Horticulture is tremendous industry and has role in daily life in Tonga. Many people are involved in agriculture and of those the majority are involved in subsistence and semi-subsistence agricultural activities with only 5% engaged in commercial activities (Tongan Agriculture Sector Plan).

In our project we run clinics to help growers identify their pest and disease issues and help them develop plans to manage the pests and diseases. We ran the plant health clinic at every district of the main island and three main outer islands. The farmers come to the clinic with their own sample of pest and disease and we try to identify it.
