Abstract Field experiments were conducted at nine locations in Texas and Georgia 2005 2006 to evaluate peanut tolerance lactofen. Lactofen 220 g ai/ha plus crop oil concentrate was applied 6 leaf (lf), lf followed by (fb) 15 days after the initial treatment (DAIT), DAIT alone, fb 30 DAIT, 45 60 alone weed-free plots. caused visible bronzing all locations. Yield loss observed when applications made a timing that would correspond plants R5 (beginning seed) R6 (full stage of growth. At except High Plains, this application within 90 d preharvest interval. Growers who apply lactofen early growing season small weeds should have confidence yields will not be negatively impacted despite dramatic above-ground injury symptoms; however, later season, during seed fill, may adversely affect yield.
