fusarium rot?

cajmSeptember 1, 2012

We grow Heirloom varieties, German Johnson,Mortgage Lifter, Brandywines and romas. The plants were doing well and I am thankful that I was able to harvest enough to can 14 quarts this season, but within 3-4 days, our plants, one by one, withered and died. Research suggests Fusarium rot. According to what I have read,I will not be able to plant in this field for at least 3 years and that this disease is prevalent in Heirloom varieties. Is there anyway to get rid of the disease in the soil without using chemicals so I can use the field next year? Is there anyway to make sure it doesn't happen again next year in a different field. Thanks, Connie M

Since Fusarium can't exist in the soil where the ground freezes deeply, there hasn't been much Fusarium IN NJ, although there are pockets of it. This past winter was a mild one so it would mean, if the spores survived, that you probably should have had Fusarium infected plants LAST season.

Most of the Fusarium in the northern climes is imported on tomato plants that were grown in more southern Fusarium areas and then shipped up north for sale.

What criteria did you use to make a DX of Fusarium as compared with other systemic diseases such as Verticillium and others?

So I assume there were no spots on any of the leaves?

If you're sure that it is Fusarium, and again, may I ask if your plants have ever had it before b'c it seems new to you and you say that ALL of the plants are going down one by one.

No, there are no chemicals that will rid the soil of the systemic diseases caused by either fungal or bacterial diseases.

There's another thread here which discusses what I suggest folks can do if folks have plants with foliage diseases, but I'm not too sure it would work well with systemic diseases, especially if a whole area such as you describe is contaminated.

Hope that helps at least somewhat.
