Weather stations in strawberry fields might seem like good sources of highly local environmental data, but this assumes sun, wind, and shade affect an area evenly. There can be microclimate variations at the canopy level, especially when row covers are used for plasticulture strawberry production.
Row covers serve an important purpose, since they can ward off freeze and frost damage during winter and early spring, and they may be needed to enhance plant growth during late fall. But they introduce a need to be more granular when taking weather measurements.
We found that canopy-level weather sensors produced different data when compared to nearby weather stations, and by conducting efficacy trials, we found that these differences play a role in designing effective fungicide treatments.
