Researchers at the University of Florida have identified new species of nematodes that are harming the roots of tropical fruits such as pitahaya, guava, and passion fruit. These nematodes, which live in the soil, can cause yellowing of leaves, stunting of trees, and crop failure, and have not been previously identified by growers. The team, led by Abolfazl Hajihassani, has identified two root-knot nematode species, Meloidogyne enterolobii and Meloidogyne incognita, in guava and passion fruit orchards, respectively. These findings are crucial in developing control methods to protect these high-value crops and improving the sustainability of tropical fruit production in Florida. The researchers are also exploring the resistance of different cultivars and genotypes of guava and passion fruit to these nematodes, and looking for indigenous microbial agents for biological control.

Researchers at the University of Florida (UF) in the United States have identified the root causes that threaten the health and productivity of some of the state's most popular tropical fruits: pitahaya, guava and passion fruit. They found new species of microscopic roundworms, known as nematodes, that live in the soil and feed on roots. According to Abolfazl Hajihassani, an adjunct professor at the UF/IFAS Fort Lauderdale Research and Education Center, this marks an important step in creating control methods to safeguard the high-value crops of the Sunshine State's agriculture. "By surveying nurseries and farms, we found that more than 95% of growers were unaware of this problem and attributed yellowing of leaves, stunting of trees and even crop failure to water and nutrient deficiencies," he explains. “The findings are the puzzle pieces we were missing that will have important implications for agricultural practices and the sustainability of tropical fruit production in the ...
