Opis (eng)

The experiment on fungicide efficiency when controlling lettuce grey mold in dependance of irrigation mode, was made in the greenhouses in 2021. Under conditions of drip irrigation, the lowest percent (1.2%) of the diseased plants was revealed on the variant treated with the fungicide Switch. Of the treated variants, the highest infestation percent was recorded in the variant treated with Folio Gold (3.7%) whereas on the control variant without chemical treatment, 10.5% of the diseased plants was recorded. The disease intensity caused by B. cinerea on the control variant in the greenhouse experimental area with micro sprinkler greenhouse irrigation was 15.7%. The infection intensity with the chemically treated variants was reported to be the strongest on the variant treated with Teldor (7.0%) and the weakest on that treated with the fungicide Switch (3.2%). Thus, the most efficient fungicide for lettuce protection from B. cinerea proved to be Switch (88.1%). Comparatively highly efficient with grey mold control was also Signum (80.1%). Somewhat lower level of efficiency was exhibited by Folio Gold (64.3%) and Teldor (69.1%). The fungicide Switch showed the best results with grey mold control in lettuce (79.4%). Signum was also quite efficient (73.0%), with lower efficiency recorded on the variants treated with Folio Gold (61.9%) and Teldor (55.5%).
