has primary responsibility for development, registration and logistics for Ishihara Sangyo Kaisha, Ltd.’s products in the Americas. ISK Biosciences brings several new agricultural products to serve a growing, global market.
The Sumitomo Corporation/Ishihara Sangyo Kaisha (ISK) joint venture, Summit Agro USA (Durham, North Carolina), has introduced Verdepryn™ insecticide, with the active ingredient Cyclapryn, offers growers exceptional broad-spectrum insect control in pome fruit, stone fruit, grapes, berries, tree nuts and citrus. It has been launched by Summit Agro USA. Verdepryn is powered by the same active ingredient as Harvanta®, used in vegetable crops. This insecticide offers competitive control to other diamides while using much less active ingredient.
Summit Agro USA has introduced the post-emergence maize herbicide, Shieldex®400 SC (ISK’s tolpyralate 400 g/litre), in the US. The hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor controls a range of broadleaf weeds and grasses including “troublesome” weeds such as Palmer amaranth/ tall water hemp (Amaranthus spp), giant ragweed (Ambrosia trifida) and giant foxtail (Setaria faberi), the company points out. Shieldex 400 SC will be distributed exclusively by Summit Agro USA’s partners, Helena Chemical (Collierville, Tennessee) and Tenkoz (Alpharetta, Georgia). The EPA proposed the approval of tolpyralate in May. ISK Biosciences submitted applications for joint review by the EPA and the Canadian Pest Management Regulatory Agency. The latter proposed to register the herbicide in September.
The Canadian Pest Management Regulatory Agency (PMRA) has approved Ishihara Sango Kaisha’s insecticide, Cyclaniliprole 50SL (cyclaniliprole 50 g/litre). It is for the control or suppression of various insect pests on a range of fruit, vegetable and tree nut crops. The PMRA proposed the approval in late July. The review was conducted jointly with thr US EPA, which proposed registration in May and granted it in August. ISK began selling cyclaniliprole in South Korea this year and expects introductions in the US, Canada, Australia and Japan.
ISK has announced the appointment of OHP to distribute its new Group 7 fungicide isofetamid in the US ornamental markets. Astun fungicide was registered by USEPA 71512-23, 2017 and will be launched this fall following completion of necessary state registrations.

The US EPA has proposed the approval of Ishihara Sangyo Kaisha US subsidiary ISK Biosciences’ insecticide, Cyclaniliprole 50 SL (cyclaniliprole 50 g/litre), for use on a range of fruit and vegetable crops. The soluble liquid formulation is for use on pome and stone fruit, nut trees and grapevines at 16.4-22 fl oz/acre (1.2-1.6 litres/ha) and on brassica and non-brassica leafy vegetables, fruiting vegetables and cucurbit vegetables at 10.9-16.4 fl oz/acre.
