Help - we have potato blight and tomato blight
« on: May 07, 2010, 18:06 »
Anyone else having this problem? :(  Potato leaves blackened at the edges and shrivelling up, tomato plants I found in the greenhouse today with yellowy blotches all over the leaves, shrivelling up...

It seems very early for blight, and the conditions haven't been right for blight to strike.  Are you sure it is blight or is it maybe something else getting to your potatoes and Tomatoes.

If you could put up a piccy there may be some on here who could identify what it is.

I would of thought it actually more likely to be frost that's got to them rather than blight.  By the way, a hard frost is forecast for Monday night so   get the fleece ready.

Frost on the spuds and magnesium deficiancy with the toms i hope.

I dont think it has been warm and damp enough for long enough to spread blight unless you have diseased plants from last year.

I'm on the Buckinghamshire border and havn't had any alerts from Blightwatch.  Far too early.
Cheese makes everything better.

most likely cause is frost damage. blight is not about this time of the year, conditions are all wrong for it. is the greenhouse heated as toms require a min of 8degrees c.tates will get over it ok but toms will struggle unless you can warm them up a bit at night.

Just a thought - have you used any manure at all? Could be aminopyralid (hope not)  :(

No chance that it's blight.

Most likely frost

Frost I reckon.  I had a little damage on the early crop spuds at the end of one of my rows where the fleece blew off.  A few leaves went black and dried out pretty quickly in the warm day.  Nothing to worry about.  In so much that you don't have blight.

Yellowing on Toms is very likely a Magnesium deficiency. What sort of compost are you using for the seedlings? 

You can use Epsom salts to cure this but I do not know the protocol for treating seedlings/young plants.  Or for that matter where to buy Epsom salts.  (Boots?)  Hopefully someone with a bit of experience in this specific area can help.   

I do know that what ever you are feeding them is not working so you have to treat the problem first because the toms will not continue grow as they are.

It's not the end of the world, treat the ones that you have but to be safe I'd go ahead and plant more tomatoes now and they'll all catch up soon enough.

I'd advise looking in the Garden Centre before the Chemist. Although you probably don't need very much I've found Chemist price/weight much higher than Garden Centre.
