“…In China, C. fructicola was reported to be associated with bergamot orange ( Citrus bergamia ), pomelo ( C. grandis ), mandarin ( C. reticulata cv. nanfengmiju), oranges ( C. sinensis ), and kumquat ( Fortunella margarita ) [ 26 , 27 , 30 ]. Colletotrichum fructicola was found to cause both preharvest and postharvest citrus disease in Australia.…”

Colletotrichum spp. are important pathogens of citrus that cause dieback of branches and postharvest disease. Globally, several species of Colletotrichum have been identified as causing anthracnose of citrus. One hundred and sixty-eight Colletotrichum isolates were collected from anthracnose symptoms on citrus stems, leaves, and fruit from Victoria, New South Wales, and Queensland, and from State herbaria in Australia. Colletotrichum australianum sp. nov., C. fructicola, C. gloeosporioides, C. karstii, C. siamense, and C. theobromicola were identified using multi-gene phylogenetic analyses based on seven genomic loci (ITS, gapdh, act, tub2, ApMat, gs, and chs-1) in the gloeosporioides complex and five genomic loci (ITS, tub2, act, chs-1, and his3) in the boninense complex, as well as morphological characters. Several isolates pathogenic to chili (Capsicum annuum), previously identified as C. queenslandicum, formed a clade with the citrus isolates described here as C. australianum sp. nov. The spore shape and culture characteristics of the chili and citrus isolates of C. australianum were similar and differed from those of C. queenslandicum. This is the first report of C. theobromicola isolated from citrus and the first detection of C. karstii and C. siamense associated with citrus anthracnose in Australia.

“…Acidic electrolyzed water can completely be degraded after use without generating chlorine residue in food. In recent years, acidic electrolyzed water has emerged as a novel fungicide in storage and fresh-keeping of all kinds of fruits and vegetables, owing to its safe, minimal pollutant, non-residue, non-toxic, simple formulation, and cost-effective properties (Hu et al, 2019;Puglisi et al, 2017;Chen et al, 2020). Its e cacy extends beyond the elimination of pathogenic bacteria , demonstrating the ability to inhibit fungal growth.…”

This study focused on the identification of rot-causing fungi in tangelo, with a particular emphasis on investigating the inhibitory effects of acidic electrolyzed water on the identified pathogens. The dominant strains responsible for postharvest decay were isolated from infected tangelo fruits and characterized through morphological observation, molecular identification, and pathogenicity detection. Two strains were isolated from postharvest diseased tangelo fruits, cultured and morphologically characterized, and had their gene fragments amplified using primers ITS1 and ITS4. The results revealed the rDNA-ITS sequence of TF1 and TF2 were 100% homologous with those of Penicillium citrinum and Aspergillus sydowii. These isolated fungi were confirmed to induce tangelo disease, and subsequent re-isolation validated their consistency with the inoculum. Antifungal tests demonstrated that acidic electrolyzed water exhibited a potent inhibitory effect on Penicillium citrinum and Aspergillus sydowii, with EC50 values of 85.4 µg/mL and 60.12 µg/mL, respectively. The inhibition zones of 150 µg/mL acidic electrolyzed water to 2 kinds of pathogenic fungi were over 75 mm in diameter. Furthermore, treatment with acidic electrolyzed water resulted in morphological changes such as bending and shrinking of the fungal hyphae surface. In addition, extracellular pH, conductivity, and absorbance at 260 nm of the fungi hypha significantly increased post-treatment with acidic electrolyzed water. Pathogenic morphology and IST sequencing analysis confirmed Penicillium citrinum and Aspergillus sydowii as the primary pathogenic fungi, with their growth effectively inhibited by acidic electrolytic water.

“…Thus, a broad number of species of Colletotrichum was reported in association with Citrus spp. over the world [19][20][21][22][23][24]. Colletotrichum gloeosporioides and C. abscissum (previously reported as C. acutatum) are the causal agents of petal necrosis, abscission of young fruit, and the formation of persistent calyces of various Citrus species as a disease complex known as postbloom fruit drop in Brazil [3,25] and Bermuda [26].…”

An Eleven-Year Survey on Field Disease Susceptibility of Citrus Accessions to Colletotrichum and Alternaria Species

et al. 2021

In the past decade Colletotrichum gloeosporioides, C. karstii, and Alternaria alternata represent emerging fungal pathogens on citrus in the Mediterranean basin. Selection of tolerant Citrus germplasm offers evaluable long-term solution and should be considered as promising alternative to limit synthetic fungicide application to manage Alternaria and Colletotrichum infections in Citrus groves. In this study, the high variability of pre-harvest disease symptoms among 37 Citrus accessions was investigated in Italy in the most representative Sicilian production districts covering 1500 ha and including 20 homogeneous areas over an eleven-year survey period (2010–2020). Early fruit drop, brown spot, and anthracnose on fruit and leaves, pre-harvest fruit drop, and twig blight and defoliation associated to Alternaria and Colletotrichum spp. were identified on oranges, mandarins, and lemons. Comprehensively, first extensive data obtained herein on field susceptibility within “Tarocco” blood orange group to above disease symptoms clearly indicate as “Tarocco Nucellare 57-1E-1,” “Tarocco Tapi,” “Tarocco Sant’Alfio,” and “Tarocco Catania” accessions should be preferred to remaining Tarocco ones. A broad degree of tolerance or susceptibility was also observed within other Citrus group as it happens for tolerant lemon “Femminello Zagara Bianca,” thus demonstrating a putative resource for further studies to employ in a breeding program for genetic improvement of Citrus.
