Our research in Oregon found that alternate year, light pruning is best. Also, cranberry fruit development in Oregon is different from many other production regions. Work on flower bud intiation and chilling and hardiness is underway in a cooperative study with a researcher in Massachusetts. Mulches did not differ in their effect on blueberry growth, development, or yield. The control plots in our study performed as well as mulched plots indicating growers have a low cost alternative.
Cold hardiness is also greater.
Blackberry genotypes were found to differ in percent drupelet set. Annual production in strawberry looks promising for reducing pest pressure, increasing average fruit size and reducing harvest labor costs. The discovery of grape phylloxera in a commercial vineyard in August 1990 was of major concern to the wine grape industry. This root-feeding insect will ultimately kill a susceptible grapevine. There is no chemical control for this pest.
