2. - Non-ideal conditions can cause foam marks to disappear before your next pass - Speed changes or crossing terraces can effect pattern of spray - Operator errors can cause overlapping or skips - Overlapping costs extra money, and in some cases damages crops - Skipping not only looks bad, but allows weeds that need to be killed to remain

3. First Things First Selecting the Right Nozzle

4. VMD= Volume Median Diameter which represents the droplet size where half of the spray volume droplets are smaller than the VMD and half of the spray volume droplets are larger than the VMD. TeeJet XR series nozzles Orifice sizes are color coded for easy identification Importance of pressure when considering when considering nozzles

12. Craig Day (Oklahoma Farmer) "We anxiously awaited the release of the Insight with DirectCommand because we felt it could easily pay for itself the first year, and after running it for one week we feel the return is already 50% on our investment. We run 130 foot boom on our sprayer and as fertilizer and chemical inputs keep going up, we need to have better boom section control on point rows. We went from our old system with two section boom control to the six section DirectCommand and can see where it easily saves us 6-8% in product."

13. The AIM Command computer uses the sprayer's servo valve or product pump to maintain constant pressure at the boom. The computer automatically adjusts the pulse width of the solenoid at the nozzle body to manage flow, ensuring a constant application rate at a constant pressure.
