Fungus weather!

Rain every week is leading to many disease problems. Here is a chart that reviews some of the common diseases we've been seeing at the nursery recently. I have been removing specific fungicide recommendations from my articles, as availability of specific products has changed. In most cases fungicides aren't necessary, application is impractical, and oftentimes labeled products really don't work.
Good news: hot, dry weather stops the spread of most diseases. And one thing we can count on in the Sacramento Valley is that we will eventually get hot, dry weather!
