New insecticide label information for compounds listed in 2017 E0154

MSU Fruit Management Guide E0154 product numbers are in parenthesis ().

Belt (89) (flubendiamide). The U.S. Environmental Protection Agency (EPA) has cancelled the registrations of flubendiamide-containing products, including Belt insecticide. EPA will permit distributors and retailers to distribute and sell remaining flubendiamide inventories, and permit growers to continue using product consistent with label use directions until Dec. 31, 2019.

Tourismo (92) (flubendiamide/buprofezin). EPA has cancelled the registrations of flubendiamide-containing products, including Tourismo insecticide. EPA will permit distributors and retailers to distribute and sell remaining flubendiamide inventories, and permit growers to continue using product consistent with label use directions.

Closer (8) (sufloxaflor). On Oct. 14, 2016, EPA re-established the registration for products containing sulfoxaflor (Isoclast Active): Closer SC insecticide. This re-established registration will allow for post-bloom usage on pome fruits, stone fruits, grapes and tree nuts. This registration has a downwind buffer zone included and restricts tank-mixing with products containing certain active ingredients.

Endosulfan phase-out. EPA has completed action to end the use of the pesticide endosulfan. A formal Memorandum of Agreement with manufacturers of the agricultural insecticide has led to cancellation and phase-out of most endosulfan uses in the U.S., and the phase-out period is complete for all fruit crops.

Banter (61) (bifenazate) belongs to a class of miticides called carbazates and is registered for use in pome fruits, stone fruits, grapes, strawberries and caneberries for mite control. Banter is a contact miticide that is primarily active against motile stages of European red mite and twospotted spider mite, but also has ovicidal activity against spider mite species. For best performance, maintain spray tank water within a range of pH 5.5 to 6.5.

New insecticide label information for compounds not listed in 2017 E0154

Minecto Pro (cyantraniliprole + abamectin) is an insecticide/miticide that combines two active ingredients as a pre-mix formulated compound. Minecto Pro is registered for use in pome and stone fruits, targeting mites, leaf miners, leafrollers, psylla, plum curculio, codling moth, oriental fruit moth, leafrollers and fruit flies. Minecto Pro holds the combined performance attributes of the cyantraniliprole and abamectin chemistries.

For the purposes of resistance management, do not make more than two sequential applications of Minecto Pro, and products containing either one of cyantraniliprole or abamectin shouldn’t be used in the subsequent generation. The maximum yearly amount of Minecto Pro to be applied is 24 ounces per season.

Cormoran (novaluron + acetamiprid) is an insecticide that combines two active ingredients as a pre-mix formulated compound. Cormoran is registered for use in pome and stone fruits, blueberries and strawberries targeting aphids, leafhoppers, leafrollers, fruitworms, codling moth oriental fruit moth, stink bugs (brown marmorated stink bugs) and fruit flies (spotted wing Drosophila). Cormoran holds the combined performance attributes of the novaluron and acetamiprid chemistries.

For the purposes of resistance management, products containing either one of novaluron and acetamiprid shouldn’t be used in the subsequent generation. The maximum yearly amount of Cormoran to be applied is 35 fluid ounces in strawberries, 89 fluid ounces in blueberries and 95 fluid ounces in pome and stone fruits per season.
