The present work exposed some issues about the practical importance of peaches for our country and the need for chemical treatments to control peach leaf curl. Prevent losses caused by harmful organisms can be achieved by integrating agro measures, plant hygiene, biotechnical, biological and, not least, of the chemical. Health peach trees, with direct implications on the quality and quantity of production, be permanently secured in order to prolong plant longevity and maintaining interrelations within agroecosystems. In this context, the testing of new preparations (Agran 70 WDG, Ventop 350 SC, Chorus 75 WG) with fungicidal activity against the fungus Taphrina deformans (Berk.) Tul. and other fungi was the primary object of further investigations. Statistical data show that the efficiency of processing biological fungicide Agran 70 WDG dose of 0.5 kg / ha was lower than standard, and the dose of 0.7 kg / ha in the standard. Statistical data show that the efficiency of processing biological fungicide Ventop 350 SC dose of 1,4 l / ha was lower than standard, and the dose of 1,0 l / ha in the standard.
