Nematode Control Failure - Page 5

Google shows Hanford HS with a street address down in Richland, WA,
south of there ("the Tri-Cities area", Richland-Pasco-Kennewick). But
there was a town of Hanford there at one time. It was probably closed
down when the nuclear research and plutonium production site started
up. It is listed in some Ghost Towns sites online:
http://www.ghosttowns.com/states/wa/hanford.html

When you search for Hanford, WA with Google Maps, the pointer is on
an open field north of the Tri-Cities. Just to the southwest of that pointer
you can see a bunch of buildings, tanks, holding ponds, etc that were
probably the actual nuclear production facility. (There is a vitrification
plant, etc, there now.)

Yes, that would be a pretty good bet for the most polluted site in the
country.

One last bit of thread drift, EPA fyi on the Hanford site:

Back to nematodes:

By a fairly circuitous route that began with me looking up something
unrelated in Wikipedia, I ended up reading about the Bambara Groundnut,
a relative of the peanut and a staple in sub-Saharan Africa:
http://en.wikipedia.org/wiki/Bambara_groundnut

Looking at the kind of weather and soils that it tolerates, it seemed like
it would be perfect for the soil and weather that Jack was describing in
2011 in NE Texas. Then I got to the bottom of the article and noticed that
root-knot nematodes were one of the pests that are known to prey on
the Bambara groundnut.

Since it is closely related to the peanut, I wondered if there were RKN
tolerant or resistant peanut varieties that could be grown on similarly
marginal land in similarly arid conditions. I came across this article:
http://www.plantmanagementnetwork.or...ment/rootknot/

I still do not know how the water requirements for peanuts compare
with the water requirement of Bambara groundnut, but the peanut
article did have some interesting observations on rotations to reduce
nematode populations and howing growing one of the RKN-resistant
peanut cultivars affects subsequent crops in rotation with it.

One of the things almost all South Florida gardeners have to deal with is RKN. It's everywhere. I don't know if this is practical for you, but I got this from the one of the big commercial growers in Homestead, FL. He solarizes the plot with a covering of black plastic left on for a month in the height of our 94 degree summers then plants in the fall like usual, so I tried it. It worked perfectly! Not one root knot. I have done it for 7 years now, an have never had the problem return.
The solarization cooks them!
