Is this Mosaic Virus?

[nelliegemini]

and if not, does anyone know what it is?

I received two Red Kuri squashes as big plug plants on 16th April through the post and planted them on immediately into 4" pots as they had been a bit battered in the packaging (but that is another story!).

They looked OKish then today I noticed the yellow mottling

I have searched the 'is this Mosaic' threads but can't see anything that looks like this.

They are in new multi purpose compost and both of the surviving plants are showing the mottling. They haven't been outside and are in a tray with young peppers, tomatoes, basil, borlotti and french beans, peas - all of which look fine (she said, frantically searching out for wood to touch)!

Any advice please?

I would say it looks more like scalding to me, water on the leaves hit by the hot sun.

[nelliegemini]

Dunno, since the plants have been with me they've only been watered from below and there hasn't been any hot sun (if only!).

Is this something that could have happened before they left the nursery and taken a couple of days to develop? I am assuming that the plants were in transit for some time because the compost was bone dry and one of the beans in the set had grown enough to contort in the packaging. (mutter, mutter).

Thanks Paulw, I couldn't really see anthing that looked like my problem, because the fruits haven't fruited yet. I will investigate these sites thoroughly of course and see if they provide any clues.

[nelliegemini]

OK PaulW, I've had a look and since there is no distortion I will assume it is a cultural thingy rather than the virus.

The plants still seem fine in themselves, but presumeably still in shock as they are not romping away.

Thanks for your help.

I find squash types do that rather a lot. They still fruit ok. There was a bit of discussion last year about it.

[nelliegemini]

Well, they've gone outside now to start hardening off! The sun is shining, the east wind has dropped and it's time for the little darlin's to leave home (until this evening that is).

Glad to hear it's not unusual for squash types, first time I've really tried, I put in one bns outside last year and it grew two proper leaves then stopped - so I don't have much experience. The previous chat about it all seemed to be 'do I have mcv?', 'no!' - so I could never find out what it looked like and the leaves look exactly like the picture in Hessayon, but there is no distortion. Anyway, fingers firmly crossed and will see how we do.

Thanks again all for advice, comments.
