We present a protocol for constructing a simple spore-distribution system consisting of an inoculation box with a ~50 µm mesh and a transparent plastic chamber. This can be used to evenly inoculate plants with powdery mildew spores, thereby enabling accurate and reproducible assessment of disease phenotypes of plants under study.
