant pathology professor based in Hermiston.

In it, Hamm will discuss:

• Fungicide penetration into the canopy following various application methods,
• How much of the material applied remains at the canopy level nearly a week later,
• What are the results of repeated applications related to fungicide amount through time,
• Why timing of application is important to get the best disease control possible and
• The impact of increasing or decreasing water amounts in the application.

The presentation will be available through Dec. 31.

Focus on Potato is produced by the Plant Management Network, a non-profit collaboration among the American Phytopathological Society, American Society of Agronomy and Crop Science Society of America.
