Tomato plant disease question

[UK SAINTS]

I have noticed these brown spots along the edges of my tomato plants.

I am attaching a few pictures.

I'm thinking that it may be early blight, but wanted some other opinions.

Thank you

looks like blight to me.

just uprooted all my Roma Grape Tomato plants due to blight. Heavy rains and high humidity and it was like overnight. I tried to clip the lower dead branches, but didnt help ( since I didnt treat properly )

But from early Arpil til Mid July, the three plants produced well over 400 Grape Tomatoes. At one point, we were giving vats away because we couldnt possibly eat them all.

but your third pic looks like mine did when I started clipping. The first two, you can probably stem the damage thru pruning and treatment.

I plan on paying more attention next year to the plants since once it takes hold, very quick to turn a healty 5 ft tomato plant into brown/yellow throughout.

Thanks for the reply, efil4stnias.

In addition to pruning the plants, what else would you advise for treatment?

This happened fairly fast as we have had extremely high humidity and heavy rains. Much of my garden is clay. This is my first year and I was only able to till 3-4 inches, and I also added much compost.

But the first two pics show the blight on a potted plant, which I would think gets decent drainage.

Any advice appreciated...

drainage, per se, isnt the problem. Blight is a fungus. I didnt know, but its also "transferrable"; in that you remove a blighted stem, then touch a good one, you've just infected the good one.

If you want "natural/organic" way:

Baking Soda Spray: For anthracnose, early tomato blight, leaf blight and spots, powdery mildew, and as a general fungicide. On plants that already have powdery mildew, hose down all infected leaves prior to treatment. This helps to dislodge as many of the spores as possibly to get better results. Use as a prevention or as treatment at first signs of any of the diseases.

To make: Mix 1 tablespoon baking soda, 2 1/2 tablespoons vegetable oil with one gallon of water. Shake this up very thoroughly. To this mix add 1/2 teaspoon of pure Castile soap and spray. Be sure to agitate your sprayer while you work to keep the ingredients from separating. Cover upper and lower leaf surfaces and spray some on the soil. Repeat every 5-7 days as needed.
