TomaTOES aNp POTATOES. 
Buossom Enp Rot (Macrosporium Tomato, Cooke).—The 
rotting of the nearly grown or ripe tomato. Dull dark green spots 
of a velvety appearance show at first. These slowly enlarge, and 
the tomato rots entirely. The fungus is a wound parasite, gaining 
entrance into the ripening fruit through minute cracks. It feeds 
on the tissues under the skin, thus causing a little sinking below 
the surface of the healthy part of the fruit. Green stable manure 
is said to favour the disease, causing the fruit to crack. Bordeaux 
Mixture keeps the disease in check. 
Rive Ror (Glaosporium fructigenum, Berk).—Commonly known 
as Ripe Rot, and often destructive to ripe apples, pears, peaches, 
and grapes. Concentric mark- 
ings with no velvety appear- 
ance, as in the case of Black 
Rot, distinguish this disease, 
the skin remaining for some 
time glossy, though discolour- 
ed ; the attacked area is flatten- 
ed. When the pustules break 
out the spores give to the sur- 
face a granular appearance. 
Preventive.—The small = 
cherry and plum tomato arenot Ripe Rot (Gleosporium fructigenum, Berk.) 
attacked. Trainingthevineon Agricultural Gazette, New South Wales. 
stakes or trellis, so as to give 
the fruit plenty of light and air, is usually useful, as the Black Rot 
is more active in a damp atmosphere and near the ground. Burn 
diseased fruit and vines. Drain if necessary. Never use seeds 
from diseased tomatoes. Alternate crops. 
Remedy.—Spray the young vines with Bordeaux Mixture or 
sulphide of potassium, and then periodically every few weeks— 
especially the young fruit. aA 
Lear Rust (Cladosporium fuluum, Cooke).—This~ disease 
spreads with great rapidity. It is caused by a fungus which forms 
rusty brown patches on the under-side of the leaves. These patches 
consist of closely packed clusters of coloured conidiophores. As 
these patches spread the leaf becomes yellow and wilted, the mar- 
gins curl, and the leaves shrivel and die. Bad drainage and moist 
situations favour the growth of the fungus, which requires plenty o} 
moisture. Trellising, by lifting up the plants into a drier atmos- 
phere, lessens the liability of attack. Spraying with Bordeaux 
mixture or with sulphide of potassium (liver of sulphur) will hold 
the disease in check.
