Problems with my corgettes

I am having some major problems! Most of my leaves seem to have yellow blotches on them, the only thing I can find to do with it is cucumber mosaic virus, but it doesnt have some of the symptons- it doesnt have dark green blotches and it doesn't have mis-shapen leaves. Has anyone ever come across this? My soil is quite sandy, and I was wondering if it is something to do with the pH.

Any ideas or tips? I don't want to loose my plants!

:o)

Hi there! Funny thing I just learned - what you call corgettes, we call Zucchini on this side of the pond ! See, I learn something new and interesting every day :) Before I get cocky though - we are talking about the large squash plant, aren't we?

If it were indeed the mosaic virus affecting your plants, from what I have read there is no cure for a viral disease in plants. Removal of infected plants and preventing infection in the first place are the only solutions. Aphids are the main transmitter for the mosaic virus, so their control is important to prevent it from spreading to the rest of the garden.

However - if the only symptom you see is the small yellow blotches on the leaves, and it otherwise looks healthy, then I would suspect some other culprit. It could be several things, but the following link is the only one that I have had personal experience with on squash plants.

If you see no squash bugs or eggs, then it possibly could be a fungus or a disease. See if any of the following are more descriptive of your symptoms :

Good luck!

Thank you, that is really helpful. For now I have just removed the affected leaves and am going to hope for the best!

Thanks again :)

Sminkah,

There is the following thread on the tomato discussion board "Damaged tomato leaves, no obvious cause" which has symptoms similar to which you are describing (my melons are suffering the same I think). One of the main ideas is that they are in a windy area and they are losing moisture from the leaves (which I think might be leading to sun scald??) Our melons are on the raised deck (patio) which on hot days 75f ++ leads to a west east wind as the sun moves around the house. This wind can blow quite strong during the day with the temperature differential in the housing estate leading to 10mph plus winds at 2-4pm in the afternoon.
I'm personnally going to keep perservering as the palnts seems healthy with continued growth and flowering.
Good luck and keep us informed.

zucchini

I have never heard the term corgettes before either. Gotta love "talking" with gardeners from other continents. Learn something new every day :lol:

It looks different to the tomato leaves posted on the forum but they are a different crop so I guess it may look different. I think it may be the cucumber mosaic virus :(, although I removed the affected leaves and they now seem to be ok. There is one plant which I left the affected leaves on and it seems to be ok at the moment, though one of the leaves collapsed and went brown. Although they are in quite a windy position so maybe you are right... I will just have to keep a close eye on them and like you said they seem to be flowering and fruiting so that is the main thing!

P.S. It is meant to be courgette (I spelt it wrong!!)
