| description | Development of pink disease on the various ages of Acacia crassicarpa Cunn Ex. Benth.. The increase in the value of pulp
and paper exports in Indonesia is partly due to the development of industrial forest plantations of acacia on peatlands. Acacia
crassicarpa grows well on peatlands with high productivity. However, the development of pink disease is a threat to the
growth of A. crassicarpa, both in the nursery and in the field. This study aimed at examining the development of pink disease
on the various ages of A. crassicarpa. The study was conducted using census method on plants at aged 4, 24 and 42 months.
Variables observed were symptoms, incidence, and severity of disease. Data were analyzed descriptively and regressively to
understand the relationship between the incidence and severity of the disease and the age of the plant. The results showed
that the symptoms that appearing at the seedling level were similar to those the sapling, poles and tree level. The presence of
thin colonies of cobweb-like (cobweb stage), mycelia aggregation from the cobweb stage (pseudonodular stage), and the
appearance of pustules and pink incrustation (teleomorph stage) were common symptom. However, disease incidence and
severity were moderate at the seedling and mild at the saplings, poles and trees level. The incidence and severity of disease
decreased with increasing age. |
