  1. PesticideApplication EquipmentPage 78General Manual

  2. To Enhance Safety and Benefits and to Get the Most From Any Sprayer: • Select the right equipment. • Set it up correctly. • Use proper operation procedures. • Perform proper maintenance.

  3. Reference Materials • The pesticide label • Spray equipment • BLM and Extension guidelines

  4. All Sprayers Should Be: • Durable • Convenient to fill • Convenient to operate • Easy to clean

  5. Three Basic Functions of a Sprayer: • Distribution & Metering • Determine the volume or weight that application equipment will apply to a known area under a given set of conditions. • Storage and transport CALIBRATION

  6. Types of Spray Equipment Hand sprayer Knapsack (LOK) Battery powered

  7. Low pressure hydraulic High pressure ULV Chemigation or injection

  8. Tanks • Fiberglass • Stainless steel • Galvanized steel • Aluminum • Polyethylene

  9. Lock Opening • Large Openings • Strainer For Filling • Agitation Device Large Drain

  10. Agitation

  11. 12 GPM for Boom50 GPM for agitation62 GPM total pump requirement Agitation Agitation Requirement5% of tank volume(5 gallons for each 100 gallons) 1000 gallon tank Pump - 50 GPM just for agitation

  12. Strainers • Tank opening • Basket Strainer (16-80 mesh) • In-line (40-50 mesh) • Nozzle screen (50 - 100 mesh)

  13. Pumps Must Provide • Gallons per minute (GPM) required by all nozzles • Tank agitation (5 - 6 % of tank volume) • Twenty percent (20%) reserve for wear

  14. Pump Types • Roller • Centrifugal • Gear • Turbine • Diaphragm • Piston

  15. Positive Displacement • General Purpose • Wide range • Output • Pressures • Herbicides • Rollers can wear Roller Pump

  16. Positive Displacement • High Pressure • Volume depends on RPMs • Insecticides • Dry Formulations • Part can wear Piston

  17. Positive Displacement • High Pressure • High Volume • Insecticides • Herbicides • Dry Formulations • Part can wear Diaphragm

  18. Non-positive Displacement • Continuous Flow • High RPM’s • Low Pressures • Durable • Easy to Maintain • Dry Formulations

  19. Pump requirement (GPM) = Desired GPA x Boom Width x MPH495 For Boom Flow only Add 5 GPM for every 100 gallons of tank – page 78

  20. Example 30 GPA x 40 feet x 5 MPH495 = 12 GPM

  21. Pressure • Least desirable to adjust GPA • 4 x pressure to double GPA • 20 GPA at 30 psi • 40 GPA at 120 psi Small droplets = DRIFT • Minor tweeks!

  22. Find New Pressure (psi)page 82 2 40 GPA20 GPA 2 35 psi X 35 X 2 35 X 4 New Pressure = 140 psi

  23. Hoses • Flexible (non-collapsible if suction hose) • Durable • Resistant (sunlight, oil, chemicals, abrasion, twisting) • Sufficient Pressure Rating • Correct size

  24. Guide for determining hose size.General Manual Page 88 Pump Output (gals/min.) Suction Hose Discharge Hose (inside diameter in inches) Under 12 GPM 3/4 5/8 12-25 GPM 1 3/4 25-50 GPM 1 1/4 1 50-100 GPM 1 1/2 1 1/4

  25. GPA – Gallons per Acre (GPA) • Total sprayer output, delivery rate, volume applied…ad nauseum • GPM – Gallons per Minute (GPM) • Nozzles and pump output • Diluent – dilutes formulation at applicatoin • Carrier – dilutes active ingredient at manufacture

  26. 2000 m - #2 Pencil lead 850 m - paper clip 420 m – staple 300 m - toothbrush bristle 150 m - sewing thread 100 m - human hair Comparison of Micron Sizes(approximate)

  27. What’s a good GPA? Very Fine to Fine Droplet = Low Volume (GPA) Medium to Coarse Droplets Very Coarse = High Volume

  28. Read them labels!!

  29. Three Functions of a Nozzle • Metering - GPA • Atomization – Liquid to drops • Pattern dispersal

  30. MAXIMIZING SPRAYER PERFORMANCE • Nozzle materials • Stainless steel, brass and plastic are the most common. • Stainless steel is probably the best choice

  31. Nozzles: Wear vs Cost

  32. VOLUME OF PESTICIDE SOLUTION APPLIED DEPENDS UPON: • NOZZLE TIPS • PRESSURE • SPEED • NOZZLE SPACING

  33. TeeJet nozzle tip examples

  34. NOZZLE TIP DESIGNATIONSSPRAYING SYSTEMS CO. • HSS8002E • HSS 80 02 E • HSS = HARDENED STAINLESS STEEL • 80 = 80 DEGREE SPRAY ANGLE • 02 = 0.2 GALLON PER MINUTE AT 40 PSI • E = EVEN FLAT FAN PATTERN FOR BAND APPLICATION

  35. Nozzle Coding- Spraying Systems • XR means eXtended Range • 80 means 80o pattern • 03 means 0.30 GPM at 40 psi • VS means Stainless Steel withVisiFlo color coding • SS = Stainless Steel • VP = Polymer, etc

  36. Atomization (Droplet Size) is Dependent On: • Nozzle type and orifice size • Pressure – higher pressure = small drops • Liquid characteristics

  37. Nozzle Types Flat fan - regular Flat fan - extended range Twin flat fan - good for dense foliage

  38. MAXIMIZING SPRAYER PERFORMANCE

  39. Nozzle Orientation

  40. Nozzle types Even flat fan - band applications Flooding flat fan Hollow cone Full cone

  41. Flood Jet

  42. MAXIMIZING SPRAYER PERFORMANCE • NOZZLES • Nozzle types • Flat fan is best for broadcast application of herbicides Flat fan Even fan

  43. BOOM BUSTERSPRAY NOZZLES THAT WORK WITHOUT BOOMS • FEATURES • All nozzles machined from solid stainless steel.  All have replaceable industrial grade nylon diffusers. (Tests have shown that this nylon will outlast stainless steel.)

  44. Roadside Spray Boom

  45. Boom Buster (con’t) • Extra wide spray pattern. • Excellent pattern and distribution. • All models spray chemicals and fertilizers. • All nozzles have standard pipe threads.

  46. Boom Buster (con’t) • USES • Row Crops, Grain and Pastures • State and County Right-of-Ways • Orchards and Vineyards • Forestry and Utility Right-of-Ways • Lawn and Turf • Roads, Hedge Rows and Fence Rows

  47. Rule of Thumb • An 8004 nozzle will deliver 40 gpa when used at 3 mph with 40 psi. • Likewise an 8002 will deliver 20 gpa under the same conditions. • An 8001 will deliver 10 gpa.
