Fusarium longipes: a mycoparasite of Sclerospora graminicola on pearl millet uri icon

abstract

  • A mycoparasite, Fusor~urn longipes Wollenw. and Reinking, parasitizing Sclerospora graminicola,that causes downy mildew of pearl 'millet is reported. The mycoparasite attacks only downy mildew-infectedareas of the leaves. The mycoparasite produces brownish spots with variable sizes and may cover the entireinfected leaf under humid conditions resulting in the complete inhibition of sporangial produc~ion. Such plantsare killed immaturely. Attempts to selectively control the mycoparasite by the use of fungicide or to identifygenotypes which can support S. graminicola but not F. longipes have been unsuccessful
