1^^ GARDEN FOES, 



Black Rot of Cabbagre (Pseudomonas caiiipestris). 

 — Tliiy. disease has only recently made ite appearance in 

 England, but has been prevalent in America for some 

 time. Its presence is indicated by the dwarfing or one- 

 sided growth of the plants, and by the heads rotting off. 

 Stems infected have a dark or brown ring in the centre, 

 and the edges of the leavcG turn brown. The disease is 

 caused by a yellow bacterium. 



Eemeuies. — Burn every infected plant promptly, dress 

 the vacant land with gas-lime, and do not grow any of 

 the cabbage family on the same plot for a year or two. 



Cabbag-e White Rust (Cystopus candidus).— A 

 fairly common fungoid disease on cabbages and other 

 plants of the same order. It appears in the form of 

 swollen, white patches, or irregular masses of snow white 

 powder. The effect of an attack is the distortion of the 

 leaf and the ill-health of the plant. It is distinct from 

 the Cabbage or Turnip Mildew (Oidium balsamii) which 

 covers the surface with a white film of mycelium similar 

 to hoar frost. 



PvEMEDY. — There is only one, and that is pulling up au<i 

 burning every infected plant, so as to stamp out the 

 disease. 



Canker and Rot. — The cankery patches and rotten- 

 ness of various roots are caused by wet seasons, sour and 

 very heavy soils. There is no known remedy for these 

 defects. 



Carrot Disease (Plioma sanguinolenta). — A fungoid 

 disease wliich attacks both the stem and the root of the 

 carrot, causing sunken canker-like spots to form on the 

 latter. Wherever the st-ems are to be seen coated with 

 a minute mould, or the roots detected with sunken grey- 

 ish-brown spots, it may be safely assumed that the dis- 

 ease is present.
