Fungicides on soybeans provide growers an effective management strategy for foliar diseases, especially soybean rust. However, many questions about fungicides and how common practices affect fungicide efficacy are still unresolved. One possible cultural practice that may affect fungicide efficacy is plant population. Higher plant populations may provide a more conducive microenvironment for certain plant diseases and may reduce the penetration of fungicides to the lower canopy. The objective of these studies was to evaluate the efficacy of fungicides in different soybean plant populations.
