WAC 16-481-010   Establishing quarantine.  Grape phylloxera and the vine mealybug are insect pests injurious to grapevines. Grape phylloxera can cause severe reductions in grape yield and ultimately the death of the grapevine. This pest is widely distributed throughout the United States and the world. The vine mealybug injures grapevines by damaging grape bunches and transmitting grape viruses. Introductions of these pests into the state of Washington through infested grapevines, rootstock, and plant cuttings or on contaminated grape cultivation or harvesting equipment could have a severe economic impact on the Washington grape industry. The director, under the authority provided in chapters 17.24 and 15.13 RCW, has established a quarantine to prevent their introduction into the state.
