Abstract:
The inoculation techniques of sorrrn graminearurn Schwabe,Fmonili formeSheld.and Iythiumsp,the three dominate pathogens causing corn stalk rot in HebeiProvince,and the resistance identification of cornarieties were studied.The results showedthat either single or mixture inoculation with the three pathogens could cause the typicalsymptom of corn stalk rot.And the pathogenesis rates of the mixture inoculation before,ceding and at 68 leaves stage were higher than that at the convention pollinating stage.ese reault can be used in identifying diseie resistance of corn varieties and selecting brid corn and selfbred line with resistance,to the three pathogens.
Key words:
Pathogen of corn stalk rot,
