The causal organism of Bacterial Fruit Blotch is Acidovorax Avenae Subs Citrulli. This bacteria may be seed borne, but infection may also occur from many types of secondary sources before or after planting. The most pronounced spread of Bacterial Fruit Blotch occurs in greenhouses, where optimal conditions for the spread of the disease occur.
In young seedlings, the disease can cause water soaked lesions to appear on the leaves of the plant, and in some cases on the stem as well. They will change, turn nektonic with yellow halos around the necrosis, possibly appearing on the leaves during any stage of plant growth. However, the real damage from this disease occurs after fruit set, when these lesions appear on the fruit. The fruit will begin to decay and make it unmarketable.
While Bacterial Fruit Blotch can be a devastating disease, early detection can help minimize losses. Research has shown that the early detection of the disease, followed with timely applications of copper based fungicides, can greatly reduce the spread and subsequent damage caused by the disease.
Too date, their is no way to prove if this disease is present in seeds, and their are many other possible sources for
Our seeds are from growers who have tested for this disease by growing isolation lots from seeds and inspecting for the disease, which is the only known way to test seeds for the disease at this time.
We have talked to many watermelon seed producers and it appears that this disease is almost always found from transplants grown in warm, humid greenhouses. If you can direct seed into the garden, rather than starting seedlings in the greenhouse, you should.
