Since 2007, APHIS and state plant regulatory officials have taken action to eradicate gladiolus rust, caused by Uromyces transversalis, whenever the pathogen was detected in the United States. Despite consistent and coordinated efforts to eradicate this pathogen, U. transversalis is established and has spread to the limit of its natural range in the United States.
Effective May 2015, APHIS will no longer take action, nor will we require state partners and industry to take action, when the pathogen U. transversalis is found in commercial growing areas, domestic commerce, or in residential areas. By making these changes, APHIS and state plant regulatory officials will be able to focus resources on other, more serious pests. These changes will also allow APHIS to remove burdensome requirements from growers and homeowners who were often forced to destroy infected plants. APHIS will continue to serve as a technical resource and will cooperate with other USDA agencies, state departments of agriculture, and the gladiolus industry to develop best management practices to control U. transversalis.
APHIS has initiated rulemaking to update import requirements for gladiolus and other host plants to no longer require action at ports of entry when the pathogen U. transversalis is found in arriving shipments. Once rulemaking is complete, APHIS will no longer require action at ports of entry when the pathogen U. transversalis is found in arriving shipments. APHIS will notify trading partners when the import regulations are final.
APHIS will continue to regulate other gladiolus rust pathogens that are not known to occur in the United States, including Puccinia gladioli, Puccinia mccleanii, Uredo gladioli-buettneri, Uromyces gladioli, and Uromyces nyikensis.
