Hello i have two tomato plants and both have devloped brown spots on the lower leaves which appear thinner than the green part of the leaf i have never toms before and i am wondering if i have the dreaded blight or leaf burn cheers sorry cant get pics on
In the greenhouse or garden?
Unlikely to be blight btw
More than likely it is weather conditions-if the rest of the plant is healthy probably nothing to get too concerned about.
Italiophile- our tomato expert will probably pick this up at some point with words of advice
"Blight" has become a bit of a generic term. It gets applied to any leaf disease. There are only really two "blights" - Early (very common in the home garden) and Late (uncommon in the home garden). Most of the fungal and even some of the bacterial diseases have similar sorts of symptoms. It takes practice and a keen eye to tell them apart.
Anyways, brown spots can be fungal but a bit more detail would help. Are they simply spots? Or is there any sign of a "halo" around them?
This, for example, is Septoria Leaf Spot, probably the most common fungal problem in the domestic garden:
This is Early Blight, which rivals SLS for frequency in the domestic garden:
The identifier for Early Blight is those tiny rings you can see within the enlarged brown spots.
How exactly do your spots look, f&n?
Do you mean the affected leaves are darker brown around the edges? In other words, leaves with brown spots with darker brown edges?
