Re: Foliar nematodes

Bob Solberg is quoted below,

"You can "cook" the hosta clump  or a piece of the plant. This will kill the
nematode eggs in the plant. To cook, use only dormant hostas, I do this in
February, about a month before emergence. You can do this in the kitchen
sink with tap water and a good thermometer.The proper cooking time is
somewhere between 120 degrees F for 20-25 minutes to 130 degrees F for 10

Try doing different pieces of the same  hosta at several bracketed temps and
times. The lethal temps and times for
hostas are very close to these "recommended" ones, thus you will kill all
the roots on the hostas and maybe the whole plant. So pot them up and regrow
the roots and put the plant in the ground in August."

The above is  quoted from a message from Bob Solberg, Green Hill Farm.
