Study of the efficiency of the perydroxan against Penicilliumitalicum and P. digitatum responsible for the decay of fruits of citrus fruits in preservation (Morocco)

Penicilliumitalicum and P. digitatum are the main fungal diseases capable of developing resistance to a wide variety of compounds fungicides of synthesis. This research project is interested in the study of the antifungal activity of a new product said Perydoxan against two phytopathogenic fungi Penicilliumitalicum and P. digitatum attacking the fruits of Citrus fruit in conservation of the Gharb region (Morocco). Different concentrations of Perydoxan have been tested for their inhibitory effects of the mycelial growth and spore germination in vitro and in vivo of P. italicum, and P. digitatum. In addition the mycelial growth of P. italicum was inhibited 100% at the dose of 2.5%. While the germination of the spores of P. digitatum was inhibited to 100% at the dose of 1.5% and for a duration of contact of 25min. This study shows that the Perydroxan presents a significant efficiency on the growth mycilienne and germination of the spores of fungi P. italicum and P. digitaum.
