I have a patch where the pumpkins always get some type root and stem rots. I would like to know what some other growers have tried for soil borne deseases.
Would most of you recommend Subdue Maxx (which is the same as Ridomil Gold, right?) Or are there better ones out there? And finally, does it have to be in a granular form or do other formulations work just as well when soil applied?
Thanks

I am pretty new at this but have been looking into BioGrow Endo Plus from Joel Holland's site. It is not that expensive. There is a catalog posted on this site. Anyone who has used it please jump in.

I use an industrial version of immunox. The main ingredient is myclobutanil. we use overhead misting to keep our patch coll so we tend to have very high humidity levels and we have not had any root or stem rot...this is also a systemic so it hangs around for awhile....

Tremor, Any comment?

Subdue Maxx is useful against Phytophthora & Pythium only.

If the root rot you have encountered is either Fusarium or Rhizoctonia then Subdue is of no use.

We need more specific causal pathogen data.

Whatever is affecting these plants in this patch goes to work pretty early in the season, before any friut is set. The plants usually are stunted some and very easy to pull out, like they have a very small root system. Also it seems to affect the the stumps of the plants. I don't know if this helps any, Tremor?
Is there a more broad fungicide that would also work on Rhizoctonium & fusarium?

A few questions:

How is the soil in this area?
Has it been well amended with organic matter?
What other crops have been grown in this location?
How is the drainage in this area?

It is good soil in this area, but maybe a little on the heavy side and it has had some manure put on it the last few years. I would say it has adequate drainage. It has had AG's in it for the last 3 years. However this fall we planted winter wheat in it. I thought maybe this could help brake the cycle of diseases?

For unknown problems with several possible causes one might be enlightened to read the catalog and possibly discuss a natural fix.

Fertrell has two products possibly worthy of consideration. One is called Storox. The other is Oxidate. Used together they support each other by causing each to be more effective as I understand the program. They have had great success while working with other growers, with more than a few, very pleased customers.

They are working on the principle that the pathegons are always there. These past two years have been the dickens to deal with. No one denies this! There approach is to supress by supporting naturally stronger healthy plants as well as possibly supressing the funi directly. They or no one else can address the airborn very well.

Serious aerobic tea applications done correctly have shown much promise. This is a whole other approach which shows much promise while resisting the airborn milldews. This however does not seem to be your suspected problem area.
