Spray Application Manual
Published: 6 Feb 2017
This Spray Application GrowNotes™ manual provides information on how various spraying systems and components work, along with those factors that the operator should consider to ensure the sprayer is operating to its full potential.
This new manual focuses on issues that will assist in maintaining the accuracy of the sprayer output while improving the efficiency and safety of spraying operations. It contains many useful tips for growers and spray operators.
The manual includes practical information – backed by science – on sprayer set-up, including self-propelled sprayers, new tools for determining sprayer outputs, advice for assessing spray coverage in the field, improving droplet capture by the target, drift-reducing equipment and techniques, the effects of adjuvant and nozzle type on drift potential, and surface temperature inversion research.
The manual comprises 23 modules and each of these features a series of videos to deliver advice to growers and spray operators in a visual, easy-to-digest manner.
Spray application expert Bill Gordon is the editor and lead author of the manual.
Mr Gordon is highly respected for his work in spray application and drift management in Australia over more than 20 years. He has delivered projects on behalf of the GRDC and other industry groups that have provided training on spraying best practice to more than 10,000 Australian grain growers.
Several other key industry players, from throughout Australia and overseas and with decades of experience in various aspects of spray application, have also contributed to production of the manual.
The Manual has the following sections which contain a number of modules which address the following issues:
- Planning your spray operations – things to think about
- Preparing for spraying – checks, accuracy and efficiency
- Spraying system – major components and set-up considerations
- Selecting a spraying system options available and operational considerations
- Review and planning for future needs
