Abstract

The potential impact of herbicide-tolerant winter oilseed rape (Brassica napus L,) on future herbicide use was investigated with a simulation model. The model uses a sigmoid function to simulate the growth of crops and weedsthat compete for a maximum yield potential. Thresholds for weed control are based upon critical levels of weed biomass, The dynamics of the weed population are determined by the efficacy of representative herbicides on individual weed species and by seedbank parameters. Herbicide efficacy is determined by a log-logistic dose-response curve for each species. Simulation of a rotation with winter oilseed rape/wheat/wheat/barley showed contradictorypredictions of herbicide use, because herbicide use in a rotation with either glyphosate- or glufosinate-tolerant oilseed rape was not reduced in theamount of kg a.i, ha(-1) compared with a traditional treatment, whereas the treatment frequency (number of standard recommended doses per unit area) decreased.
