Guido Schnabel (Clemson University) just provided his recommendations for the remainder of the season concerning strawberry disease spray programs. See the strawberry IPM guide at www.smallfruits.org to supplement this information (especially FRAC groups), but I concur with his thoughts as we move forward this season. Guido writes. “In general, based…

As the coronavirus is wreaking havoc throughout the world, it is hard to get very excited about strawberry diseases – unless you make an income off strawberries. Unfortunately, the mild temperatures and almost continual rainfall are making it very difficult to manage strawberry diseases at this time. Based on diseases…

With all of the recent rain and plenty of green and ripe fruit we need to be on the lookout for diseases.
Row covers can be used to accomplish a few different things in strawberry plasticulture. For us in Georgia, they are best suited for protecting blooms and small fruit from frost as we near our first harvest dates.

Spring is just around the corner so we need to be thinking about our strawberry fertility programs. Now is a great time to get a tissue sample. This will give you a baseline and let you know if your pre-plant fertilizer has run out. It also allows you to check…

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…

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…
