Location: Temperate Tree Fruit and Vegetable Research
Project Number: 2092-22430-003-066-I
Project Type: Interagency Reimbursable Agreement
Start Date: Jun 1, 2025
End Date: May 31, 2026
Objective:
This project proposes to develop and evaluate netting protocols as a physical barrier to prevent insect vectors from transmitting X disease phytoplasma to cherry trees in nursery settings. The project will assess the effectiveness of different netting materials and mesh sizes in excluding insect vectors while maintaining adequate airflow and sunlight for tree growth. The expected outcome is a set of science-based recommendations for netting protocols that can be adopted by cherry nurseries to reduce the incidence of X disease phytoplasma and improve crop health.
Approach:
The project will involve a field experiment in which cherry trees will be enclosed in different types of netting materials with varying mesh sizes. The experiment will be conducted over one growing season to assess the effectiveness of each netting treatment in excluding insect vectors and preventing X disease phytoplasma transmission. Tree growth and health parameters will also be monitored to ensure that the netting does not negatively impact tree development. The data collected will be analyzed to determine the optimal netting material and mesh size for effective vector exclusion and tree health. The project will culminate in the development of science-based recommendations for netting protocols that can be easily adopted by cherry nurseries.
