I came outside today to see these ghostly white patches on my pumpkin leaves. This is a Connecticut Field pumpkin plant and I'm not sure if this is powdery mildew or a regular leaf pattern common in this variety.
Not sure, check the back of the leaf also. Does it look fuzzy??
Nevermind thank you for your help but I think it's just a pattern of the leaves because all of the new leaves after this just naturally have this pattern.
Yeah, this is just natural silvering of the leaves.
Yeah, I wonder what makes pumpkin plants mottle their leaves like this? Maybe aphids or other plant harming insects think it resembles a moth or something harmful to them.
