Abstract

A statistical model of crop-weed competition is developed to permit, but not require, the existence of crop tolerance of weed pests. The popular rectangular hyperbolic model of crop-weed competition is shown to be a special case of the more comprehensive model. Application of the model to corn weed control in Massachusetts demonstrates its practicality and detects evidence of pest-tolerant crop response in this crop-weed system.
