Abstract

A pot experiment was conducted at the Weed Science Station at the Department of Agronomy, University of the Philippines, Los Baños from April to September 1983. It aimed to identify the growth stage(s) of Commelina benghalensis that is susceptible to 2,4-D, to determine the optimum herbicide rate in each stage, and to evaluate the effect of 2,4-D at different growth stages of the weed.

Results of the experiment indicate that C. benghalensis was susceptible to 2,4-D but the susceptibility varied with the growth stage of the weed. The weed was more susceptible at the 4-5 leaf stage and beyond but tolerant at the earlier stages.

Effective and economical control of C. benghalensis with 2,4-D can be achieved with 0.5 kg/ha of the herbicide at the 4-5 and 6-7 leaf stages.
