OHP adds Sarisa Insecticide to portfolio
August 1, 2019
OHP is excited to announce the introduction of Sarisa™ Insecticide, a revolutionary new product for broad-spectrum control of insect pests on 
ornamental greenhouse and nursery stock.
The active ingredient in Sarisa, cyclaniliprole, provides extended residual protection against key nursery and greenhouse pests such as thrips, beetles including flea beetles and Japanese beetles, armyworms, gypsy moths, loopers, plant bugs, lace bugs, and leafminers.
“Sarisa offers many attributes that make it an outstanding product to use today and into the future and we’re happy to introduce another tool to help both our nursery and greenhouse grower customers manage their insect control,” says Dan Stahl, OHP vice president and general manager.
A diamide insecticide, Sarisa provides quick knockdown and residual activity of sucking as well as chewing insects with its novel mode of action and has a 4-hour Restricted Entry Interval (REI).
The active ingredient in Sarisa assists in the conservation of many beneficial insects such as predatory mites, parasitic wasps, and lady beetles, notes Dr. Carlos Bográn, OHP manager technical services.
“The selectivity of the active ingredient allows beneficial insects and other arthropods to continue to manage secondary pests,” says Dr. Bográn, making Sarisa compatible with IPM and resistance management programs.
Sarisa is formulated as a user-friendly soluble concentrate that may tank mixed with appropriate partners. The use of a spreader sticker may help performance.

OHP FireWorxx herbicide now available
July 16, 2019
FireWorxx™ is a OMRI-listed post emergent herbicide for control of weeds in greenhouse, nursery and landscape ornamentals, 
grounds maintenance, and non-cropland areas. FireWorxx is a fast-acting, non-selective broadleaf weed, grass, algae and moss killer. FireWorxx is not translocated. It will burn only those plant parts that are coated with spray solution.
FireWorxx can be used any time during the year and works best during sunny, warm and dry conditions. Application during cold weather may delay appearance of plant damage. If rain falls within 3 hours of treatment, an additional spray may be required. FireWorxx controls many common annual weeds and suppresses the growth of biennial and perennial weeds. It can be used in cultivated areas prior to planting crops. Treated areas can be re-planted as soon as desirable level of weed control is obtained.
OHP Pedestal Insecticide – New changes!
June 24, 2019
There are some key changes upcoming with OHP’s Pedestal® Insecticide, an effective insect growth regulator against Thrips and other pests.
Effective immediately, any new Pedestal produced and purchased will have a new EPA registration number, new product code, and be packaged in OHP packaging. State registrations for the current Pedestal will be maintained for the near future so that distributors and growers may exhaust their inventory.
The new EPA registration number is 53883-419-59807. Package size, use rates, REI of 12 hours, and insects controlled remain the same.
Pedestal, with the active ingredient novaluron, is a suspension concentrate formulation labeled for use on ornamentals and tomatoes grown in greenhouses and nurseries. Among the insects controlled are thrips, whiteflies, armyworms, stink bugs, and more.
California registration is pending.

Kalmor Fungicide/Bactericide – Now registered in California!
April 23, 2019
We are pleased to announce the immediate availability of of Kalmor® Fungicide/Bactericide through authorized OHP distributors.
Kalmor, part of OHP biosolutions™, is an OMRI-listed, copper hydroxide-based fungicide that is labelled for use on a range of vegetables and herbs grown in greenhouses, shadehouses, and nurseries, for control of many problematic fungal and bacterial diseases.
Available in an easy-to-use dry flowable formulation, Kalmor is labelled for control of alternaria, bacterial leaf spot, botrytis, cercospora leaf spot, downy mildews, fire blights, needlecasts, pseudomonas leaf spots, xanthomonas leaf spot, and other diseases.
Kalmor represents a superior copper hydroxide formulation comprised of smaller particles than other copper-based products, notes OHP Manager Technical Services Dr. Carlos Bográn. The smaller particles mean you need less product to do the same job as other copper products. Kalmor use rates range from 0.5 to 2.0 lbs. per 100 gal. of water.
Kalmor is effective against resistant strains of certain diseases, making it an ideal choice in an IPM program, adds Dr. Bográn.
As with any copper-based products, users should check compatibility with other products before tank mixing. Kalmor should not be tank-mixed with OHP’s Areca® Fungicide or other aluminum-based products.
Kalmor is a natural tank-mix partner with OHP’s Triathlon® BA Biofungicide/Bactericide for broad spectrum control of many troublesome fungal and bacterial diseases.
Kalmor is packaged in a 2.5 lbs. bag, four to a case. For availability, please contact your local distributor sales representative. Thank you for your support of our Kalmor launch.

Grower has success controlling Botrytis with Astun fungicide.
April 3, 2019
This past fall and winter produced great conditions for the development of botrytis on greenhouse crops. Based on information from OHP and others, and an application last spring, Jim Stepp, production manager at Van Wingerden International, decided to apply Astun™ Ornamental Fungicide to more crops.
Jim continues: “We also used it last spring on pansies and violas with very good results. We sprayed it with full flowers and saw no damage. We used Astun on fuchsia baskets before they were hung with overhead drip lines as a preventative and it performed very well. We felt like we got good systemic action.”
Last fall, Jim used Astun to prevent botrytis on VWI’s finished cyclamen program. “Our cyclamen were very clean even in some very wet, cloudy weather. There was no damage to open flowers. We used a spreader sticker and had no visible residue on the cyclamen flower,” he says.
“We feel like this product is very effective, safe on all crops we have tried it on, and is a great tool in the fight against botrytis.”
