Pictures of tomato blight experiment so far

[GrannieAnnie]

 The plastic is a covering over three tomato plants- first rendition blew down but second seems to be holding despite flimsy supports; Two pictures of the good leaf coverage down low without blight on the three toms under cover which were: Better Boy, Stupice and Black Krim.

The last picture shows leaf damage on the plants exposed to the dew and rain. Many have had the lower leaves removed but the blight is appearing higher up on the exposed plants.  It is too early to state definitively the results of protection from moisture but it may make a difference.  We'll see.



Below picture not very clear but the blight is moving up the plants exposed to wetness. This plant has  had some lower leaves removed already and then sprayed with copper but the leaf damage continues.

Here is a follow-up on my mini-experiment using a plastic covering (see previous picture) over three tomato plants to protect them from rain and dew and blight:

They produced right up to frost whereas other plants (20), of the same types, grown in the open and exposed to everything did not perform well and many lost their leaves weeks earlier.

Another factor might be that they were slightly shaded by the plastic which wasn't quite clear, but I don't know how to separate out that in a trial next year.

I was also hoping the covering would protect them from frost. That DIDN'T work and they died with the second light frost.

Next year I'll try to cover more plants.

After suffering blight the previous two years I had much the same setup this year covering the tomato plants. I did how ever spay them with the first blight warning but only the once as of course it did not get washed off the leaves.

They finally succumbed to blight in early September after a period of daily blight warnings for a fortnight.
A great improvement on previous years though

As skeptical as I was about this I grew my toms with a set up like yours GrannyAnnue this year and have to say it worked for me.

When the blight alerts came and plot holders were spraying theirs I was itching to do mine as I so didn't want blight again this year.  But with all eyes on me I didn't dare.   Other plot holders had the blight and I picked for a good 2 weeks after they had lost theirs.  In the end I decided to cut my losses and didn't leave mine in as I didn't want to have to remove them from the site, if they did get blight so I stripped them all and composted the plants.

I did have blight at home in the ones I had grown on the patio.

Still can't work out how it stops it as my sides and each end were open but I'd recommend it to all.

Many plot holders on our site are going to do it next year.

As I've said before I grow mine under the roof canopy of our summerhouse and have done this for the last three years blight free.
When I grew them on the lottie they were blight wiped after 3 weeks of cropping as were most of the other lottie holders, except the Italians who, copper spray to deaf long before any blight warnings, they almost glow in the dark, like something out of Fools n Horses.    ;D ;D ;D
