What Are 
Registered Plants? 
Registered raspberry plants 
are extraordinarily free from 
disease; they are strong and 
vigorous; they are grown 
only by the Ohio Small Fruit 
Improvement Association. 
The name “Registered” has 
been given to our specially de- 
veloped and specially inspect- 
ed plants to distinguish them 
from the ordinary “state in- 
spected” or “certified” stock 
grown by other nurseries. 
Registered plants are, of 
course, “state inspected”’, but 
in addition they are inspected 
and rogued three times an- 
nually by a raspberry disease specialist from the Ohio Experiment Station. 
Our standards committee (composed of Experiment Station and Extension 
disease specialists) allow a total of not over 1 per cent virus diseased plants 
and not over % per cent galled plants in any registered planting passed 
for plant sale. Ohio nursery regulations and those of other states allow 
3 per cent virus and 1 per cent gall. In addition, “certified” plantings are 
only twice inspected and diseased plants are not burned and not removed by 
the inspector. If diseased plants are found in registered plantings they are 
promptly burned as they stand and then removed from the field. Since 
virus diseases are easily spread by certain raspberry insects, this “burning” 
is a very important factor in preventing spread of disease. During 1941 only 
one-fifth of 1 per cent of our plants were found to be diseased. 
Remember, disease is the most common cause of short-lived, poor 
yielding, unprofitable raspberry plantations. Remember, also, that the 
amount of disease you will have in your planting will depend on the 
amount you start with in your planting stock. Eliminate your disease risk 
by planting Registered Plants. 
What Registered Plants Will Do 
Given proper isolation from outside disease sources and given proper 
cultural care, Registered Plants will produce for you a healthy, high 
yielding raspberry plantation which will remain profitable for 8 to 10 
years. You will not need to start a new patch every 2 to 4 years. Yield 
records have proved the disastrous effect of disease and the vast superiority 
of Registered stock. 
Raspberries are now a very profitable crop if you start right with 
Registered Plants. 
Berries such as these are produced by 
Registered Plants.
