Botrytis cinerea (teleomorph: Botryotinia fuckeliana) is an airborne plant pathogen with a necrotrophic lifestyle attacking over 200 crop hosts worldwide mainly dicotyledonous plant species. Although there are fungicides for its control, many classes of fungicides have failed due to its genetic plasticity. It causes soft rotting of all aerial plant parts, and rotting of vegetables, fruits and flowers post-harvest to produce prolific grey conidiophores and (macro) conidia typical of the disease. The antifungal effect of the CP 7.8 combinations that extracted from turmeric (Curcuma longa), were used for control of B. cinerea on strawberry, cabbage and rose in Sapa-Laocai and Hanoi. The results indicated that the CP 7.8, at 5,000ppm, had a fungistatic effect more than 75 percent on the grey mould disease and much higher than that of the other bioproduct TP-Zep 18EC and similar to that of Daconil 75WP. Taking into account the antifungal activity of the extracts from turmeric may be an promising products to control the phytopathogen B. cinerea.
