Generally, the scab may be controlled by three treatments if 
they are made promptly and very thoroughly. These three, as 
numbered above, are 3, 4 and 5. Winter treatment against the 
scab is not recommended. See page 404. 
For treatment of lice or aphis, scale insects, rust, sooty blotch 
and fly speck consult the special discussion of these subjects on 
previous pages. 
APRICOT DISEASES. 
FRUIT ROT. 
The ripe rot of apricot fruit is due to the same fungus as that 
causing ripe rot of cherries. It is discussed on page 420. 
LEAF-SPOT. 
(Cylindrosporium padi Karst.) 
The fungus which causes apricot leaf-spot also causes a spotting 
of the fruit. When the leaves are attacked the diseased part 
usually drops out leaving a clean cut hole. In severe attacks the 
foliage is riddled with holes. The same fungus also attacks the 
foliage of plums and cherries. For the treatment, see plum leaf- 
apot, page 454. 
GUMMING. 
See discussion of the gumming of stone fruits, page 438. 
APRICOT INSECTS. 
CURCULIO. 
This insect does great damage to apricots by causing wormy 
fruit. Frequently a large part of the crop becomes infested and 
drops unless measures are taken to kill the beetles before they 
deposit their eggs in the young fruit. This is best done by jarring 
as recommended in the discussion of this insect under the head- 
ing “ Plum curculio.” It is very important that the jarring be 
gin as soon as the fruit sets, because the curculios do much injury 
to the very young apricots.
