    Developing a “Stress Breathalyzer” for Peanuts

    Yu-Chien Tseng, Brendan Zurweller and Diane Rowland, UF/IFAS Agronomy Department

    Growers typically use indirect methods to sense crop stress, such as soil moisture sensors to predict crop drought stress or models to predict disease risk. Directly monitoring the stress levels experienced by the crop would give an immediate snapshot of crop condition, …

    Highlights & Presentations from the 2018 Panhandle Row Crop Short Course

    This year’s Panhandle Row Crop Short Course took place on Thursday, March 1, 2018.  Extension Specialists from Florida, Georgia, and Alabama spoke to attendees providing production recommendations and various management tips for row crops farmers. Continuing education units (CEUs) were offered at the event for those with a restricted use pesticide license (Florida, Georgia and Alabama), as …

    Fungicide Options for Peanut Producers due to the Expected Chlorothalonil Shortage in 2018

    Nicholas Dufault, UF/IFAS Crop Pathologist, and Patrick Troy, UF/IFAS Row Crop Regional Agent

    As the 2018 peanut production season approaches, it is time for producers to start considering their fungicide programs. Chlorothalonil has been a staple fungicide in many peanut management programs, but shortages of this product are expected in 2018 as …

    Early-Season Considerations for Peanut & Cotton Production

    It’s only February, but it will be April before you know it. That means it is time to start planning for peanut and cotton planting season.

    Variety selection Peanut

    If you’re a peanut grower, you’re placing your orders for GA-06G now. Which is great – it’s a cultivar that sets a high bar for disease …

    More Nematicide Options for Florida Cotton and Peanut Growers in 2018

    Zane Grabau, UF/IFAS Nematologist, and Ethan Carter, Regional Crop IPM Agent

    Nematicide application, along with crop rotation and use of resistant cultivars, is a key tool for nematode management.  To that end, the number of nematicides/insecticides available to Florida cotton and peanut growers will be increasing in 2018, as a few products are …

    The Search for the Bigger than Life Peanut Variety Continues

    After attending the annual meeting of the National Association of Plant Breeders in Davis, California last summer, I took a couple of days to drive down to Sequoia National Park to see the Giant Sequoia trees.  As I walked through the forest, these trees were so large they seemed out of place among the pine …

    Insecticide Applications Can Inadvertently Cause Citrus Mite Outbreaks

    Xavier Martini, Pete Andersen, UF/IFAS North Florida Research and Education Center

    In May 2017, Asian citrus psyllids (Diaphorina citri) were found in the experimental citrus grove at the Suwannee Valley Extension Center in Live Oak.  The trees were quickly treated with an insecticide containing the active ingredient, cyantraniliprole. This treatment was highly justified as …

    Crop Nematode Damage a Serious Issue this Season

    After back to back mild winters, the 2017 growing season has been a banner year for pests. Prolonged cold weather normally diminishes pest populations, but this year pests of all types survived winter with populations that have increased dramatically.

    Most of the growing season, whiteflies were the major concern across fruit, vegetable and agronomic crops. …

    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 …

    Peanut Nodule Analysis to Assess Crop Health

    David Hensley and Diane Rowland, UF/IFAS Agronomy Department

    One of the primary benefits of growing legumes like peanut is their ability to convert nitrogen in the atmosphere to a form that is available for use throughout the plant. They do this by forming a symbiosis (a mutual “partnership”) with bacteria known as Rhizobia. …
