Iowa Harvest Underway
According to Mike White, Iowa State University Extension Viticulturalist, 80% of the crop in Iowa has now been harvested. Both yields and quality appear to favorable for 2011 he added. No early frost has been reported in Iowa. Rainfall was uneven across the state during the growing season, White remarked. The southern half of the state and especially the southeastern portions of Iowa endured heavy rain during July that created some disease pressure. “Vineyards that sprayed on time with fungicide did fine though,” White said.
Japanese beetles have now infiltrated the entire state, spreading east to west. 10% to 15% of Iowa vineyards were hit by beetles this year, he said. Spraying several times per year slowed down the pests White said.
