sucking the nectar therefrom. It flies usually toward evening at 
dusk. Usually the larvae are not in sufficient numbers to warrant 
spraying. Hand picking will keep the pests in check. 
Lear Spots: A number of leaf spots occur on tomato, but 
they have not been serious in this state. Spraying with bordeaux 
will prevent them, if begun about ten days after transplanting and 
continued at intervals of about two weeks. 
Potnt Rot: The point or blossom end rot causes great damage 
in dry seasons. It appears on the blossom end of the fruit as 
sunken, brownish spots which may increase rapidly in size until the 
entire fruit is rotted. The cause of the disease has not been fully 
worked out, but it is known to be most prevalent on light soils dur- 
ing hot, dry weather. Spraying is of little value; sub-irrigation 
gives some relief. 
Ripe Ror: This causes the black rot so common on the ripe.

tain extent. The vines should be carefully trained so as to permit 
of sufficient aeration.

SPRAYING MACHINERY. 
.An individual may understand thoroughly all about insecticides 
and fungicides and their application, and yet unless he is the right 
kind of man, or has the right kind of machinery to put the material 
on the plant in proper form, his knowledge avails him nothing. <A 
spray pump may be capable of applying the spray correctly and 
economically for a period in one orchard, and not be the right kind 
for another orchard. Again, one kind of pump may suit one 
orchard, and good, clean fruit be the result, though perhaps the 
pump is not as good as that of his neighbor, who sees no good in 
spraying because his fruit is spotted or worm eaten. With the 
present day advance in all kinds of machinery, it often pays a man 
to practically give away an old machine for a new one of more 
efficient pattern which may be better suited for the work in hand. 
Spraying, therefore, is a question of individuality and spraying 
machinery
