5.3.1 DORMANT TO MID-SUMMER

Mealybugs & Soft scale

Dormant oil

5.3.5 PREHARVEST

Drosophila fruit flies, spotted wing drosophila

Fruit flies become active in the vineyard near and during harvest when ripe fruit is present. Several species of Drosophila fruit flies can be present, including the invasive spotted wing drosophila. The main threat from these fruit flies at this time is the potential to spread fruit rot organisms.

*Diazinon

Do not apply within 28 days of harvest. Do not apply within 18 days of harvest if a spreader sticker is used. Note that new *Diazinon labels do not include grape and therefore cannot be used. Product with older label that does include grape on label allowed.

Chemicals produced by adults can taint the flavor of juice. Threshold is approximately 2 beetles per kg (2.2 lbs.) fruit.
