Abstract


Grace grape (Uncinula necator) after the blight is the most important disease of grapes which causes great damage to this crop. This year work is done in order to research the most effective preparations to control the ash as well as assigning more sustainable cultivars to ash. The experiment is located in the municipality of Rahovec and cultivars Frankovka it in black and Burgundez was followed during 2013. For evaluating the effectiveness of the preparation and control of ash are using these chemical preparations: QUADRIS (Azoksistrobin), Falcon EC460 (tebuconazole, Triadimenol, Spiroxamin), COSA (prep. squfuri), Bayleton (Triadimefon). Karathane EC (Dinokap), Anvil (Heksakonazol), Rubigan (Fenarimol) and Saprol (Triforin). First spray against ash is made when shoots have reached 20 cm length. While the other sprays are made after every 12-15 days, splash total to six. Throughout vegetation made four assessments of disease, such as: first evaluation is done at the stage of entering the grains, then after every 15 to 20 days of an assessment. More resistant cultivar is shown Burgundezi ash black where the leaf disease index was 10.92 %, 20.36 % respectively in castles, while cultivar Frankovka had foliar disease index 15.95 %, respectively 25, and 29 % in the encampments. While regarding the efficacy of chemicals to control most successful ash are shown preparations that are used in variant B2 (Bayleton and Falcon EC460) where foliar disease index was 7.17 % and 12.71 % in the encampments. These results are highly significant compared with other options.

Keywords: vine grace, chemical preparations and varieties of grape.
