Abstract

Spatial epidemiology of herbicide resistance is insufficiently understood at present to allow us to provide quantified strategies for farmers attempting to contain or eradicate patches of resistance. SHeRA, a spatially-explicit model of herbicide-resistant weeds in patches, is a useful new tool for developing efficient strategies using a zonal management approach.
