No potato blight fungicide on beet

SUGAR beet growers must not apply potato blight fungicides to volunteer potatoes emerging in their crops, warns IACR Brooms Barn.

Blight sprays are not cleared for use in beet and applying them would put sugar beet contracts at risk, it warns.

If volunteer potatoes are a concern treat with a recommended mix containing clopyralid (Dow Shield) and triasulfuron (Debut), to achieve a faster knockdown of volunteer potato foliage than clopyralid alone, it advises.

Where beet are large enough, having 6-8 true leaves, consider using salt to defoliate the volunteer potatoes, it adds. &#42
