ALFALFA; LUCERNE. 



(Mcdicdgo fiutird liiiinaju.s. l'':uiuly Lctiuiiiinusse.) 



Alfalfa is a s1aj)l(' foray;o i)laiit in many jtarts of the world, being grown cxIoiiMively 

 in EuroiJO, Asia, and South America, as well as in this country. Excej)t in Hhij)nient8 

 of iiay, the only danger of introducing pe.sts is with the seed. Some very imjiortant 

 European pests of alfalfa have in .some manner already readied this country and are 

 <loing serious damage. 



Most insects attacking cIo\(;r are ])otential alfalfa pests and it is therefore advisable 

 to consult the list of clover pests when dealing with alfalfa.
