    Superior Genetics, Maximum Yields: Stine® GT27™ and LibertyLink® GT27™ Brand Soybeans

    June 27, 2018

    Posted by Stine Seed in Products

    Stine is uniquely positioned to provide the latest innovative products on the market, giving growers new choices for weed management, including our lineup of Stine® GT27 and LibertyLink® GT27 soybeans. Combined with the high-yielding, elite genetics and the industry’s most sought after traits for weed control, Stine GT27 and LibertyLink GT27 offer growers powerful performance and outstanding crop safety.

    Stine GT27
    Stine GT27 soybeans are derived from the high-yielding, elite soybean genetics that provide the yields growers have come to expect from Stine. In fact, Stine GT27 soybeans have demonstrated performance equal to or better than many of the varieties that growers currently plant.

    The Stine GT27 platform builds upon current glyphosate-based programs with the option to utilize a new HPPD/Group 27 herbicide (once approved) for the benefit of two sites of herbicide action. This combination will allow growers to combat a full spectrum of broadleaf weeds and grasses, including glyphosate-, triazine-, PPO- and ALS-resistant weeds. Both of the herbicide components are non-volatile chemistries, reducing the risk for off-target movement and giving growers additional peace of mind.

    LibertyLink GT27
    Stine LibertyLink GT27 soybeans are the next evolution of the GT27 platform. A triple-stacked herbicide trait, Stine LibertyLink GT27 brand soybeans offer exceptional yield potential combined with tolerance to three unique sites of action — glyphosate, Liberty® and a new HPPD/Group 27 herbicide for soybeans.

    The LibertyLink GT27 trait is the first commercially available soybean trait package that offers built-in tolerance to both glyphosate and glufosinate, which means that growers who plant Stine LibertyLink GT27 soybeans will benefit from unparalleled flexibility in weed management options. This triple-stacked technology offers growers the option to use multiple pre- and post-options, plus built-in residual control, for full-season control across different growing environments.

    Stine is pleased to offer a complete lineup of Stine GT27 and LibertyLink GT27 in a range of maturities. To learn more about our lineup, reach out to your local Stine sales representative.

    Note: One characteristic of HPPD/Group 27 chemistries is they provide outstanding residual control, meaning that the active ingredients remain active in the soil for a period of time after application. However, the amount of HPPD/Group 27 chemistry that remains active in the soil into the next growing season can vary, and in some cases could affect soybeans that are susceptible to the HPPD/Group 27 chemistry. Stine GT27 and LibertyLink GT27 soybeans include built-in tolerance to HPPD/Group 27-based herbicides, providing soybean growers with an additional measure of protection against HPPD-Group 27 carryover.

    How to Identify and Manage Sudden Death Syndrome in Soybeans

    June 21, 2018

    Posted by Darrin Petty in Crop Management

    Sudden Death Syndrome (SDS) is a disease that growers may encounter in soybean fields this summer. It typically appears in the mid- to late-pod-filling stages. SDS is caused by a fungus (Fusarium) in the soil, which is usually brought about by cool, wet weather and/or soil compaction.

    SDS can be confused with Brown Stem Rot (BSR) because they have similar foliar symptoms. But, at the end of the day, both can result in damaging yield losses. This is why it’s important to properly diagnose the disease as either SDS or BSR to ensure you’re implementing the correct disease management practices.

    According to Iowa State University Extension and Outreach, the best way to differentiate SDS from BSR is to split the stems and examine the pith for internal browning. If it’s BSR, the pith may have browning; if it’s SDS, the pith will be white. You will also want to study the root of the plant. In SDS, root rot can occur, and the root can also produce blue spores from the fungus.

    If SDS is present in your fields this year, there are some strategies you can implement next year to help keep the disease at bay. While you can’t avoid the weather, I recommend avoiding compaction. I also recommend planting a bit later if cool, wet weather is an issue. If your field is prone to water logging, I also recommend installing an effective drainage system. Choosing a variety with SDS tolerance and using seed treatments should also be a priority.

    Stine XP Soybean Seed Treatments are ideal for helping combat SDS. The seed treatments offer growing protection from early seedling diseases like SDS that threaten your bottom line. Stine XP treatments protect the soybean seed during its most vulnerable time, encouraging good early vigor and helping ward off the early onset of insects and disease.

    Agrisure® Corn Advantages

    June 13, 2018

    Posted by Stine Seed in Products

    Stine’s line of corn containing Agrisure® traits continues to be prominent in our lineup. Over the past few years, we’ve seen great yields and outstanding performance from a number of Stine® Agrisure lines.

    Following are some of the competitive features and benefits of Stine Agrisure brand corn:  

    1. High-yielding genetics. The entire lineup of Stine Agrisure brand corn is based on high-yielding, elite genetics that provide the kind of yields that growers have come to expect from Stine.
    2. Herbicide flexibility. Agrisure Viptera®, Agrisure 3010 and Agrisure GT/CB/LL products provide growers with great herbicide flexibility with tolerance to both glyphosate and glufosinate. Any of the E-Z Refuge® lines are glyphosate tolerant only.
    3. Season-long insect control. Several Agrisure traits boast either above- and/or below-ground insect protection, tackling pests such as the European corn borer, southwestern corn borer, southwestern cornstalk borer, corn earworm, fall armyworm, dingy cutworm, beet armyworm and black cutworm.
    4. Rootworm protection. Stine Agrisure Duracade® brand corn is an excellent option for growers that regularly experience heavy rootworm pressure. The Agrisure Duracade trait expresses a protein that binds differently in the gut of corn rootworm compared to other corn rootworm products on the market, providing superior control against Western, Northern and Mexican corn rootworm, which in turn allows the plant to develop a stronger root system. NOTE: Agrisure Duracade is not yet fully approved in all export markets and must be channeled.*
    5. Refuge options. Some Agrisure corn traits come pre-packaged with structured refuge right in the bag. Stine Agrisure 3120 E-Z Refuge and Agrisure Viptera 3220 E-Z Refuge offer growers high-yielding genetics and outstanding insect control with the added convenience of refuge in bag. Both brands contain five percent integrated refuge in bag, suitable for corn-growing areas (additional 20 percent structured refuge required in cotton-growing areas). However, please consult the 2018 Syngenta Stewardship Guide for refuge requirements.
    6. Drought tolerance. Agrisure Viptera 3110A provides the same season-long insect control as Agrisure Viptera3110, but with the added protection of Agrisure Artesian™ for superior drought tolerance. Stine Agrisure Artesian brand corn utilizes Agrisure Artesian’s water optimization technology for additional protection from moisture stress. 

    To learn more about Stine’s corn lineup including Agrisure brand traits, visit our website or reach out to your local Stine sales representative.

    * The Agrisure Duracade trait is approved for sale in the United States and Canada, and for export to most international markets, but it is not fully approved worldwide. Growers purchasing corn containing the Agrisure Duracade trait must sign an Agrisure Duracade Grain Use Agreement at the time of seed purchase to verify they will deliver the resulting grain to an accepting location or utilize it for livestock feeding. To learn more about specific locations accepting Duracade, contact Gavilon Grain at (844) 559-1500.
