Summary: The study found that neem and pepper extracts can effectively control banana leaf spot disease, reduce the severity of black Sigatoka disease, and have no phytotoxic effects, though they do not significantly impact plant growth.

Summary: This study found a continuous range of sensitivity to sterol demethylation inhibitors in Pseudocercospora fijiensis field isolates collected from different banana production zones in various countries, with clear cross-sensitivity. Sequence analysis of PfCYP51 revealed 28 independent amino acid substitutions, nine of which correlated with reduced sensitivity to DMIs.

Summary: Banana Black Sigatoka (BBS) is a serious threat to banana production worldwide. A study in southern Ethiopia assessed 330 banana fields to determine the distribution and severity of BBS, as well as its association with agronomic practices and environmental factors. The results showed that BBS was widespread, with higher severity in one district compared to the other. Various variables, such as district, year, moisture source, plant material, cultivar, growth stage, cropping pattern, nutrient, sucker and disease management, and weed infestation had significant associations with BBS severity. Factors like cultivar resistance, mixed cropping, row planting, optimal plant density, good nutrient management, sucker and weed management, earthing up, and proper irrigation and drainage were identified as important management options.

Summary: The analysis of phyllosphere microbiomes traditionally relied on DNA extracted from whole leaves. Swabs collected from the adaxial and abaxial leaf surfaces of two garden plants, Rhapis excelsa and Cordyline fruticosa, showed that the abaxial surface had fewer bacteria compared to the adaxial surface. Our co-occurrence network analysis revealed that bacteria were predominantly found on the adaxial surface, while only a small group of leaf blotch fungi thrived on the abaxial surface. This suggests that the abaxial leaf surface has distinct characteristics and reduced microbial diversity, likely due to plant-microbe interactions.

Summary: Genetic diversity of black Sigatoka pathogen in East Africa was analyzed using molecular markers, revealing moderate genetic diversity within subpopulations and evidence of both clonal and sexual reproduction. Breeding efforts for resistance to P. fijiensis in East Africa need to account for intrapopulation variation to select durable resistant banana cultivars.

Summary: Rank-based data synthesis was used to assess the effect of climatic factors on the reaction of different Musa genotypes to black leaf streak disease. Differences in genotypic response were found between humid and dry environments. The information generated by the data synthesis supports further evaluation of Musa genotypes at new locations.

Summary: The study revealed a critical role for the PKS8-2 and PKS10-2 genes in the development of black Sigatoka disease in bananas, with a particularly significant impact observed for PKS10-2. While PKS8-2 also influences disease development, its specific role remains unclear.

Summary: Lecanosticta acicola is a pine needle pathogen causing considerable damage in North America, Europe, and Asia. This study used genetic markers to analyze the population of the pathogen and found multiple introduction events from North America to Europe. The pathogen spreads through both sexual and asexual reproduction, with intercontinental movement observed.

Summary: Accurately identifying disease types and vulnerable areas is crucial for effective crop production monitoring. In this study, we developed a framework for classifying and localizing maize leaf diseases using lightweight convolutional neural networks and interpretable AI algorithms, which achieved high accuracy and fast detection speeds.

Summary: The study found that different packaging materials did not significantly influence the bacterial community composition of tempeh, while there were differences in the quantity and composition of lactic acid bacteria in tempeh from different manufacturers. The results suggest that the quality of tempeh could be determined and improved based on these findings.

Summary: Microbiome analyses often overlook archaea and eukaryotes, focusing primarily on bacteria. However, due to difficulties in culturing these microorganisms, little is known about their relevance to human health and diseases. The use of next generation sequencing techniques has enabled a stronger focus on archaea and eukaryotes, but refinement is needed to achieve a holistic view of the microbiome.

Summary: The study developed a novel PCR-based method for the detection and differentiation of four species of Clarireedia associated with DS on turfgrass in China. Specific genes for each species were identified and used in a multiplex PCR assay. This method can rapidly and accurately detect and differentiate the four species of Clarireedia from pure cultures and infected turfgrass blades with DS symptoms.
