|a Breadfruit (Artocarpus altilis (Parkinson) Fosberg) is an important landscape and garden tree in Taiwan. During the spring of 2002, zonate leaf spots of breadfruit were observed at a Taipei nursery in northern Taiwan. Initially, several small, brown, zonate lesions developed on leaves. As lesions enlarged, they coalesced, leading to blighting of leaves and premature defoliation. Sporophores on the host were generally hypophyllous but sometimes amphigenous, solitary, erect, easily detachable, and as much as 850 μm long. The upper portion of the sporophore is considered an individual conidium and consisted of a pyramidal head that was fusiform to ventricose and cristulate, 495 to 534 μm long and 210 to 290 μm wide at the broadest point. Branches within the pyramidal head were short and compact, and dichotomously or trichotomously branched. The conidia were hyaline, broad, septate, tapering toward an acute apex, and sometimes constricted at the basal septum. Conidiophores were 400 to 680 × 20 to 100 μm. The fungus was isolated from infected tissue and maintained on potato dextrose agar (PDA). Sclerotia were produced on PDA after 4 to 5 weeks at 20°C without light, but conidia were not observed in culture. The fungus was identified as Cristulariella moricola (Hino) Redhead based on morphological characteristics (1,2). To complete Koch's postulates, three sporophores from infected leaves or three sclerotia from cultures were placed individually on each of 10 breadfruit leaves. The plants were placed in plastic bags and incubated at 16 to 20°C. Symptoms were observed after 2 to 3 days on 100% of plants inoculated with sporophores and after 6 days on 50% of plants inoculated with sclerotia. The pathogen was reisolated from lesions on plants inoculated with sporophores and sclerotia. No symptoms were observed on the control plants. C. moricola has been known to cause a bull's eye or zonate leaf spot and defoliation on woody and annual plants, including at least 51 host species and 36 families distributed in the central and eastern United States (1). To our knowledge, this is the first report of zonate leaf spot and defoliation of breadfruit caused by C. moricola. References: (1) T. T. Chang. Bull. Taiwan For. Res. Inst.
