Spraying is an important part of grape production and a high level of responsibility is attached to this operation. The following resources build on the work conducted by the Cooperative Research Centre for Viticulture (1996–2006) and provide information about various important factors that contribute to good spray application.
- Selecting and using spray adjuvants
- A single rate per hectare – why it shouldn’t be used
- Determining chemical rates for dilute and concentrate spraying
- Calculating chemical rates for vines
- Managing chemical resistance in the vineyard
- Determining dilute water volumes for spraying
- Equipment adjustment and evaluation to maximise spray coverage
- Understanding chemical ‘modes of action’
- Maintaining product performance in spray mixes
- Targeting sprays for vineyard pests and diseases
- Effective spray application (AWRI webinar 28 September 2017)
- Understanding fungicide resistance in Australian vineyards (AWRI webinar 27 August 2015)
