|IMPACT: Virginia Winter Fruit School Impact||
Tree fruits are important to the agricultural economy in Virginia. The commonwealth ranks sixth in the nation in apple production, with a crop valued at more than $68 million, and 20th in peach production, with a crop valued at $4.5 million. Although smaller in acreage, cherries, pears, and plums also play an important role in some areas of Virginia. These fruit crops are susceptible to an everchanging array of insects, plant diseases, and weeds, and pest management programs are complex and knowledge-intensive.
