Fourth Paragraph: The cultivation of wine grapes has become increasingly complex over the years. There have been refinements in tools and techniques which have included everything from rootstocks and clones to irrigation technology to advances in vineyard mechanization. We have gone from almost absolute reliance on a very short list of fungicides and insecticides to having an extensive collection of alternatives. Similarly, the list of previously unknown pests and diseases continues to grow. As the focus on wine quality has intensified we are challenged to produce even better quality grapes. Competition from other growing districts encourages us to redouble our efforts or fall behind.
