    Target Spot In Cotton: Fungicide Timing And Varietal Differences – Reports From Beltwide

    By Owen Taylor, Editor

    This is the fourth of four audio podcasts covering a special symposium on target spot in cotton. The session was part of the 2013 Beltwide Cotton Conference in January in San Antonio, Texas.

    In this segment, Austin Hagen – an Auburn University plant pathologist – presents research findings from a variety of trials looking at fungicide timing to prevent or control target spot in cotton and also findings about levels of varietal resistance to the disease.

    Additional comments toward the end of the audio were made by Bob Kemerait, University of Georgia plant pathologist who moderated the symposium.

    Here are links to the first three podcasts:

    • Lessons From Other Crops. An overview of target spot and its underlying pathogen. G.E. Vallad, a University of Florida plant pathologist, discusses the scope of crops target spot affects worldwide and how the pathogen works.
    • How Much Does Premature Leaf Loss Matter? Target spot leads to defoliation. At what point might that lead to yield and/or quality loss? Glen Ritchie, a plant physiologist with Texas Tech University, takes a look at research that helps quantify how much is too much.
    • How Do You Time Fungicides For Target Spot Control? And what kind of yield gain might be expected with fungicide sprays?  Jared Walls, a University of Georgia grad student in plant pathology, provided insight on that question, basing his presentation on research he and others have conducted.
