We use only Warrior T for insects and a variety of fungicides including Compass, Banner, Immunox, Manzate and Stylet Oil with baking soda. We also use Holland's Bio Endo product in our potting soil and mound area.
The growing season was about the hottest and driest that I can ever remember. There were a lot of nice warm nights though and this seemed to help quite a bit. We could have used a lot more rain though. Two of our 4 plants did suffer a lot from the heat, which resulted in slow growth. Another fruit split and rotted a week before the weigh-off.
The 1469 took right off though and never paused. It averaged well over 40 lbs. per day at it's peak growth period. In mid august, the first of 2 large sag lines appeared but the fruit somehow made it intact to weigh-off day. When it was cut open we saw that the cracks were paper thin at the surface. There were over 600 seeds inside but only 180 mature ones. I believe the pumpkin was trying to grow much heavier but simply did not have quite enough food. Possibly the plant needed to be a little larger, or maybe it just needed a few good rains.
When I started growing pumpkins just a few years ago, I wondered if it could possible to grow a pumpkin over 1000 lbs. Next I wondered if it could be done this far south in Pennsylvania. I think that if you are a new grower, you must believe that you can do it too. Get to know your soil very well and talk to other experienced growers in your area.
Many of them will be glad to help. If you want to be truly successful, you must get into it 100 percent and be willing to spend the time necessary. If you do not enjoy it, you are wasting your time. Good luck out there.
