From a humble beginning as ‘coffee shop’ discussion group by a handful of vineyard managers in 1996, Oregon’s LIVE (Low Input Viticulture and Enology) sustainability certification program has grown to encompass 8,000 acres of grapes and 97 vineyards - 44% of Oregon’s total grape acreage.

At 21 pages, this pdf document is lengthy, but packed with excellent information on:

  • Changes in fungicide registration, and relative efficacy/cost of different materials
  • Biology and control of major grape pathogens
  • ‘Putting it all together’ - an overview of fungicide choices based on vine development

Wayne incorporates the latest research results into this document every year. For example, this year’s version includes results of a study on UV light and powdery mildew development - which provides insight on weather-related differences in powdery mildew severity.

Here it is in PDF format:
