Effect of safener cyprosulfamide on isoxaflutole selectivity towards maize inbred lines.

Field trials were conducted in 2008 and 2009 to evaluate selectivity of isoxaflutole applied pre-emergence, and their mixture with safener cyprosulfamide towards fifteen maize inbred lines. The studied inbred lines responded differently to isoxaflutole, and the most susceptible lines in both years were popcorn inbreds 23 k NS and 24 k NS. The addition of cyprosulfamide proved effective in reducing phytotoxicity to maize inbred lines caused by isoxaflutole.
