Abstract
Abstract The effects of five herbicides, simazine, terbacil, DP 733, trifluralin and dichlobenil were studied at two or three rates and three methods of placement around young apple and peach trees. Golden Delicious apple seedlings exhibited a greater inherent tolerance to the herbicides than June budded Candor peaches. Simazine, terbacil, and DP 733 significantly reduced the growth of both apples and peaches at all levels. Trifluralin and dichlobenil were toxic only when high rates were mixed in the soil around the tree root systems.
