Fusarium solani is one of the most ruinous soil-borne pathogens and seriously affects crop yields quality worldwide. Ginger an important medicinal crop, ginger rhizome extract (GRE) has been used as alternative for chemical fungicides bactericides. We investigated fungistatic effect GRE on F. analyzed constituents using UPLC-MS/MS. Antifungal assay results showed that 20 mg/mL completely inhibi...

Rhizoctonia solani Kühn infects most plant families and can cause significant agricultural yield losses worldwide; however, plant resistance to this disease is rare and short-lived, and therefore poorly understood, resulting in the use of chemical pesticides for its control. Understanding the functional responses of this pathogen during host infection can help elucidate the molecular mechanisms...

Rice sheath blight disease caused by Rhizoctonia solani is one of the most devastating diseases in rice leading to heavy yield losses. Due to the polygenic nature of resistance, no major resistance gene with complete host resistance against R. solani has been reported. In this study, we have performed molecular and functional analysis of the genes associated with the major R. solani-resistance ...

The leaf pulp of Aloe vera Tourn. ex Linn., designated as the gel, and the bitter, yellow liquid fraction have been tested against pathogens (bacteria and fungi) affecting human and plants. However, their activity for fungal control in commercial industrial crops has not been determined. Thus, researchers at Mexico carried out studies to evaluate the inhibitory effect of Aloe pulp and liquid fr...

The soilborne fungus Rhizoctonia solani is a pathogen of many plants and causes severe damage in crops around the world. Strains of R. solani from the anastomosis group (AG) 3 attack potatoes, leading to great yield losses and to the downgrading of production. The study of the genetic diversity of the strains of R. solani in France allows the structure of the populations to be determined and ad...
