Sensitivity of projected duration before resistance outbreak to weather, surface of non-crop refuge and compound efficacy.

Mean number of years for the resistant allele frequency to exceed 50% with a dominant resistance inheritance, 95% of WOSR and 4 treatment decision (C1: single calendar treatment; C2: double calendar treatment; HT: high threshold treatment; LT: low threshold treatment). Values in brackets indicate relative change in years from baseline simulations presented in Fig. 7.
