Disease Modeling in Hop

Our plant pathology outreach efforts have focused on the development of value-added products for the hop industry. To develop our disease models, we work closely with the Washington State University Agricultural Weather Network (http://weather.wsu.edu). AgWeatherNet is a system of 136 weather stations distributed throughout Washington state but concentrated in the irrigated regions east of the Cascade Mountains. The weather data collected by these remote station are the raw materials that drive an extensive portfolio of crop, pest, and disease models.

Following are a series of "screen shots" from the hop disease forecasting models within AgWeatherNet.

AgWeatherNet PM regional summary

ABOVE: Regional summary of powdery mildew expected in hop on 8-29-11.

List of PM fungicides

ABOVE: A list of fungicides and related information.

Spray intervals

ABOVE: Growers can use charts like this to determine appropriate spray intervals based upon their own level of disease pressure.

Ag Alerts sign-on page

ABOVE: It's easy (and free) for growers and others to sign up for customized alerts.

Alert example

ABOVE: An example of a customized alert.
