Fungicide Selection Peanut Notes No. 167 2019

Question to Dr. Shew:

Is the attached fungicide material still effective for leafspot or white mold? [Propi-Star® EC]

Answer:

This is propiconazole, the same a.i. as in Tilt. Propiconazole still is registered in the US but as far as I know shellers will not accept peanuts that have been sprayed with it. As with Tilt, the best use is a tank mix with Bravo for leaf spot control. It has very little activity against stem rot.
