Pecan Orchard Workshop to Focus on Insect Control

LAS CRUCES -- The pecan nut casebearer will be the focus of the Insect Control in Pecan Orchards Workshop May 18 at the Leyendecker Plant Science Center, south of Las Cruces.


The pecan nut casebearer was found in the El Paso, Texas area about 10 years ago, said Esteban Herrera, horticulture specialist with New Mexico State University's Cooperative Extension Service . The insect had been present in eastern New Mexico, but had not shown up in the Mesilla Valley and El Paso area before 1988.

"Once we found it in El Paso, we knew that it was just a matter of time before it came this way," Herrera said. "For the last two years, growers in southern Doņa Ana County have been spraying to control the pecan nut casebearer and prevent any damage."

The workshop, which is being sponsored by Extension and Helena Chemicals of Mesquite, will begin at 9 a.m. It also will cover some beneficial insects and other pest problems occurring in pecan orchards.

"Last year, the pecan weevil was found in the Tularosa Basin near Alamogordo," he said. "Oddly enough, this same pest was found 30 years ago in the same area. But spreading was controlled with recommended practices made by NMSU's Cooperative Extension Service and a quarantine put into effect by the New Mexico Department of Agriculture."

Herrera said the workshop will give growers an update on government regulations related to controlling pecan weevils. "By letting them know what's going on with this insect, they'll get the right information and won't panic."

In the afternoon, producers will have a chance to visit pecan orchards for a first-hand look at some problems they may encounter, Herrera said.

There is no cost for the workshop. A free lunch, sponsored by several companies, will be served. For more information and to register for lunch, call NMSU's Cooperative Extension Service at (505) 646-1715 or Helena Chemicals at (505) 233-3171.
