Canada approves Bayer's flupyradifurone insecticide and DuPont's oxathiapiprolin fungicide

The Canada's Pest Management Regulatory Agency (PMRA) has proposed to grant full registration for the sale and use of Bayer CropScience’s Flupyradifurone TC and the end-use products BYI 02960 480 FS and Sivanto Prime Insecticide (previously known as Sivanto 200 SL) containing the technical grade active ingredient flupyradifurone to control various insect pests. The flupyradifurone has been approved in US and EU. The agency has opened the public comments for 60 days until Jan 25, 2016.

Flupyradifurone is an insecticide in a new Mode of Action (MoA) Subgroup (Subgroup 4D, the Butenolides), that interferes with the function of insect nerves. MoA Group 4 also includes the neonicotinoids (4A), nicotine (4B) and sulfoxaflor (4C). Flupyradifurone is active by ingestion and contact, but is more potent via ingestion. This active ingredient is systemic when applied as a soil treatment and has translaminar activity when applied as a foliar treatment. Formulated as BYI 02960 480 FS and used to treat soybean seeds, it controls soybean aphids and adult bean leaf beetles. Formulated as Sivanto Prime Insecticide and sprayed on the foliage of various field, vegetable, fruit and nut crops (for example, leafy vegetables, legumes, fruiting vegetables, cucurbits (except cantaloupe), pome fruit, berries, tree nuts, corn, alfalfa, peanut and hops), flupyradifurone controls aphids, leafhoppers, scale insects, whiteflies, Colorado potato beetle, and blueberry maggot and suppresses pear psylla. When applied as a soil application to fruiting vegetables, cucurbits (except cantaloupe) and berries and small fruits, Sivanto Prime Insecticide controls aphids, leafhopper and whiteflies. This product can be applied by air to tuberous, corm, root and legume vegetables.

The Agency is also granting full registration for the sale and use of DuPont Zorvec Technical Fungicide, Dupont Zorvec Enicade Fungicide, Dupont Zorvec Epicaltrin Fungicide, Orondis Fungicide, and OXTP 200SC Fungicide, containing the technical grade active ingredient oxathiapiprolin, for use against selective oomycete diseases on bulb vegetables, brassica (cole) leafy vegetables, cucurbit vegetables, fruiting vegetables, leafy vegetables, ginseng, tobacco, succulent shelled and edible-podded peas, and potatoes.The public comments for 60 days have been opened until Jan 27, 2016.

Oxathiapiprolin is a new conventional fungicide active ingredient that prevents spore initiation and inhibits growth in susceptible fungi. It represents a new mode of action not previously available to Canadian growers.
