at 1 oz. per 2 gal. Acid 
peat desirable in soil 
mixture.

plants. 
Cuprocide. 
Steam sterilize soil mix- 
ture, or treat soil with 
Formacide.

REMARKS 
In case it is a virus, 
keep insects under 
control to prevent 
spread. 
May be caused by 
high pH, over-water- 
ing, root nematodes, 
symphylids. 
Sometimes called yel- 
lows. Spread by aphids 
and leafhoppers — 
keep them under con- 
trol. 

Treat seeds. Dust in- 
fected areas to pre- 
vent spreading. 
Regular spraying nec- 
essary.
