AB  - Protective fungicides are sensitive to environmental conditions such as rainfall and solar radiation. Therefore, it is important to prolong the biological activity and fungicide resistance to the above-mentioned factors that can be achieved by adding a wetting agent to the working solution. Additionally, the quality and efficiency of preventive contact fungicides significantly depend on the application technique. Thus, it is important to make the right choice of the nozzles and adjust the working parameters of the treatment. The aim of this work is to determine the influence of a wetting agent and type of nozzle on copper hydroxide (2 L ha−2) deposits on sugar beet leaves. Experiments are set up under laboratory and field conditions. A pinole-based wetting agent is applied at three rates (0.3, 0.6, and 1.0 L ha−1) and two types of nozzles are used (standard with flat jet and modern turbo-drop twin-jet). A brilliant blue tracer is added to a working solution to enable the measurement of copper hydroxide deposits. The deposit amount is recorded before and after the rain simulation (15 L m−2) with a spectrophotometer light beam. In order to ensure the timeliness of the application of fungicides, remote sensing of vegetative indices is used as an indicator of disease occurrence. The results indicated an increase in copper hydroxide deposits with the increase in wetting agent rates for both types of nozzles and in both laboratory and field experiments. Moreover, when applying the copper hydroxide mixtures with modern turbo drop nozzles, the increase in copper hydroxide deposit is significant, compared to the standard nozzles.

AB  - Za 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.
AB  - For 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.
