““Mum’s the Word” . . and right he 1s. 
From now and until late fall mums are the 
concern of many growers. We say concern 
advisedly because this crop is subject to so 
many ailments and failure to discern them 
spells either total loss or else poor quality. 
From the very planting we have to watch that 
spot does not attack the foliage. Fortunately 
it is easily controlled by several fungicides, 
but Fungisul seems as good as any, provided 
that regularity of spraying is_ practiced. 
Serious as spot may become if not controlled, 
a much more serious disease is Verticillium 
wilt which is recognized by the wilting and 
dying of entire plants. Despite sterilized soil 
this is hard to control except by using plants 

which are free from it. There is a definite 
effort to provide such plants. When you see 
lower leaves graying and browning on the 
edges and excessive wilting of the whole plant, 
it usually means trouble. 
These two diseases are bad enough with- 
out having to combat various pests and one of 
these is not readily recognized. We are think- 
ing of the foliar nematode—a_ microscopic 
worm which works under the epidermis of the 
leaf, causes triangular brown areas extending 
from the veins, which later cause foliage drop. 
These nematodes spread by water so that 
keeping foliage dry will help as will spraying 
with double strength nicotine (1-200). 
Then of course there is the ever present 
leaf roller, which becomes serious by neglect. 
Dusting with rotenone or pyrethrum dusts or 
spraying with materials containing one or 
both of these ingredients, the use of tartar 
emetic or arsenate of lead are effective reme- 
dies provided the foliage is coated before the 
larvae begin to roll the leaves. Once they 
reach that stage they are hard to get. The 
various electric killers and traps are a snare 
and a delusion since many of the female moths 
lay the eggs before flying. As a consequence 
the apparent slaughter results in the killing 
of the harmless males and a few females. 
Start protection early and keep at it and 
you'll not have so many sleepless nights. 
In addition, of course, the voracious thrips 
are with us, scraping the surface and speckling 
the leaves, which eventually die off. As to 
remedy—tartar emetic, if you can’t get that— 
try Salp, an excellent substitute. One would 
think that this would be enough, but we still 
have others which are serious. The red spider, 
for example, or the mealy bug, or the ever- 
present aphids, or the bud worms, and lastly 
but certainly not the least is the midge. All 
these can be controlled by spraying or dust- 
ing or fumigating and we feel sure you are fa- 
miliar with the means. If not, here goes briefly: 
Red Spider—Syringe or use any good 
rotenone and oil spray, applied regularly.
