Label Additions for Presidio

Bob Mulrooney, Extension Plant Pathologist;

Valent USA just reported that brassica leafy vegetables, root and tuber vegetables, potatoes and carrots have been added to the Presidio label. The other good news is that the rotation interval for wheat has been reduced from 18 months to 30 days. Hopefully this will be the beginning of the reduction of the other rotational intervals for other crops that follow cucurbits that have limited its use for downy mildew control in pickling cucumbers particularly. The supplemental label is available online here: Presidio is an excellent fungicide for cucurbit downy mildew control and will be another excellent fungicide for control of late blight and pink rot on white potatoes.
