Abstract
The introduction of chemical weed-control, through the use of highly effective, selective and inexpensive hormone herbicides, permits profitable crop production in the tropics where old tools and methods, combined with an increase in labor costs, have created a serious problem of eradicating the luxuriant growth of tropical weeds.
