Application Technology Flashcards
Importance of getting it right
Maximise benefits of chemical - cost effective
Minimise adverse affects
Good Practice
Use chemicals as part of IPM Select chem carefully - safety, residues, resistance, effectiveness Impliment for OHS Be aware of legal obligations Ensure competency Good application technology Clean up Monitor and keep records
Principle of chemical application
Minimal chemical for max effect
Chemical applicaiton
ID pest select right pesticide Select suitable equipment Conduct risk assessment set up Equipment Best time of applicaiton Decrease chem waste Label directions Clean up Records
Non spray application Methods
Spreader Wipers Fumigator Fogger Smoker Dips Bait stations Injectors - into trees Chemigators - add to irrigation water
Rate
Chemical per area rate
Dose
Chemical deposition per unit area
Coverage
% of target area reached
Factors affecting deposition on target
Velocity, droplet size, speed, volume
Uptake of chemical
Stress, humidity, temp, does, rain
Fine spray
Less than 100 micro mill
Coarse spray
Great that 300 micro mill
Size of droplets affects
Trajectory in air
drift potential
Evaporation potential
Decrease droplet size =
More numbers of droplets
more drift
Causes of drift
Inappropriate droplet size
Inappropriate equip set up
Inappropriate pesticide formation
Stayed in adverse weather
