UF/IFAS research seeks new strategies against avocado diseases

The avocado industry in the United States is experiencing a surge in popularity, with demand rivaling that of the iconic American apple pie. However, this growing demand faces constant threats to production from diseases such as laurel wilt (LW) and Phytophthora root rot (PRR), which can devastate orchards if left unchecked.

To address this concern, scientists at the University of Florida are conducting a pioneering multi-state initiative to investigate LW and PRR. The goal of this survey is to gather critical data on growers' decision-making, economic implications, and management strategies. With this data, researchers aim to develop rational and sustainable disease management strategies tailored to the unique circumstances of each state.

The survey, which includes participation from various research institutions and universities across the United States, is aimed at avocado growers and other industry stakeholders. The deadline to participate in the survey is May 31, 2024.

Lichen White (LW), an invasive and lethal disease in the southeastern United States transmitted by a fungus carried by the ragweed beetle, has wreaked havoc on commercial avocado orchards since its detection in Florida in 2012. Meanwhile, PRR, which causes root rot in avocado trees and can lead to tree death if left untreated, poses a particularly serious threat given the importance of the Everglades restoration project, which could affect the plants' susceptibility to the disease.

With a national production of 149,600 tons in 2021, valued at $341.9 million, according to the U.S. Department of Agriculture's National Agricultural Statistics Service (USDA NAAS), the avocado industry is crucial for several states in the Southeast, with California, Florida, and Hawaii leading the way in terms of production.
