ave really tested only two varieties so far, these are the
Fodermaier and Wright. Both are very good, but we now consider Wright to
be by far the better of the two. It is somewhat hardier than Fodermaier,
nuts ripen earlier, and bears better with us. Fodermaier is also more
severely affected by the butternut curculio than is the Wright, some
years nearly all of the Fodermaier nuts have been destroyed by the
curculio.
GELLATLY has borne only one year with us, so we cannot form much of an
opinion on it. It appears to be a very good nut.
Crath Carpathian Persian Walnuts
Several of our seedling Crath trees have nuts this year. In all cases,
there are only a few nuts on each as our trees are still quite small. I
had to hand-pollinate the blossoms this spring; this resulted in a
rather small percentage of sets; then the curculio took a rather severe
toll, so we will have only a few of each variety.
In 1944 one of our seedlings bore 12 nuts. These were so good that we
have named the variety "Littlepage" in honor of the late Thomas
Littlepage, and are having it patented. We have published a little
booklet on this variety, and upon request, we will be glad to mail a
copy to anyone interested.
This is about all we have to offer at this time in regard to our variety
tests.
We have a problem which I wish to bring before the members of the
Association. It is that of controlling the butternut curculio. This
insect is very bad on butternut, heartnut and Persian walnuts, with us
it does not attack black walnuts or hickories. I fear that it is going
to prove hard to control, as the larva is of the boring type, being
found inside the green nuts, inside the new growth of the terminals and
in the fleshy part of the leaf stems. In these places it cannot be
reached by poisons. It appears that we will have to work entirely on the
adult beetles. These eat very little and seem to make puncture-like
holes, eating little outside tissue but mostly deeper tissues, thus
poison will probably have to be applied heavily in order for it to get
enough to kill it. D.D.T. is not effective against the apple and plum
curculio so probably will not be so against the butternut curculio. It
might be effective to apply a heavy coating of D.D.T. bearing dust under
the trees so that as the larva drop to the ground to pupate, they will
be killed while the adult beetle may be immune to D.D.T., it is not
likely that the pupa could survive in heavily imp
