Statistical analysis of pest-tolerant crop response with reference to corn weed control

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...

Beschreibung
Zusammenfassung:	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.
