Dreaded Tomato Blight

It appears that blight seems to be a problem in my area so I will just have to keep spraying if I ever want a good crop of home grown tomatoes.

This years crop so far - half a cherry tomato.

Leggi, is this what your problems have looked like?

Dreaded Tomato Blight

You're not crossing enough fingers!  

This morning two of my Marmandes have black patches on the main stems   As soon as OH is up and has had a cuppa, I'll get him to move them away from the others (I slipped a disc last week )  

Although one of them is the only one with large toms on so far,  I think I shall have to bite the bullet and bag and bin them in order to protect the others - oh it's fun this gardening lark, isn't it?

Can you post a couple of photos - stems, foliage, fruit - before they go to Tomato Heaven?

Thanks Italophile 

I've just been reading this http://www.harrowinleaf.org.uk/tomatotrials.html

very interesting.

Dove, it is interesting, but a pity they just use the generic term Blight. They really should be identifying the pathogen(s). Anyway, the results are unsurprising. Once the spores are in place and doing their dirty work you can't (so to speak) kill them. Any anti-fungal action must be preventive.

Grafted tomato plants

You could say that the jury's still out on grafted toms, christopher. Some swear by them, others consider them an expensive folly. I lean towards the latter. They are often sold with claims of disease resistance but there are any number of traditional hybrid varieties around bred for the same disease resistance. Bearing in mind that resistance means just that - they will still become infected, but will battle on a bit longer.

Still, the only test is to try grafted alongside traditional and see what happens.

Powdery mildew.

Jean, a baking soda-based spray is commonly used against powdery mildew. Give it a try.

Leggi, if the stems are quickly turning black it sounds like it could be Late Blight. If so, there's no saving the plant.

In general, spraying once any fungal disease symptoms are already present is a waste of time and money. It's too late. Spraying has to be preventive, meaning you spray before the spores arrive, starting a couple of weeks after planting out, then weekly or so afterwards, respraying if it rains.

Spraying doesn't guarantee you won't get fungal disease but it gives you a solid defence.

Dove - good luck!

I would like to know how to pinch the tops out of the tomatoe plants and when to do it.

 

Janet, you only need to pinch out the tops of tomatoes (a) if you want to limit the plant's height in restricted growing space (eg, a greenhouse); and (b) later in the season when any new flowers won't have time to produce fruit.

To pinch out the tops - identify the plant's leaders, the main vertical stems that are producing branches and flowers, and cut off the top inch or so.

is there any kind of POT that you should NOT use to grow herbs and veg in ?
Thanks Helen

Helen, a pot really just needs to be big enough to do the job you're asking of it and with adequate drainage. As to types of pots - smaller pots will dry out quicker than larger ones, plastic pots will dry out quicker than ceramic or terracotta.

Hello,
I have looked at the guides on greenhouse tomatoes and they are very useful. I have grown three sorts of tomatoes Moneymaker (normal size), Legend (beefsteak) and cherry tomato too. Are they all treated the same in the greenhouse re removal of axilliary shoots, number of trusses and so on? Does one size fit all?
Thanks
Valerie


The quote function seems not to be working. Valerie, the basic mechanics of tomato growing are the same regardless of variety.
