Chlorothalonil Short, What do we do?

Posted by romeethredge on May 28, 2015

 Peanuts and the short supply of Bravo/cholothalonil:  What to do?? Here’s what Dr. Bob Kemerait, UGA Plant Pathologist says will be good. 

 

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.
