Abstract:V vinogradu sorte Laški rizling smo izvedli poskus, kjer smo preučili učinek tipa šobe in izklapljanja ventilatorja aksialnega pršilnika na stopnjo učinkovitosti 3 akaricidov (endosulfan, fenazakvin in fenpiroksimat) za zatiranje pršice, povzročiteljice akarinoze. Testirali smo standardne šobe Albuz ATR in Lechler TR 80-02, ki dajejo drobne kapljice (VMD 100 – 150 µm) in antidriftne šobe Lechler ID 90-02, Albuz AVI in Lechler ITR 80-02, ki dajejo velike kapljice (VMD 400 – 700 µm). Uporaba antidriftnih šob z VMD nad 500 µm lahko zmanjša učinkovitosti akaricidov, če primerjamo z učinkovitostjo pri uporabi standardnih šob VMD 100 – 150 µm. Izklapljanje ventilatorja pri standardnih šobah ni zmanjšalo učinkovitosti akaricidov, pri antidriftnih šobah pa se je učinkovitost zmanjšala.

Title:INFLUENCE OF SPRAYER NOZZLE TYPES ON THE EFFICACY OF ACARICIDES APPLIED FOR CONTROLING THE GRAPEVINE RUST MITE (CALEPITRIMERUS VITIS NALEPA)
Abstract:A field trial was carried out in a vineyard with the Welsh Riesling grape variety to study the effects of nozzle types and the switching off the vineyard axial sprayer fan on the degree of efficacy of acaricides (endosulfan, fenazaquin and fenpyroximate) for controlling grape rust mite. Two standard nozzles (Albuz ATR in Lechler TR 80-02) which produce small droplets (VMD 100 – 150 µm) and their drift reducing nozzles (Lechler ID 90-02, Albuz AVI and Lechler ITR 80-02) which produce large droplets (VMD 400 – 700 µm) were studied. Using drift reducing nozzles that have a VMD higher than 500 µm, can decrease the efficacy of tested acaricides when compared with the efficacy produced with standard nozzles that have a VMD of 100 – 150 µm. Turning off the sprayer fan when using standard nozzles did not decrease the acaricide efficiency; when the drift reducing nozzles were used, turning of the sprayer fan resulted in a moderate decrease in the efficiency of acaricides.
