Endura: 2011 Sunflower Head Rot Research DiscussionKent McKay – BASF Tech Service RepJune 22nd, 2011Deadwood, SD

Endura® Fungicide

• Endura: Boscalid, unique mode of action• Fungicide group 7: carboxamides• Wide spectrum of labeled crops and the control of

various diseases on the label• Very effective in control of Sclerotinia / white mold in

a number of crops

Sunflower Head Rot Fungicide Research

• Morden, Manitoba; Khalid Rashid • NDSU Langdon, ND; Scott Halley• NDSU Carrington, ND; Blaine Schatz, Sam

Markell• Irrigated and inoculated for high disease pressure

Sunflower Head Rot Fungicide Research

• 2008 – 2010 University based fungicide research results indicated that Boscalid (Endura, Lance) was very consistent and very effective in controlling head rot in sunflower compared to other fungicides

Endura® Fungicide Update

• 2011 Canada: Minor use registration for Lance (Boscalid) in sunflowers as a preventive head rot treatment, one application per season

• Continue to conduct sunflower head rot studies with NDSU in 2011

• Sunflower on the Endura Master label, so all the residue work has been completed

• 2011 ND Endura aerial fungicide demonstration trials planned

2011 Endura Aerial Trials

• Large scale, 20 – 40 acre aerial Endura sunflower head rot trials

• Eight locations from NW Minnesota to north central, ND

• Application rate needs to be defined• Timing of application• The benefit of multiple applications• Confection sunflowers and oil sunflowers

2011 Endura Aerial Trials

• Head rot incidence will be measured by NDSU and BASF Tech Service

• Seed yield an quality (percent sclerotia) will also be measured

• Develop fungicide management guidelines for the use of Endura for head rot suppression in sunflower
