Bicyclopyrone

The Canada's Pest Management Regulatory Agency (PMRA) has proposed to grant full registration for the sale and use of Syngenta’s Bicyclopyrone Technical, the manufacturing concentrate products Bicyclopyrone Wet Paste I and Bicyclopyrone Wet Paste II, and the end-use product SYNA16003 Herbicide, containing the technical grade active ingredient bicyclopyrone, to control specific weeds in field, sweet and seed corn. Also granted full registration is Acuron Herbicide, containing the active ingredients bicyclopyrone, atrazine, s-metolachlor and mesotrione to control specific weeds in field, sweet and seed corn. The public comments have been opened until Sep 30, 2015.

Bicyclopyrone is a Group 27 Herbicide. It acts in susceptible plants by inhibiting the biosynthesis of carotenoids and leading to the destruction of chlorophyll. The mode of action of bicyclopyrone is shared with several other commercial herbicide active ingredients, specifically, mesotrione, isoxaflutole, topramezone, tembotrione and pyrasulfatole. Bicyclopyrone is efficacious against select broadleaf weeds as well as proso millet (a difficult to control grassy weed).

Pasteuria nishizawae

The agency is also granting full registration for the sale and use of Syngenta’s Pasteuria nishizawae Technical and Clariva pn, containing the technical grade active ingredient Pasteuria nishizawae Pn1, to suppress soybean cyst nematode in soybean.

Pasteuria nishizawae Pn1 is a mycelial and endospore-forming bacterium, naturally found in North American soils, which parasitizes the adult females of cyst-forming nematodes, such as the soybean cyst nematode (SCN - Heterodera glycines).

Paecilomyces fumosoroseus strain FE 9901

The agency is granting full registration for the sale and use of FuturEco’s NoFly Technical and NoFly WP, containing the microbial pest control agent Paecilomyces fumosoroseus strain FE 9901, for the control of whiteflies and thrips in greenhouse ornamentals. The public comments have been opened until Sep 29, 2015.

Spinosad

The agency is granting full registration for the sale and use of Scotts Canada's Spinosad Technical Insecticide and Ortho Home Defense Max Ant Bait Stations, containing the technical grade active ingredient spinosad, to be used in a bait station to control ants and ant colonies. The public comments have been opened until Sep 29, 2015.

Spinosad is a fermentation product of the bacterium Saccharopolyspora spinosa that must be eaten by the pest to be effective. It acts on insect nerves, causing paralysis and death. Products containing spinosad are also registered for use on greenhouse food and ornamental crops, outdoor food and ornamental crops and turf against a wide variety of insect pests.
