More rootworm protection data coming this fall

Agriculture.com Staff 08/09/2006 @ 12:25pm

Research conducted across the Corn Belt in 2006 by Pioneer Hi-Bred International, Inc., shows that corn hybrids with the Herculex RW Rootworm Protection and Herculex XTRA traits provide excellent protection against corn rootworm.

"Based on the thousands of roots we evaluated, it's clear that those with Herculex RW or Herculex XTRA provide industry-leading protection against corn rootworm damage, a problem that more and more growers are facing," said Murt McLeod, Pioneer research scientist.

Root digs were conducted among 15 different sites throughout the Corn Belt, evaluating a broad range of corn rootworm management technologies, such as in-plant biotech traits, insecticide seed treatments and traditional granular insecticides. All were compared to unprotected checks.

The studies, which also showed that hybrids with the Herculex RW and Herculex XTRA traits provided good standability in environments where untreated checks had significant early root lodging, were conducted by Pioneer agronomists. Additional root digs are being done by land grant university entomologists this season and will be released later this year.

A second round of root evaluations will take place later in the season to confirm the season-long protection from Herculex RW and Herculex XTRA technologies. Harvest and yield data will also be collected in the fall.
