Description A large-scale field technique, based on preplanted infector rows that provide sporangial inoculum, is described for screening Pennisetum americanum for resistance to Sclerospora graminicola. It has been used to identify and improve resistance in composite varieties, cultivars and hybrid parents. The major advantages of the technique are reliability, uniformity of inoculum distribution, flexibility of site, flexibility of screening-plot size, effectiveness throughout the year (including the dry winter season) and independence of rainfall. ADDITIONAL ABSTRACT: The technique with Sclerospora graminicola on Pennisetum americanum, was based on preplanted infector rows that provide sporangial inoculum. Its advantages are reliability, uniformity of inoculum distribution, flexibility in location and size of screening plots, effectiveness throughout the year (including the dry winter season) and independence from rainfall
