Rating Scale

1 = Excellent; 9 = Poor, — = None

A rating of "1" in standability is a corn product with excellent standability. A rating of "1" in brown stem rot is a product with excellent tolerance to brown stem rot. For white mold and Phytophthora Field Tolerance, see specific rating scales on this page. 

Codes

L = Low; S = Short; M-S = Medium-Short; M = Medium; M-MH = Medium-Medium High; M-H = Medium-High; M-L = Medium-Low; M-T = Medium-Tall; MH-H = Medium High-High; T = Tall; H = High; NDFd = Neutral Detergent Fiber digestibility

Traits

CONV = Conventional; RR2 = Roundup Ready® Corn 2; SS = SmartStax® Corn; SSRIB = SmartStax® RIB Complete® corn blend; VT2P = VT Double PRO® corn; VT2PRIB = VT Double PRO® RIB Complete® corn blend; VT3P = VT Triple PRO® corn; VT3PRIB = VT Triple PRO® RIB Complete® corn blend; DGVT2P = DroughtGard® Hybrids with VT Double PRO® corn; DGVT2PRIB = DroughGard® Hybrids with VT Double PRO® RIB Complete® corn blend; DGVT3PRIB = DroughtGard® Hybrids with VT Triple PRO® RIB Complete® corn blend; WX = Waxy; W = White

Rating Scale

These ratings are appropriate and should not be considered as absolute. Based on Bayer conducted trials relative to other DEKALB® brand corn.

Herbicide Tolerance

Ratings are based on observations and research using herbicide at labeled and above labeled rates to simulate extreme environmental conditions, misapplication and adverse soil pH or organic content. 

A = Acceptable

Either no adverse effects from the corn product/herbicide combination were noted on any traits or only slight damage could be noted under adverse conditions or herbicide application at higher than label rates.

C = Caution

The corn product/herbicide combination is usually not a problem if sprayed according to label directions, but can result in plant height reductions, stand loss and suspected yield loss under very adverse environmental conditions, high rates or extreme soil pH levels or organic content. Use drop nozzle spraying for postemergence herbicides to avoid interactions.

W = Warning

Not advised — this corn product/herbicide combination should not be used under any circumstances.

GDU (Growing Degree Unit)

Although maturity of one corn product relative to another remains reasonably constant, the actual number of calendar days from planting to any given point of plant development varies with temperature, day length, rate and date of planting, soil fertility and other environmental factors. All GDU values calculated are from the time of planting.
