Participatory survey of citrus in the “Recôncavo Baiano region” with emphasis on the threat of huanglongbing

Abstract

Huanglongbing (HLB) is one of the most devastating diseases for citrus sector. In Brazil, the state of Bahia is free of the disease, however it is on constant alert to prevent its introduction. One of the main areas of citrus exploitation in the state is located in the Recôncavo Baiano’s identity territory and is characterized by family-based production. This study aimed to perform a participative phytosanitary diagnosis with citrus growers from the “Recôncavo Baiano” region, recording their perception regarding the HLB and its vector, Diaphorina citri. The diagnosis, which featured 109 interviews, was carried out in five prominent cities in citrus production (Cruz das Almas, Governador Mangabeira, Muritiba, Santo Antônio de Jesus and São Felipe). The results showed that 70% of citrus growers never heard of the disease. It also indicated that only 6% of farmers have technical assistance. Even with the tradition of citrus farmers, the use of technologies is still limited. The presented results constitute an important tool for phytosanitary defense, as it provides strategic information that enable the planning of indispensable actions for preventing HLB entry in this territory, and also to minimize its negative impacts, contributing with the maintenance of the citrus production chain.

“…Part of the grower surveys referred to monitoring practices, with most respondents favouring scouting for the psyllid and surveys, but not making use of early detection methods that could precede the statutory qPCR tests. Participatory citrus grower surveys of HLB aimed at diagnosis have also taken place in Bahia, Brazil, where D. citri is present but the disease is currently absent and phytosanitary preparedness is considered possible only through grower participation (Oliveira et al 2021).…”
