EPA Approves Special Registration for Fungicide on Seed Potatoes


HELENA, Mont. -- The U.S. Environmental Protection Agency has approved temporary use of a microbial fungicide on seed potatoes grown in Montana to minimize occurrence of a potato virus known as PVY.


BmJ WG Microbial Fungicide, manufactured by Certis USA, can be applied on seed potato fields from June 14 to August 15, 2012 under an EPA Section 18 emergency exemption for Montana only. Applicators must have a copy of the current label in their possession and follow all label instructions, according to the Montana Department of Agriculture.


PVY is spread by aphids. Use of insecticides to control aphids is the common method for keeping seed potatoes free of the disease, along with in-field roguing to remove infected plants. The foliar fungicide provides an additional method of curbing the spread of PVY, which is a major disease of potatoes.


A copy of the fungicide product label is available from the department's website at For more information, contact Linda Johns at (406) 444-3676 or by e-mail at
