IPM in New Mexico Pecan Production

  This site is currently under construction.  The degree-day model for the pecan nut casebearer 2000 growing season can be found in Current Information. 

     New Mexico is one of four states that contribute to western pecan production.  Within New Mexico, pecan production is concentrated in Pecos and Mesilla Valley regions located in the southern edged of the state.  New Mexico pecans are primarily flood irrigated and comprised of improved varieties, mainly Western Schley.  The exclusive use of improved varieties has resulted in consistent above average yields (national).  There are approximately 30,000 acres of pecans in New Mexico with an annual average production level of 40-50 million pounds of nuts. 

    Currently, widespread primary economic insect pests are limited to two aphid species (black pecan aphid, blackmargined aphid) and one lepidopterian pest (pecan nut casebearer).  Occasional insect pests include the walnut caterpillar, fall webworm, stink bug, hickory shuckworm and termites.  The arid climate helps limit pathogen pests to primarily sooty mold during humid years.  New potential pest problems in western pecans include pecan weevil and nematodes.  Identification, biology and control for each pest species is included in the links.
