4-Row Spray Rig Recommendation (Santa Maria & Oxnard)
Our recommended manifold design is 8 nozzles per bed, spraying at a pressure of 108 psi. The recommended nozzle is Teejet Conejet Green TXR80036VK or an Albuz ATR80 Green with a hollow cone spray pattern. We evaluated this manifold design at a rate of 150 gpa and tractor speed of 2.88 mph. Results (n=25) show that using hollow cone Conejet nozzles, minimizing spray overlap, and positioning the nozzle closer to the canopy level can significantly increase coverage.
*Please note, proper maintenance, calibration, and spraying at canopy level ensures improved distribution uniformity and overall spray coverage.
