A fungicide with active ingredient fenhexamide for comparison andtwo lettuce cultivars Chianti and Yedikule were used through the experiments.Plant activator applications were carried out at interval of fourteen days withfive times using hand spray. After the third application, spore suspension ofpathogen (1x105 spore/ml) was inoculated to the leaves of theplants. Harpin protein application reduced the disease incidence on cultivars Chiantiand Yedikule at the rates of 57.50% and 68.75%; LaFü-be-mm at the rates of 30%and 57.50% respectively. Fenhexamid application had the highest effectivenesson both cultivars (90% and 92.50% for Chianti and Yedikule, respectively).However, there were statistically differences between activator applicationsand control treatment for disease incidence on both cultivars. This studysuggests promising results obtained with application of two activators toprevent grey mould disease in lettuce. CR - Akbudak N. ve Tezcan H. 2006.
