Abstract
Injury to corn (Zea maysL.) fromS-ethyl diisobutylthiocarbamate (butylate) was investigated with respect to hybrid. Field experiments in 1971 at Dillon and Clemson, South Carolina, established that the corn hybrid ‘Coker 71’ was more tolerant to butylate than ‘Pioneer 511A’. Also established as being tolerant and sensitive to butylate were the hybrids ‘Pioneer 3030’ and ‘PAG 644’, respectively. Laboratory studies with14C-butylate showed that the resistant hybrid ‘Pioneer 3030’ took up less14C-butylate and metabolized more to14CO2than did ‘PAG 644’.Keywords
