The direct injection systems for herbicide application keep the herbicide and
carriers (water) separetand meter and mix both on demand in the pipeline before entering
the nozzle. That makes possible varying of herbicide concentration without leaving
residues of pre-mixed solutions in the tank after operation. The ability to change the
chemicals and their concentration make the system suitable for site specific herbicide
application. As a consequence, there is a need to have a specific solution at the nozzle at
the correct time due to the spatial accuracy of the spray system. Sistemi za direktno injektiranje herbicida drže herbicid i nosač (voda) odvojeno
i mešaju ih neposredno pred razvodni sistem tj pred ulazak u raspršivač. Na taj način se
omogućava variranje koncentracije herbicida bez ostavljanja ostataka u toku predmešanja.
Mogućnost promene hemikata i njihovih koncentracija svrstava ovaj sistem u
jedan od tehničkih sistema lokalno-specifične aplikacije herbicida. Ovo ima za posledicu
distribuciju specifičnog rastvora, ka raspršivaču u određenom trenutku kako bi se
ostvarila adekvatna preciznost sistema aplikacije.
