Alexandrov, V. (Complex Experimental Station, Yambol (Bulgaria))
Under laboratory conditions the effect of some fungicides upon the charcoal rot's causes was tested.The fungicides metil-topsin 70NP supperess the growth of the pathogen's mycelium,but the preparation rolnilan 50NPdoesn't influence it. The fungicides ,which showed a suppresing effect upon the pathogen in vitro were comparatively tested in the period 1995-1996 under field conditions.The tested preparations showes low effectiveness (from 7,3% to 14,9%) upon the size of attack by the disease and that's why they cann't be applied in order to control it.
