The new formulation of Marengo G allows for easier application and provides the same effective performance.

We’re pleased with the initial response and market acceptance we saw with the original Marengo G formulation,” notes Dan Stahl, OHP vice president of marketing and business development. “We feel Marengo G produced on the new granule will result in even greater market penetration.

The new Marengo G formulation, with its active ingredient indaziflam, is produced on granules that utilize the proprietary Verge® technology, resulting in larger, heavier, and more uniform particles that offer several advantages for users:

  • Reduced dust for less applicator exposure;
  • More uniform coverage;
  • More accurate, on-target applications even in breezier conditions;
  • Less chance for plant injury as the heavier particle rolls freely off of plant surfaces

The new formulation looks and handles much like Biathlon®, another quality OHP herbicide, notes David Barcel, OHP senior technical manager for herbicides and PGRs.

Both Marengo G and Biathlon are produced utilizing the Verge granule technology,” says Barcel. “We have received nothing but positive feedback from Biathlon users and anticipate the same with Marengo G.

Marengo G offers effective, long-term pre-emergent control of both broadleaf and grassy weeds with little effect on desirable plants. The product does not volatilize and does not move in the soil once it is watered-in after application.

Marengo G can be applied over-the-top of containers in nurseries, and may be applied in hoop, shade and lath houses.

OHP is a leading marketer of pest and weed control solutions to the production ornamentals market.

Pollinator update: Insecticide alternatives.

September 5, 2014

At OHP we pride ourselves for bringing the very best crop protection tools into the US ornamental production market. Recent events in the news have sparked a lot of discussion and questions regarding the impact of neonicotinoid insecticides on honey bees and other pollinators.  This has led some growers and retailers away from this family of insecticides which includes some of the most effective and environmentally safe insecticides available today. We are proud to have been the first to bring Neonicotinoid insecticides into our market 20 years ago and we continue to support the use of these important tools in accordance with science based EPA regulations.

Although we continue to support the use of Neonicotinoid insecticides, we understand that growers are looking for chemical alternatives to manage insect pests. Unfortunately there is no single insecticide product  or family of products that provides the breath and length of activity as Marathon®, Discus® (Imidacloprid) or the other neonicotinoid insecticides. However, for growers seeking alternatives, OHP carries an extensive and diverse portfolio of chemical solutions. These include Kontos® (Spirotetramat), and many other insecticides like Judo® (Spiromesifen), Decathlon® (Cyfluthrin), Fulcrum® (Pyriproxyfen), Pedestal® (Novaluron), Adept® (Diflubenzuron), Azatin® O (Azadirachtin) and Triact® (Neem oil).

Kontos is a systemic insecticide for the control of sucking insect pests. Systemic insecticides are incorporated by the plant after application and move from treated surfaces to untreated ones, thus providing better protection than contact-insecticide sprays.  All systemic insecticide molecules available today can move acropetally (towards the tips of the plant) via the xylem but, often because they are highly water-soluble, do not effectively move basipetally (towards the base of the plant) in the phloem.  Kontos is a true systemic insecticide; once in the plant, it converts into a molecule with the perfect combination of characteristics for xylem and phloem mobility.  Kontos is one of very few insecticides available today that is able to move ‘up and down’ the plant and provide complete protection against key pests.

Kontos is also friendly to our environment; since it works within the plant tissues, it is non toxic to pollinators and other insects that do not feed directly on the plant’s sap. Kontos is very quickly degraded by microorganisms in the soil and on the plant surface and it is used at such a low concentration (less than 0.03% by volume) that the chemical load on the environment is very low compared to traditional chemistries.  Also, since it works by inhibiting lipid synthesis (fat reserves) in the developing insects it has little effect on most adult predators and parasitoids that have already developed these fat reserves. Therefore, Kontos is highly compatible with biological control programs within an integrated pest management (IPM) strategy.

Kontos should be used early in the crop cycle to prevent pest damage and not as a rescue treatment; it takes time for the product to reach lethal concentrations within the xylem and phloem tissues and to get translocated through the plant. Applications targeting small initial pest populations not only are more effective but also minimize aesthetic damage and plant losses.

OHP Inc. announced today that it has entered into a marketing partnership to add Segway® O Ornamental Fungicide to its productSegway O Ornamental Fungicide from OHP, Inc. portfolio.

As part of the agreement with ISK Biosciences Corp, OHP will provide sales and technical support beginning May 19 for Segway O to production ornamental growers. Segway O provides excellent control of oomycete diseases such as pythium, phytophthora crown and root rot, phytophthora aerial blight, and downy mildews.

We’re thrilled to add Segway to our product portfolio,” said Dan Stahl, OHP vice president of marketing and business development. “It’s a great fit into a rotational disease control program with our existing fungicides Aliette® and Terrazole®.

Cyazofamid, the active ingredient in Segway O, is a proprietary product of ISK and is the only member of fungicide Mode of Action (MOA) Group #21, making it an ideal candidate for inclusion into a disease control rotational strategy, noted Dr. Carlos Bográn, OHP technical manager for insecticides and fungicides.

Effective as a spray or drench, Segway O provides control of 7 to 28 days, depending on disease pressure, noted Dr. Bográn.

OHP will deliver Segway O in a convenient 16 oz. container that accommodates the average greenhouse and nursery user.

We’re excited to form another partnership with an outstanding technology provider, ISK Biosciences,” said Terry Higgins, OHP vice president and general manager. “With the power of the OHP brand and our marketing, sales, and technical support, we expect Segway O to become fully established in the greenhouse and nursery markets in short order.

OFA & ANLA join together, now AmericanHort

October 3, 2013

Email this article

COLUMBUS, Ohio — After two years of planning, the national trade organization to be formed through the consolidation of OFA – The Association of Horticulture Professionals and the American Nursery & Landscape Association (ANLA) is official. And it finally has a name: AmericanHort.

AmericanHortMembers of OFA and ANLA voted in overwhelming support of the consolidation of the two organizations into a new, national trade association to serve the entire horticulture industry. The announcement followed a 30-day open ballot and Saturday’s in-person vote for OFA’s members, held in Columbus, Ohio.

It’s what our members want,” said Mark Foertmeyer, who was announced as the chairman of the board for the new organization. The owner of Foertmeyer & Sons Greenhouse in Delaware, Ohio, and current president of OFA continued, “We have surveyed our members, spoken with them, and finally asked them to cast a ballot. Each time they told us they wanted a national association that unifies and serves the entire horticulture industry.”

The new trade association, named the American Horticulture Association, will be known as AmericanHort, and will begin operations by Jan. 1. The mission of AmericanHort is to unite, promote, and advance our industry through advocacy, collaboration, connectivity, education, market development, and research.

The dues structure for the new organization has not yet been finalized. Members of OFA and ANLA as of December 31, 2013 will automatically become members of the new association in January 2014. Membership will continue through June 30, 2014. The dues renewal process for the new association will begin in the spring for the membership year beginning on July 1, 2014. The new dues structure will allow members to choose from an a la carte menu, said Michael Geary, CEO of OFA and vice president of ANLA. Dues will no longer be based on business size or revenues.

We will have the largest national nursery, greenhouse, and garden retail membership of any horticulture association in the United States,” said the organization’s inaugural vice chairman, Dale Deppe, owner of Spring Meadow Nursery in Grand Haven, Mich., and current vice president of ANLA. “Those communities will join together with breeders, distributors, interior and exterior landscape professionals, florists, students, educators, researchers, manufacturers, and all who are part of the supply chain to represent our industry with one, strong voice and a greater base of volunteer, staff, and financial resources,” Deppe added.

Michael Geary, CAE, who will continue as the chief staff executive, said the new association will maintain all of the current staff in both the Columbus, Ohio and Washington, D.C. offices.

By including research, industry promotion, regulatory and legislative efforts, education, and countless opportunities for buyers and sellers to interact, we will deliver a broad range of business-based services to our industry and be the quintessential resource for the horticulture industry as a whole,” Geary said.

I have made long-term dues investments in both organizations,” said Gary Mangum, CEO of Bell Nursery, headquartered in Elkridge, Md., and a current member of both ANLA and OFA. “ANLA is the leader in legislative and regulatory representation for our industry, and OFA offers outstanding educational programs and runs the largest horticultural trade show and convention in North America. With the addition of programs like the Next Level conference and the significant expansion of the retail segment at the 2014 Short Course, we can already see the benefits of these two associations joining together. It will be better for my business, and it is a true win for our industry. Congratulations to our leaders and members who made this historic decision.”

The new organization will represent the whole of the plant industry, including breeders, greenhouse and nursery growers, garden center retailers, distributors, interior and exterior landscape professionals, florists, students, educators, researchers, manufacturers, and all of those who are part of the industry supply chain. The association will have its primary office in Columbus, Ohio and an office in Washington, D.C. to facilitate government relations and research activities.

The inaugural board of directors was appointed by the legacy organizations. For the first year, the board will have equal representation from OFA and ANLA. The board includes the following leaders:

  • Chairman of the Board – Mark Foertmeyer, Foertmeyer & Sons Greenhouse, Delaware, Ohio
  • Vice Chairman of the Board – Dale Deppe, Spring Meadow Nursery Inc, Grand Haven, Michigan
  • Treasurer – Lisa Graf, Graf Growers, Akron, Ohio
  • Past Chairman of the Board – Mike McCabe, McCabe’s Greenhouse & Floral, Lawrenceburg, Indiana
  • Past Chairman of the Board – Bob Terry, Fisher Farms, Gaston, Oregon
  • President & CEO – Michael V. Geary, CAE, AmericanHort, Columbus, Ohio/Washington, DC
  • Joe Burns, Color Burst, Grayson, Georgia
  • Teri Cantwell, Bates Sons & Daughters Inc, Lake Placid, Florida
  • Tom Demaline, Willoway Nurseries Inc, Avon, Ohio
  • Bob Jones Jr, The Chef’s Garden, Huron, Ohio
  • Terri McEnaney, Bailey Nurseries Inc, St Paul, Minnesota
  • Dan Mulhall, Mulhall’s Nursery, Omaha, NE
  • Morris Newlin, New Garden Landscaping & Nursery, Greensboro, North Carolina
  • Cari Peters, JR Peters Inc, Allentown, Pennsylvania
  • Sid Raisch, Horticultural Advantage, Hillsboro, Ohio

The organization will have a new committee structure in place by the end of the year.

We want the governance structure of the committees to be simple,” Geary said. “We’re creating a new system in terms of how we interact with members.”

That includes an “enhanced strategy” to connect members with state and regional associations. ANLA’s Lighthouse program will continue, which includes some 13,000 people throughout those “partner” organizations, Geary said.
