Semesan 
For flower and vegetable seeds and to control 
brown-patch 
Diseases carried on the seed often reduce 
germination and cause a poor stand, 
lowered quality, and unsatisfactory yields. 
Destroy these disease organisms without 
injuring the seed by treating your seeds, 
bulbs, roots, corms, and tubers with 
Semesan. Easily and quickly applied as a 
dust or liquid. Effective in controlling 
damping-off of seedlings. One ounce 
treats 15 to 30 pounds of seed. Semesan 
also controls brown-patch in lawns and is 
recommended where soil-fertility is high.

Formaldehyde 
For wheat and barley 
smut, use one pint of 
Formaldehyde in 40 gallons

seed in tubs; cover several 
hours; sow damp. For oat 
smut, spray oats with one 
pint Formaldehyde in 10 
pints of water. Sack or sow. 
For Potato Scab and Rhizoctonia 
Soak potatoes 3 or 4 minutes in warm 
solution (124 0 to 126° Fahr.) of 1 pint 
Formaldehyde in 15 gallons water. Small 
lots on the stove in washboiler; larger lots 
in tank heated with tank heater or by 
steam from tractor or other boiler. 
Treat soil with Formaldehyde to over¬ 
come root-rot of most vegetables (U. S. 
Bulletin No. 217). Will prevent onion 
smut, lettuce rosette and rot, tobacco 
bed-rot, and damping-off fungi.

Form-O-Fume Formaldehyde Dust 
Damping-off is a costly plant disease 
well known to growers. It is characterized 
by a rotting of the seedling at the soil-line 
or by decay of the roots. This destruction 
or stunting of young plants is due to fungi 
which live in the soil and attack the roots 
and stems of seedlings in order to obtain 
nourishment. This saps the strength of 
the young plants and they are weakened 
or die. Form-O-Fume treatment is easily 
applied, quick in action, certain in results, 
and very economical. It protects against 
the loss of expensive seed and saves valua¬ 
ble time otherwise spent in replacing 
“damped-off” plants.

Cuprocide Red Copper Oxide 
Recommended to prevent seed-decay 
and damping-off. It assures profitable 
stands even under adverse conditions. 
Cuprocide can be used on both vegetable 
and flower seeds—simply shake a small 
portion together with the seed. This is a 
safe and very cheap treatment.
