Efficacy of systemic fungicide metalaxyl for the control of downy mildew (Sclerospora graminicola) of pearl millet (Pennisetum glaucum) uri icon

abstract

  • Research on the control of this disease of P. glaucum is reviewed. All the formulations of metalaxyl tested as seed treatment or foliar spray controlled downy mildew with consequent increases in grain yield. Control depended on rate of application and on varietal susceptibility, more fungicide being required on more susceptible cultivars. Metalaxyl was toxic to germination when used at >2 g a.i./kg seed, particularly with the Apron 35 SD formulation, though cultivars differed in sensitivity. This fungistatic compound may be used to protect downy mildew susceptible cultivars in farmers'' fields and also in commercial seed production
