Nutrient requirements on the farm are satisfied by primarily from the legume cover crop, but occasionally CAN-17 is applied to satisfy the nitrogen requirement. Soil, water, and tissue nutrient status is monitored intermittently. Pebble's Positive Points System score indicates that improvements in nutrient management can be made through a more regular monitoring program. He will share information with the Team regarding nutrient status and fertilizer management as it becomes available this year. No insecticide has been used on this vineyard in 18 years.
Mite pressure is low and is monitored by field monitoring.
There has never been a crop loss due to mite damage. Parasitic wasp populations are high in neighboring oak and coyote bush stands. Powdery mildew is controlled by sulfur. The Powdery Mildew Index, along with weather forecasts, are used as tools to schedule applications. Owl boxes and perches exist in the vineyard, although the oaks provide an excellent habitat for predatory birds.
