Prevention and Control
Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Pesticides should always be used in a lawful manner, consistent with the product’s label.
Physical/Mechanical Control
Physical control methods such as cutting down or frilling (removal of bark completely around the base of the tree trunk) have been used in combination with herbicide applications in vigorous efforts to control some Syzygium species that have proved invasive threats to native flora in places such as Hawaii, the Galapagos Islands, and Pitcairn Islands. Physical removal of trees and replacing them with native species has also been a reported method for an invasive Syzygium species (S. jambos) in Costa Rica (Avalos et al., 2006).
Chemical Control
Syzygium species can be controlled by herbicides, and in places where species have become serious threats to native flora, a combination of physical and chemical control methods have been reported. Syzygium cumini, for example, forms a dense cover and because of its extensive cultivation as a fruit tree, has become very invasive in Hawaii, the Cook Islands, and French Polynesia; vigorous efforts are being undertaken in Hawaii to remove the species through chemical control. Syzygium jambos is likewise an invasive species on several Pacific islands, and has been reportedly controlled by applying herbicides.
