“…Except for the Satellite V trial that was affected by fire, E. pellita had a high survival rate, 76%-91%; in A. mangium it was only 34% at age 3 y. In this Core trial, crown damage by monkeys created portals of entry for attack by Ceratocystis mangenicans, a wilt and canker disease that leads to the death of A. mangium [39]. This limited the viability of its comparison with E. pellita to age 1.5 y when A. mangium had a similar stocking rate and 16% more standing volume.…”

Eucalyptus pellita has rapidly emerged as the species that has replaced Acacia mangium in broad-scale commercial plantations in Indonesia following widespread losses due to disease and in soils that have suffered a steady decline in phosphorus (P) under plantation forestry. Conversion from a nitrogen (N)-fixing to a non-N fixing species is expected to change the nutrient dynamics and the management required to maximise productivity. In this study in South Sumatra, responses of E. pellita to the application of N, P, potassium (K) and calcium (Ca) fertilisers were assessed at a number of trials on sites with varying site history; A. mangium was planted at one site to compare the species' responses to N and P. The growth of E. pellita responded significantly (p < 0.01) to P's application but not to N, K or Ca, with the addition of P increasing the stem volume by 32.6 m 3 ha −1 at 3 years of age compared with no addition of P fertiliser; the demand for P in the first two years of growth was, respectively, 4.8 and 6.8 kg ha −1 . This positive and large response appears to be because E. pellita has a lower efficiency in its use of P than A. mangium and is, therefore, more responsive than A. mangium to the addition of P. The reason for the lack of response to N remains unclear, although demand for N as well as K and Ca was high. These results suggest that sites recently converted to E. pellita from A. mangium and also new ex-native forest sites will be likely to only respond to P addition and that the response of E. pellita is likely to be greater than for A. mangium to maximise yield. At present, additional N, Ca or K fertilisers are not required, but this may change in the future.

“…However, the inoculated branch twigs in our experiments developed cankers and extensive wood discoloration. Overall, these symptoms are similar to those of many other tree diseases caused by Ceratocystis species, and the disease is best described as canker-wilt (Tsopelas et al, 2017;Nasution et al, 2019).…”

Ceratocystis ficicola causes vascular wilt of fig trees in Japan, invading root systems and the main stems eventually leading to tree death. In surveys from 2018 to 2020 in fig orchards in Greece, this fungus was detected in two separated regions. The fungus was consistently isolated from infected wood and from rhizosphere soil. The isolates were identified based on multi-locus phylogenetic analyses of rpb2, bt1 and tef1 gene regions and detailed morphological characteristics, including comparisons with an ex-type isolate of C. ficicola from Japan. The pathogenicity of Greek isolates was proven on Ficus carica and F. benjamina plants. Ceratocystis ficicola is a soil-borne pathogen, and the occurrence of vascular wilt outbreaks suggest that the pathogen spreads within and between orchards with infested soil and wood debris during ploughing. The pathogen is also spreading in Greece with infected propagation material. This is the first detailed report of C. ficicola outside Japan, and there is concern over potential spread of the pathogen to other Mediterranean countries, where approx. 70% of the world fig production occurs.

“…Squirrel attacks were not found on recently infected trees, suggesting the possible involvement of the wild vertebrate wounds on the massive disease spread in duku orchards. Vertebrate-incited wounds, such as those from squirrels and monkeys, are considered to contribute to the spread of Ceratocystis wilt on A. mangium plantations ( Brawner et al 2015 ; Hardie et al 2018 ; Nasution et al, 2019 ).…”

Identification and Characterization of Ceratocystis fimbriata Causing Lethal Wilt on the Lansium Tree in Indonesia

Bark canker, wood discoloration, and wilting of the duku tree ( Lansium domesticum ) along the watershed of Komering River, South Sumatra Province, Indonesia first appeared in 2013. The incidence of tree mortality was 100% within 3 years in badly infected orchards. A Ceratocystis species was consistently isolated from the diseased tissue and identified by morphological and sequence analyses of the internal transcribed spacer (ITS) and β-tubulin regions. Pathogenicity tests were conducted and Koch’s postulates were confirmed. The fungus was also pathogenic on Acacia mangium , but was less pathogenic on mango. Partial flooding was unfavourable for disease development. Two described isolates (WRC and WBC) had minor variation in morphology and DNA sequences, but the former exhibited a more pathogenic on both duku and acacia. The ITS phylogenies grouped the most pathogenic isolate (WRC) causing wilting of the duku tree within the aggressive and widely distributed ITS5 haplotype of C. fimbriata .
