Dow has recently received a label for use of Quintec on Winter Squash, Gourds and Pumpkins. The only disease that this fungicide is labeled for is powdery mildew. Our research trials over the past few years have shown that this is a very good product for control of cucurbit powdery mildew. Please see attached label for details of usage. Thanks, Steve Additional information: r-136-022-quintec-sec-3-for-control-of-powdery-mildew-on-winter-squash-gourds-and-pumpkins-pdf
