HARVANTA™ 50SL Gives Vegetable Growers a New Option for Broad Spectrum Insect Control
Posted at 9:00 AM on September, 21 2017

Summit Agro USA announces EPA approval of HARVANTA™ 50SL insecticide, now available to U.S. vegetable growers for use on fruiting vegetables, cucurbits, leafy vegetables and brassica (cole) vegetables.

Containing the proprietary active ingredient CYCLAPRYN®, HARVANTA 50SL is a new broad-spectrum diamide insecticide. HARVANTA 50SL has consistently demonstrated equal or superior control of the most troublesome insects in vegetables, compared to existing diamides and other classes of insecticides, including pests resistant to organophosphate, pyrethroid and carbamate insecticides. Trials show that it has excellent efficacy against Lepidoptera insects, including Diamondback moth, a major economic pest in vegetables.

HARVANTA 50SL provides this high level of control while using less active ingredient per acre as compared to other IRAC Group 28 insecticides. It has an excellent safety profile with beneficial arthropods.

“We are proud to first bring this new chemistry to the United States,” says Fred Yates, product manager at Summit Agro USA.  “We think vegetable growers will find multiple benefits.  In addition to a broad spectrum of activity it is fast acting, with long residual control. HARVANTA has also shown excellent larvicidal activity with adulticidal activity in many insect species. It is an excellent addition to their Integrated Pest Management (IPM) and Insect Resistance Management (IRM) programs.”

HARVANTA™ 50SL insecticide is distributed in the USA by Summit Agro USA LLC, and sold exclusively through Tenkoz member companies and Helena Chemical Company.
