Macadamia Tree Health Initiative Amendments Act

This bill amends a 1990 agricultural law to establish a dedicated macadamia tree health initiative. It authorizes federal research grants for projects focused on combating pests and weeds affecting macadamia trees, including developing treatments, creating area-wide pest management programs, and studying tree biology and immune systems. The initiative also funds data collection on macadamia production and researches pesticide impacts on beneficial insects. This directly supports macadamia growers and researchers in affected regions (primarily Hawaii and California) through funding for fiscal years 2024-2035.
