ACLI RACALE announces the congress “Resilienza: Xylella research talks to people”, to be held in Salento, in September 2019
Along with the loss of millions of olive trees across the Apulian region (Southern Italy), the introduction and relentless spread of Xylella fastidiosa caused a serious socio-cultural problem: mistrust in science and scientists involved in the research of the fastidious bacterium fomented by a consistent part of the civil society. Nowadays, a considerable number of […]
EUPHRESCO network releases the final report of the PROMODE Project on monitoring and detection of Xylella fastidiosa
