Ustilago maydis,the
causal agent of maize smut disease, can cause significant yield losseson maize
under favorable conditions for the fungus. The aim of thestudy was to determine
yield losses due toU. maydis insome cultivars belonging to
different maize variety groups. Thus,a 2-year field
experiment was conducted in Antalya Province in 2010
and in2011.Inoculations of U. maydis were performed by injecting
inoculum into apical nodes of plants, 40- 60 cm high, and ear silk in inoculated plots. For each treatment, control
plots were also set up.Mean yield losses of the cultivars tested in 2010 and
2011 were at the rates of 22,3% and 46,3%, respectively. However, of all the
varieties, mean yield losses of the two-year varied from 23,1% to 41,4%.
The highest yield losseswere found on dent corn cultivars (Ada-523,
Pioneer-3394 and Side), whereas, the
lowest yield losses were on sweet corn variety, Merit.
