- Observation Average disease prevalence across sites was 20%.
- Association Disease prevalence was positively associated with the percentage of vine mealybug-infested plants per site.
- Association Disease prevalence was positively associated with soil temperature.
- Association Disease prevalence was positively associated with accumulated heat units.
- Association Ambient temperature was negatively associated with disease prevalence.
- Observation Disease incidence increased by an average of 1.7% in 2022 across five vineyards.
- Observation Disease incidence increased by an average of 9% in 2023 across five vineyards.
- Association The site without vine mealybug had the lowest percentage of symptomatic plants.
- Association Cabernet Sauvignon and Nebbiolo showed more symptomatic plants than Merlot.
