Abstract Not Available – First paragraph follows:
Precision cultivation and hand hoeing—the methods now used for weed control in lettuce production—become difficult where weed growth is thick and rapid. The lettuce may be overgrown to the point where cultivation is difficult and the lettuce suffers heavily from weed competition.
The Fujiwara Brothers, ranchers in the Chino area, cooperated in the experiment with CDEC.
The above progress report is based on Agricultural Extension Service Project No. 4188.
