Two sessions on potato disease management were held at the 2013 Idaho Potato Conference in Pocatello, ID on January 24. See the attachment below for slides relating to some of the topics that were discussed in the sessions.
See how different fungicide regimes performed against early blight and white mold for disease control, yield, and economic return.
When Quadris was introduced for managing foliar diseases of potatoes in 1998, growers' ability to control early blight increased dramatically. Other strobilurin products have followed. Recently fungicide resistance has been observed for isolates of the early blight fungus. What does this mean for using strobilurin fungicides in the field?
Can late-season strobilurin fungicide applications protect sugarbeets from frost damage?
2012 was a relatively light year for pink rot in our research trials. However, we did see significant disease control with phosphorous acid (Resist 57).
If water becomes short, how much will sugarbeets suffer from reduced irrigation?
Many different tools are required to manage pink rot appropriately, including irrigation, fungicides, and post-harvest treatments. This presentation outlines some of our recent research in these areas.
Fumigation with metam sodium can be an effective way to manage nematodes and weeds in sugarbeets. This study was conducted to determine if relatively low rates of metam sodium (20 gallons/acre) applied to the top 2-3 inches of soil by chemigation could be effective in reducing weed populations.
You didn't make any fungicide applications to deal with pink rot. However, in late July or early August you find some pink rot in the field. Is it too late? Can you still apply fungicides and get some level of disease control?
There are a lot of fungicides available for managing late blight. One of the attached articles discusses what to use and how to use it. The other lists steps growers can take approaching harvest and going into storage.
