MISSISSIPPI 
By R. W. Harned and Oliver I. Snapp 
The San Jose scale was first introduced into Mississippi and other 
southern states in 1891, and since has been allowed to spread and 
increase without any attempt on the part of deciduous fruit growers in 
this region to check its progress, until 1917, when it was safe to say 
that from 85 to 90 per cent of all deciduous fruit trees in the state of 
Mississippi were more or less infested with the pest. 
The terrible devastation of Mississippi orchards by this pest, and 
the decided lack of a general knowledge of spraying throughout the
