Development and perfermance testing of a commercial variable rate sprayer for spot-application of agrochemicals in wild blueberry fields

Authors: Esau, T, Q Zaman, Y Chang, A Farooque, A Schumann
Description: Wild blueberry producers apply agrochemicals uniformly to control grasses, weeds, disease and other pests without considering the significant grass, weed and blueberry plant density variability within fields. The repeated and excessive use of agrochemicals in non target areas has resulted in an increased cost of production and environmental contamination. The objective of this study was to develop a commercial prototype variable rate (VR) sprayer and test for spot-application (SA) of herbicide and fungicide to control weeds and reduce disease pressures with minimal cost and environmental damage in wild blueberry fields. The 12.2 m VR sprayer was mounted on a John Deere 6430 farm tractor. The VR sprayer
