Influence of growth medium on antifungal activity of neem oil (<Emphasis Type="Italic">Azadirachta indica</Emphasis>) against <Emphasis Type="Italic">Lagenidium giganteum</Emphasis> and <Emphasis Type="Italic">Metarhizium anisopliae</Emphasis>

The inhibition of mycelial growth of Lagenidium giganteum by neem oil was lower than that of Metarhizium anisopliae in PYG and Emerson’s YpSs agar media. However, neem oil did not inhibit the mycelial growth of L. giganteum in sunflower seed extract agar medium, but did it inhibit the mycelial growth of M. anisopliae. The minimum inhibitory concentration of neem oil for L. giganteum was higher than that for M. anisopliae. The minimum fungicidal concentration of neem oil in PYG medium was lower than in YpSs for both fungi. The spores of L. giganteum grown in SFE medium could be used with neem oil for vector control.
