Vapam / Fumigant
Years ago when the EPA took Vapam fumigant off the market not for environmental concerns but because people used it inside the house and they became dead. It quickly sold off store shelves as it was the only 100% remedy for root knot
nematodes. Way back then on the family summer vacation to
mountain N. Carolina I took the back roads through GA. and
NC skipping the interstate all the way. I stopped at every
Ma & Pa Feed and Seed. Seems like they all had a dusty long
forgotten gallon or two. I managed to buy about 20 gallons
on that trip. I am down to 4 gal. now. I use only a little
every year and only for that years special heirloom tomato.
I have tried all the other remedies marigold,diamateous earth,high levels organic matter , heat treatment and nothing works like Vapam for killing our old enemy the root knot.
Well,that is my story and I am sticking to it.
