Tomato Disorders

Good morning and I hope you have a great day .  I have returned from an enjoyable camping trip in the mountains as well as family time at Disney .  The food that I processed with my new freeze dryer from HarvestRight .


920x60-2 It was easy and light to transport and delicious .   I enjoyed every minute but when I returned I found that some of the tomato plants in my garden needed some attention.  I did some home work and will share some of the things that I learned .

Diseases and Disorders are classified as two separate malfunctions in development .

I had to deal with disorders .  Disorders usually relate to growth conditions and do not spread from plant to plant .   The situations that need to be adjusted  for disorders are usually because of growth conditions such as soils, planting practices, and weather.  Blossom end rot , fruit cracks and uneven ripening can occur .  In my case it was the weather ,(too much rain), after a long hot dry spell .   I had fruit cracks and uneven ripening .

Diseases often express themselves as wilting, leaf spots , blight , and other fungal diseases .

Wilts are classified in this way , mid-day wilting occurs because of the plants inability to absorb water to its stems because of high temperatures during the day .  The plants cannot keep up with the water loss.  This is temporary .

If the plant does not respond to additional watering then we can assume that the plant has a fungus.  This fungus can spread to other tomato plants and sometimes can even survive winter .  The wilt fungus is first identified by a yellowing of the bottom leaves.  The leaves will dry up and fall off and will continue to progress up the entire plant .  It can involve the roots also.  The only thing that can be done is to dig up the plant and dispose of it , (not in your compost ), and treat the soil for fungi .  This situation , if soil generated ,  can also be the ruination of other crops such as potatoes , melons, spinach, and peas for up to 3 years . Treat the soil with a fungicide or replace the soil . A non susceptible replacement crop would be cabbage ,broccoli , beans or carrots.

Leaf Spot disease can occur when over watering .  Space plants far enough apart so they do not touch each other .  The free moisture on the foliage should be allowed to dry more quickly so a fungus will not develop.  The appearance of Leaf Spot is a small water soaked spot on the leaf that expands and becomes semi circular.  It will then become grayish white in color with dark edges.  This fungus can be treated also with fungicide prior to symptom development to protect foliage and fruit.

Early Blight can affect seedlings but is mostly common in older plants .  Dark brown spots with darker rings on older , lower leaves .  Plants could become defoliated .  Poor soil conditions as well as the need for proper drainage ,  and also high moisture conditions and even drought .  If the fruit is infected it will appear at the stem end and develop into black shriveled areas.  This disease can also be treated the same way as Leaf Spot .

I have also an experiment going on with applying to some crops a new ,(to me) ,  type of fertilizer that I use.  I found that Alaska Fish Fertilizer , available on Amazon can create a tremendous difference to the development of the produce that I have planted .  Yay  !!!  Love Grandma Jean
