Abstract
The genus Juglans (Juglandaceae) consists of 20 tree species referred to as walnuts and it is sub-divided into four taxonomic sections. The section Trichycaryon in which buttermut is the only member. The fungus, Sirococcus clavaganti – juglandacearum is an important pathogen causing considerable losses in butternut plantations. The butternut trees with age groups were found susceptible to this disease. In the present paper, an attempt has been made to see the safer fungicides, ArmicarbTM 100 against the pathogen Sirococcus clavaganti – juglandacearum. The result exhibits that ArmicarbTM 100, 0.3 per cent was found best and inhibited completely the growth of Sirococcus as compared to other treatment in vitro.
