SOCIAL RETURNS TO DISEASE AND PARASITE CONTROL IN AGRICULTURE: WITCHWEED IN THE UNITED STATES

Peter M. Emerson and Gerald Plato

Journal of Agricultural Economics Research, 1978, vol. 30, issue 01, 8

Abstract: This study provides ex ante estimates of the value to society of the U.S. Department of Agriculture's witch· weed program. Program objectives are to contain and eradicate witchweed, a semiparasitic plant which reduces corn and grain sorghum yields. Critical elements which determine the social value are cost of the program, price elasticities of supply and demand, and shifts in supply occurring in the absence of a program.
