AM1—Optimum® AcreMax® 1 Insect Protection System with an integrated corn rootworm refuge solution includes HXX, LL, RR2. Optimum AcreMax 1 products contain the LibertyLink® gene and can be sprayed with Liberty® herbicide. The required corn borer refuge can be planted up to half a mile away. AM—Optimum® AcreMax® Insect Protection system with YGCB, HX1, LL, RR2. Contains a single-bag integrated refuge solution for above-ground insects. In EPA-designated cotton growing counties, a 20% separate corn borer refuge must be planted with Optimum AcreMax products. AMX—Optimum® AcreMax® Xtra Insect Protection system with YGCB, HXX, LL, RR2. Contains a single-bag integrated refuge solution for above- and below-ground insects. In EPA-designated cotton growing counties, a 20% separate corn borer refuge must be planted with Optimum AcreMax Xtra products.
YGCB-The YieldGard® Corn Borer gene offers a high level of resistance to European corn borer, southwestern corn borer and southern cornstalk borer; moderate resistance to corn earworm and common stalk borer; and above average resistance to fall armyworm. RR2-Contains the Roundup Ready® Corn 2 trait that provides crop safety for over-the-top applications of labeled glyphosate herbicides when applied according to label directions.
HX1-Contains the Herculex® I Insect Protection gene which provides protection against European corn borer, southwestern corn borer, black cutworm, fall armyworm, western bean cutworm, lesser corn stalk borer, southern corn stalk borer, and sugarcane borer; and suppresses corn earworm. HXX-Herculex® XTRA contains the Herculex I and Herculex RW genes.
LL-Contains the LibertyLink® gene for resistance to Liberty® herbicide.

The 2013 rollercoaster growing season continues with harvest well underway. September and early October brought much needed mild weather and above average temperatures. Entering the third week of August GDU accumulation was tracking 140 GDUs under the 10 year average. At that point, there was serious concern if the corn crop would be able to reach black layer prior to a major frost. As a result of the mild fall, a majority of fields have reached black layer and SE Minnesota has yet to have a killing frost. Yield results have been mixed based on geography and weather. We cannot forget about the spring we had when we evaluate yield data for 2013. Planting dates ranged from late April to early July in some areas; planting conditions during that timeframe were challenging at best.
Rollercoaster Ride Continues
November 2013 - Issue 6
Analyzing 2013 Yield Data
Planting date: In many instances plots were planted much later than normal without making changes to the maturity of the products. Earlier corn and soy-bean products have done extremely well compared to standard of full season products.
Corn Flowering date: Late flowering hybrids have tended to struggle in plots due to late planting dates and heat and moisture stress that occurred the sec-ond half of August as these hybrids were flowering.
Multiple Locations: Try to seek out plots that were replicated in the surrounding area. This will show some of the variables and give you a solid picture of how products performed in your area.
Multiple Years: It will be important to seek out 2012 yield data as well before decisions are made for next year. Products that shined in 2012 may not look nearly as good in 2013 based on planting and flower-ing date. Evaluate both years closely before making final product decisions for 2014.

1 All Pioneer products are hybrids unless designated with AM1, AM, AMRW, AMX, and AMXT, in which case they are brands. 2012-2013 data collected through October 25, 2013. Data for individual product/variety comparisons was from the following geographic selection: Minnesota, Wisconsin & Northern Iowa. Infor-mation and results contained herein represent the average of all comparisons. Comparisons may be against any number of competitors unless otherwise indicated. Multi-year and multi-location information is a better predictor of future performance. Product/variety responses are variable and subject to any number of environmental, disease, and pest pressures. +/- 5 CRM. DO NOT USE THIS OR ANY OTHER DATA FROM A LIMITED NUMBER OF TRIALS AS A SIGNIFICANT FACTOR IN PRODUCT SELECTION.
