The article reports that wine grape crops in northern San Joaquin Valley in California have developed earlier than normal in 2013. Wilber-Ellis Pest control adviser Jim Alfieri started to observe signs of powdery mildew in vines in early May. Alfieri's approach to protecting vines from the disease includes the use of a wettable sulfur and copper spray and dusting with sulfur. His approaches to controlling leafhoppers, omnivorous leafrollers and sour rot are also described.
