Signs and symptoms of white mold (southern
stem blight) in peanuts
DuPont™ Fontelis® fungicide
Active ingredient name: Penthiopyrad
Chemical class: FRAC Group 7, carboxamides
Formulation: 20 SC
DuPont™ Fontelis® fungicide: a proven track
record in peanuts
Since launching in 2012, Fontelis® has delivered excellent
control of key peanut diseases, such as white mold
(southern stem blight), leaf spots and rusts, and other soil
and foliar diseases.
Whether Fontelis® is used two or three times in a program,
results from 2007 to 2015 show that Fontelis® increased
yield over competitive programs by an average of
339 lbs/A.*
Two signs of this disease are white cottony growth (fungal mycelium)
and round, brown sclerotial bodies on the peanut stems and soil.
Symptoms are stem rot with wilt and death of affected foliage.
A recent Georgia on-farm, replicated, large-plot trial by
Bulloch County Extension resulted in timely white mold
control and yield results, demonstrating the enduring
activity of Fontelis® for this tough-to-control peanut disease.
*Competitive programs compared to Fontelis® two- or three-spray programs
(2007–2015) were under similar conditions. In place of Fontelis®,
competing programs used two or three applications of 18.2 fl oz/A
Abound, 13–16 fl oz/A Convoy + 1.5 pt/A Bravo Weather Stik, or 7 fl oz/A
Provost. Another competing program used straight chlorothalonil at
1.5 pt/A. Yield values: Fontelis® (n = 69), competing program (n = 86),
nontreated (n = 43).
Under certain conditions, white mold can move along the
underground plant parts and affect the nuts, causing direct losses.
