Default verticillium battle

We've had our hoop house plants diagnosed and the soil contains verticillium. Last year we did experiments in it using Actinovate and Terraclean as soil drenches in different beds. We would like to do the same type of experiments this year but now I'm wondering..... Will the drenches from last year still be in the soil? It won't help us doing the experiment if the soil is already altered from last years drenches. Does the stuff have a lasting effect or does it dissipate or break down in the winter? Anyone know about long term use of either product?

I do not know what is in Terraclean, but the bacteria in Actinovate die off
below 59F soil temperature.

Thanks for the help on that. I haven't been able to get any clear answers and we really need to know what we're dealing with before we lay out the study.

Terraclean is a mixture of hydrogen peroxide and paracetic acid. Both
react quickly in soils, and I would expect them to be down to pre-application
levels in a couple of days. This study on Perasan and Perasan-A (same
ingredients as Terraclean) has details:
http://www.envirotech.com/pdf/PAA%20...0in%20Soil.pdf

So I would expect no contamination with Actinovate or Terraclean applied
the year before to have any effect on this year's tests.

Val Miz - any signs of success with your experiments last year?

Default some interesting results

We just started looking into how to deal with verticillium in our soil last year. We used six different beds, a different treatment in each bed. One bed had two soaks of Terraclean ( one before planting, one later in the season),one bed had a mix of Terraclean and Actinovate, one a soaking of Terraclean alone, one a soaking of Acctinovate, one a control with nothing, and, unfortunately, one with , unknowingly to us, contaminated compost. The 2 doses of Terraclean produced the most weight of tomatoes( 37 pounds) and the Actinovate and Teraclean Mix produced the largest amount of eggplant (6.1 pounds) The rest of the treated beds produced alittle more than half of those weights, except, of course , the contaminated compost. The control bed produced less than half the weights for tomatoes .

Dice, I have read all the literature I can find on Natural Industries web site and didn’t see anything about the bacteria in Actinovate dying off below 59F soil temperature. Can you point me to your source for this info?

My soil is very close to that temp when I plant out here in SW Ohio and I certainly don’t want to waste any product.

Thanks,

I can try, but I skim so much stuff in the course of a search for information
about a problem that I may not have it bookmarked. (I see that I said
"53F" in a previous post. It could have been from some research on
verticillium in potatoes.)

This document says, "This biocontrol is effective at temperatures above
45F,": http://kentcoopextension.blogspot.co...1_archive.html

(I must have come across the "5[something]F" figure somewhere, but
I just noticed it in passing while looking for something else.)

The main question especially with Actinovate is does it go dormant at lower temperatures or is it eradicated? Boomer at Natural Industries who is a member of TVille would be the one to ask.

Question, did you inoculate your plants with mycorrhiza prior to and during plantout?

The Actinovate faq at Natural Industries says "above freezing", but
is that air temperature or soil temperature? It does not say.
