also effective. No matter which material is used, 
start early and cover both upper and lower surfaces 
of the leaf. 
Midge can be controlled by Loro at 1-800 with 
Grasselli Spreader-Sticker at 1-1200 sprayed every 
third night for seven or eight applications. Nicofume 
liquid at 1-400 with Grasselli is effective and is ap- 
plied the same as Loro. In either case do not apply 
the spray before 10 p. m. as the midge do not appear 
until night. 
Foliar nematode is controlled by Nicofume liquid 
at 1-200 with Grasselli. The material must penetrate 
the leaf to kill the eelworm. Avoid water on the 
foliage as they spread through it. 
Mealy bugs should be sprayed with Loro as 
recommended for red spider. They are difficult to 
control. Azobenzine fumigation is very effective. 
Soil pests including nematodes, symphylids, and 
grubs, are controlled by steam sterilization before 
planting. Once in the bench after planting, there is 
no known control for the first two pests. For grubs, 
lead or calcium arsenate broadcast at 5 lbs. per 
1,000 sq. ft. is satisfactory. 
Sodium selenate or P-40 are being recommended 
for the control of red spider, thrips, aphids and foliar 
nematodes. It is very worthy of trial and if used 
according to directions should eliminate all spraying 
and fumigation for the pests named above. 
DISEASES 
The most serious of these is verticillium wilt. This 
disease organism lives within the plant and no spray 
applied to the outside or any material placed on the 
soil will do any good. Short tip cuttings should be 
taken when the plants are growing rapidly or the 
cuttings purchased from reliable sources. All soil, 
pots and tools should be steam sterilized. 
Stem rot is caused by infection in the propaga- 
tion bench, too deep planting, or poor drainage. 
Septoria spot can be controlled by spraying with 
1 lb. of Fermate and Grasselli at 1-1200. Bordeaux 
mixture is satisfactory but stains the foliage. 

Cutting of flowers before they are fully developed 
impairs the keeping quality. When standards have 
expanded and the center is no longer green, they 
are ready. Pompons are ready when a majority of 
flowers are open. Pompons are usually sold in 9-oz. 
bunches. 
STOCK PLANTS 
After flowering, the plants may be lifted and 
placed close together in a bench in a cool (45° F.) 
house. Benches in shady locations, under dripping 
gutters, etc., are not suitable. The temperature may 
be raised when the plants show signs of growth in 
late winter. Control of pests, especially midge, in 
the stock plants is important. 
CLOTH HOUSE 
Growing of mums under cloth is similar to green- 
house culture. Pompons are generally grown but 
standards may be produced providing they are pro- 
tected from rain when the flowers are expanding. 
OUTSIDE 
Growing of mums without benefit of cloth usually 
gives woodier and shorter stems. The quality is not 
quite as good.as cloth house mums. The tarnished 
plant bug stings the terminal growth and the flowers 
are blasted or otherwise imperfect, and no effective 
control is known, except covering with aster cloth. 
Growing of pompons in the field to be later lifted 
and moved into the greenhouse about July 15 is an 
old practice which no longer is used by progressive 
and good mum growers. Time and labor is wasted 
and although the plants are heavy, better quality 
plants can be produced under glass. 
POTTED PLANTS 
The growing of potted chrysanthemums has fallen 
gradually in disfavor because of the leggy, un- 
sightly specimens which masquerade under the title 
of salable plants! The production of stocky growth, 
with the foliage in perfect development down to 
the rim of the pot and many flowers uniformly cover- 
ing the top, requires considerable skill. That in itself 
should be an inducement to try the growing of these 
brilliantly colored gifts. There is a scarcity of pot 
plants in the fall, and the demand remains constant, 
so that crysanthemums may well be utilized for 
this purpose. 
Dwarfness of habit and comparatively small size 
of the flowers are essential requisites. The button 
types, the Caprice varieties, and Anemones, lend 
themselves well to this treatment. The stocky growth 
eliminates the need of staking, while the numerous 
branches thus produced abound with clusters of 
flowers.
