CHAPTER XXI. 



RUST AND INSECTS. 



To avoid scriotis effects from either never have an 

 old bed. TIM. 



RJsT or blighting of the leaf of the plant is one of 

 the greatest obstacles in many sections to suc- 

 cessful strawberry growing. This is not a disease 

 of the plant itself, but the growth of a parasite or 

 fungus upon the leaf, which, if abun- 

 dant, does great injury to the plant, 

 hindering its growth and development, 

 and causing a failure of the crop of fruit. 

 Some varieties are more liable to rust 

 than others, and the trouble 

 appears to be greater in some 

 neighborhoods than others. The 

 reader will find below some inter- 

 esting expressions on this subject, 



SAMUEL MILLER The Bordeaux mixture, if used as a spray, 

 will prevent leaf rust. Mo. 



Beds that are only fruited one season are not usually troubled 

 G. S. BUTLER* with rust or blight. I use Bordeaux mixture, 

 if I see trouble. Conn. 



Rust may be effectually checked by spraying, but prevention 

 is better than cure, and there are so many varieties not subject 

 EDW. W. CONE to this disease that one can easily choose 

 those not liable to it. On ground treated to barn-yard manure, 

 plants are much more liable to rust than where a commercial 

 fertilizer is used. Wis. 



CHARLES WRIGHT Have tried nothing to cure leaf blight; 

 usually secure such varieties as are not subject to it. Del
