Abstract
tomatoes are grown on more acreage in California than any other vegetable crop. Weed control costs amounted to $4.24 million, with additional losses from weeds estimated at $10.28 million -for a total cost of $14.5 million annually to tomato growers in California, according to the 1964. report of the Statewide Weed Control Committee of the State Chamber of Commerce. Current costs of weeding tomatoes are estimated at $27 per acre. These costs may increase : (1) if mechanical harvesting requires a longer period of weed control; and (2) if the labor for hand weeding becomes more scarce with the end of the bracero program.
