Stemphylium Leaf Blight Overwintering Data from Ontario Weed Hosts

Two consecutive overwintering seasons (2021-2022 and 2022-2023) of data from an experiment investigating the survival of Stemphylium vesicarium on inoculated weed hosts under natural conditions in the Holland Marsh, Ontario. The dataset was created by Michael Kooy and published via Borealis Harvested Dataverse. It likely contains results from spray-inoculation trials assessing conidia detection and tissue decomposition across multiple weed species.

Use Cases

• Modeling the role of alternative weed hosts in disease epidemics based on conidia survival data.
• Comparing tissue decomposition rates among weed species over winter as described in the experiment.
• Informing integrated pest management strategies for Stemphylium leaf blight based on overwintering inoculum sources.

Strengths

• Data spans two consecutive overwintering seasons (2021-2022 and 2022-2023), allowing for temporal comparison.
• Experiment assessed ten weed species in the second trial with increased replication, suggesting a detailed comparison.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
