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.
