Abstract

Pink fungus in Java is classified as Upasia salmonicolor (Basidiomycetes: Corticiaceae) and its anamorph is Necator decretus. This fungus is a serious pathogen which attacks many woody plants. The pink fungus in Java exhibits five developmental stages on the surface of the host bark: I. An initial cobweb stage as thin, white, cobweb-like hyphal layer, which creeps over the surface of the bark, during which penetration of the host occurs; II. Pseudonodular stage, as conical white pustules occurring only on lenticels or cracks, and only on shady side of branches; III. Teleomorph, occurs as pink incrustation and pink pustules on shady side of branches; IV. Nodular stages, as globose white pustules occurring chiefly on intact bark, but also on the lenticels or cracks, on exposed side of branches; V. Anamorph, as small orange-red sporodochium, on exposed side of branches.

Abstract

The result of this study showed that most of fungus as thin mycelial layer on the coffee leaves were connected with pink fungus on the branch. The microscopic study showed the hyaline mycelia producing perpendicular branches, and anastomose easily; the hyphal cells contain one to four nuclei. The anatomy of pink incrustation of fungus composed of four layers: 1. basal layer; 2. intermediate layer; 3. subhymenial layer; and 4. hymenial layer. From the results of both field and laboratory studies it is concluded that the fungus on the coffee leaf is actually the cobweb stage of pink fungus occurring on the leaves, and it is notorious fungus because it may act as inoculum source of pink disease.

Abstract

Using plant leaves such as banana leaves, glyricidia leaves, and rice straw for ripening resulted in lower ripening stage score than control or using chemical such as ethrel, although statistically they are not siginificantly different. Glyricidia leaves and rice straw inhibit disease symptom representing anthracnose (Colletotrichum musae) development on Gros-Michel banana.
