Assuming that current levels of farm production are to be maintained, restricting the farm use of phenoxy herbicides would increase U.S. farmers direct production costs about $290 million. In addition, about 20 million more hours of family labor would be used. Net reductions in farm income would total $107 million for corn, $51 million for wheat, $8 million for rice, $28 million for other small grain, $11 million for sorghum, $33 million for pasture, $36 million for rangeland, and $16 million for other crops on which the phenoxys were used in 1966. The estimates were determined for each of the above crops by partial budgeting using cross-sectional data from the ERS Pesticide and General Farm Survey, 1966; Agricultural Statistics, 1968; and from Agricultural Research Service weed scientists.
