On a couple of my plants the stem seem to be darkening in places but the leaves are ok, is this blight , they are producing tomatoes , where does blight first start.

was talking to one of the men at the allotment and he said that for some reason that where my plot is and some surrounding mine always seem to get the blight first before the rest of the allotment.

Marion, You're determined to get blight, aren't ya?
"Late blight (Phytophthora infestans)on tomatoes is very similar to the disease that attacks potatoes. So keep tomatoes well away from potato crops. Look out for it in the warm, moist weather of mid to late summer. At this time, wind-carried spores spread the disease very quickly. On the stems, the first signs are large, dark-brown spots, which can spread and kill the plant. Similar spots form on the leaves, although they may be lighter or grey in colour. It takes very little time for the leaves to be covered, after which they wither and die. It also affects the fruits, which go a red/brown marbled colour and become inedible."
