“The Kona Coffee Farmers Association is focused on assisting farmers in learning how to manage this new threat to our livelihood. By coordinating with local, state, national and international groups, KCFA seeks to provide accurate information to our membership, so that farmers can take this as foundation and use it to learn with neighbors about best steps to take. That way we can all work together to deal with this pest, which moves fast and which no one has managed before in Hawaii. As a group and as a team of fellow coffee farmers, KCFA members can work together on best management strategies to continue forth successfully.” –Colehour Bondera, KCFA President
