Tomato Blight

Aberdeenshire, United Kingdom Gb

How do you prevent late blight in tomatoes ?
I tried to grow mine organically but got blight two
years in a row and nearly lost the lot so now I am
forced to spray.



I had blight last year due to the wet weather, this year I have grown them in the greenhouse to prevent this.

I have found this link dont have plastic near either when growing hope this will help for the future also garlic planted by a lot of plants deters pest of most kinds. I have a blog on this if you wish to have a look the link I have saved this to my favourites too.

It was probably the wet weather over the last two years....and this one it seems! I've not bothered with outdoor toms this year - mine are in the greenhouse.

Make sure you aren't planting the toms in the same spot year after year. The blight can stay in the soil for a while apparently.

I think its the wet weather that has destroyed my tom crops and have tried to space mine out as far as possible this year. I'm even thinking of rigging some kind of clear plastic roof to stand above them. Its a greenhouse for me next year :~((

I have toms growing inside and outside this year , fortunately so far no sign of blight , as soon as the first fruit have set I remove the leaves up to this first truss , this lets air circulate around the plants , think this helps ,dont know if it's the only reason

Thanks for comments. I AM growing some of the
tomatoes in the greenhouse but they seem to get
blight wherever I put them. I,m forced to use Dithane
and don,t want to. How can you grow this crop
organically when you get blight every year ?

Just a suggestion but if you are planting your seed(lings) directly into the ground then that could be your problem. Blight can "live" in the soil from one year to the next. If you use a solution of Jayes fluid and water from a watering can at the end of the season, this should kill off the bacteria. Not very organic I know but I've lost another crop this year again and am desperate to get at least one tomato to ripen.

Can I suggest you read some of the blogs by N2organics. He grows everything organically and is very knowledgable on soil structure etc.
Good luck.

Thanks to Ian digs v2 for suggestion about Jeyes Fluid. Good idea but think Armillatox might do the job even better ! My blight seems to get into both tunnel and greenhouse and unless I spray with Dithane its hopeless !
