    Why is Nematode Damage Patchy in Crop Fields? How Does this Affect Management Decisions?

    I’ve had the opportunity to visit a number of grower fields this summer to assess potential nematode damage and I’ve often been asked this question: “Why is nematode damage worse in one section of a field than another, or worse in one field than another one nearby? ” This question reflects the fact that nematode …

    Scout Soybeans for Kudzu Bugs and Redbanded Stink Bugs

    After a mild winter, with relatively few nights below freezing, it should be no surprise that insect populations are spiking early. One example of this is armyworms, which began showing up in early-mid June across areas of Jackson County, a pest typically found later in July.  In early June, soybean pests have begun to appear …

    The How and Why of Preemergence Herbicide Incorporation for Row Crops

    Preemergence herbicides are a powerful way to prevent weed infestations before they start.  In our current climate of glyphosate and ALS-resistant weeds, a good preemergence program is more valuable than ever.  However, method and timing of application dramatically impact the efficacy of many preemergence herbicides.  To improve their reliability, preemergence herbicides should be incorporated – …

    Field Crop Nematode Management Publications Updated

    One of my goals since starting as field crop nematologist at the University of Florida last June was to update the nematode management guides for Florida field crops, so that extension agents and growers have access to active copies of these documents.  I’m happy to announce that guides for field corn, soybeans, and cotton have …

    Determining Optimal Plant Populations for Your Variable Rate Planter

    You’ve spent good money on precision ag, GPS guided equipment.  Your rows are planted straight, your pesticide sprays are very precise, and you have improved harvest efficiency.  You’re set up for variable rate planting and you have a yield monitor, but aren’t quite sure what else to do with them?  Here are some ideas to …

    Fungus Keeping Kudzu Bugs below Thresholds on Soybeans

    Kudzu bugs are a fairly new pest for our area but are already familiar to residents in Northwest Florida.  Researchers are continuously studying new pests to make research-based control recommendations.

    One research project (UGA research article) is investigating a fungus, Beauveria bassiana, that infects kudzu bugs.  Beauveria bassiana causes white muscadine disease which is fatal for many insects.  Beauveria bassiana affects kudzu …

    Soybean Rust Confirmed in Quincy Soybeans

    Soybean rust appeared early this year.  The mild, wet winter has resulted in a higher incidence and severity of soybean rust found on kudzu than in recent years.  Soybean rust was confirmed in early planted soybean sentinel plots on June 2, at University of Florida, Quincy, NFREC.  This is very early for discovery of the …

    Resistance of Tobacco Thrips to Neonicotinoid Seed Treatments

    Danielle Sprague and Joe Funderburk, North Florida REC, University of Florida, IFAS

    Tobacco thrips, Frankliniella fusca, are seedling pests of peanut, soybean, and cotton throughout the southern USA. The adults and larvae feed on the developing leaves, causing injury during the very early vegetative stages of these crops. Severe injury to …

    UGA Decision Aids can Help Farmers Decide What Crops to Plant in 2016

    2015 was a very challenging year for Panhandle row crop farmers with the double whammy of low commodity prices and unfavorable weather.  As a result, many farmers are uncertain as to what crops to plant for the coming year.

    The University of Georgia has a nice tool or decision aid that provides estimated returns on …
