DescriptionOhia trees less than 6 inches d .b.h. on the island of Hawaii were killed by injection of undiluted 2,4.S-T ester. This chemical was less effective on larger trees. Injections applied in September and January were more effective than the May applications. Injections of 2,4-D were relatively ineffective, any season of the year, even for small trees. Tardon 22K proved 100 percent effective in a single, unreplicated trial.
