Phytoxic response and yield of soybean(glycine max)varieties treated with sulfentrazone or flumioxazin

摘要

Flumioxazin and sulfentrazone were compared for phytoxicity on 15 soybean varieties in a greenhouse study and four varieties in the field. In the greenhouse, injury from sulfentrazone was greater overall than with flumioxazin, 10/100 compared with 1/100, respectively, when averaged across varieties at the labelet rates. The varieties P9552, P91B01, and P9305 were more sensitive to sulfentrazone than the 11 other varieties on the basis of visible injury and plant height reductions.
