CABBAGE GROWING. 7 
the half-grown worms to the frequent freezing and thawing and kills off 
the larger part of them. 
THE HARLEQUIN CABBAGE BUG. 
This insect is a true bug., similar to the squash bug, and feeds by 
sucking the juices. Where this insect is prevalent it is a serious menace to 
the industry because of the difficulty of combating it. The remedy is to 
spray with a contact poison, but the insect is difficult to combat, because of 
its habit of hiding among the leaves. So far the pest has not become gen¬ 
eral over the State, but has been found in a few places. 
CABBAGE MAGGOT. 
So far this insect, which is a serious menace to the industry in some 
parts of the East, has not been reported in this State. The maggot is the 
larvae of a small fly. The adult lays the eggs on the young plant, near the 
surface of the ground, and the maggots feed in the stem of the plant under 
ground and destroy the plant. 
FUNGOUS AND BACTERIAL DISEASES 
The cabbage in Colorado seems to be almost immune to fungus dis¬ 
eases. 
Black rot of cabbage occurs intermittently. Some years the crop has 
been seriously affected with this disease and, the year following, the same 
land in cabbage did not show any signs of the disease. 
CLUB FOOT. 
This dreaded eastern cabbage disease is hardly known in the State. 
Turnips have occasionally been found affected by the fungus, so that it is 
probably that, because of some peculiarity of Colorado soils, such as the al¬ 
kalinity, the fungus does not thrive here. 
COST OF GROWING AND AVERAGE PRICE OF CROP. 
The cost of growing crops necessarily depends upon the character of 
the soil, condition of the land, distance from market, etc., so that an exact 
estimate is hard to make. 
The following figures are estimated on the basis of the cost of grow¬ 
ing and marketing potatoes and sugar beets as given by the Greeley Com¬ 
mercial Club: 
Fertilizer (10 tons per acre).$ 5.00 
Plowing . 2.50 
Leveling and harrowing. 1.00 
Seed .50 
Growing plants . 1.80 
Setting plants . 6.00 
Cultivation and ditching. 2.50 
Hoeing . 2.00 
Irrigating . 1.50 
Cutting and hauling. 10.00 
$32.80 
This cost is two dollars and twenty cents less than for potatoes, and 
twelve dollars and twenty cents less than for sugar beets. 
Like all perishable truck crops, the price of cabbages varies inversely 
with the size of the crop. By far the larger part of the crop is shipped out 
of the State, so that local consumption makes no difference with the price. 
Neither does the size of the crop in the State seem to make any material 
.difference in the price, because other competing cabbage-growing districts 
produce the larger part of the total output. 
The following table, taken from the books of one of the potato and 
cabbage buyers at Greeley, shows the price paid the growers each year for 
a consecutive period of ten years: 
Year 1899 .$ .40 per hundred 
Year 1900 .50 per hundred 
Year 1901 .75 per hundred 
Year 1902.25 per hundred 
Year 1903 .40 per hundred 
Year 1904 .25 per hundred 
Year 1905 .50 per hundred 
Year 1906 .25 per hundred 
Year 1907 .50 per hundred 
Year 1908 .75 per hundred
