OHP Announces Two New Ornamental Pest Management Tools

Parasitized aphid mummies, ladybird beetle larvae

OHP recently added two new crop protection tools to its profile of biosolutions.

One of the products is Thuricide N/G Biological Insecticide, which is derived from a naturally occurring bacteria and infects lepidopteran larvae and other insect larvae. Thuricide N/G contains the bacteria Bacillus thuringiensis subspecies kurstaki strain SA-12.

Thuricide N/G is the latest of several additions to the OHP biosolutions segment of new tools for crops grown in greenhouses, nurseries, and the landscape — including vegetables and herbs. Thuricide N/G is approved for organic production and is Organic Materials Review Institute listed.

“Thuricide N/G is another great tool in our biosolutions segment,” says Dan Stahl, OHP Vice President and General Manager. “We feel strongly that providing solutions for growers who use not only conventional, but other means of pest control, is of great importance to our industry as habits are changing rapidly.”

After a Thuricide N/G application, insect larvae consume the bacteria. Once in the insect gut (stomach), the cryotoxins are released, causing the larvae to stop feeding and subsequently die within a few days.

Use of Thuricide N/G fits well into a pest control program utilizing beneficial insects or predators, says Dr. Carlos Bográn, OHP Technical Manager. Bográn also notes that Thuricide N/G should be used at the first sign of pest infestations for optimal results and in a rotation with products from different classes with different modes of action.

Thuricide N/G carries a 4-hour Restricted Entry Interval (REI) and Caution signal word.

OHP Adds Astun Ornamental Fungicide to Portfolio

OHP also recently added Astun Ornamental Fungicide to its stable of pest and disease solutions. Astun provides botrytis control with the active ingredient isofetamid, a new fourth-generation member of the SDHI class of chemistry, mode of action (MOA) group 7.

“We are excited to add Astun to our portfolio,” Stahl says. “We anticipate Astun will become an integral part of a botrytis control rotation for our grower partners.”

Astun provides preventative, systemic, and curative activity on ornamentals grown in commercial greenhouses and nurseries. According to Bográn, it is most effective when used as a protectant fungicide applied when conditions are right for botrytis development, but before the disease damages the crop.

Formulated as a user-friendly Suspension Concentrate (SC), Astun can be tank mixed with other partners for a broader spectrum of control.

“In recent years, certain botrytis strains have become resistant to products used against the disease,” Bográn says. “Astun offers an option with no reported resistance against botrytis.”

Astun carries a 12-hour REI and Caution signal word.

More information on Thuricide N/G and Astun, including label, SDS, and product information, can be found at ohp.com.

On December 1, Eric Wallien of Roberta’s Inc. in Waldron, IN, officially purchased C. Raker & Sons in Litchfield, MI. The new identity of the company is now Raker-Roberta’s Young Plants, according to a Dec. 1 letter to Raker’s customers, suppliers, and business partners from Vice President Susie Raker-Zimmerman. “There have been minimal changes in management and we will be providing the same products and services on which we have built our reputation in the industry,” Raker-Zimmerman said in the letter, which also announced the name change and new logo. The sale of C. Raker & Sons was announced in September . A series of events affecting Raker’s financial situation caused the need for the operation to find an alternate solution. Roberta’s had been a customer of Raker’s since 2011, and the fourth generation, family owned grower-retailer was a fan of Raker’s commitment to quality. The agreement to purchase C. […]
