  1. SECTION 5 APPLICATION EQUIPMENT

  2. Home garden use Effect short term due to rain Produce to be washed Containers need to be resealed Duster Packs

  3. High concentration Chemical of low hazard 10-20 % coverage Each plant must be treated No drift Wick Wipers

  4. Squirt or Trigger packs • Home application • Ready to use • Absorption risk

  5. Aerosols • A number of household goods • Pressurised • Propellant often flammable • Convenient but expensive

  6. Backpacks • Hand operated pump sprayers. • Lever action or Trombone. • Range of nozzles can be used.

  7. Pneumatic Sprayers • Inexpensive garden variety • Stainless steel • Pressurised • OH&S risk when filling

  8. Controlled Droplet Applicators • Battery powered • Micron Herbie • Gravity feed onto spinning disc • Ultra Low Volume

  9. Enviromist and CDA

  10. High Pressure Hand Guns • Herbicide application to roadside vegetation, irrigation channels, areas of large weed populations such as Blackberry • Common with Council/Shire operations

  11. Boomsprays • Most common method of applying pesticides • Booms motorised or PTO driven • Tractor/vehicle mounted or trailing • Variety of shapes, sizes & configurations

  12. Boomspray

  13. Airblast Sprayer • Fan forced • Orchard application

  14. Nozzles for Hydraulic Sprayers • Hydraulic pressure most commonly-used spray method. • Compression sprayers, Knapsacks, Boomsprays & Air blast sprayers. • All nozzles prone to wear leading to inaccurate and wasteful application. • Replace nozzles which vary +/- 10%.

  15. Sintered Alumina Ceramic Hardened Stainless Steel Plastic/Nylon Stainless Steel Brass Aluminium Most Durable   Least Durable Nozzle Duribility

  16. Standard Flat Fan • Herbicides • Fan shaped pattern • Medium sized droplets • Spray angles 50-150°

  17. Even Flat Fan • Even Distribution • Medium sized droplets • Place herbicides in bands between row crops

  18. Turbo TeeJet® • Wide angle flat spray. • Large droplets to reduce drift. • Uniform distribution. • Pressure range 1-6 bar.

  19. Hollow Cone • Hollow cone pattern • Produces fine droplets • Insecticides & Fungicides

  20. Solid Cone • Solid cone pattern • Fine droplets • Insecticides & Fungicides • Used where chemical needs to be propelled over a distance

  21. Drift Management • Nozzle size • Pressure • Height of release (boom) • Weather • Shields

  22. Mechanical Pre-start Safety Check • CONTROLS • Brakes, clutch, steering. • Controls – PTO, gears etc • IMPLEMENT • Linkage adjustment. • Condition. • GUARDS • In place. • Secure. • PTO • Locking pin • Guard and cover. • Telescoping. • Condition. • TYRES and WHEELS • Tyre pressure. • Condition - cuts, cracks, embedded objects and wear. • Wheel nuts

  23. Chemical Application Safety Check • CHEMICAL PROTECTION • Sealed Cabin. • Charcoal filters. • PPE. • CONTROLS • Pressure gauge. • Valves DECONTAMINATION WASH DOWN • ACCESSORIES • Fittings • Leaks • MAINTENANCE • Hose condition: cracks, pinches, perished, leaks. • Tank: damage, wear, leaks, deterioration. • Nozzle condition: wear and blockages. • Filters: check seals and filter clogging.

  24. CALIBRATION 3 Measurements required: OUTPUT WIDTH SPEED

  25. WHY CALIBRATE ? The Right DOSE SAFETY Reduced costs Less chemical entering the environment Activity 5.5

  26. Managing a Spill • Isolate the spill. • Contain the spill. • Identify the chemical formulation spilled. • Clean-up the area affected by the spill. • Dispose of the chemical formulation spilled. • Notify the relevant authority.

  27. Containing the Spill

  28. Clean up and Disposal Rinse pad All gear used Rinse containers (x3) drumMUSTER Follow instructions Clean & store PPE Activity 5.6
