Chemical process to improve natural grapevine-cane extract effectivity against powdery mildew and grey mould
نویسندگان
چکیده
Grapevine canes are vine growing byproducts studied for their antimicrobial activities. These properties directly connected to the stilbene content; oligomeric stilbenes being most active. In this study, we propose a chemical process, based on oxidative coupling, using metals increase oligostilbene rate and biological effectivity of cane extract against grapevine pathogens. A total ten compounds were obtained identified by combining LCMS NMR spectroscopies, including four newly reported compounds: trans-oxistilbenin C, D, cis- E. The main formed evaluated preventive effects Plasmopara viticola Botrytis cinerea growth. processed was highly effective both

Biological control of the grapevine diseases 'grey mold' and 'powdery mildew' by Bacillus B27 and B29 strains.
Uncinula necator and Botrytis cinerea are the most destructive pathogens of the grapevine in Tunisia and elsewhere. We used two strains of Bacillus subtilis group, B27 and B29 to control powdery mildew and the grey mold disease of the grapevine. Green house experiments showed that B29 and B27 strains of the bacteria efficiently reduced the severity of powdery mildew up to 50% and 60%, respectiv...
متن کاملFenhexamid Resistance in the Botrytis Species Complex, Responsible for Grey Mould Disease
The three major fungal pests of grapevine, powdery and downy mildew and grey mould are mostly controlled through the application of fungicides. Some of those are particularly active against the grey mould agent Botrytis cinerea. The panel of fungicides authorized in France comprise since many years anilinopyrimidines, benzimidazoles, dithiocarbamates, dicarboximides, phenylpyrroles and pyridina...
متن کاملChemical suppressors of mlo-mediated powdery mildew resistance
Loss-of-function of barley mildew locus o (Mlo) confers durable broad-spectrum penetration resistance to the barley powdery mildew pathogen, Blumeria graminis f. sp. hordei (Bgh). Given the importance of mlo mutants in agriculture, surprisingly few molecular components have been identified to be required for this type of resistance in barley. With the aim to identify novel cellular factors cont...
متن کاملA Formally Designed Integrated Pest Management Decision Process against Grapevine Powdery and Downy Mildews
GrapeMilDeWS is an expert-based approach for the integrated pest management (IPM) of two of the major pathogens of grapevine (Vitis vinifera): Erysiphe necator which causes powdery mildew and Plasmopara viticola which causes downy mildew. GrapeMilDeWS has been designed and tested by a team of phytopathologists. It is presented here as a formal model in Statechart. We argue that formal modelling...
