As the diary says, this problem is affecting all the new leaves past the pumpkin set. The leaves are normal in shape and size but seem to take longer to form. I've had this problem for a couple weeks and it has not got any worse. In fact, it seems exactly the same.
The older leaves that first started showing this problem actually look a little better in their maturity if anything. Thanks for any help any one can provide!

I was under the impression that within two weeks my entire plant would be crippled, including the set pumpkin. The pumpkin I do have set is at 19 days and about 120lbs and is growing faster every day still. Will I notice more problems here shortly, or what should I expect?

I would give it a good shot of Liquid Iron...or something with Manganese. Manganese deficiency can look like Mosaic

I agree with LVP...your leaves in June looked very similiar....

Appreciate the responses. Unfortunately, I'm in Korea and have a hard time sourcing English (read, 'readable') fertilizers/amendments. Any ideas on sources that I might be able to find here? I do have access to a base exchange which has limited American products, since I am military.
Thanks again!

Can you get a soil or tissuse test there? Recommendations are easy if you can tell us what deficiencies exist.

How do the little pumpkins look?

Anything like these..

If so then the odds are likely you may have a virus.

I am not sure what the native soil type is for Korea so there is a chance that various nutrients may be more of a problem. Soil test would be great piece of information if it is possible to get one.

I do not have that problem, Matt, but I do have a problem with BER on all new sets. Here's my latest diary entry with a pic/more info.

Thanks again guys.

And I do not know where I could get a soil test here. I realize it's pretty much a guessing game matching symptoms with causes without a test, but hey that's better than ignoring the problem.

Well, maybe, as long as I proveed slowly with whatever I do apply :-)

To me I do not think you have mosaic virus even though the plants are showing mosaic-like symptoms. Lack of data and understanding of the area environment do make it difficult to work on a step-wise diagnosis process compared to the shot-gun (try a bunch of things) approach.

Personally, my suggestion it to try and get a pH test of the soil. pH is very common and all you need is some soil distilled water and a pH probe. The reason why I am suggesting this is that it is a fairly easy test (you can even by a pH probe) and is the key to nutrient availability. I have saved farmers a lot of money on fertilizer and had them simply correct their pH and all of a sudden yields increased with no fertilizer added. The key is availability and nutrient lock-out could be happening in your case.

So, instead of adding this or that try and get an idea of the pH as this can also offer insight into what the soil maybe high (or low) in naturally.

Hope this helps.

If you have a virus you will know soon typically they will abort the kin at 200 to 300 lbs,Looks like Matt is right,but that is a funky looking leaf you got with all the speckles on it.

Virus infected plants will not necessarily abort the pumpkin. If the pumpkin is under 20 days old the odds of it being deformed are much higher (because of my theory in cells in a pumpkin only divide for the first 20-days) and as a result this could lead to the integrity being compromised which could result in the pumpkin not making it to maturity. However, if the pumpkin is older than 20-days the pumpkin will most likely continue to grow but the rate will be reduced because the plant being infected with the virus is not as efficient.

The virus infected plant that I had last year continued to grow until I picked it even though I was cutting the plant back to gain some insight into the virus. I also know of a fellow grower that had two different types of virus identified in their plant material and they were able to grow a pumpkin over 1,000 pounds.
