132 CALIFORNIA VEGETABLES 



The Asparagus Rust. The disease made a vigorous attack 

 upon California asparagus fields in 1905. A careful study of the 

 disease and experimentation conducted by Prof. R. E. Smith dem- 

 onstrated that the trouble can be controlled by proper use of sul- 

 phur for the protection of the top growth after the cutting season. 

 Since that time, rust has not been considered a menace. Full infor- 

 mation can be had from the University Experiment Station at 

 Berkeley. 



VARIETIES CHIEFLY GROWN IN CALIFORNIA. 



Conover's Colossal : an old standard variety ; large tender stalks 

 of good flavor. Largely grown for the canneries, which use it 

 almost to the exclusion of other sorts. 



Palmetto: widely grown in California; claimed to be earlier 

 than Conover's, also more productive and uniform in size; quality 

 fine; especially favored for fresh shipments from southern Cali- 

 fornia. 



Argenteuil: also called "Giant Argenteuil" and "Early Purple 

 Argenteuil;" approved for shipping in Imperial valley, for size and 

 colors of shoots and tenderness.
