Regardless of what part of the state a grape is grown in, the water situation is a huge question, says Gary Roberts, PCA with Wilbur-Ellis at Manteca, Calif.
â€śItâ€™s okay right now in this area, but they say itâ€™s going to be tight,â€ť he says. â€śGrowers will need to watch that situation pretty closely this year.
â€śChardonnay is out about four or five inches,â€ť says Roberts, â€śand weâ€™re starting to spray some sulfur.
â€śThere seems to be more and more vine mealybug showing up in this area. Itâ€™s going to be important to watch out for it, and train farm laborers how to look for it.â€ť
There are four mealybug species that can cause economic damage to California grape vineyards â€” grape mealybug, obscure mealybug, longtailed mealybug and vine mealybug. The vine mealybug is the most threatening.
