Abstract(s) :

(Anglais) Objective: The control and treatment of food crops bacterial diseases remain problematic due to a scarcity of effective phytotreatments but traditional agricultural practices may represent an attractive venue to explore new treatments. Traditional practices were investigated in Madagascar with their effectiveness evaluated on potato cultures. Methods: A survey was conducted among Malagasy farmers to collect information on diseases observed on potato, rice and tomato crops and on eventual recourses to modern and/or traditional treatments. Twelve recipes against potato bacterial diseases were tested on 2 potato varieties, in experimental plots naturally infested by bacterial wilt disease. Results: The information collected from 52 farmers (i) showed that leaf spots and bacterial wilt disease are the most frequently identified threats for potato crops; and (ii) allowed to identify 54 traditional treatments, the majority of which are however no longer practiced. From the 12 tested recipes, 5 exhibit healing properties on potato bacterial wilt disease. Moreover, one (recipe R07) was effective on the two potato varieties (resistant and sensitive to fungal diseases) after 2 applications per week for 10 weeks, with 50% and 72% effectiveness rate, respectively. Conclusion: Valorization of traditional practices may provide an effective, safe, economic and standardized phytotreatment against potato bacterial wilt disease.
