Abstract or Summary
  • There is a critical lack of economic information in the area of chemical weed control. This paper is intended to stimulate study in this area. The objective is to develop a method of economic analysis of alternative herbicide practices. The data used were taken from a Druchamp winter wheat trial conducted on the Hyslop Agronomy Research Station at Oregon State University in 1966. Diuron and linuron were used at four dosage levels at pre and postemergence. Production functions for the four herbicide treatments were determined for all alternatives. Price ratios of herbicide and wheat were used to determine points of profit maximization. Limits were established for levels of profitable herbicide use. Within these limits, alternatives may be selected depending on the prevailing price ratio conditions. The results from this analysis are in no way indications of recommended herbicide practice due to the experimental data used. One practice however, was found to be superior to all other alternatives in this problem analysis. In the concluding remarks, the values and limitations of this approach are discussed. The principal weakness is a lack of adequate information to be used by economic analyses. A discussion is included of economic aspects of herbicide use that have not been fully investigated. Suggestions are made for topics of future economic study that would be valuable contributions to the field of chemical weed control.
