abstract = "The effective implementation of chemical protection in fruit and grapevine
production is possible with use of technically correct orchard sprayer. The paper
presents the results obtained during the control testing of 41 different models of
orchard sprayers, with different period of exploitation in agricultural holdings across
Serbia that are used in intensive fruit and viticultural production. During the control
testing, a large number of parameters were monitored, using standardized methods
and test procedures. What is specifically analyzed in this paper is the technical
correctness of the manometer as a corrective device of the Measuring regulatory
system of the orchard sprayer. Checking the correctness of the manometer ensures
the appropriate working pressure of the liquid in the designed range, which
significantly improves the quality of chemical protection and extends the life of the
nozzle. Out of the total number of investigated orchard sprayers, 31% are in
exploitation for less than three years, while the largest number of orchard sprayers
ie. 44% is in exploitation for seven years or more. The technical correctness of the
manometer group 1 is at a high level (Cta= 0.80) compared to other groups of tested
orchard sprayers. Group 2 and group 3 have an identical coefficient of technical
accuracy of the manometer (Cta = 0.66 - 0.68). Low coefficient of technical accuracy
of the orchard sprayers manometer (Cta = 0.38) occurs in group 4, which shows the
direct dependence of the technical correctness of the manometer on the period of
exploitation of the orchard sprayer.",
