New Product Corner

 This new section of the IR-4 Newsletter called ‘New Product Corner’ was suggested by grower stakeholders as a way for IR-4 to help inform specialty crop growers about new pest management tools recently registered by EPA. This is for informational purposes only as IR-4 does not endorse a particular product or registrant. 

CYANTRANILIPROLE (Cyazypyr®) (Insecticide - DuPont)

Introduction: On Feb. 5, 2014, tolerances were established by the EPA for the new active ingredient (AI) cyantraniliprole (Cyazypyr®) on multiple commodities. Regulatory scientists from EPA and counterpart agencies from several other countries conducted a global joint review of the dossier. This AI, discovered by DuPont, belongs to the anthranilic diamide class of chemistry. It is the second AI in this chemistry, but the first to provide growers with a new pest management tool for cross-spectrum control of chewing and sucking/sap-feeding pests. DuPont has developed single AI products, and two of those have been registered and approved by EPA under the brand names Exirel™ and Verimark™. Syngenta Crop Protection has rights to develop pre-mixes. With no cross resistance to other classes of insecticides, cyantraniliprole may be especially useful against target pests that have developed resistance to other insecticides. It is classified as a Group 28 insecticide by the Insecticide Resistance Action Committee (IRAC).


Other global registrations: Argentina, Australia, Canada, China; more country registrations are expected in the near future

PYRIFLUQUINAZON (Insecticide – Nichino America, Inc.)
Introduction: Unconditional registration for the new active ingredient (AI) pyrifluquinazon was granted by the EPA in January 2013 for non-food uses on ornamental horticulture plants grown in greenhouses. This new chemical registration provides greenhouse growers with a new pest management tool for use against various sucking (sap-feeding) insects such as whiteflies (including Q-biotype), aphids, mealybugs, leafhoppers and chilli thrips. Belonging to a novel class of chemistry, pyrifluquinazon represents a new mode of action, characterized by modification of insect feeding behavior (through contact and translaminar activity) which has not yet been classified by the Insecticide Resistance Action Committee (IRAC).
Other global registrations: Japan (for outdoor uses on over 20 food crops) and Korea

US trade names/formulations: For ornamental horticulture uses, pyrifluquinazon will be marketed by SePRO as Rycar™ (20SC).

US labeled crops*:
Known tolerant ornamental horticulture crops (although pyrfluquinazon can be applied after testing other species): Begonia, Impatiens, Marigold, Petunia, Verbena, Zinnia

General use pattern for non-food greenhouse uses: use in dilution rates of 1.6-6.4 fl. oz./100 gal, applied at a rate of 10 gal of spray solution/1,000 ft2, and maximum of 2 applications per crop cycle.
IR-4 Ornamental Horticulture Program current research: thrips outdoors, leafminers, crop safety.
IR-4 food use project requests (PR#) progressing toward registration: cantaloupe (10431), cucumber (10428), greenhouse cucumber (10793), greenhouse lettuce, head and leaf (11202), bell and non-bell pepper (10430), greenhouse bell pepper (10555), greenhouse tomato (10126), squash (10429), watermelon (10432)
