NMDA recognizes that a small number of residential pecan trees are being affected by pecan weevil. This is occurring in five eastern New Mexico cities. Pecan weevil is a significant insect pest of pecan. It is not recognized as being established in New Mexico commercial orchards.

NMDA and NMSU’s Cooperative Extension Service recognize the economic importance of the pecan industry. It is important to the region and the negative impact that pecan weevil will have on the industry. Over the past 10 years, both organizations have cooperated on annual surveys and outreach programs. This is part of an early detection and eradication approach to prevent pecan weevil establishment in the western region.

Recently pecan weevil has been identified in residential trees in Clovis, Roswell, and Lovington. Additional pecan trees were identified with pecan weevil in Artesia and Hobbs.

As a result of the recent pecan weevil findings, NMDA has extended the original sixty-day quarantine. It added an additional 90 days. Limit the spread of pecan weevil from infested residential trees to commercial orchards. Movement of pecans produced within the city limits of Clovis, Roswell, Hobbs, Artesia, and Lovington is restricted. This restriction requires a certificate from NMDA stating specific pecans meet one or more of the following requirements.

  • Pecans that are sold, traded or gifted in a manner that meet the phytosanitary requirements of the receiving location. They must also be transported in a department approved manner.
  • Pecans treated at 0 degrees for 168 continuous hours, or other department approved treatment methods;
  • The inspection of a pecan sample where no pecans exhibit signs of the pecan weevil or weevil presence.
  • Pecans originating in the quarantined area but believed, by the department, not to have the presence of pecan weevil.

Specifics regarding the certification of pecan nuts can be found within the quarantine rule at http://www.nmda.nmsu.edu/wp-content/uploads/2017/03/21.17.36-NMAC-3.27.2017-AMENDED.pdf. Information is also available at the affected area’s County Cooperative Extension Offices.  Residential and commercial pecan tree owners should be on the lookout. Look for pecans with round, BB-sized holes in the shells, or legless, white grubs inside the pecan nut.
