Abstract

Repellency is one of strategies to reduce Diaphorina citri attack. Guava leaf extract (GLE) and horticultural mineral oil (HMO) are well-known as repellents against D. citri but have short persistence. This research was conducted to increase the persistence of GLE and HMO extracts by using simultaneous co-delivery as part of environmentally friendly control of D. citri. The treatments used were 5% GLE, 5% HMO, 5% GLE + 5% HMO, 5% encapsulated GLE, 5% encapsulated HMO, 5% encapsulated GLE + 5% encapsulated HMO, and aquadest as control. The result shows that 5% HMO, 5% GLE + 5% HMO, and 5% encapsulated GLE have a repellency effect on D. citri. In the non-encapsulated treatments, the percentage of D. citri stayed at treated citrus leaves increased significantly at 9 and 12 hours after application except 5% GLE + 5% HMO. Exposure to 5% GLE, 5% HMO, and 5% encapsulated GLE. The most dominant of GLE compounds was lactose and d-Glycero-l-gluco-heptose. The most dominant of HMO compounds were 17-Pentatriacontene, Tetrapentacontane 1,54-dibromo- and tert-Hexadecanethiol. Encapsulation of 5% GLE can increase the persistence of GLE as a repellent compound for D. citri, but this effect does not occur in HMOs.

Abstract

Colletotrichum spp are important post-harvest pathogens that frequently cause anthracnose and significant quality deterioration in citrus. This study were aimed to identify morphological characteristics and genetic confirmation of Colletotrichum isolates associated with mandarin citrus , as well as to evaluate the cross-inoculation potential of these isolates among five post-harvest commodities. Anthracnose-infected citrus fruits were collected from a local market in Central Java, Indonesia. Fungal isolation was conducted using the single-spore technique, and identification was based on colony and conidial characteristics, followed by PCR amplification with the universal ITS1 and ITS4 primers. Cross-inoculation tests were performed on five post-harvest commodities. Morphological and genetic characteristics indicated that the isolates referred to Colletotrichum gloeosporioides, the causal agent of anthracnose in mandarin citrus. Colony characters were white-greyish colour with velvety texture, conidiomata, black spots, concentric rings, and fast-growing group. Conidia were cylindrical with rounded ends, measuring 12.02µm in length and 4.23µm in width on average. ITS amplification yielded a ±570 bp fragment that showed 98% similarity to C. gloeosporioides isolates from China, indicating a close relationship with the C. gloeosporioides species complex. Cross-inoculation tests showed that C. gloeosporioides can cause anthracnose symptoms in tomato, cayenne, pepper, citrus, and mango. The finding highlights that C. gloeosporioides was detected on mandarin fruits exhibiting anthracnose symptoms, and the potency of the cross-inoculation assay revealed the broad host range of this fungus.
