Tordon herbicide as a soil treatment for brush control
Down to Earth 19(4): 3-6
Tordon is a trade name for 3-amino 3,5,6-trichloropicolinic acid. Pelletized and granular formulations were applied to the soil in amounts ranging from 1 to 16 lbs./acre of the toxicant. In addition to pot tests field trials were conducted in 22 states; 37 woody species were involved. At 7 or more lbs./acre a high degree of control was obtained with most species. Spring and early summer applications gave better control than at other seasons.
