“…Monosporascus species are described as the causal agents of plant root rot and vine decline disease 37 ; the necrotrophic fungus Thanatephorus (anamorph Rhizoctonia) is the most important of the soil-borne pathogens that cause root rot, post emergence damping-off and fruit rot worldwide 38 ; and Curvularia is an agent causing leaf spot disease in many plants. [39][40][41] The abundance of two fungi beneficial to plants increased. Of these, ectomycorrhizal Hebeloma species are common in the cold regions of the world, and play a role in enhancing the cold tolerance of plants.…”

BACKGROUNDBacillus, as a plant‐growth‐promoting rhizobacteria, can enhance the resistance of plants to phytopathogens. So, in our study, the excellent biocontrol Bacillus strains were screened and used to control ginkgo leaf blight (Alternaria tenuissima).RESULTSFour biocontrol Bacillus strains—Bsa537, Bam337, Bso544, and Bsu503—were selected from 286 isolates based on their capacity to inhibit pathogens and promote plant growth. They significantly improved the resistance of ginkgo to leaf blight, especially the mixture of four Bacillus strains, which contributed to the decrease in lesion areas by more than 40%. Hence, a mixture of Bacillus strains was used to control ginkgo leaf blight in the field. Treatment efficiency varied from 30% to 100% (average 81.5%) and was higher than that of the control (from −2% to −18%, average − 8.5%), the antioxidant capacity of the treated ginkgo was also stronger. Additionally, ginkgo biomass rose as a result of treatment with the Bacillus mixture, including leaf weight, area, thickness, number of lateral roots, and root weight. Furthermore, the Bacillus mixture improved the ginkgo rhizosphere soil by boosting the number of beneficial microorganisms, lowering the number of pathogens, and quickening soil catabolism.BACKGROUNDThe Bacillus mixture improved the health status of ginkgo by protecting it from pathogen attack, promoting its growth, improving microorganism community in rhizosphere. This work closes a technological gap in biological control of ginkgo leaf blight, investigates the application methods of compound Bacillus biofertilizers, and establishes a framework for the population and commercialization of these products.This article is protected by copyright.

A leaf spot disease affecting Curcuma kwangsiensis (Zingiberaceae) has been observed in Qinzhou City, Guangxi Province. Infected leaves exhibit yellow-brown spots that progressively expand and eventually lead to leaf death. Curvularia isolates were obtained from the diseased leaves with tissue isolation and single spore purification methods. To accurately identify these isolates, we analyzed their morphological characteristics and phylogenetic relationships using combinations of ITS, GAPDH , and EF-1α gene sequences. Phylogenetic analysis showed that the investigated strains formed a distinct clade separate from other recognized Curvularia species. Furthermore, the strains exhibited differences in conidiophore size and conidia shape/size. Based on phylogenetic studies, morphology, and pathogenicity tests, the pathogen was identified as a new species named Curvularia qinzhouensis . Optimal conditions for mycelial growth were observed at 30 °C and pH 8. The sensitivity of the pathogen to various phytochemicals was also examined. Honokiol, thymol, and citral demonstrated effective antifungal effects, with EC 50 values of 6.72 ± 1.75, 25.74 ± 4.30, and 54.24 ± 4.69 µg/ml, respectively. The present investigation provides the first report of leaf spot disease on C. kwangsiensis caused by C. qinzhouensis , and valuable insights for the prevention and control of this disease.
