Time and Rate of Nicosulfuron Application in Peanut (Arachis hypogaea)

摘要

In field experiments conducted near Marianna, Trenton, and Archer, FL in 1990 and 1991, nicosulfuron applied 55 weeks after planting (WAP) at 18, 27, 36, or 54 g ai/ha injured peanut initially. When applied 7 WAP, only the two higher nicosulfuron rates injured peanut more than 10%. By 6 wk after application, crop injury was less than 8% for all treatments, except the highest (54 g/ha) rate. Nicosulfuron applied 5 or 7 WAP at 54 g/ha reduced peanut yield and sound mature kernels.
