Faster is not better when it comes to spraying. Understand the impacts of travel speed on coverage and penetration.

The faster you can go, the faster you can get around the blocks when spraying. However, if you go too fast, you risk having the canopy not being properly penetrated by the sprayer, explains David Manktelow.

Grower stories

Escalating mealybug and scale populations and presented winegrape growers with a real challenge in recent seasons. Read about the range of strategies they have been using to meet this challenge.
Increased infestations of scale and the related sooty mould have been growing problems for South Australian winegrape growers in recent seasons
Viticulturists across Australia have a new tool at their disposal to tackle serious pests following the recent registration of Movento® 240 SC Insecticide for wine grapes.

There are some years in the game you just want to put behind you and move on, and 2016-17 was one of those for South Australian winegrape grower Andy Murdock, when winds and scale “hammered’’ a lot of the vines.

Protecting grape quality

Download this checklist for regular maintenance requirements and tick off the tasks that can make a big difference to the way your sprayer delivers spray to the vine canopy.
It’s not only powdery mildew and botrytis which can arrive as unwanted guests around Christmas time - insects can also join in on the vineyard festivities!
Flowering occurs from late October to late December, depending on variety and location, and it is arguably the most important time to protect and maintain vine health. 
Effective spray coverage is essential - this can be achieved by adjusting sprayer set up to target the canopy and bunches 
Weather conditions over the festive season can be very favourable for the spread of powdery mildew, often referred to as the ‘dry weather disease’, with young berries particularly susceptible to infection. 
Getting disease control right in vineyards is vital not only to maximise input efficiency and effectiveness, but also to optimise production and fruit quality. Viticulturists have plenty of things to consider when it comes to disease control, from chemical selection and rotation to spray interval management and application techniques.
