Western Farm Press Exclusive Insight;4/17/2012, p1
The author tackles the problem of heavy and dense foliage in vineyards. He explains that increasing crop production with too much spurs can be counterproductive as it decreases light penetration needed for cluster primordia initiation and good spray coverage for powdery mildew (PM) control as well as lead to overcropping and delayed bud break in the spring. He also offers tips for crop growers on how to reduce extra foliage and how to handle problems with PM.
