When conditions favour it in Łódź
Hours in an average month when conditions meet every threshold this disease declares (2021–2025). Faded bars are months the database does not list the problem as active.
This disease's thresholds: 10–30°C. Every hour in the archive was tested against them.
These come from the ERA5 reanalysis on a roughly 9 km grid, so they describe the area rather than your plot. A shaded, sheltered corner holds leaf wetness longer than open ground, so conditions there can favour it more often than the figure suggests. This is a climate profile, not a forecast — the panel above carries the current risk.

Treat, then re-check in 5–7 days
Pick off the worst material, apply the organic option below, and look again after five to seven days. If the spread continued, escalate rather than repeating the same treatment.
Scout the planting while temperatures hold between 10°C and 30°C.
Carried by insects. An insect moves it plant to plant, so controlling the carrier matters as much as treating the symptom. Check for the vector before assuming the plants infected each other directly.
