Abstract
In recent years, corn stem base rot has received less attention, primarily due to advancements in breeding activities. However, given the increasing climatic extremes and the intensification of cultivation technologies, it remains crucial to address this syndrome, as it significantly impacts yield. The inoculum persisting in the corn stalks left on the field poses a threat to subsequent crops in the crop rotation, increasing protection costs. The aim of our research was to rapidly and quantitatively assess the resistance of corn stalk rind under different tillage systems. Our results indicate that the severity of stem base infection varied across tillage practices. The lowest infection rate was observed in conventional tillage (12%), whereas strip-till systems exhibited significantly higher levels (24.5%). Although stalk breakage did not occur by the end of the growing season, plants affected by stem base rot produced 12.5% lower yields compared to healthy ones.
