Title: Tomato leaf disease.
Post by: amphibian on July 08, 2009, 19:34:56
This has appeared suddenly, well since I last looked on Monday, on three of my tomato plants, all adjacent to one another. It is present on leaves of all ages, stems are clear of any disease but some flowers are dropping, but may be due to poor pollination. Pictures of overside and underside.

Opinions?

Yeah, there are a minimal number of aphids and black fly, literally just a few here and there, they seem more interested in the cleavers that grows in the fence behind. There are no infested leaves, no colonies in the folded areas, or anything that would constitute an infestation.

There are two aphids visible in the picture of the underside.

Amphibian,
Just wondering whether this could be a leafminer, as it shows the characteristics of their traits.

Try holding a leaf up to the light. If it's leafminers you should be able to see them inside the leaf.

Nothing visible. I have been out and stripped all affected foliage. No sign of any spread since yesterday.

there was a thread recently in connection to warering chillies and tomatoes and cucerbits  was suggested that adding milk to the water at a ratio of 7-1 would have a advantage to preventing disease
i have done a check on A$A this is not the first organic method of milk was previously suggested in 2004 this link will give some fore information for you http://www.allotments4all.co.uk/smf/index.php/topic,52880.0.html   

 I will add i have tried this on one tomato plant this year with simular problem as above i have myself seen a result allready from the milk foilage has gone a lush green and the infected area is healing itself without the need to cut the damage foilage of i separated the watering program from other plants to identfy the results
all i can say it seems to be working for me could be a cobination of weather change but the milk in my opionion has made a difference

That's me on the way to the greenhouse with the milk bottle then!  ;D ;D

One of my tomato plants which I put in the porch suddenly developed blossom end rot on the half a dozen fruits it had, so having looked up the cause and cure,, I now feed more and check watering needs.  I hope to report that this has cured the problem!!  ::) ::)
