Abstract
The control of the carrot Alternaria leaf blight diseases caused by Alternaria dauci (Kuhn.) Groves & Skolko is actual problem. This paper shows results of the chemical control of Alternaria dauci (Alternaria leaf blight) on the carrot and there are presented results of application with some new fungicides.
The examination is done in 2014 and 2015 year in village Stajkovci near Skopje, Republic of Macedonia. The most efficacious fungicide applied in this research were Score 250 EC (difenoconazole) with 81,45 % of efficacy, Sighnum (boscalid + pyraclostrobin) - 79,99%, Quadris (azoxystrobin) - 79,53% of efficacy of protection with Alternaria dauci in 2014. Fungicide Score 250 EC (difenoconazole) efficacy was 93,62% and Quadris (azoxystrobin) efficacy was 91,97% in 2015 year. Fungicide Dithane M-45 (mancozeb) application index of efficacy in 2014 was 68,38% and in 2015 it was 75,85%.
