IMPORTANT: Trait rating scores provide key information useful in selection and management of Brevant® brand products in your area. Information and ratings are based on comparisons with other Brevant brand products, not competitive products. Information and scores are assigned by Corteva Research Managers. Scores are based on period-of-years testing through 2022 harvest and were the latest available at time of printing. Some scores may change after 2023 harvest. Scores represent an average of performance data across areas of adaptation, multiple growing conditions, and a wide range of both climate and soil types, and may not predict future results. Individual product responses are variable and subject to a variety of environmental, disease and pest pressures. Please use this information as only one component of your product positioning decision. Refer to www.brevant.ca or contact your local sales representative for the latest and most complete listing of traits and scores for each Brevant brand product.
1 TECHNOLOGY SEGMENT
Enlist Duo® and Enlist™ 1 are the only 2,4-D products authorized for use with Enlist™ crops. Consult Enlist herbicide labels for weed species controlled. Always read and follow label directions.
ALWAYS READ AND FOLLOW PESTICIDE LABEL DIRECTIONS. Roundup Ready® technology contains genes that confer tolerance to glyphosate, an active ingredient in Roundup® brand agricultural herbicides. Agricultural herbicides containing glyphosate will kill crops that are not tolerant to glyphosate.
Corteva Agriscience is a member of Excellence Through Stewardship® (ETS). Corteva Agriscience products are commercialized in accordance with ETS Product Launch Stewardship Guidance and in compliance with the Corteva Agriscience policies regarding stewardship of those products. In line with these guidelines, our product launch process for responsible launches of new products includes a longstanding process to evaluate export market information, value chain consultations, and regulatory functionality. Growers and end-users must take all steps within their control to follow appropriate stewardship requirements and confirm their buyer’s acceptance of the grain or other material being purchased.

2 RELATIVE MATURITY: Shows the relative maturity group rating, with the first one or two digits representing the general maturity group, and the last digit showing relative maturity within the group on a scale of 0 to 9, with 0 early and 9 late. For example, a soybean product with a relative maturity rating of 008 would be a late product in Group 00 maturity.
3 FIELD EMERGENCE: Rating based on speed and strength of emergence in sub-optimal temperatures.
1-3 = Below Average; 4-6 = Average; 7-9 = Excellent.
4 PHYTOPHTHORA RESISTANCE GENE:
(-) = No specific gene for resistance.
Rps1^^ = Contains Rps1c or Rps1k Phytophthora resistance.
Rps 1a = Provides resistance to races 1, 2, 10, 11, 13-18, 24, 26, 27, 31, 32 & 36.
Rps 1c = Provides resistance to races 1-3, 6-11, 13, 15, 17, 21, 23, 24, 26, 28-30, 32, 34, 36.
Rps 1k = Provides resistance to races 1-11, 13-15, 17, 18, 21-24, 26, 36, 37.
Rps 6 = Provides resistance to races 1-4, 10, 12, 14-16, 18-21, 25, 28, 33-35.
Rps 3a = Resistant to races 1-5, 8-9, 11, 13-14, 16, 18, 23, 25, 28-29, 31-35, 39-41, 43-45, 47-52, 54
Rps 3c = Resistant to races 1-4, 10-16, 18-36, 38-54
5 PHYTOPHTHORA FIELD TOLERANCE: Products with high tolerance scores have demonstrated an ability to thrive in the presence of Phytophthora races to which they lack specific resistance. In some products, tolerance is expressed only after the early seedling growth stage, making such products susceptible to damping off during emergence and early seed growth.
6 WHITE MOULD: Scores based on Brevant research observations of comparative white mould tolerance among various soybean products across multiple locations and years. All products are capable of developing white mould symptoms under severe infestations. To our knowledge, there are no totally resistant products in the industry. However, differences exist in the ability of products to tolerate white mould (i.e., the rate at which the infection develops and the extent of damage it causes). These scores reflect those differences.
7 SCN RESISTANCE SOURCE: There are three sources of genetic resistance to SCN currently deployed in the marketplace: PI88788; PI548402 (also known as Peking).
8 CANOPY WIDTH: 9 = Extremely bushy; 1 = Very narrow.
9 PLANT HEIGHT FOR MATURITY: 9 = Tall; 1 = Short.
10 HILA COLOR: BL = Black; BR = Brown; TN = Tan; G = Gray; IB = Imperfect black; BF = Buff; Y = Yellow (Clear); M = Mixed.
