DETERMINATION OF DISTRIBUTION UNIFORMITY FOR EEP-600 SPRAYER EQUIPED WITH IDK 120-02 NOZZLE
Nowadays, when Romania is a full member of the European Community, it is necessary to implement a system for testing and diagnose the spraying machines. In order to do this, there are special equipments that can tell to operator what is fault in a spraying machine. The parameters that the test stand can measure are: distribution uniformity which is tested for the whole width of the machine; the nozzle flow and all the correlations between the nozzles; the pump nominal pressure and flow. Using this state of the art equipment was possible to study the uniformity distribution for EEP-600 mounted sprayer, equipped with IDK 120-02 nozzle, for different working pressures and boom heights.
. ::: ::: 1 ::: Eggs of the mosquito Aedes punctor Kirby were found to be aggregated in a horizontal band within woodland depressions. ::: ::: 2 ::: The height of the peak of egg density above the lowest point in the depression varied from 24 to 39 cm in six transect studies. ::: ::: 3 ::: One depression, 2 m in diameter, was analysed in detail and found to contain a total of 9231 eggs with a maximum density of 944 eggs in a 250 cmz area.
