Ron, Sometimes after applying a paste of fungicide I will use my hair dryer to make sure this mixture is hard. You don't want a fungicide to stay wet on the pumpkin or stem. You can also spray the stem once a week and reapply fungicide. Try to mix up the sprays. I start with Captain then Ridomil/Bravo. The hair dryer forms like a "cast'' on the stem. I also will use a fan to dry out the stem end of the pumpkin. Very important to keep thr area around the pumpkin dry.Hope your big ones hang in there! Only 5-weeks till harvest!!!!!!!!!!!!!!
