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.
