Tomato varieties resistant to blight

Post  butterwhat on 3/17/2015, 10:39 am

I have terrible problems with blight on my tomatoes every year.  Last year I learned about keeping the plants pruned and staked, and this year I will be keeping the soil covered with newspaper (any suggestions on other materials?). 

I've noticed that some varieties of tomatoes seem to do better than others, although they all end up with the blight eventually.  Can anyone recommend some tomato varieties that tend to do better against blight than others?

Last year my green zebras fared the worst, and the Brandywines hung in there the longest.  I like to grow one large slicing variety, a paste variety, two that are a different color than red, and one or two cherries.

Thanks!

Most seed catalogs will identify tomato varieties that will offer a degree of blight resistance, usually hybrid tomatoes.

I have early blight every year also.  This year I am trying Mountain Merit Hybrid, Red, Determinate, 75 days.  I don't usually grow a determinate but I am trying to defeat the early blight so I will try it this year.

Windmere grew Mountain Magic last year so maybe he will chime in with his results.  I think thinking  Mountain Magic is a cherry tomato so I decided not to plant that one.


There are also fungicides that can help protect them from getting early blight.  They won't cure them but can help prevent EB.  One fungicide that is recommended is Daconil.  That is not organic and I don't know its effect on pollinators.  If you are organic, then a copper fungicide might help.  I keep saying I will start spraying as soon as I plant out my tomatoes, but I never do.  I hate spraying anything on vegetable plants.  I might do an experiment this year to see if these work and just stop spraying when fruit sets.  Apparently you have to spray every 7 - 10 days and after a rain.  Too much work and too (maybe) harmful to the environment.

The copper, I have found, does work, if you apply by following the label instructions.
It can be challenging to have discipline regarding preventive care in the garden (and elsewhere in life). With repeating events, like spraying once a week, I can usually set an alarm in my mobile phone to remind me.
