pests which can be attacked by spraying; in fact, with the 

 exception of the gypsy and In-own-tail moths, they are pretty 

 free from leaf-eating pests, bnt the cane borer which does 

 considerable damage on old plantations is a hard insect to 

 fight and can only be controlled by removing the canes which 

 show signs of dying after they leaf out. Spraying for leaf 

 rust with Bordeaux mixture is as yet the best iifethod of con- 

 trolling this rather serious pest on blackberries and raspber- 

 ries, but in very bad cases it is far cheaper to cut the plants 

 down entirely and start fresh in new soil and with new plants. 

 Root gall is more or less serious on raspberry plantations, and 

 here, again, the site should be changed and new plants free 

 from this pest planted. 



Anthracnose, a common disease among raspberries and 

 blackberries, can be controlled by spraying with Bordeaux. 

 In fact, many troubles with our bush fruits can be controlled 

 by this excellent spray material. One very important factor 

 in the control of diseases and insects among these fruits is 

 cleanliness. The ground should not be allowed to grow up 

 to weeds and grass. Fence corners and walls near the planta- 

 tions should be kept clean, for often our worst pests, both in- 

 sectivorous and fungicidal, live over winter in places where 

 refuse is allowed to collect. 



With the strawberry, spraying should be done to control 

 leaf blight, and early sprayings just as soon as the new leaves 

 appear will do more good than when the blight appears ; in 

 fact, spraying in the very early spring the dead foliage of the 

 previous year's growth will often check an attack of leaf 

 blight. 



There are very fev/ leaf-eating insects which attack the 

 strawberry, with the possible exception of the cutworm, which 

 can be controlled by spraying with Paris green. Probably 

 the worst pest of the strawberry is the common white grub. 

 This insect attacks the roots of the plants, and does great 

 damage before its presence is noted. Practically the only 

 way of controlling this pest is by rotation of crops, so that 

 strawberries do not follow strawberries more than two years 

 on the same land ; neither should they follow potatoes or 

 clover.
