520			_aThe most common symptoms occurring on over 1,000 maize (Zea mays L.) genotypes due both to natural and experimental barley yellow dwarf virus (BYDV) infections were leaf reddening on the tips of the basal leaves and longitudinal stripes. Fine chlorotic spots and broken chlorotic stripes were also observed. Similar discolorations were induced on the younger leaves by phosphorus deficiency. Frost induces a transient reddening on young virus-free maize plants, but the experimental induction of such damage to maize has not yet been successful. Leafhoppers, Zyginidia pullula Boheman, cause chlorotic spots on maize, also, but the distribution on the leaves is
