1. Endura: 2011 Sunflower Head Rot Research Discussion Kent McKay – BASF Tech Service Rep June 22 nd, 2011 Deadwood, SD

2. 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

3. 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

4. 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

5. 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

6. 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

7. 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
