The seed and seed treatment material should be thor- 
oughly mixed together in a rotary drum mixer until all 
the seed is uniformly coated. In most cases this will 
take from three to five minutes at a speed of forty 
revolutions per minute. If Arasan is used on beans and 
peas, use one-half as much as the Spergon recom- 
mendation. Do not use more material than recom- 
mended. Screen off excess dust. 
Bichloride of Mercury (Corrosive sublimate) treatment 
affecting organism on surface of seeds: 
Cucumbers: Dilute 1:1000, immersing seed for 10 
minutes. 
Less hard seeds: Dilute 1:1000, immersing seeds for 5 
minutes. 
For small quantities of seed dissolve 1 tablet in 1 pint 
of water. 
For larger quantities dissolve 1 oz. of the powder form 
in 71% gallons of water. It is advisable to dissolve the 
powder in a small quantity (a pint or quart) of boiling 
water first. 
Place seeds in loosely woven cloth bags (about half 
full). Submerge bags in solution and stir with a stick 
to loosen adhering bubbles. After soaking the proper 
length of time, remove bags and drain thoroughly. 
Seed should be washed for 15 minutes in several 
changes of water. Then spread in thin layers to dry. 
Do not prepare solution of bichloride of mercury in 
metal containers. Only glass, earthenware or wooden 
vessels should be used. In working with the compound, 
the greatest caution should be exercised, as it is ex- 
tremely poisonous. 
HOT WATER TREATMENT FOR CONTROL OF 
SEED-BORNE DISEASES 
BLACK ROT. Cabbage seed which is not known to be 
free from the black rot organism should be soaked in 
water held at 122° F. for 25 minutes (cauliflower and 
broccoli, 18 minutes). Use an accurate thermometer 
and hold the temperature within 1° F. of that specified 
to control the disease without injuring the seed. Fill a 
cheesecloth bag two-thirds full of seed, tie the top, 
immerse it in the hot water and then stir it enough to 
remove the air. After treatment, dip the seed in cold 
water, drain and spread in a thin layer to dry. 
Use new land for seedbeds or old land in which cabbage 
or other related crops have not been grown for two 
years. 
Do not use plants from a plant bed in which black rot 
has been found.

Sprays or dusts required per acre depend chiefly upon stage of 
growth, variety of crop and severity of insect infestation or disease 
infection. Spray for small plants require from 75 to 100 gals. per 
acre, for larger plants and heavy growth 100 to 150 gals. per acre. 
Dust for small plants 25 to 30 Ibs. per acre, for large plants and 
heavy growth 35 to 50 Ibs. per acre.
