Assessment of disease attack on eucalypt species and provenances in trial plantings in Eastern South Viet Nam<\/strong><\/p>\n

Summary:<\/em><\/strong>The diseases of eucalupts appeared in late 1980s in the Eastern South Viet Namand in the 1990s they have spread to other regions. Disease attack is classified in 5 levels: No disease attack, low level attack, average attack, serious and very serious attack in the trial plantings established in Song May (Dong Nai), Bau Bang (Binh Duong) and Tan Tao (Ho Chi Minh city).<\/p>\n

From results of the assessment and trials with different eucalypt species conclusion is made by the author on main pathogens of the eucalypt folioge together with recommendations on selection of eucalypt species for forest planting programmes and for high productivity objective.<\/p>\n
