Growers should monitor their male vines for Psa-V infection and work to remove or reduce cankers where they occur. Cankers are Psa-V inoculum sources and create infection risk for male and female flower-buds. Infected male flowers can result in insufficient male pollen supply within the orchard and severely impact on orchard productivity. Where male plants are showing infection, assess pollen needs and make arrangements with your pollen provider now. Indications are that pollen availability is low this season.
