The VR sprayer performed well and adequately sprayed propyzamide on red sorrel (Rumex acetosella L.) and flumioxazin on moss (Polytrichum commune) within the selected wild blueberry fields. Results of T-test from experiment 1 suggested that the percent area coverage of water sensitive papers in target and non-target areas after the flumioxazin application was significant indicating SA technique using VR sprayer accurately applied the flumioxazin on targets. SA from experiment 2 resulted in a 69% reduction in propyzamide use with 25 cm before and after target buffer and 28% cover of red sorrel.
