Impact: Agriculture and Food Systems

Relevance 

New York State agriculture faces ongoing threats from invasive pests and diseases that reduce crop yields, threaten poultry health, and disrupt farm viability. Invasive insects cost U.S. agriculture $13 billion annually, with significant risk to New York producers. Key threats include Highly Pathogenic Avian Influenza (HPAI), Swede midge in vegetable crops, and Spotted Lanternfly (SLF), which could result in more than $2 million in annual grape losses in the Finger Lakes region. Once established, these pests can cause substantial economic damage and undermine existing pest management systems, creating a need for coordinated research and education.r

Response

Cornell Cooperative Extension (CCE) led research and outreach to improve farmer preparedness and response to invasive pests. In southwest New York, CCE delivered two educational webinars reaching more than 700 participants, focusing on poultry production and HPAI prevention, with expertise from Cornell University and the New York State Department of Agriculture and Markets. For swede midge, CCE implemented a research and education program monitoring six farms, including three rural and three urban sites. Educators supported growers with pest monitoring, decision-making, netting installation, crop rotation, and the use of experimental ground barriers. These efforts were integrated into a broader educational campaign to promote effective pest management strategies.

Results

CCE programming increased farmer knowledge and adoption of pest management practices across multiple sectors. Swede midge management resulted in an estimated $7,510 per acre increase in sprouting broccoli yields. More than 700 poultry producers and residents improved their understanding of HPAI prevention, strengthening farm biosecurity and reducing risk of flock loss. Grape growers reported removal of alternate host species to reduce SLF risk and identified additional management actions for implementation. These outcomes improved pest control, reduced potential losses, and strengthened farm resilience.

Public Value

New York State benefits from a more resilient agricultural system capable of managing invasive pests and protecting food production. The state’s grape industry supports 79,000 jobs and contributes $6.65 billion annually, underscoring the importance of proactive pest management. By improving farmer preparedness and reducing production risks, Cornell Cooperative Extension helps protect economic activity, maintain open space, and ensure a stable supply of locally produced food.
