Mar. 6, 2013, Calgary, Alta – Pome and stone fruit growers in Canada now have access to Closer, a new insecticide for the control of aphids and San Jose scale.

Canada’s regulatory authorities have approved Closer for use in all pome and stone fruit crops. Closer will control numerous aphid species including apple aphid, spirea aphid, rosy apple aphid and woolly apple aphid.

The active ingredient in Closer is Sulfoxaflor, an insecticidal molecule developed from a new class of insecticides called sulfoximines.

Effective at low use rates, Closer is very fast acting and provides extended residual control. Closer provides systemic and translaminar activity, ensuring control of hidden pests in the plant canopy and on the undersides of leaves. A rotational partner with other chemistries, Closer is effective on insect populations resistant to other insecticide classes such as neonicotinoids, organophosphates and pyrethroids.

“Closer provides super-fast knockdown of insect pests and is a welcome addition to pome and stone fruit pest management programs,” says Jerry Olechowski, marketing manager with Dow AgroSciences. “Closer exhibits complex and unique interactions with important receptors in the insect’s central nervous system different from those observed with neonicotinoids. It exhibits no cross-resistance in insects that are resistant to neonicotinoids, a tremendous advantage for managing resistant populations.”
