You must be talking about possum grapes,since they're pea size;that's
too small for Muscadines.If you have some infected ones growing a few
feet away from your proposed vineyard,then it would be best to destroy
them.Anyway,wherever they are if you can,at least gather all the
infected berries and leaves and burn them.There's some possum grapes
growing up one of my neighbor's trees on the creekbank with leaf
phylloxera.Possum grapes are so common in Tennessee it would be
impossible to destroy all in the neighborhood.
But now since you do positively know there's a threat of black rot in
your area,might as well start stocking up on fungal sprays--I use
Mancozeb,Ferbam, & Captan.Benomyl is also recommended by the University
of TN for this area but hard to get. If a vine gets infected with Black
Rot,Nova is a good curative.Also I found some dormant lime/sulphur on
sale at Big Lots for $2.99 a while back. Nowadays you have to spray ALL
SEASONS,even while dormant...And you can't always depend on what the guy
at the Garden Shop says,too,they'll often sell you something that won't
work or doesn't apply to grapes if not careful.
