THE PEAR 



127 



Inquire whether pear trees sprayed with fungicides are 

 injured by these diseases — leaf -blight and pear scab. 



Insect Enemies 



Look for pear leaves which have had the surface 

 eaten off, leaving the network of veins to show. In 

 summer the little pear slugs that do the damage are 

 likely to be found. 



See if you can find pears showing the crescent marks 

 of the curcuho ; or those infested by codling moth larvae. 



Look for bark-lice or scale insects on pear trees.
