Summary: Vegetable growers in the muck soil region of southwestern Quebec are threatened by soilborne diseases like bottom rot caused by Rhizoctonia solani, with disease severity increasing due to warm temperatures. This study identified Rhizoctonia solani AG 1-IB as the main cause of bottom rot in field-grown lettuce and developed specific qPCR assays for detection. The assays showed sensitivity in detecting the pathogen in plant tissue and soil samples, providing useful tools for lettuce bottom rot management.

Summary: The secretion of siderophores by Pseudomonas aeruginosa F2 and P. fluorescens JY3 was evaluated and found to have an inhibitory effect on Fusarium oxysporum and Rhizoctonia solani. Two optimized media were used to produce siderophores as biocontrol agents, and the cell-free supernatants containing siderophores were used to prepare bio-friendly formulations. These formulations showed significant reduction in damping-off caused by F. oxysporum and R. solani, as well as promoting the growth of wheat plants.

Summary: Cultivation of wild rocket as a baby-leaf vegetable is increasing due to its nutritional and taste qualities, but it is susceptible to soil-borne fungal diseases. Current disease management methods include synthetic fungicides and agro-ecological and biological approaches. This study explores the use of infrared thermography (IT) for early detection of rot diseases in wild rocket plants. Both active and passive thermographic methods were used to monitor leaves inoculated with soil-borne pathogens, and the results showed promising potential for early detection of these diseases.

Summary: Chemical pesticides have negative impacts on human health and the environment. Using plant extracts as natural chemicals can increase the efficiency of sustainable food production. This study found that an extract from Chorisia speciosa effectively protected tomato plants against Rhizoctonia solani, improving plant growth parameters and antioxidant enzyme production.

Summary: Pseudomonas fluorescens CFBP2392 has been found to have antibacterial and antifungal activities, and can effectively inhibit the growth of various plant pathogens and affect the ultrastructure of fungi. Genomic analysis identified multiple biosynthetic gene clusters involved in specialized metabolite production, providing a basis for further exploration of the potential of specialized metabolites in this strain.

Summary: Microbial interactions with plant roots play an important role in tomato plant growth and defense against Rhizoctonia solani. This study investigated the effects of two antagonistic bacteria on tomato rhizosphere soil and found that certain soil indicators and microbial functions were crucial for disease suppression. Metabolic profiling showed that carbon sources were essential in the interaction between plants, pathogens, and antagonists.

Summary: This study discovered an endophytic fungus, A. oryzae YRA3, isolated from a wild plant, which has biocontrol activity against Rhizoctonia root rot in sorghum. The chemical composition analysis revealed the presence of antifungal compounds in its metabolites. Greenhouse experiments showed that inoculating sorghum plants with A. oryzae YRA3 significantly reduced the severity of root rot and promoted plant growth.

Summary: The study found that the application of fragmented DNA at a concentration of 100 μg mL(-1) significantly increased the content of phenolic compounds and total flavonoids in chili pepper plants, and promoted gene expression associated with plant defense against wilt and root rot. Additionally, foliar application of DNA fragments of the pathogen complex decreased the mortality of infected plants by 40% at 30 days post-inoculation. These results suggest a potential application of fragmented DNA of these pathogens in agricultural crop protection strategies against wilt and root rot in Capsicum.

Summary: Alginate-based hydrogel adsorbents were developed for efficient removal of heavy metals from wastewater. The hydrogel beads prepared by blending bacterial alginate, polyvinyl alcohol, and chitosan exhibited excellent adsorption performance for Pb(II), Cd(II), and Cu(II). The addition of chitosan greatly improved the specific adsorption capacity for Cr(VI), and the hydrogels maintained a high adsorption capacity for heavy metals even after multiple cycles.

Summary: The study revealed that increasing inoculum density leads to decreased yield and quality in sugar beet, while cultivar susceptibility also impacts yield and quality. There was an interaction between inoculum density and cultivar susceptibility, with partially resistant cultivars showing lower disease ratings compared to moderate and susceptible cultivars, especially as inoculum density increased.

Summary: This study investigated the effectiveness of the fungicide Sedaxane as a seed treatment for oilseed rape. The results showed that all fungicide treatments, especially Thiram, greatly reduced the presence of Rhizoctonia DNA. Seedlings treated with Sedaxane exhibited significant root biostimulation in the presence of Rhizoctonia.
