Recommendations for the control of coffee leaf rust on Arabica coffee in Papua New Guinea

Abstract

Coffee is the most important cash crop in Papua New Guinea. For most people in the highlands and the mountains of other provinces, coffee is the only real source of cash income. Coffee leaf rust disease was identified in the Baiyer River area of the Western High­lands Province on 30th April 1986. Since then it has been found in seven other provinces. They are the Enga, Simbu, Madang,. West Sepik, East Sepik, Eastern Highlands and Morobe Provinces. It is likely that the disease will eventually spread to all coffee growing provinces.
