What Are 
Registered Plants? 
Registered raspberry plants 
are extraordinarily free from 
disease; they are strong and 
vigorous and true to name; 
they are grown only by the 
Ohio Small Fruit Improve¬ 
ment Association. Registered 
plants are produced under 
regulations dictated by plant 
pathologists of the Ohio Agri¬ 
cultural Experiment Station 
and of Ohio State University. 
These regulations permit not 
more than one per cent of 
virus disease and not more 
than one-fourth per cent of 
galled plants in the parent 
planting. Contrast these percentages with those allowed by the certification 
regulations of Ohio, Michigan and New York (approximately 9 per cent of 
virus disease and varying amounts of gall). In addition the Association in¬ 
spector must be approved by both the Plant Pathology Department of the 
Ohio Agricultural Experiment Station and the Ohio Department of Agri¬ 
culture. They insist that this inspector must be a plant pathologist trained 
in the detection of raspberry diseases. Three or more annual inspections are 
made and any diseased plants found must be burned out by the inspector. 
You can readily see that registered plants produced under the above con¬ 
ditions must be more disease-free than the average certified plants sold under 
the regular certification regulations. 
Berries such as these are produced by 
Registered Plants. 
What Registered Plants Will Do 
Given proper isolation from out¬ 
side disease sources and proper cul¬ 
tural care, Registered Plants will 
produce for you a healthy, high 
yielding raspberry plantation which 
will remain profitable for a long 
period of years. Losses from the 
virus diseases and from gall will be 
negligible. You will be able to main¬ 
tain a good stand of plants which 
will produce very high quality 
fruit. 
The following summary of re¬ 
sults taken from Michigan Quar¬ 
terly Bulletin No. 11 shows the ef¬ 
fect of disease on yields. 
Plot A—572 disease-free plants set in 
1925. 
Plot B—572 plants purchased from 
trade set 1925. 
YIELD RECORDS 
PLOT A 
26 cases 1st year 1926 
36 cases 2nd year 1927 
50.5 cases 3rd year 1928 
PLOTB 
5 cases 1st year 1926. 
Plants removed to prevent spread 
of disease to Plot A. 
Yield records taken in many 
plantings from registered and un¬ 
registered stock have proved the 
superiority of registered plants.
