Abstract
Triclopyr, 2,4,5-T and 3,6-dichloropicolinic acid were applied at 0.002, 0.009, 0.03, 0.14 and 0.56 kg/ha to the foliage of the seedlings of 9 crop plants. In general, maize, oats, wheat, grain sorghum and kleingrass (Panicum coloratum) were more tolerant of the herbicides than were groundnuts, cotton, cucumber and soybean. At 0.14 and 0.56 kg/ha, triclopyr was more phytotoxic to maize, oats, sorghum and kleingrass than were 2,4,5-T and 3,6-dichloropicolinic acid, while few differences occurred among the herbicides at the lower rates. Kleingrass was not affected by 3,6-dichloropicolinic acid at any rate. Wheat was tolerant to most rates of all 3 herbicides. Triclopyr and 3,6-dichloropicolinic acid at 0.56 kg/ha caused greater injury to groundnuts than did 2,4,5-T, whereas 2,4,5-T and triclopyr were more damaging to cotton and cucumber than was 3,6-dichloropicolinic acid. All 3 herbicides at 0.14 and 0.56 kg/ha killed soybeans; at 0.002 to 0.03 kg/ha, soybean injury varied from none to severe. From summary
