Effect of marigold leaf extract and captafol on fungal parasitism of root knot nematode eggs-Kenyan isolates

Abstract

Marigold leaf extract and captafol significantly inhibited fungal parasitism of Meloidogyne incognita and M. javanica eggs. Captafol treated eggs were the least parasitised. The highest concentration of extract had the second most significant inhibitory effect on egg parasitism. No significant difference in fungal egg parasitism of the two nematodes was detected in all treatments except at the lowest marigold extract concentration. Fungal parasitism of M. javanica eggs was significantly higher at this extract concentration. Fusarium so/ani and F. oxysporum differed in their ability to parasitize eggs. The former fungus was more parasitic than the latter.
