August 1, 2019
OHP, Inc., announces the introduction of Pradia™ Insecticide to the ornamental nursery and greenhouse markets.
Pradia is a broad-spectrum, innovative and novel combination product developed for control of both sucking and chewing insect pests on ornamentals.
The combination of active ingredients – cyclaniliprole and flonicamid — provides quick knockdown and lengthy residual activity of many troublesome pests including whiteflies, thrips, aphids, leafminers, armyworms, moths and caterpillars, loopers, plant bugs, Japanese beetles, lace bugs, and beetles including flea beetles.
“We are pleased to offer Pradia to our nursery and grower customers,” says Dan Stahl, OHP vice president and general manager. “The unique combination makes it an ideal, fast-acting, broad-spectrum insect control solution.”
In addition, the combination product offers another advantage.
“The systemic and contact activity offered by Pradia makes it an ideal choice for use on hard-to-control sucking and chewing insect pests,” says Dr. Carlos Bográn, OHP manager technical service. “Plus the combination of two active ingredients with overlapping spectrums of control will aid in preventing resistance to diamide insecticides on key pests such as thrips, whiteflies, and aphids.”
Compatible with parasitic wasps, predatory mites, and lady beetles, Pradia is ideal for use as a tool in an IPM program.
Pradia is formulated as a user-friendly soluble concentrate in quart containers and has a 12-hour REI.

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).

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.
