Consultation on Bacillus amyloliquefaciens strain MBI600 and Bacillus subtilis strain QST 713 and the Associated End- use Products, Proposed Re-evaluation Decision PRVD2022-09
Notice to the reader:The online consultation is now closed
Health Canada is consulting Canadians on the proposal to continue registration of products containing Bacillus amyloliquefaciens strain MBI600 and products containing Bacillus subtilis strain QST 713 registered for sale and use in Canada. No additional mitigation measures are proposed; however, updates to product labels as per current labelling standards are proposed.
Bacillus amyloliquefaciens strain MBI600 is a naturally occurring bacteria which suppresses plant diseases by preventing growth of pathogenic fungi through displacement and direct antagonistic action. Bacillus amyloliquefaciens strain MBI600 (formerly Bacillus subtilis MBI600) has been registered in Canada since 2004 as a treatment of plant growing media such as soil and peat moss-based mixtures to suppress seedling and root diseases caused by various fungal pathogens. It is also registered for foliar use on greenhouse and/or field vegetables and fruits, in-furrow application on potatoes, as a soil drench to greenhouse cucurbits, fruiting vegetables and ornamentals, and as a seed treatment on canola, corn, soybean, dried shelled peas and beans.
Bacillus subtilis strain QST 713 has been registered in Canada since 2007. Bacillus subtilis strain QST 713, is antagonistic toward fungal and bacterial plant pathogens and is a microbial pest control agent for agricultural use, as well as for home garden use on ornamentals, fruits and vegetables. It is used to suppress a number of bacterial and fungal plant pathogens. It is registered for commercial use on a variety of crops, including greenhouse vegetables/herbs (including wasabi), greenhouse ornamentals, corn, herbs and spices, canola and oilseeds, mushroom production, vegetables, potato, pulses, peanut, soybean, sugarbeet, grape, pome fruit, stone fruit, cane berries, bush berries, small fruit, tobacco, outdoor ornamentals and turf.
Bacillus amyloliquefaciens strain MBI600 and Bacillus subtilis strain QST 713 have a non-toxic mode of action and have value in providing pest management solutions. Based on the current use patterns of Bacillus amyloliquefaciens strain MBI600 and Bacillus subtilis strain QST 713, the potential health and environmental risks are considered to be acceptable when products are used according to label directions.
For a full list of products containing Bacillus amyloliquefaciens strain MBI600 and Bacillus subtilis strain QST 713, please consult Appendix I in the Proposed Re-evaluation Decision or visit the Pesticide Label Search database.
For more information on the proposed decision open the “Proposed Re-evaluation Decision”.
