In Vitro and In Vivo Effect of Poplar Bud Extracts on Phytophthora infestans: A New Effective Biological Method in Potato Late Blight Control.

摘要: The effect of populin extract from black poplar (Populus nigra) on seven different late blight strains was tested under laboratory and field conditions. growth rate hyphae found to be significantly lower in vitro after 3 4 v/v% applications. Stain M16 resistant treatment lab conditions, however. Both 5% 10% concentration reduced the strain's severity potato leaves conditions proved even more effective than conventionally used fungicides Infinito 687 Sc Valis M. Higher infection intensity at 1% level observed 24 h using M, same trend toward remained 48 72 as well. Low, almost-no-infection detected an open condition. Altogether, it can concluded that a low-cost option for growers environmentally friendly approach control.
