rlSnt now furnishes loeal cohoiuorl
for the development of apple scah
This Il Q fungus disease which does I
great deal Of damage to the apples 81
this section, especially In q seasoo
when weather conditions are right
With such weather as we are havin(
at present continued for some weeks
the probabilities are that cur pleas
Ing prospects for an unprecedented
crop Of apples will be blasted through
the ravAges Of this disease.
The trouble Is of fungus nature
and develops upon the blossoms
leaves and fruits. The most damag,
Ia done directly when 1t develops up
on the fruit. In such instances n
and often lopsided and worthless fol
any purposes whatever. The devAl
opment on the leaves often causes the
leaves to fall Of in the later part O.
opment Of the fruit buds which
SnOui0 tive the next years crop.
The trouble has two types Of re-
production. These are known as The
winter and summer spores. Tho win.
ter spores live over on the mimmiet
apples that hang on the trees, on thu
branches of the trees, and on deaf
leaves which lie about under tht
trees. The summer sporeS\ are pro
duced by the growth of the fungus OF
the fruit or leaves and are distribut
cd BY the wind from tree to tree. Thu
conditions for the development Of the
spores on the fruits or leaves arr
plenty OF moisture and warmth. Il
a showery time, when tho foliage II
wet during large part Of the day
We nave these conditions present.
Tho remedy should be preventative
rather than curative. Western grow,
ers have found IT advisable to usa
great pains to plow the dead leave4
under or work them down into tho
soil before any growth starts on thu
tree In tho spring. Where practica',
they have found 1t advisable to rakl
