To help prevent powdery mildew on grapevines, it's best to spray the vines with Yates Liquid Copper when the shoots are 10cm long and repeat at 10-14 day intervals (or as necessary, if conditions favour infection). 

As for fruit fly, you can treat the lower leaves and stems with Yates Nature's Way Fruit Fly Control. Ensure you do not apply to the fruit.
