Dr. Bob Kemerait, UGA Plant Pathologist, provides the following peanut fungicide options with the short supply of Bravo/cholothalonil: What to do??
A. Replace 1.5 pt/A chlorothalonil with 15 fl oz/A Elast.
B. Replace 1.5 pt/A chlorothalonil with 10 fl oz/A Topsin/thiophanate methyl, but ONLY one time!
C. Replace 1.5 pt/A chlorothanil with 7.0 fl oz/A Stratego (concern about resistance management…)
D. Replace 1.5 pt/A chlorothalonil with 3.5 fl oz/A Absolute (concern about resistance management…)
E. Replace 1.5 pt/A chlorothalonil with 5.5 fl oz/A Alto (better to mix 1.0 pt/A chlorothalonil with 5.5 fl oz/A Alto, or at least SOME chlorothalonil with the Alto!)
F. Replace 1.5 pt/A chlorothalonil with 5.5 fl oz/A Alto + 5 fl oz/A Topsin/thiophanate methyl.
G. Extend chlorothalonil with 1.0 pt/A chlorothalonil with 1.0 pt/A Kocide.
H. Extend chlorothalonil with 1.0 pt/A chlorothalonil with 5.0 fl oz/A Topsin/thiophanate methyl.
I. Extend chlorothalonil with 1.0 pt/A chlorothalonil with 2.0 fl oz/A propiconazole.
