﻿562 
  Seventh 
  Annual 
  Report 
  of 
  the 
  

  

  I 
  find 
  the 
  \'ineyards 
  very 
  free 
  from 
  disease. 
  

  

  In 
  nearly 
  every 
  nursery 
  I 
  find 
  more 
  or 
  less 
  trees 
  scattered 
  through 
  

   the 
  hloeks 
  with 
  black-knot 
  on 
  plums, 
  wooly 
  aphides 
  on 
  apples, 
  

   scurfy 
  on 
  pears 
  and 
  currants, 
  lecanium 
  on 
  plums, 
  currants 
  and 
  

   some 
  varieties 
  of 
  ornamental 
  trees. 
  

  

  In 
  some 
  blocks 
  of 
  pears 
  I 
  find 
  psylla 
  quite 
  abundant, 
  which 
  

   gives 
  the 
  trees 
  a 
  black, 
  unhealthy 
  appearance. 
  There 
  is 
  also 
  con- 
  

   siderable 
  pear 
  blight 
  in 
  some 
  sections. 
  

  

  The 
  woolly 
  aphides 
  on 
  apples 
  is 
  very 
  abundant 
  in 
  many 
  nur- 
  

   series, 
  and 
  many 
  thousands 
  of 
  trees 
  have 
  been 
  rejected 
  and 
  destroyed 
  

   by 
  the 
  growers 
  this 
  fall. 
  

  

  One 
  nui'seryman 
  has 
  sent 
  some 
  boys 
  over 
  his 
  blocks 
  of 
  apples 
  

   every 
  week 
  during 
  the 
  latter 
  part 
  of 
  the 
  season, 
  and 
  put 
  a 
  little 
  

   kerosene 
  on 
  all 
  the 
  aphides 
  they 
  could 
  find. 
  This, 
  at 
  once, 
  causes 
  

   them 
  to 
  disappear 
  and, 
  as 
  the 
  result, 
  this 
  man 
  has 
  the 
  cleanest 
  

   blocks 
  of 
  apples 
  to 
  be 
  found 
  in 
  this 
  section. 
  

  

  I 
  only 
  found 
  one 
  nursery 
  in 
  which 
  scurfy 
  bark 
  scales 
  appeared 
  

   in 
  alarming 
  quantities. 
  This 
  was 
  upon 
  a 
  block 
  of 
  standard 
  pears, 
  

   and 
  I 
  had 
  dug 
  and 
  destroyed 
  about 
  300 
  trees 
  before 
  I 
  would 
  ask 
  

   for 
  a 
  certificate. 
  

  

  I 
  find 
  the 
  nurserymen 
  very 
  willing 
  to 
  destroy 
  any 
  trees 
  infested 
  

   with 
  any 
  of 
  the 
  above 
  dangerously 
  injurious 
  insects 
  or 
  diseases, 
  and 
  

   many 
  are 
  willing, 
  and 
  have 
  this 
  fall 
  fumigated 
  any 
  portion 
  of 
  

   stock 
  to 
  be 
  shipped, 
  where 
  I 
  have 
  requested 
  it. 
  

  

  ORCHARDS. 
  

  

  I 
  have 
  only 
  spent 
  a 
  few 
  days 
  this 
  fall 
  thus 
  far 
  in 
  the 
  inspection 
  

   of 
  orchard 
  trees 
  and 
  plants, 
  but 
  have 
  found 
  San 
  Jose 
  scale 
  in 
  

   every 
  one 
  visited 
  (five), 
  which 
  shows 
  that 
  this 
  dreaded 
  disease 
  has 
  

   been 
  widely 
  scattered 
  through 
  the 
  State. 
  I 
  did 
  much 
  orchard 
  in- 
  

   spection 
  last 
  winter 
  and 
  spring 
  under 
  the 
  direction 
  of 
  Mr. 
  G. 
  G. 
  

   Atwood, 
  and 
  his 
  report 
  covers 
  my 
  work 
  at 
  that 
  time. 
  I 
  have 
  no- 
  

   ticed 
  the 
  results 
  of 
  his 
  experiments, 
  and 
  hence 
  only 
  add 
  one 
  to 
  

   his 
  list.
