Abstract
MSMA, sodium cacodylate, diquat, aminotriazole, paraquat + surfactant, 2,4-0 amine, ametryne, and picram were tested for use as herbicides in forest plantations. MSMA gave best weed control per dollar of her bicide. Picram also gave good control on dry sites, although more expensive than MSMA, but damaged planted trees. When herbicides were applied during or just before a hard rain, none was satisfactory but paraquat was best. Complete control of weeds by cont act herbicides cannot exceed about two months, because within that time new plants replace those killed.
