SOMETHING NEW IN SEED TREATMENT 
INHERENT IN EVERY SOIL THERE ARE MOLDS WHICH ACT DET¬ 
RIMENTALLY TO SEED WE PLANT. MANY SEEDS THESE MOLDS WILL DESTROY 
THROUGH ROT BEFORE THEY GATHER ENOUGH GROWTH TO THROW OFF ITS EF¬ 
FECTS. EVEN WHEN PARTLY GROWN THE PLANT SOMETIMES SUCCUMBS TO THEM 
AND THE NAME OF “DAMPING OFF” IS GIVEN THIS OUTCOME. 
NOW AFTER CONSIDERABLE EXPERIMENT ON THE PART OF CHEMISTS, COLLEGE 
AUTHORITIES AND INDIVIDUAL PLANT SPECIALISTS THE PAST FEW YEARS, IT HAS 
BEEN DEFINITELY PROVEN THAT BY DUSTING MANY SEEDS WITH RED COPPER 
OXIDE NOT ONLY HAS ROT OR DAMPING OFF BEEN CONSIDERABLY LESSENED BUT 
GROWTH HAS BEEN GREATLY ACCELERATED SOMETIMES BY AS MUCH AS 300%, 
DEPENDING ON THE KIND OF SEED TREATED. 
RED COPPER OXIDE SHOULD BE USED WHERE EXPERIENCE HAS BEEN UNFAVOR¬ 
ABLE TO CROPS FROM POOR GERMINATION AND “DAMPING OFF.” EVEN WHERE 
YOU ARE NOW GETTING SATISFACTORY RESULTS WE BELIEVE THAT ITS USE WILL 
ASTOUND YOU IN GETTING LARGER PLANTS AND EARLIER MATURITY. 
Red Copper Oxide is inexpensive in price and on the following seeds its use is 
especially valuable. Of all products employed for this purpose it has proven the most 
successful. 
Beet —• Cabbage — Carrot — Cauliflower — Celery — Cucumber — Egg¬ 
plant — Endive — Lettuce — Melon —■ Peas —■ Pepper —• Radish —• 
Salsify — Spinach — Squash — Swiss Chard — Tomato. 
On many flower seeds it also has a desirable effect. 
How to Apply 
Red Copper 
Oxide 
For small seed¬ 
ed plants like 
Spinach or To¬ 
mato, use one 
level teaspoonful 
to the pound of 
seed. On larger 
seeds, such as 
Peas or Cucum¬ 
bers, one level teaspoonful will suffice for a five pound quantity. Seed so treated will keep 
for months provided it is kept in a dry cool place. The seed should be placed in a tight 
container together with the Red Copper Oxide and thoroughly shaken for several min¬ 
utes. It is advisable to fill the jar or drum only half full with seed to insure its complete 
coverage with the chemical. Excess dust may be removed by sieving the treated seed 
over a fine screen and used again for additional treatments.
