  4. Changes to labeling for Engenia (BASF), XtendiMax (Monsanto) and FeXapan (DuPont) for 2019

    Both commercial and private applicators should note changes to labeling for Engenia (BASF), XtendiMax (Monsanto) and FeXapan (DuPont) for 2019. If these products will be part of your 2019 herbicide program please review the revised labels and requirements. Of special note is the change that only license applicators can purchase, mix, load, apply or clean application equipment removing the “supervision by a certified applicator” option for these products.

    The complete news release with more details is shown below.

    REYNOLDSBURG, Ohio (Jan. 16, 2019)- The Ohio Department of Agriculture (ODA) is reminding farmers of revised labels and new training requirements for applicators who intend to use dicamba herbicide products this year. In October 2018, U.S. EPA approved revised labels for the three dicamba products that are labeled for use on soybeans: Engenia (BASF), XtendiMax (Monsanto) and FeXapan (DuPont).

    “Like any other product, we want to ensure licensed applicators are properly following label directions as they get ready for this growing season,” said Matt Beal, chief of the ODA Division of Plant Health. “This not only helps ensure the safe use of pesticides, it also helps prevent misuse and mishandling.”

    The manufacturers of these dicamba products also agreed to additional requirements for their products. Some of the requirements include:

    • 2019 labels supersede all prior labels for these products. Applicators must obtain a copy of the new label and must have that label in their possession at the time of use
    • Only certified applicators may purchase and apply the products
      • Those operating under the supervision of a certified applicator may no longer purchase or apply.
      • Anyone who mixes, loads or cleans dicamba application equipment must become licensed.
      • ODA will host additional “Dicamba Ag Only” exams in February and March for those looking to become a certified applicator. Visit for more details.
    • Applicators must complete dicamba-specific training
    • Increased recordkeeping requirements
    • Wind speed restrictions
    • Temperature inversion restrictions
    • Sensitive/susceptible crop consultation
    • Spray system equipment clean-out

    More details on these revisions can be found in the attached fact sheet. Applicators looking for a list of ODA-approved trainings can visit For questions, applicators can contact the ODA Pesticide and Fertilizer Regulation Section at 614-728-6987 or

  6. Is Foliar Feeding an Economical Way for Organic Dairy Farmers to Boost the Quality and Quantity of Forages?

    Is Foliar Feeding an Economical Way for Organic Dairy Farmers to

    Boost the Quality and Quantity of Forages?

    Full Project Proposal can be found here

    PI: Dr. Douglas Doohan (Professor) & Louceline Fleuridor (Master’s Candidate), OSU/OARDC Horticulture & Crop Science.

    Farmer: Ron Milner (Milner Farms, Holmesville, OH).


    This project aimed to evaluate the effectiveness of using repeated foliar applications of plant nutrients to maintain high quality alfalfa and mixed grass forage on organic dairy producer farms. Our results did not show consistent, overwhelming benefits of this practice to maintain or increase forage yield or quality, with effectiveness varying across farm fields, crops and cuttings throughout the growing season.

    What was done? 

    Foliar feeding (application of plant nutrients to leaves) is becoming an increasingly popular practice used by organic dairy producers to manage forage quality throughout the growing season. However, the few scientific studies investigating this practice do not support its effectiveness, especially considering farmer investment in foliar nutrient products. We conducted an experiment in 2018 on seven alfalfa-mixed grass forage sites of four organic dairy farms in Wayne and Holmes Counties. The experimental design was a randomized complete block (RCB) with four replications of two treatments: Treatment

    #1, control (standard organic management program), which typically involves the application of organic manure in the fall and again in spring, and Treatment #2, the standard management program plus foliar application of a custom blend of two SoilBiotics products, Organic Blend 5-0-0 (9 L/ha) and eFISHnt 5-1-2 (18 L/ha). Treatment #2 was applied at first green-up and 10 days after each cutting for three applications. We collected data after treatment but before the next cutting to estimate forage yield (based on dry weight of biomass samples), in-field plant health (based on NDVI, normalized difference vegetation index), and various forage quality parameters: crude protein, soluble protein, acid neutral detergent fiber, relative forage quality, relative forage value and Brix (sugar content) (based on lab tests of fresh samples). We also collected soil and tissue samples for mineral nutrient analysis before and after the growing season. We performed analysis of variance (ANOVA) (PROC GLM procedure in SAS 9.4) to determine significance between the treatments for any variables measured.

    What were the results?

    The foliar feeding practice did not increase yield or in-field plant health for any of the sites and cuttings. While a few forage quality parameters were significantly higher or lower than the controlled areas, the inconsistency across sites and cuttings limited the inferences that can be made. No visually detectable effects were observed between the foliar-fed plots and the untreated plots.

    How have the results contributed, or will they contribute to sustainable agriculture?

    Organic dairy operations in Ohio and elsewhere face considerable challenges to stay in the market, and they are forced to minimize their production costs. Foliar feeding is a unique approach to survive in a struggling market, giving hope of a much higher quality feed product through a practice that is convenient and relatively inexpensive. However, most, if not all, foliar feeding recommendations come either from business owners or other farmers, with no scientific evidence that this practice is effective. It is important for universities to contribute with research that can help increase understanding of the validity of this practice or improve its efficiency. The results of this experiment were shared with farmers through one-on-one meetings that involved cooperating farmers and foliar fertilizer company representatives to discuss directions of future trials and recommendations for product improvement. More importantly, this project involved organic farmers, the industry (SoilBiotics) and the university, providing a tremendous opportunity for all three groups to learn and work together for the betterment of farmers and sustainable agricultural production.

  7. Optimizing Anaerobic Soil Disinfestation to Increase Ohio Strawberry Productivity

    Full Project Summay can be found here

    Introduction: Black root rot of strawberry is a destructive disease caused by one or more multiple fungal pathogens including Fusarium spp., Rhizoctonia spp. and, Phythium spp. Black root rot can occur on strawberry produced using matted rows and black plastic. Historically, soil fumigation with methyl bromide was used to control black root rot.  However, methyl bromide is no longer registered for strawberries in Ohio. Other soil fumigants can be used but they typically don’t control all of the pathogens responsible for black root. Four to five years of rotating out of strawberries can lower black root rot incidence and severity but long rotations are not economical for strawberry growers. Anaerobic soil disinfestation (ASD) is a relatively new practice that encourages anaerobic decomposition of carbon based amendments, allowing for the accumulation of volatile compounds that kill pathogens and weed seeds. In tomatoes and other vegetable crop production systems one ASD treatment has been shown to control soilborne diseases for 2-3 years. Anaerobic soil disinfestation is a promising tool for strawberry growers to manage black root rot (and weeds) and will work directly in conjunction with current plasticulture production systems. The objectives of this project were to evaluate the efficacy of ASD in reducing black root rot disease incidence and severity on strawberry and to identify the most effective and economical carbon source to be used against black root rot during ASD.

    Methods: An on-farm trial to evaluate ASD was initiated at Catalpa Grove Farm. Two carbon sources (wheat bran and molasses), a mixture of the two carbon sources, a chemical control (azoxystrobin plus aluminum tris) and a non-treated control (Table 1) were evaluated in a field with a history of black root rot disease. The trial consisted of four replications. Carbon treatments were incorporated into the test plots on 17 Jul, flooded, and covered with black plastic. Ten soil temperature probes were randomly placed under the black plastic to monitor soil temperature and removed on 2 Nov. Bare root strawberry (cv. Chandler) plants were planted on 5 Sep. Transplants for the chemical treatment were dipped in a mixture of azoxystrobin (8 fl oz/100 gal) and aluminum tris (2.5 lb/100 gal) prior to planting. Foliar disease incidence was rated on 5 Oct, 19 Oct and 2 Nov. Foliar disease incidence will be rated an addition two times in the spring and root disease severity will also be assessed (see proposal).

    Project timeline.

    Because new strawberry plantings are planted in the fall (September to October), the anticipated grant period is July 2018 to March 2019. Recognizing that this does not fit into the granting period of the Paul C. and Edna H. Warner Endowment Fund for Sustainable Agriculture we request that the final report be allowed to submitted no later than April 1, 2019.  A project report summary that includes items described in this request for proposals would still be submitted by December 29, 2018.

    The anticipated grant period is 07/01/18 to 3/1/19.
