dc.description.abstract | The technical accuracy of the machine is a prerequisite for the effective
implementation of chemical protection in fruit and grapevine production. The paper
presents the results obtained during the control testing of 50 different models of
orchard sprayers, with different period of exploitation in growers throughout Serbia
that are used in intensive fruit and grapevine production. During the control testing, a
large number of parameters were monitored, using standardized methods and test
procedures. Comparison of the obtained data was applied to four groups of orchard
sprayers (defined by the period of the exploitation). The technical accuracy of the
individual orchard sprayer is expressed by the coefficient of the technical correctness
(Cta) according to individual marks of the tested parameters of orchard sprayers.
Out of the total number of investigated orchard sprayers, 12% of the orchard sprayers
are in exploitation for less than three years, while the largest number of orchard
sprayers, and 42% is in exploitation for seven years or more. The technical accuracy of
Group 1 orchard sprayers was sufficiently high, except for the parameters related to
the Measuring regulatory system (Cta = 0.80) and the Nozzles (Cta = 0.86). In Group 2,
a decrease in the coefficient of technical accuracy in all parameters was observed with
respect to the sprayers from Group 1, which was particularly pronounced for Agitators
(Cta = 0.50) and Nozzles (Cta = 0.68). The orchard sprayers from Group 3 are
characterized by a low coefficient of technical accuracy for the Nozzles (Cta = 0.37),
while Group 4 orchard sprayers have a very low coefficient of technical accuracy in all
tested parameters. The level of technical accuracy of the orchard sprayers used in
intensive fruit and grapevine production is directly dependent on the period of their
exploitation. | sr |
