I noticed this blight on my tomato plants, the older leaves gone yellow and spotty, while the new growth looks fine.
Plants are still young, about 5" tall, outside.

I have no idea what it is. Maybe someone could help and offer a remedy?
Thanks in advance.

Might seem a silly question, but were the seeds you used freebees from a magazine?

mosiac virus?  :?

[sawnee]

Magnisium deficiency (spelling) :?

[PeterR]

The plants were bought from Wyvale garden center 99p each.

2 Beef tomatoes, which looks not too bad, 2 plum tomatoes which are the worse and 1 cherry tomato plant also pretty badly affected.

If it is contagious, I will have to rip them out and bin them or it could spread to other plants like courgettes, beans and aubergines?

Thats definately the mosiac virus, the leaves are a yellowy broze colour, tear off al the bronze leaves and burn them! A drastic messure but it can lead to deformed fruits. If it hasnt spread your ok, to prevent it spreading, spereate the clean plant from the infected ones, then take off anything broze from the infected, and bun it, then wash your hands and check the ok looking ones. If it comes back, on the same plants your going to have to burn the plant. I know from experience.

Good luck

I have cut off the affected leaves and disposed of them.

If this virus comes back, and spreads, I will throw out the plants and get other ones. I have only five pots for them, so not worth the risk of spreading to other vegetables.

Mosaic Virus

CONTROL:
Unlike fungicidal chemicals used to control fungal diseases, to date there are no efficient chemical treatments that protect plant parts from virus infection. Additionally, there are no known chemical treatments used under field conditions that eliminate viral infections from plant tissues once they do occur. Practically speaking, plants infected by viruses remain so. Thus, control of tobacco mosaic virus is primarily focused on reducing and eliminating sources of the virus and limiting the spread by insects. Tobacco mosaic virus is the most persistent plant virus known. It has been known to survive up to 50 years in dried plant parts. Therefore, sanitation is the single most important practice in controlling tobacco mosaic virus.

Thats why you burn anything bronze, at least it gives the plants a chance. I also found this onsome randome site after typing "a spray for the mosiac virus" in Google

Dilute i litre of milk with 9 litres of water. Spray the solution every after 10 days to prevent mosaic virus in tomatoes

Its probably a load of bull, but you never know.

do* you smoke tobacco?

edited sorry  :oops:

[PeterR]

so you smoke tobacco?

Nope, Non smoker! Nobody came near with any smoking either.

So far no other plants are affected. Even if I destroy the tomatoes, the soil  still will have the virus.  :shock:

I don't think it's virus, Peter. The third picture looks a simple cold damage, not much to worry about. Keep a fleece handy for colder nights.

The browny bits might be something. Could you have a photo of sick looking leaf in background in first picture and also a green looking one and stalk close up high and near ground, please?

[PeterR]

Well, comparing photos from the web, it is the virus.

But, having cut off the affected bits, so far it is looking reasonable.
Maybe I'll get away with it.

Fingers crossed.   :thumright:

I'd go with the milk thing, we sell paint buckets by the hundreds, together with disposable latex gloves to the tomato greenhouse company here so that they can mix up the milk mixture and rub it onto the leaves.If it works for them there must be something in it and their greenhouses are vast!

[WhippetMaster]

Ive got a similar thing to photo 3.Plants are in my unheated greenhouse the has been subject to extreme temperature differences. 35C during the day dropping as low as 4C at night.

Again noone has been in contact with my plants and it's my first year growing any kind of vegetables. They were grown from seed using bagged compost so it would be difficult to contract a virus.

I agree that it does look like mosaic virus perhaps my plants and photo 3 are in the early stages???

I hope not!!!

that looks like something showing on some weed leaves I sprayed with round up a week or so ago...not had spray drift from someone's plot or garden have you?  :shock:
