INTRODUCTION 1. Rationale Developing mono species plantation with large scale acacia plantation in Vietnam have been meeting high risk of disease especially wilt disease caused by Ceratocytis sp and pink disease caused by Corticium samonicolor leading to seriously reducing wood productivity of plantation. Another thing has been receiving attention from experts some acacia species may become invading grasses competing with indigenous species requiring further work
