In order to research maize rough dwarf disease occurrence regularity and provide basis for agriculture meterological service and maize rough dwarf disease prevention and cure,author planted three corn varieties in 2014,used three different sowing date maize disease incidence of field experiment,observation,record and statistical analysis.The results were as follows :1different varieties and different seeding date,maize rough dwarf disease occurred.Sowing in June 5 had high incidence of about 10.0%,sowing in June 13,June 21,had the lower the incidence of more than 1.0%.2seed strain spike rate was low.Sowing in June 5,susceptible early and had panicle seed lowest rate(13.1%),sowing in June 5,June 13 had higher rate at 27.3%~44.4%.3seed strain into a spike amount generally was less than one-third of the normal. 4weather conditions was the main factor which affected maize rough dwarf disease.
