Gall rust disease incidence of Falcata (Paraserianthes falcataria (L.) Nielsen) in Falcata - Based agroforestry systems in Misamis Oriental, Philippines

Abstract

Falcata - based agroforestry systems in eastern part of Misamis Oriental is affected by gall rust disease caused by Uromycladium tepperianum (Sacc,) considered as one of the most destructive disease. The objectives of this study at Misamis Oriental, Northern Mindanao were to (i) determine the status of gall rust disease incidence in selected eastern municipalities and city of Northern Mindanao, and (ii) determine the factors and its relationship with gall rust disease. The sampling intensity was 10% or 1,000 m2 of one hectare at each site. Twenty temporary sample plots per municipalities and city were identified and assessed with a total of 140 plots. Each plot contained 15-70 trees for observation. Gall rust disease incidence per municipalities and city varies ranging from occasional to very common. Across site the incidence is considered common (25->50%). Elevation, spacing and age were associated with reduction or increase in gall rust disease incidence in these parts of Northern Mindanao.
