VEGETABLE DISEASES. 



Artichoke Leaf Spot (Ramularia cirerc^).— This is a 

 fungus said to be the cause of the leaves of globe arti- 

 chokes becoming spotted and dying, and the plants con- 

 sequently prevented from producing flower-heads. 



Remedies. — We know of none, and can only suggest 

 burning infected foliage to prevent the disease spreading. 



Asparagrus Rust (Puccinia asparagi).— This fun- 

 goid disease has committed terrible havoc among the 

 asparagus crop, especially in the Evesham district. It 

 attacks the plants late in the year, and causes the shoots 

 to turn black. The disease seriously weakens the growth 

 of the plant, and ultimately kills it. 



Remedies. — Spray the foliage every ten days during the 

 summer with the Woburn Bordeaux Emulsion (Formula 

 21), or the ordinary Bordeaux Mixture (Formula 20); this 

 acts ais a certain preventive against attack. In the event 

 of plants being infected the proper remedy is to cut off 

 the foliage and burn it. 



Bean-Pod Canker.— The pods of runner and kidney 

 beans are now and then attacked by a disease which ap- 

 peal's in the form of dark-coloured specks encircled by 

 a reddish line. These spots increase in size, form de- 

 pressions in the surface, and eventually become covered 

 with a white fungoid growth. The disease often appears 

 on the stems, and when it encircles the latter the upper 

 part of the shoot dies. Beans so attacked are worthless 

 for food.
