Sažetak
Upotrebu pesticida neophodno je smanjiti na minimalne količine zbog proizvodnje zdrave hrane i održivosti poljoprivredne proizvodnje. Da bi se izvršila efikasna i ekonomična aplikacija pesticida na ratarskim poljoprivrednim kulturama, mora se posebno obratiti pažnja na uniformnost distribucije rasprskivača po širini radnog zahvata krila prskalice. Na uniformnost distribucije osim oblika mlaza prskalice utiče pritisak i način izbacivanja radne tečnosti kroz rasprskivač. U radu su dati rezultati ispitivanja tri različita tipa rasprskivača: sa ravnim mlazom, injektorski rasprskivač i injektorski rasprskivač sa dvostrukim mlazom. Poprečna distribucija merena je sprej skenerom pri tri različita pritiska na standardnoj visini od 0,5 m. Ugao rasprskivanja tečnosti iznosi 120o. Ispitivanje je izvršeno u laboratorijskim uslovima. Najbolju poprečnu distribuciju (horizontalnu distribuciju) odnosno koeficijent varijacije, ima rasprskivač IDK 120-04 pri najvećem ispitivanom pritisku od 4 bar. Statistički značajna razlika između oba injektorska rasprskivača nije zabeležena. Koeficijent varijacije standardnog rasprskivača bila je viša od 7 % što je u prihvatljivim okvirima. Povećanje pritiska uticalo je na uniformnost distribucije, koja se povećavala kod svih rasprskivača.
