    Be Proactive to Ward Off Armillaria Root Rot

    Recently, an Extension Agent in the Florida Panhandle received a picture of some mushrooms popping up in a client’s garden.  These particular mushrooms were in a spot where leftover mushroom compost had been dumped.  The compost was previously used to grow oyster mushrooms and the client was hopeful that she had more oyster mushrooms growing in her …

    Fig Leaves Dropping Early?

    Hopefully, by this time of year, most north Florida gardeners have harvested their figs and are enjoying fig preserves or fig bars. But if you’ve noticed your fig leaves dropping a little early, it may be a sign of the fungal disease Fig Rust (Cerotelium fici). Figs are a great fruit tree for the north …

    Recent Weather Fueling Fungi

    Florida’s panhandle has received quite a bit of rain this summer. In the last three months, depending on the location, approximately 15 to 35 inches of rain have come down, with the western panhandle on the higher end of that range. In addition to the rain, we all know how hot it has been with …

    Citrus Canker in Northwest Florida

    In November 2013, citrus canker was found for the first time in the Florida panhandle in Gulf Breeze in southern Santa Rosa County. The Florida Department of Agriculture and Consumer Services (FDACS) tested and confirmed the disease on grapefruit trees in a residential landscape. Since that time, citrus canker has been confirmed on citrus trees …

    Get Those Fairies Off My Lawn!

Occurrence …

A microscopic bacterium named Candidatus Liberibacter asiaticus, the cause of Citrus Greening (HLB), has devastated the citrus industry worldwide. This tiny creature lives and multiplies within the phloem tissue …

    Fall Turf Issues

    The crisp air of fall is upon us. Maybe. We live in northwest Florida and we are not experiencing the change in weather just yet. With the change in weather coming, we are having specific issues in turfgrass lawns and are sure to have others in the near future. Extension agents in the western panhandle have …
