摘要

Site-specific weed management is one of the potential ways to reduce the chemical amount required to control crop weeds. Sources of optimization were investigated with spray swath from an individual nozzle or a boom section width and spray depositionpatterns were applied to different spatial coverage rates of weeds. The objective is to quantify herbicide saving possibilities as well as potential under-application areas. Simulations were performed with a collection of virtual weed infestation maps and an actual infestation map derived from aerial images. Results issued from the computation were expressed in terms of three indicators: i) the ratio between herbicide amount in the case of a targeted application and the amount deposited in the case of afull application, ii) the proportion of weed coverage on which the application rate is higher than 85% of the rated dosage, iii) the proportion of the weed area on which the deposited application rate is lower than 50% of the rated dosage.
