    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.

    Scout for Japanese Beetles

    June 06, 2018

    Posted by Tony Pleggenkuhle in Crop Management

    Between June and July, growers may notice small beetles with shiny copper-colored bodies and green heads popping up in their corn and soybean fields. These little nuisances are Japanese beetles — a pest that became an issue for growers last year and could potentially affect yields this year if not properly managed. 

    Japanese beetles emerge from hibernation as grubs in the spring as temperatures rise and then pupate into adults within four to six weeks after. Unfortunately, they do not travel alone. Where there’s one Japanese beetle, much more are likely nearby. When they feed, they emit a pheromone that attracts hordes of other beetles.

    According to the Iowa State University Department of Extension and Outreach, Japanese beetles host on more than 300 plants. In soybeans, the beetles feed on and skeletonize the leaves. In corn, they can be even more damaging if they clip silks during pollination, which could affect grain fill and yield. Iowa State University recommends that treatment in soybeans should be considered if 30 percent of the leaf is skeletonized before bloom and 20 percent defoliation after bloom. For corn, foliar insecticide should be considered at tasseling and silking if three or more beetles can be found per ear, if the beetles have clipped less than a half inch of the silks and if pollination has not yet reached 50 percent complete.

    I recommend to spray a Lorsban-type insecticide over the canopy if you have a high enough level of silk clipping in corn. This tactic will help you achieve good penetration and control over the beetles. I recommend the same treatment for soybeans if leaf defoliation is present before bloom and pod fill, and even after bloom. Because Japanese beetles can survive in your soil through the winter, get ahead of them this year to prevent them from coming back in the coming years.

    To learn more about signs of Japanese beetles and how to protect your fields, contact your local Stine representative.

    Crop Progress Report

    May 30, 2018

    Posted by Stine Seed in Planting

    The USDA’s National Agricultural Statistics Service (NASS) released their latest crop progress report on May 29. The survey represents 18 states that planted 92 percent of corn acres and 96 percent of soybean acres across the United States in 2017.

    According to the survey, corn planting is slightly ahead of schedule compared to the 2013–2017 average for acres planted this time of year, with 92 percent completed. The recent dry, summer-like temperatures in the Midwest over the past few weeks have let growers catch up after a later-than-normal start to planting this year. And an estimated 72 percent of the U.S. corn crop has emerged, slightly ahead of last year at this time and above the 2013–2017 average of 69 percent. Of the corn that has emerged, three percent is listed in very poor to poor condition, 18 percent in fair and 79 percent in good to excellent condition. Corn seems to be right on track for most of the Corn Belt.

    For soybeans, things are moving ahead of schedule. At this time in 2017, 65 percent of soybeans were planted. This year, 77 percent are in the ground, which is 15 percent higher than the 2013–2017 average. Of soybeans planted, 47 percent have emerged, which is also ahead from last year (34 percent) and the 2013–2017 average (32 percent). States like Wisconsin, South Dakota, North Dakota and Iowa still have a way to go, but soybean-producing states in the South are close to having their crop fully emerged. Soybeans conditions are not yet being reported.
