OHP Adds to Greenhouse Grower Options for Weed, Insect Control
OHP, Inc. is enhancing its offerings to greenhouse growers with an updated organic label for one of its insecticides, as well as the launch of a new herbicide.
Pycana Insecticide/Miticide, part of the company’s biosolutions offerings, has received Organic Materials Review Institute (OMRI) listing. Pycana is a unique combination product containing natural pyrethrins and canola oil that provides quick knockdown of many insects and mites including aphids, thrips, whiteflies, spider mites, leafhoppers, earwigs, plant bugs, psyllids, mealybugs, and more.
Pycana is labeled for use on ornamentals, fruits, vegetables, and herbs, grown in greenhouses, shadehouses, hoophouses, and in container nurseries.
Biosolutions is a segment of the OHP product line comprised of products that are specifically designed to address the increasing number of growers who use biological pest control programs.
New Herbicide Targets Broadleaf, Grassy Weeds
OHP has also announced the federal registration of Fortress Ornamental Herbicide, a pre-emergent granular product that provides control of broadleaf and grassy weeds.
Fortress provides weed control without harming sensitive plants such as perennials and grasses, and may also be applied to woody ornamentals.
“Fortress has shown outstanding crop tolerance on many crops, including softer plants, while providing excellent weed control, especially on crabgrass,” says Dave Barcel, OHP Senior Technical Manager. “We’ve also seen good control of broadleaf weeds such as bittercress, marestail, oxalis, spurge, and others.”
Fortress is a combination of the active ingredients isoxaben and dithiopyr, both widely used as weed control options.
Formulated on an engineered granule, Fortress produces virtually no dust and low odor, resulting in improved worker safety and ease of application.
“The engineered, high-performing granules are uniformly round and do not hang up in the crop canopy,” Barcel says. “The result is better plant tolerance and improved weed control.”
Fortress will be available in most states in mid-October.
