Environmentally Safe Drugs In Leaf Protection Of Diplocarpon Rosae F.a. Wolf (anamorph Marssonina Rosae (lib.) Died.) Against The Black Maculation
Abstract
A.B. Marchenko
As a result of the study of the efficacy of using biopharmaceuticals against black maculation of leaves Roses found that effectiveness of investigated of biological products during the growing season of the genus Rosa L. is 56.4±16.3% in the range from 21.1 to 72.3%. Thus, the highest values of protective action against black maculation of leaves roses had: Tryhopsyn (Pseudomonas and Trichoderma 6×109 CFU/cm3) – 72.8%, Tryhodermin BT (a.s. Trichoderma viride, titer of 2×109 CFU/cm3)+Planryz BT (a.s. Ps. fluorescens 5×109 CFU/cm3) (1:1) and Tryhodermin BT (a.s. Trichoderma viride, titer of 2×109 CFU/cm3) + Haupsyn BT (a.s. Ps. aureofaciens 5×109 CFU/cm3) (1:1) to 72.3%, Planryz BT (a.s. Ps. fluorescens 5×109 CFU/cm3) – 65.3%. Biologicals is restrain the development of pathology caused by causative agent Diplocarpon rosae F.A. Wolf on a variety of different groups of the genus Rosa L., namely the indicator of damage index in the samples of the group of Hybrid tea roses Kardinal 85 Kordes, Germany (1985) was 18.2%, climbing New Dawn Somerset Rose Nursery, USA (1930) by 2.2%, floribunda Leonardo da Vinci Meilland (1993) by 6.2%, English Abraham Darby Austin, United Kingdom (1985) by 6.7% less than without processing.
