Blight on tomatoes

**Jungle Jane** · 03-09-2016, 01:04 PM

Hello this has happened to a lot of us,its something you get used to with tomato plants & a good reason for crop rotation,avoid planting tomatoes in that area for about 3 years I think? I could be wrong or over protective of tomatoes maybe? The plants 10m away will hopefully be fine I wouldn't touch those but keep checking them. I had blight on two of my plants,got rid of them & my tomato plants 1m away are fine,that happened over a month ago. Wash all equipment you use to get rid of the blighted plants & yes take the green tomatoes off the blighted plants.

OK thanks Jane

Keep any green toms to see if they ripen but keep an eye out in case they develop the disease. You can plant in the same ground next year, blight only overwinters on live plant material so it's ok to compost leaves and stems but get rid of any affected fruit in case it survives in the pips.

Oospores can remain in the soil for several years.

This is more up to date & says;
"The presence of new strains in the UK means that the pathogen now has the potential to produce resting spores (oospores) in the affected plant tissues. The oospores are released from the rotting tissues to contaminate the soil. These resting spores have yet to be found in the UK, however, and little is currently known about their survival and their potential as a source of the disease. The investigations into oospores are continuing and more information may be available in a few years."

I've also had blight on some of my plants, so I stripped infected leaves and fruits, and then sprayed the rest with "Bouillie Bordelaise", a copper based fungus preventing solution. All seems fine (if you do not mind looking at BLUE tomatoes and leaves!). Good luck with your crop.

Thanks for that JungleJane - always the need to keep upto date with the latest news as nothing seems to stay the same for long nowadays.

I stand corrected, didn't know that. Thank you Jungle Jane. (Blummin heck, I've gone and composted a load of affected plants this afternoon).
