					CORN TESTING – DIFFERENT VERSIONS OF THE
          SAME HYBRID –
      HOW DO WE HANDLE THIS?

TRANS-GENES
§ Agrisure®GT – provides tolerance to in-crop applications of glyphosate-
  based herbicides
§ Agrisure®GT/CB/LL – provides control against ECBas wella s other insects
  and is tolerant to glyphosate and glufosinate herbicides
§ Agrisure®3000GT – protects against ECB, CE, WR, NR, MR; suppresses FA,
  CSB/tolearnt to glyphosate and glufosinate herbicides
§ Agrisure Viptera™ 3111 – protects against ECB, SWCB, SCB, WBC, BC, FA,
  CE/ tolerant to glyphosate and glufosinate herbicides
§ Herculex I (HX1) – SWB, ECB, SCB, WBC, BC,FA/tolearnt to glufosinate
  herbicide
§ YHR – pyramid of HX1 and YieldGard corn borer

§ Note: There are several species of corn rootworm in the Southeast.
  Southern corn rootworm is the most prevalent species. None of the
  above “rootworm” products are not effective against southern corn
  rootworm.
SEED TREATMENTS

§ Cruiser Extreme 250
  § Cruiser (thiamethoxam) @ 0.25 mg ai/seed
  § Three fungicides: Apron XL®, Maxim® XL,
    Dynasty®
§ Cruiser 1250
  § Cruiser (thiamethoxam) @ 1.25 mg ai/seed
  § Three fungicides: Apron XL®, Maxim® XL,
    Dynasty®
SEED TREATMENTS
§ Poncho/Votivo
  § Insecticide and a new biological mode of action
    with a unique bacteria strain that lives and grows
    with young roots, creating a living barrier strain that
    prevents important nematode species from
    reaching the roots
§ Acceleron
  § Fungicides: Ipconazole (Vortex), Metalaxyl (Apron XL,
    Ridomil), Trifloxystrobin (Stratego, Compass)
  § Insecticide: Clothianidin (Poncho 250)

CORN TESTING – DIFFERENT
VERSIONS OF THE SAME HYBRID




DARYL BOWMAN
WATCH FOR VARIATIONS IN CORN HYBRIDS

TOM BECHMAN
AUGUST 14, 2007
FARM FUTURES
60 CORN HYBRIDS
PARENT AND 2 VERSIONS
ONLY A FEW VERSIONS WERE NOT THE SAME
 AS PARENTS
 MAJOR GOODMAN - NCSU
I see no harm in combining/subbing RR versions
 with non-RR versions. I'd be hesitant to do the same
 for bt or LL versions. I see no harm - even some good
 - in head-to-head testing of conventional vs GMO vs
 stacks in the same trials. The data might save some
 farmers $$$$ as there is apt to be little difference in
 some locations and the rootworm bts (and some cb
 bts as well) may actually come at a yield cost. I
 doubt that most of your corn tests are accurate
 enough to detect such differences, as they tend to
 be small and our errors (relative to the Midwest) are
 large/huge.
DENNIS MCCOY - PIONEER

1) One version of a hybrid should be entered.

 2) Second version should be considered the
 same as previous year because the base
 genetics are the same.
MIKE BAKER – MONSANTO
 Have no good solution…..sometimes version changes
  have an anticipated effect on performance, sometime
  they won’t, so not sure you can make a hard and fast
  rule…..simplest and cleanest is probably to accept each
  version as a different product and not combine for multi-
  location or multi-year summaries.
 
 The version changes probably won’t slow down….I’m
  know that we, and I’m sure others,  have a pipeline that
  will continue to launch new traits in all crops.
