Tomato blight! Arghhhh





After days of rain and only to shortest of visits to the garden, Thursday was finally a nice enough day to inspect the vegetables. Sadly one of the larger pots is showing signs of the dreaded blight. So far I have found 3 fruits with softer, paler tops which if left would certainly go mouldy. The stalks had shiveled up too.

Im now wondering if some other tomatoes have it as well. These others have developed dark brown tops at the stalk. There is no sign of mould and the stalks look fine. Ive left them on the plant to see what happens.

All thats needed is a good dry spell. Maybe September may bring one.

On closer inspection later, there is far more mould infection than I first thought. Each day I look at the plants and each day there are shrivelled leaves, fruit with soft pale tops and Ive also found that some main stems are dying. Ive just removed one stem were the leaves were wilting. It wasnt due to lack of water to the plant but the stem had completely die half way down. Squeezing that part it was hollow inside. Photo 2 shows it eating away at the stems, creeping nearer to the tomatoes.

Photo 1 shows the soft pale tops to a couple of tomatoes. The stem has died showing a pale growth.

Photo 3 shows the dark brown top. Its hard and dry and only affecting the variety that was supposed to be blight resistant. It may have a different desease.

Photo 4 shows the shivelled leaves. This has occured on all three varieties and can appear overnight.
