Pri nanosu fitofarmacevtskega sredstva je poleg tehnično dobro narejene škropilnice zelo pomemben izbor pravih šob. Leta 2017 smo na delu Laboratorijskega polja Biotehniške fakultete v Ljubljani izvedli poskus, v katerem smo uporabili šobo z zmanjšanim zanašanjem z dvojnim asimetričnim curkom, Lechler IDTA 120-03 C. Posebnost te šobe sta kot sprednjega curka 30o od navpičnice in kot zadnjega curka 50o. Poleg tega gre spredaj 60 % volumskega pretoka, zadaj pa 40 %. Škropljenje smo izvedli v času cvetenja jare pšenice s fungicidom Prosaro. V poskusu smo uporabili tlak škropljenja 2,0 bar pri porabi vode 166 l/ha, 5,0 bar pri porabi vode 262 l/ha in 8,0 bar pri porabi vode 333 l/ha. Na klasu in listih jare pšenice smo ugotavljali kakovost nanosa z WSP lističi in količino depozita z UV barvilom. Najboljša kakovost nanosa tako na listih kot na klasu je bila dosežena pri tlaku škropljenja 5,0 bar, najslabša pa pri tlaku škropljenja 2,0 bar. Na zadnji strani klasa smo pri tem tlaku dosegli le 12 % pokritost. Pri tlaku škropljenja 5,0 bar in 8,0 bar smo dosegli precej večjo količino depozita tako na sprednji in na zadnji strani klasa kot pri tlaku škropljenja 2,0 bar.

Naslov:Deposit efficiency of IDTA 120-03 nozzle by spring wheat spraying using different pressures
Izvleček:
For good and sufficient application of phyto farmaceutical product is besides technicaly good sprayer, correct nozzle selection very important. In year 2017 a field trial was conducted on the Laboratory field of Biotechnical faculty in Ljubljana in which Lechler IDTA 120-03 C anti-drift nozzle with double asymmetrical flow was used. The special feature of this nozzle is an angle of front spray jet of 30o from vertical line and angle of back spray jet of 50o. Besides that, 60% of volume flow rate goes to front part and 40% of it goes to back part of nozzle. Spraying was carried out in the time of flowering of spring wheat with fungicide Prosaro. In trial three different pressures of spraying were used. The first pressure was 2,0 bar with water consumption of 166 l/ha, the second pressure used was 5,0 bar with water consumption of 262 l/ha and the last pressure was 8,0 bar with water consumption of 333 l/ha. On wheat head and leaves the deposit efficiency was analyzed with WSP and quantity of it with UV dye. The highest deposit quality was achieved with pressure of 5,0 bar both on head and leaves and the lowest quality was achieved with the spray pressure of 2,0 bar. Coverage of back site of wheat head was only 12% when using spray pressure of 2,0 bar. Quantity of deposit on back and front site of wheat head was much higher when pressure of spraying was 5,0 bar or 8,0 bar instead of 2,0 bar.
