| The first picture has the spots on the leaves, if you go to the 2nd photo, you'll see a different problem, kind of like a yellowing, spotting pattern. What do you think each of the problems are and do you have any suggestions? Thank you so much! |
|
| The first is powdery mildew, the second is just a normal pattern that appears on some types of squash as the vine reaches maturity. I personally do very little for powdery mildew. Early in the season I just remove leaves as it appears, but once it gets a good foothold I just remove leaves as they start to die. Powdery mildew can affect many different plants so be sure to remove infected plant debris at the end of the season. |
|
| Thanks Trev, so I guess I'll do the same. Remove the affected leaves now and get rid of all debris after they're done growing. I appreciate your taking the time to respond! Vicki |

| If you want to stay organic/ pesticided free you can purchase organic sulphur and make a sulphur tea to spritz on the leaves. It should kill off the powder mildew. I have had the same problem on our summer squash and table queen squeen squash. It didn't affect our tomatoes though so I am wondering if I boil some tomato leaves if that would work too! |

| As of this morning my pumpkins and zuchinni plants are covered with this white spot stuff and I mean everywhere. Yesterday they were fine. The pumpkins are quite a good size. Do I just leave them alone this late in the season or is there something I should do. Please help and thanks. |
|
| if you could post a picture kinda hard to say what it is. if your pumpkins are close to being ripe i wouldnt worry about it. |
|
| Thanks Terry. My camera is dead this morning but the spots are exactly what was described above I think as powdery mildew. So you think I should just let them be? Do I keep watering them? Thanks. |

| It would depend on exactly how widespread the damage is.. which is why pics would help. Are all leaves infected or just some of them? |
|
| Baking soda makes an inexpensive control for powdery mildew on plants. The baking soda fungicide is mostly effective as a preventative, offering only minimal benefits after your plants have become infected. Weekly spraying of susceptible plants during humid or damp weather can greatly reduce the incidence of powdery mildew in your garden. To control powdery mildew on plants, mix together: 1 tablespoon of baking soda or you can buy the more expensive fungicide. this late in the season give it a try. |

| It is most of the leaves and not the pumpkins themselves. Some of the leaves are totally white/gray and look dead the rest just have the spots. I want to remove the dead leaves but not sure where to cut them off at. The top of the stem or the bottom? At this late stage in the season and with them being almost totally orange, is it necessary to spray or could I still just let this go? Thanks. |
|
| let them go. give them a good drink of water. they will finish on there own. |
|
| Thanks Terry. I removed ALL of the bad leafs and gave them a nice drink from the bottom of the plant with my hose and I'm praying they will do just fine and I'm sure they will if you say so. I also cut down all of the bad leaves on the zucchini plants which are right next to the pumpkin plant. Also I don't think I mentioned it but I only have one pumpkin plant but it has three pumpkins on it and they look fantastic. So cross your fingers. I hope also by getting rid of all of the bad extra vines and leaves the pumpkins will get more of the water for themselves and maybe even grow a bit more. |

| Powdery Mildew or other diseases are almost a given late in the season.. you can control it to a degree but the plant itself is doomed in most climates anyway since it will die as fall/winter encroaches anyway. The goal is to maintain as good a leaf structure as possible and minimize disease to give the plant time to grow and mature the most amount of pumpkiny goodness. |
