Anthracnose fruit rot disease, caused by fungal Colletotrichum species, is one of the most significant disease problems of commercial strawberry production in Georgia and the Southeast. Resistance to site specific fungicides could result in control failures if proper resistance management strategies are not used.

Please see the link below for information concerning the current status of QoI fungicide resistance in Georgia. This is important information for your 2020 disease control program. Colletotrichum resistance to QoI fungicides such as Abound and Pristine are prevalent throughout Georgia

Scouting for Two-Spotted Spider Mites is critical early in the strawberry season. Managing this pest along with diseases will help plants be more productive once we move to spring harvest season.

Anthracnose is prevalent in strawberry plantings at this time. As mentioned in the last post, I am concerned about resistance. If you identify anthracnose in your planting, have it tested for resistance to the QoI (strobilurin) chemistry class (Abound, etc.). While you wait for test results, apply Switch + Captan at high rates for the…

We are observing significant anthracnose epidemics in Georgia strawberries at this time. Unfortunately, we have determined that the anthracnose fungus has developed resistance to the strobilurin (quinone outside inhibitor; FRAC 11) class of fungicides (e.g. Abound, Pristine). This is resulting in extensive disease, as spraying these materials provides no or limited control of the disease…

Because of the warm February temperatures our strawberry crop was advancing fast. That is why most of it is under covers as I type this post.

I know the groundhog said that we will have an early spring but we still have frost and freezes in a normal Georgia spring. Go ahead and get the row covers ready because it looks like we may have a roller coaster ride ahead of us. In middle Georgia we normally begin our fertilization program…

We are already having Botrytis showing up on strawberry blooms. It is therefore a good time to test Botrytis for resistance to the various fungicide classes that are active against this pathogen group. Clemson University (Guido Schnabel) will once more test for resistance to Botrytis, but this will be the last year the service will…
