Pest and disease control is one of the most important technological links; otherwise the losses can be very high.Chemical control is the main method used in plant protection and for carrying out this work using specializedmachinery. Sprayers are equipped with different construction types of nozzles made of different materials resistant tocorrosion hydroabrasive to plant protection products. But with all their strength, their spray hole is decalibreate. Thus,the chemical solution will not effectively combat the diseases and pest, consumption of pesticide will be high. Thephytosanitary solution no longer reaches the plant pollute soil, residues having a negative impact on microorganisms.For this reason, it is recommended that before each campaign to combat pests and diseases, nozzles should be tested bymeasuring powder flow. To this end, on the sprayer for pest and disease control in vineyards TARAL 200 TURBOPITON were mounted two types of hydralic nozzles, one with full cone jet, and other with air absorption and flat fan jet.In this respect has been tested spraying machine, spraying the two ramps for different working pressures (0.2; 0.4; 0.6;0.8; 1.0; 1.2 and 1.4 MPa). Thus, for one minute, the flow rate of each nozzle was collected in the receptacle and thenmeasured with a graduated cylinder. After determining the flow uniformity was found that the nozzles have recordedover 95% uniformity.
