توضیح
Timely herbicide application is a key factor in herbicide efficiency that may provide some possibility of reducing herbicide dose. Field experiments were conducted to study the interactive effect of dose of the herbicide mesosulfuron‐methyl and application timing on the control of Bromus japonicas in wheat. Herbicide application timings were based on Zadoks growth stages of wheat. An empirical model was developed for deciding herbicide dose. Relationships between herbicide dose and weed biomass were described with the standard dose–response model at each application time. Parameter estimates suggested a linear increase in parameters W0 (weed biomass with no herbicide treatment) and ED50 (herbicide dose required for 50% reduction in W0) with thermal time. A combined dose–response (CDR) model, with W0 and ED50 being replaced by their linear relationships with thermal time, was used for …
