Field Efficacy of Mandipropamid for the Control of Potato Late Blight

Abstract

The efficacy of mandipropamid (Revus 250 SC) in controlling Phytophthora infestansin potato was evaluated in field trials. The efficacies of Revus 250 SC in comparison withstandard fungicides Quadris (azoxystrobin) were tested in several localities in Serbia(Kasarske Livade, Valjevska Kamenica and Opovo) in 2007 and 2008. Both of the tested fungicidesexhibited high efficacy in controlling potato late blight. The differencies in the efficacyof Revus 250 SC (96.3- 99.2%) and Quadris (94.1-95.5%) were insignificant. Our experimentsshowed that the investigated fungicide was highly effective against P. infestans evenunder high disease pressure.
