dc.description.abstractZa pravilnu i uspešnu primenu pesticida od posebnog je značaja izvršiti izbor odgovarajućih rasprskivača. Takođe, rad sa odgovarajućim pritiskom ima veliki uticaj na efikasnost tretiranja. Koliko će tretiranje biti uspešno direktno zavisi od poprečne distribucije pesticida. Dobra poprečna distribucija znači: ujednačen oblik i veličinu kapi, smanjenje odnošenja kapljica vetrom (drift), ujednačena količina sredstva i ravnomerna raspodela kapi, a sve u cilju manje potrošnje korišćenog pesticida i manjih troškova tretiranja. Rasprskivači se, uglavnom, izrađuju za definisan radni pritisak, koji može da obezbedi potrebnu dezintegraciju kapljica. Da bi kvalitet zaštite bio dobar i vek rasprskivača duži, pritisak tečnosti mora da se održava u tolerantnim granicama. Sa povećanjem pritiska veličina kapljica se smanjuje. Poprečna distribucija unutar celookupnog posmatranog područja mora biti jednaka, te se izražava pomoću koeficijenta varijacije koji ne sme biti veći od 10%. U području potpunog prekrivanja površine tečnošću, izbačena količina tečnosti ne sme da odstupa više od 10%. Navedeno je od posebnog značaja u tretiranju uljane repice, kao kultura sa velikom ali tankom biljnom masom u završnim fazama razvoja. Dobijeni razultati trebalo bi da prikažu koji od četiri testirana tipa rasprskivača daje najbolje rezultate rada pri promeni pritiska.sr
dc.description.abstractFor the proper and successful use of pesticides it is especially important to select the appropriate sprayers. Also, working with appropriate pressure has a major impact on the effectiveness of treatment. How much treatment will be successfully done, directly depends on the transverse distribution of pesticides. Good cross distribution means: uniform shape and size of drops, drift reduction, uniform quantity of the product and even distribution of drops in order to reduce the consumption of pesticides and smaller treatments. Sprayers are mainly made for the defined operating pressure, which can provide the necessary disintegration of droplets. In order for the quality of protection to be good and the life of the sprayer longer, the pressure of the liquid must be maintained within tolerant limits. With the increase in pressure, the droplet size decreases. The transverse distribution within the entire observed area must be the same, expressed by the coefficient of variation, which must not be greater than 10%. In the area of total overlapping of the surface with liquid, the discharge of the liquid must not deviate more than 10%. The obtained results should show which of the four tested type of sprayer produces the best results in changing pressure.sr
