WEEDS AND GRASSES. 265 
It is little less than a crime to cut seed from a 
dodder-infested field and put it on the market. 
While it is true that most of the dodder seed can 
be taken out, yet unfortunately most seedsmen are 
too careless to do this and thus the pest is wide- 
spread and immense damage results. 
There is a clover dodder that operates just as 
does the alfalfa dodder, another one seen on mint, 
and one on flax. I do not think these dodders able 
to grow on other plants than the one species they 
select. 
To avoid dodder get samples of alfalfa seed from 
your dealer and submit them to your experiment 
station, or to the Department of Agriculture for 
examination for dodder. If it is present in any- 
thing more than an infinitesimal amount inform 
your dealer and choose seed from another bin. It 
may not help to choose another seedsman, and then 
again it may.
