Spraying to Suppress Coffee Leaf Rust (Hemileia vastatrix) in Hawaii

Andrea Kawabata and Stuart T Nakamoto ( June, 2021 )

Summary

Over a three- to five-month period, one CLR lesion can produce upwards of 400,000 spores that become airborne and easily spread throughout a farm and between farms. If left untreated, berry production and foliage losses caused by CLR on non-resistant coffee varieties can be significant, ranging between 30% and 80%. Yield is completely lost when the tree is killed. Spraying with the proper rotation, rate, and frequency of CLR-approved fungicide products is important for management. Monitoring, detecting, and spraying CLR at an incidence of 5% or less in addition to implementing other cultural practices, helps to make spraying more effective.
