Now is also the time to continue with your disease monitoring and control options.
Before you next spray, take the time to walk through your vineyard and get inside the canopies to have a look for disease. Find out if you need to adjust your program before it is too late and bunches close. Controlling disease in closed bunches is near impossible.
We are near the time when berries are becoming resistant to disease, but this does not mean they magically throw off any disease that is already present, it means the berries are resistant to new disease infection from germinating spores.
Your best defences against most diseases are UV light and airflow so maintaining canopies with dappled light will be easier to control disease than canopies that are dense and layered.
Continue on with your protective spray program, paying particular attention to Powdery Mildew, but also be mindful of rapidly closing Withholding Period windows.
It looks like it may be another early harvest, and you don’t really want to get caught delaying your harvest due to a late spray with a product with a long WHP. You should be planning when you want to apply your last spray and still meet harvest date restrictions.
Irrigation management from this point on should be targeted at allowing the fruit to grow and ripen, but foliage levels should now be appropriate. That means applying enough water to maintain photosynthesis with enough transpiration to cope with warmer weather events, but not so much as to continue tip and cane growth.
