SAGARPA Publishes HLB Phytosanitary Control Areas
Policy and Program Announcements
The Secretariat of Agriculture published in the Diario Oficial, on October 31, 2012, an announcement
that specifies the zones under phytosanitary control due to the presence of Huanglongbing, a serious
Introduction: This report summarizes an announcement by the Secretariat of Agriculture (SAGARPA)
published in Mexico’s “Diario Oficial” (Federal Register) on October 31, 2012, that specifies the zones
under phytosanitary control due to the presence of Huanglongbing (Candidatus Liberibacter spp), also
known as HLB or citrus greening. HLB is considered to be one of the most serious citrus diseases in the
world. It is a bacterial disease that spreads internally throughout the plant. The bacteria do not pose a
health threat to humans, livestock or pets. The disease is transmitted from infected plants to healthy
plants by the Asian citrus psyllid or the grafting of infected tissues onto healthy host plants. Symptoms
commonly associated with the disease first appear as yellow shoots or blotchy mottling and/or
yellowing of the leaves. As the disease progresses, the trees suffer excessive leaf drop and foliage
becomes sparse with fewer or smaller leaves and tip dieback. The disease also affects the fruit, causing
it to ripen unevenly and become lopsided, visibly smaller and bitter-tasting. Seeds within the fruit fail
to fully develop and are aborted. Once the host plant becomes infected, there is no cure for the disease.
Disclaimer: This summary is based on a cursory review of the subject announcement and therefore
should not, under any circumstances, be viewed as a definitive reading of the regulation in question, or
of its implications for U.S. agricultural export trade interests. In the event of a discrepancy or
discrepancies between this summary and the complete regulation or announcement as published in
Spanish, the latter shall prevail.
Title: Announcement that specifies the zones under phytosanitary control due to presence of
Huanglongbing (Candidatus Liberibacter spp).
In accordance to article six of the Agreement to announce the phytosanitary measures that will apply for
the control of Huanglongbing (HLB) and its vector published on August 16, 2010 (See Report MX
0055), the states where SAGARPA detects the presence of HLB will be considered Zones Under
Phytosanitary Control and will be publicized through an announcement in the Diario Oficial.
Therefore, due to information from the National Center for Phytosanitary Reference, SAGARPA
officially announced that HLB has been detected in several states. Consequently, the following states
are included as zones under phytosanitary control: Quintana Roo, Yucatan, Nayarit, Jalisco, Colima,
Campeche, Sinaloa, Michoacan, Chiapas, Baja California and Hidalgo.
SAGARPA, through its General Directorate of Plant Health (section of SENASICA), carries
information of the status of HLB in Mexico on its web page where they have an overview of activities
that are being carried out, information on documents for legal measures, current phytosanitary situation,
and other topics. USDA Animal and Plant Health Inspection Service (APHIS) also manages a web page
that contains information on the HLB situation in the U.S.
