al Forest have been eaten off by rab-
bits SO severely that 81 per cent of
them will die this year. White
spruce planted by the state near
Cusson showed So per cent damage
and over half sure to die. AS for
the Superior National Forest, in a
plantation of Norway pine in which
80 to 80 per cent of the trees were
living in 1913 less than per cent of
them can now be found at all ex-
cept as dead stubs killed by the rab-
bits. The destruction has been the
heaviest in brushy areas and in the
state game refugees where the rab-
bits are most abundant.
Poison Bait, bitches Will Halt
Army Worm The army worm,
which is doing enormous damage to
field crops in Ohio, Indiana, and Illli-
nois>apd has invaded sections of Wis
cousin and Iowa and is now migrating
northward in the last named state,
can be controlled, says A. G. Ruggles,
entomologist at University Farm, by
the use of poisoned bait and the dig
ging of trenches. The worm is a
close kin of the cut worm and feeds
chiefly at night. Two generations
are usually produced each season,
but in this latitude the second genera
ton does little damage.
c. E. Nickel, entomologist with the
university's agricultural extension
service has been in Chisago county to
give demonstrations in the use Of
poison bait in killing glasshoppels.
"a Nv WOO IciIo bnpx,or Tho
same species which dailagei crops
last year, is at work again this year.
TIE warriors are vo ;sLious feeders
ard usually clean up about all veg
etation as they go.
Walter Carter, another university
station entomologist, is also giving
demonstrations in spraying alfalfa
fields to control the blister beetle.
This beetle is of slate-gray color and
about a half inch in length. 1t is fond
of all kinds of legumes, but especial
ly of young alfalfa.
'Hort" Society o. KS the Name
of Latham-That the Latham and
Redpath raspberries are identical ex-
cept that the latter is more free from
mosaic disease than the former is the
finding of George M. barrow, fruit
expert of the United States Depart
ment of Agriculture who has been
conducting an investigation at The re-
quest of the Minnesota State Hort
cultural Society. The executive CO NJ
mittee of the society has accepted the
report and the use of the name 'Red-
/ path will hereafter be discontinued.
-. y, Winter, Of the nursery and or
chard inspection service, University
Finn, has been investigating The sus-
ceptibility of the two strains and has
found there are some fields reason
ably free from mosaic. Careful
roe'l eng OF these fields will provide
disease-free stock for propagating
pui oses.
Mosaic free stock must be recured
by all nurserymen and others intend
ing to propagate plants of the Lat
ham raspberry for sale," says A. G.
Ruggles, state entomologist. "Mosaic
lis a dangerously injurious disease
and as such will prevent nurserymen
from securing certificate of inspec-
ton. Growers will be given oppor-
tunity to propagate disease-free
stock.
"Some nurserymen have been buy
ing fields of raspberry plants which
have not been inspected by this de-
partment at ALL. Knowing that mo
sale disease is the cause of the run
ming out of raspberries, this practice
will now be conslf cred much more
serious than in the last and, if con-
tinued, viii result in the cancellation
of the certificate OF nursery inspec-
ton"
