He Makes Another Report ON the
Vine Disease.

Vine Disease.
In report No. 80 was given q descrip-
ton of certain vines at Florence, which
had been treated by cutting back the
canes and introducing benzine into the
circulation, by pouring it into holes bored
in the crown of the vine; this had been
July 18th to the middle of August last.
During the past month the vineyard was
again visited, when the vines were all
found to show signs of disease, though
none Of them showed 30 much
as the surrounding untreated vines; nor
was the amount of the disease the same
in each vine, those vines which had been
treated earliest showing most disease.
From the appearance of the vines it
would seem likely that had the treat
ment been continued, the vines
might have recovered. 1t is GER
tain that, for a time, the disease
was checked, and healthy growth was
induced. Some vines here, which had
been treated in a similar way, Report
No. So, have also given results like those
obtained at Florence, though it must be
remembered that hot spell Of consid.
cradle severity Immediately followed the
treating of the vines here, and this seri-
ously interfered with the success of the
experiment.
In order to better test the above treat
ment, as well as some other suggested
remedies, fresh vines have been set out
in the experimental dollhouse, the
vines originally placed there last
winter being taken out, with a
few exceptions. The vines first
planted in the. hot-house consisted OF
rooted vines and cuttings, obtainsd from
this neighborhood, and from Orange,
and included the following varieties,
viz: Mission, Muscat, Grenache, Carig-
nan, Grosser Blauer, Folle Blanche,
Lenoir, Burger, Black Malvoisie, Ries-
ling and Mataro, and several of these
were known to be diseased when
planted. These all came out well,
and, with the exception of several light
attacks of mildew, showed no sign of
disease until March, when few sus-
picious-looking yellow spots appeared
on the Missions, and on q wild
vine. At this period the vines were
literally dressed with the powder
known afterwards as Ongerth's
powder. This powder had been applied
before the yellow spots appeared, IS well
as afterward, it being always applied at
the first appearance of mildew. OF the
cuttings; thirty-six were Mission canes.
These were planted in nine rows of four
canes each. Two canes in each row
were untreated. The other two
were treated with various substances,
both in powder and solution, differing
more in the amount than in the kind
of the ingredients used in each. The re-
mainder of the cuttings of Black NAL
Nearly all Of these cuttings started by
the end Of April. The house was full
of vines, almost too full for the good
health of the vines, and by June the
growth had increased to such an extent
that the crowding Of the plants was in
ducing sickly growth. Quite third OF
the vines was then taken out.
After the end Of April the vines were
practically left to themselves, being pur-
possly neglected, with the exception of q
little water being given at intervals. At
the present time, three Mission vines
which were diseased when put in now
show no sign of sickness; three
Muscats and one Burger show q
very little disease, and three Mission
cuttings, which were dressed whom
put in, do not show any disease. All
have made large growth, many of the
cuttings having canes from ten feet to
fourteen feet in length. Almost all the
cuttings, both dressed and undressed,
made q start, out by October it was
found that, of the Mission cuttings.
nearly every undressed cane was dead,
whilst of the dressed cuttings, all but
two were alive and vigorous. All the
rest of the cuttings had made large
amount Of growth.
As the vines have practically ceased
growing for the present year, it may be
well to notice the present condition Of the
vines In this locality which have been
treated for disease. In reports No. 20
and 80, attention was called to the bene-
fits which had followed the use of the
so.called Ongerth's powder. As was
stated in the above mentioned reports,
three applications Of the powder were
made, and there is no question but
that good results followed; the disease
was checked, and . new and healthy
growth was produced. This state of things
continued until the hot weather set in.
In July the first hot spell was expert
enced, which threw back the vines con-
