We have a 3pt tractor mounted 100 gal tank, 18 ft boom, 6 nozzles and a 6 roller pump. We will change out nozzles depending on desired droplet size. A flood tip is used when a coarser droplet is desired and a flat spray tip is used for a fine mist. When 501 is sprayed, it is directed upward and not directly on the plant. For 500, and any other foliar or soil applications, they are directed downward in a typical row crop spray set up. The psi is kept under 30. Application rate is achieved based on nozzle tip size, psi, ground speed and the number nozzles. I understand a roller pump is not ideal for spraying living materials, but parts and the pump itself are locally available, so that is what we go with. However, it would be great to hear more about the benefits of diaphragm pumps. I also filter before adding to the spray tank. 50 mesh seems adequate as long as the filters before the nozzle are not greater than 50 mesh. In a pinch burlap has also worked for filtering while adding to the tank.
Initial investment is about $2500 for this type of setup.
Best of luck!
