MILDEW  IN  STRAWBEERIES  (W.  R.  R.).— From  your 
description  we  consider  the  plants  are,  or  w’ere  last  year,  affected 
with  Strawberi’y  leaf  spot  disease,  Sphaerella  fragariae,  this 
fungus  frequently  attacking  the  leaves  of  cultivated  Straw- 
herries,  and  is  widely  distributed.  Small  spots  first  appear  on 
the  upper  surface,  and  as  these  continue  to  increase  in  size  for 
some  time,  and  ran  into  each  other,  large  blotches  are  often 
formed.  The  central  part  of  each  blotch  changes  to  a  pale 
grey  (almoist  white),  and  is  bordered  by  a  reddish  line.  On  the 
white  central  spots  appear  white  tufts  of  mould ;  these  con¬ 
stitute  the  conidial  condition  of  the  fungus.  Later  in  the 
season  minute  black  points  appear  on  the  white  iDatches,  and 
these  are  fhe  rest  spores,  or  higher  stage  of  the  fungus,  known 
as  perithecia,  and  contain  spores  produced  in  asci.  Minute 
sclerotia  are  also  formed  in  the  fading  leaves.  The  ascopheres 
and  sclerotia  germinate  the  following  spring,  and  the  spores 
thus  produced  start  the  disease  again.  In  bad' cakes  the  fldSy^r 
stems  as  well  as  the  leaves  are  affected,  and  if- badly  diS'eashd 
the  crop  is  materially  prejudiced,  if  not  completely  Tfisfe'. 
Besides,  the  plants  become  so  weakened  through  loss’ uf  leaves 
that  they  are  comparatively  worthless  the  following  season. 
As  regards  preventive  means,  little  has  been-  done  in.  this 
country,  but  experiments  in  the  United  States  show*  that  tire 
disease  can  be  checked  by  spraying  with  Bordeaux  fnixture..  In 
cases  Avhere  the  disease  has  existed  previously,  spraying  should 
commence  when  the  leaves  unfold,  and  be  repeated  at  intervals 
of  ten  days  or  a  fortnight,  until  the  flowers  appear,  after  which 
the  Bordeaux  mixture  cannot  he  applied  without  spoiling  the 
crop.  In  the  United  States,  where  the  disease  is  often  very 
severe,  Professor  Trelase  advises  the  following  treatment :  As 
soon  as  the  frait  is  gathered,  cover  the  dry  tops  with  a  light 
coating  of  straw,  and  set  alight.  This  is  harsh  treatment,  but 
the  experience  is  that  evei^mne  who  has  tried  burning  over  a 
Strawben-y  bed  has  been  surprised  by  the  vigorous  and  healthy 
a.ppeara.nce  of  the  new  foliage,  which  soon  unfolds.  The  treat¬ 
ment,  of  course,  is  not  applicable  to  St.  Antoine  de  Padue  and 
other  varieties  that  fruit  in  August,  September,  and  October. 
Nevertheless,  it  is  clear  that  the  ascigerous  form  of  fruit  and 
the  sclerotia  of  the  fungus  live  over  the  winter  in  the  old  leaves, 
and  the  destruction  of  these  by  burning  is  the  most  certain 
method  of  preventing  the  recurrence  of  the  disease  in  the 
following  season.
