    Three Reasons to Find Stine at a Trade Show Near You

    January 30, 2019

    Posted by Todd Schomburg in Stine News

    Winter trade show season is upon us! The Iowa Power Farming Show is underway this week in Des Moines, and we’ve got a lot of great information to share with growers. The Iowa Power Farming Show is the third largest indoor ag show in the United States, spanning more than seven acres with over 1,932 booths and 750 companies exhibiting at the event. You can find Stine at booth #1044 on the main level of the Community Choice Convention Center, right next to the escalator. We’re excited to hear from growers at the show about their 2019 planting plans and how Stine can fit into their operations. Here are the top three topics we look forward to discussing at trade shows this winter.

    1. Movement on the Enlist E3 This week, MS Technologies — one of the developers of the Enlist E3 soybean trait — announced plans for full-scale launch of the product. The company notes, “Once all regulatory approvals have been received, Enlist E3 soybeans will be offered in the United States and in Brazil and Canada. Growers can expect commercial sales of the soybeans to begin in 2019, with a much broader, full-scale launch in 2020.” Enlist E3 soybeans offer growers an advanced herbicide-tolerant trait technology with maximum flexibility and convenience, along with the ability to use three unique modes of action for exceptional weed control. We have 37 Stine® Enlist E3 soybean options for growers in 2019, ranging from an 0.0/0.1 maturity to a 5.0. The trait is still awaiting import approval from the Philippines.
    2. LibertyLink® GT27 platform ready to be put to the test. Seed sales have skyrocketed for Stine LibertyLink GT27 brand soybeans this year. LibertyLink GT27 soybeans are the first commercially available soybean trait package that offers growers built-in tolerance to glyphosate, glufosinate and a new HPPD/Group 27 herbicide for soybeans, exhibiting powerful performance over tough weeds. Stine is pleased to offer growers the industry’s broadest lineup of LibertyLink GT27 brand soybeans in 2019, with 44 options ranging from an 0.3 maturity to a 4.4. We look forward to seeing these soybeans in the field this year and hearing success stories throughout our sales territories.
    3. Seed production partners wanted. With powerful new soybean traits like Enlist E3 and LibertyLink GT27 entering the market, we need more seed production acres to accommodate increased demand for the soybean technologies. Growers who would like to get involved as a Stine seed production partner can benefit from having priority access to the newest, highest-yielding soybean genetics as they become available, and, in some cases, numbers that are not yet commercially available or are otherwise sold out. Stine seed production partners also receive agronomic support from our reputable team of agronomists and sales experts to help implement best management practices that enhance the performance of the new trait technologies.

    If you’re unable to join us at the Iowa Power Farming Show this week or at another trade show this winter, please contact your local Stine sales representative. Not sure who to contact?

    Maximizing Effectiveness of LibertyLink® GT27™ Technology with Glyphosate and Glufosinate

    January 23, 2019

    Posted by Stine Seed in Products

    Maximizing Effectiveness of LibertyLink® GT27™ Technology with Glyphosate and Glufosinate

    If seed sales are any indication, growers are ready for LibertyLink® GT27™ brand soybeans this planting season. This exciting new technology 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 outstanding weed control and unparalleled flexibility in weed management options. That being said, when growers ask us about the product, their main concern tends to be if they can spray both glyphosate (Round-Up®) and glufosinate (Liberty®) on the beans at the same time. The short answer is yes. But there are a few more complexities to consider before you tank mix. 

    Before combining the two chemistries in tank mixes, it’s important to observe the following recommendations. 

    • Glyphosate, a Group 9 herbicide, tends to work slowly, approximately 7–14 days, and is recommended to be sprayed with coarse to large-sized droplets in 5–10 gallons of water per acre. It is a systemic, translocating herbicide that inhibits the EPSP synthase pathway and blocks essential amino acids that are necessary for the photosynthetic processes of the plant.
    • Glufosinate, a Group 10 herbicide, tends to work very quickly, within 24–72 hours, and is recommended to be sprayed with medium to coarse sized droplets in 15–20 gallons of water per acre. It is a contact, semi-translocating herbicide that inhibits glutamine synthetase. It mainly kills by inhibiting a plant’s ability to utilize nitrogen and causing ammonia within the plant to become toxic to the plant.
    • It is best to utilize these products in a sequential-combined application. Use glyphosate in burndown combinations with other effective modes of action and residual herbicides. For post-emergent applications, combine glyphosate and glufosinate with additional effective modes of action and residual herbicides. This provides the best chance of overcoming nature’s ability to adapt and combat herbicide resistance.
    • For optimum weed control and long-term effectiveness of the trait system, it is recommended to utilize three effective site-of-action herbicides per application with one of those being a soil-applied residual herbicide.
    • Always utilize the “most restrictive” label for guidelines. In this case, that would be glufosinate (Liberty).
    • Spray volume should be applied in the 15–20 gallons per acre window.
    • 5–3 pounds of ammonium sulfate should be used per acre.
    • Target medium to coarse droplets. A good rule of thumb is volume per acre plus pressure should equal 60. For example, if you are spraying 15 gallons, then pressure should equal 45 psi.
    • DO NOT use the addition of non-ionic surfactants.
    • DO NOT apply during periods of heavy dew or fog. If relative humidity is low, increase droplet size to coarse droplets to counteract evaporative loss. DO NOT apply after two hours before sunset.
    • Anti-foam agents may help prevent excessive foaming.
    • DO NOT apply after R1 growth stage.
    • Rainfast = 4 hours

    NOTE: Growers should always read and follow all herbicide label directions and adhere to both federal and state regulations for applications. For questions about usage recommendations and restrictions, please contact a certified herbicide applicator or an extension weed specialist.

    Optimize ROI and Yield with Stine® Conventional Corn

    January 16, 2019

    Posted by Stine Seed in Products

    Each year, growers browse through pages upon pages of seed catalogs looking for the right corn hybrids that will hopefully maximize per acre profits. At Stine, we have a significant number of conventional, non-traited corn hybrids that can help growers increase their bottom line without sacrificing performance. We are one of the only seed companies that actively develops new conventional genetics. In fact, conventional genetics are the base of our breeding program, which means many times material that advances from our Elite Yield Trials — the last phase of our breeding program — to commercial release is often first released in conventional form.

    Other seed companies are often bound to a specific line of insect- or herbicide-tolerant traits; however, as an independent seed company, Stine has the flexibility to work with conventional material first and then add traits from any trait provider later, no strings attached. Because not every situation calls for traits, many growers have found value in our elite conventional corn. This is especially true as we’re seeing fewer issues with above- and below-ground pests. More and more growers are reverting back to conventional corn or corn that only includes herbicide tolerant traits. This allows growers to save on trait fees and use a traditional insecticide for any insect pressure that does pop up.

    Stine has a unique lineup of conventional corn, ranging from 77-day to 120-day relative maturity. For more information about Stine conventional corn, please contact your local Stine sales representative.
