BIOCONTROL OF RUST AND LEAF SPOTS DISEASES OF PEANUT USING CULTURE FILTRATES OF AKANTHOMYCESLECANIIIN NATURALCONDITIONS IN BURKINA FASO

Leaf spots and rust are the most destructive diseases of peanut in Tropical Africa, but it has shown that Akanthomyceslecanii isknown ashyperparasiteof rustandleaf fungi. Previous studies have investigated on use conidia A.lecaniiin biocontrol these diseases. However, influenced by temperature relative humidity, which could result low efficiency agents natural conditions. The secondary metabolites help to fight against plant Thus, we sprayed plants with culture filtrates from 21-day-old cultures two strains A. lecanii grown potato dextrose broth, assess their leaf innatural A susceptible variety SH470P a moderately varietyPC79-79 were used. Our findings revealed significantly reduced severity only. In SH470P, lowest 2020 (59.26%) 2021 (48.10%) recorded plots lecanii. lowestseverity (29.60%) was SH470P. From our findings, is promising alternative control spots. But, further required determine effective doses active
