THE GREEN PEA LOUISE.


During the past week We have
cent out two circulars, numbers Z
and IL, in reference to the Destruct-
i've Green Pea Lonse injuring peas
in this aud other states, and We
find nov that with the prevailing
conditions in various parts Of the
State that il 10 necessary for as to
send out still another circular on
another topic giving special In
stpnctiens - fasmera Cor lian8line
this same pest where it has attacked
clover.
The frst report OF serious dam
age by this insect in clover came to
as from Mr.. f. 81. Wills, Of Bel
Alton, Charles county, who report
ed that fully forty acres had been
ruined By the insect.
Examination of other fields of
clover in various other sections of
the State also revealed the fact that
this pest was doing considerable
damage to peaches, and to red and
scarlet or crimson clover over q
wide area. We found the pest abun-
dant in limited area in O clover field
of +. P. Roe and Bro, Greensboro,
Caroline county. In both Charles
and Caroline county fields we found
that the louse was being attacked
BY a fungus disease, and many Of
them were being destroyed. In one
instance fifty eight dead lice were
found on the single lobe Of clover
leaf.
With this condition we feel GER
tain that the disease has destroyed
large number Of lice; bat at the
present time they are still abundant
in certain sections, doing much
damage to clover. Mr.. Charles T.
Day, Of Boyd's, Montgomery Co, i,
Nd, writes me, May 18th as fol.
lows: "On going to my clover
field situated on the back part Of
my farm; few days ago i found
six or seven acres completely de-
stroyed BY an insect that is appar-
emily new in this section. will
send You to-day BY mail q box con-
tanning clover infested with insects
for your examination and report.
Kindly let me know what they are
and how to prevent their spread
into other fields il it can possibly
be done at this time. A large num-
Der Of farmers IN this section are
very uneasy about this matter"
In view Of this condition of af-
fairs, and from personal otserva-
tions in various sections where this
insect is confined in clover fields in
local areas, / would advise farmers
to plow down without delay all in
tested areas; harrow the land we'll
and roll it afterwards. This will
prevent the rapid spread of the
species over these areas of infesta-
tion, inasmuch 90 the insect spreads
rapidly, as soon as the plant begins
to decline. This louise 10 represent
ed BY both winged and wingl,s %
forms, the winged forms predomi-
mating when there is not sufficient
vitality in the plant to furnish food
for the colony. At the present
time they attack, blight, and spread
rapidly into adjoining fields; the
destruction therefore Of these in
tested districts without delay, will
prevent to great extent the devel-
opment and spread of this peat,
which must necessarily follow where
the clover 10 allowed to shrivel and
die on the field, such q condition
would necessitate the flight of the
insects to other fields for feeding
purposes. As stated in our pre-.
vious circulars where this insect in.
tests peas especially where they are
planted in rows. We suggested the
brush and cultivator method. A
boy should precede the cultivstor
and brush the peas backwards and
forwards knocking the insects upon
the ground the cultivator following
Immediately. By this system 3
very large percentage Of the insects
are destroyed.
We also desire TO impress upon
farmers the necessity Of keeping q
close watch upon clover fields in
the vicinity Of pea fields and the
immediate destruction Of any in
tested area, 90 noted above. We
also desire to impress the fact that
with the present prevailing condi-
tions most Of these insects can be
destroyed by simply brushing them
