e0“Downy mildew developed in four of the five trials, and disease intensity was always lower under drip irrigation than under furrow irrigation.”
e1“Microclimates and downy mildew (caused by Bremia lactucae) disease progress were monitored in neighboring lettuce fields with subsurface drip or furrow irrigation during five trials in 1992 to 1993.”
e2“The magnitude of the differences in disease was small, however.”

- Intervention effect Before irrigation, measured microclimate did not differ significantly between methods.
- Intervention effect Furrow irrigation produced longer overall leaf wetness periods within three days.
- Intervention effect Furrow irrigation showed a trend toward higher daytime humidity.
- Intervention effect Furrow irrigation showed a trend toward longer morning leaf wetness periods.
- Intervention effect Air temperature and nighttime humidity did not differ consistently between irrigation methods.
- Observation Downy mildew developed in four of five lettuce trials.
- Observation Authors infer that mesoclimatic variation generally outweighs microclimate changes relevant to disease in coastal California.
