When conditions favour it in Paris
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: ≥32°C · dry air ≤40%. 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.
How this compares
Of the 13 locations published here, Paris ranks 3 for hours favouring this disease in a year.
Watch it before you act
At this level the damage rarely costs the crop. Note the date, check twice a week, and act only if it reaches new growth or the weather turns favourable for it.
Scout the planting once temperatures pass 32°C, in dry air below 40%.
Not contagious. Nothing spreads from plant to plant here. Neighbouring plants showing the same signs are reacting to the same soil, water or weather, so fix the cause rather than isolating plants.
