Detection and identification of plant pathogenic fungi have relevant implications for both food safety human health, require fast easy-to handle diagnostic techniques. In this context, we report the design development a fluorescent array-based sensor, containing different organic receptors, able to detect selectively Penicillium italicum, Alternaria alternata Fusarium sacchari. The detection these can be performed using smartphone, leading first example microscopic fungal pathogens by array...
A dieback was observed on three-year-old pot-grown plants of Cycas revoluta in Sicily (Italy). Symptoms, including stunting, yellowing and blight the leaf crown, root rot internal browning decay basal stem, closely resembled Phytophthora crown syndrome, common other ornamentals. Isolations from rotten stem roots, using a selective medium, rhizosphere soil symptomatic plants, baiting, yielded three species, P. multivora, nicotianae pseudocryptogea, were obtained. Isolates identified by both...
Neofusicoccum parvum, in the family Botryosphaeriaceae, was identified as causal agent of bot gummosis lemon (Citrus × limon) trees, two major lemon-producing regions Italy. Gummy cankers on trunk and scaffold branches mature trees were most typical disease symptoms. parvum sole fungus constantly consistently isolated from canker bark symptomatic trees. It basis morphological characters phylogenetic analysis three loci, i.e., internal transcribed spacer nuclear ribosomal DNA (ITS) well...
24 °C in a humid chamber, controls remained asymptomatic.Alternaria alternata was re-isolated from symptomatic leaves.Similar leaf diseases caused by A. have been reported Turkey (Antalya province) and Libya (Castello et al. 2023).This is the first report of as carob pathogen Europe.
The possibility to detect the conservation status of citrus fruit by using an optical array sensor containing synthetic organic fluorescent probes is reported here. Our device shows high sensitivity and selectivity low-cost.
