Efikasnost mandipropamida za suzbijanje prouzrokovača plamenjače krompira u poljskim uslovima

The efficacy of mandipropamid (Revus 250 SC) in controlling Phytophthora infestans in potato was evaluated in field trials. The efficacies of Revus 250 SC in comparison with standard fungicides Quadris (azoxystrobin) were tested in several localities in Serbia (Kasarske Livade, Valjevska Kamenica and Opovo) in 2007 and 2008. Both of the tested fungicides exhibited high efficacy in controlling potato late blight. The differencies in the efficacy of Revus 250 SC (96.3- 99.2%) and Quadris (94.1-95.5%) were insignificant. Our experiments showed that the investigated fungicide was highly effective against P. infestans even under high disease pressure.Ispitivana je efikasnost mandipropamida (Revus 250 SC) za suzbijanje Phytophthora infestans u usevu krompira u poljskim uslovima. Efikasnost preparata Revus 250 SC ispitivana je na nekoliko lokaliteta u Srbiji (Kasarske Livade, Valjevska Kamenica i Opovo) tokom 2007. i 2008. godine. Kao standard poslužio je Quadris (azoksistrobin). Oba ispitivana fungicida su ispoljila visoku efikasnost u suzbijanju prouzrokovača plamenjače krompira. Između efikasnosti Revus 250 SC (96.3- 99.2%) i Quadris (94.1-95.5%) nije utvrđena statistički značajna razlika. Naši ogledi su pokazali da je ispitivani fungicid visokoefikasan u suzbijanju P. Infestans, čak i u uslovima jake zaraze
