    Planting Date is Critical for Fusarium Wilt Management in Watermelons

    Fusarium wilt is caused by the soil borne fungus Fusarium oxysporum, which continues to be a problem for many Florida watermelon producers. Management of this devastating disease requires an integrated approach that combines conventional and novel techniques. Site selection is a critical step in any watermelon disease management program, and understanding the disease history …

    Battling Scab in Panhandle Pecan Trees

    Pecans are grown throughout the Panhandle of Florida. The western side of the Panhandle tends to be acreage dedicated to home gardeners, while the eastern counties have more commercial acreage.

    Protecting Fall Vegetable Crops after the Hurricane

    As if the fall season wasn’t challenging enough from a pest and disease perspective, throw in a hurricane and it gets much worse. Luckily, the storm missed most of the Panhandle. Tomato and cucurbit producing areas in Gadsden and Jackson counties likely saw the greatest impacts from Hurricane Irma. The biggest problem was the wind …

    On the Lookout for Peanut Diseases

    The rainy June and July have been both a blessing and a curse.  A blessing because the crops have not suffered for lack of water and a curse for peanut because wet fields prevented or delayed fungicide application and because it provides ideal conditions for fungal diseases to develop.

    This is especially true for leaf …

    Potassium Deficiency in Hay Fields can Enhance Disease Issues

    The Yellow Bahiagrass Hayfield

    At the end of June, a Jackson County rancher noticed something strange about his hay field.  The field was gradually turning yellow and was not growing well.  Typically plants turn yellow as the result of a nitrogen deficiency, but this field had been fertilized for hay production.  Upon inspection, the leaves …
