The Fungus Pests of Garden Plants 



the expense of the nurse-plant. Other cruciferous plants are less 

 seriously damaged by the pest than are Turnips and Cabbages ; but 

 it is evident that if diseased Charlock is near Turnips, the latter are 

 very likely to fall a prey to the disease. We advise the planting of 

 the best seeds, the eradication of cruciferous weeds, and the destruction 

 by fire, wherever possible, of all decaying Finger-and-toe material, for 

 it is in this material that the spores of the disease rest ready for con- 

 tinuing the disease in the following season. It is also desirable that 

 cruciferous plants should not be continuously grown in the same 

 quarter in other words, it would be prudent after an attack of 

 Anbury not to repeat a cruciferous crop on the same ground, but 

 to follow on with a crop of some other class. 



Numerous experiments have shown that slaked lime can be 

 relied on to destroy the spores of Finger-and-toe in infested land. 

 An application of about three tons to the acre as soon as the 

 crop has been removed is usually sufficient. As regards the occur- 

 rence of Anbury in seed-beds, frequent transplantation is a very 

 effectual mode of stopping its progress, for the little galls can be 

 pinched off by the workman, and burned as he proceeds ; and the 

 plant, being invigorated by change of soil, will soon grow away from 

 the affection. In transplanting Cabbages it is a good plan to dis- 

 card and burn such plants as are obviously affected with Anbury. It 

 is worthy of special remark that in market-gardens this disease is by 

 no means so prevalent as to interfere with the routine of cultivation, 

 although the Cabbages, Broccoli, and Cauliflowers grown in these 

 grounds are, under other circumstances, especially liable to attack. 

 By ' other circumstances ' we mean that market-gardens are generally 

 kept under high cultivation, the land being perpetually turned 

 and heavily manured; and these measures appear to keep Anbury 

 away, while they result in heavy crops. But on land less energeti- 

 cally tilled Anbury may prevail to such an extent as to seriously 

 interfere with the order of cropping. Another very important mode 

 of keeping down the pest consists in burning instead of burying the 

 stumps and all other refuse of the crop that cannot be turned to 

 account. Where burning is inconvenient, the burying should be 

 deep to be effectual. 



Confusion may be prevented if we point out that Club-root, 

 Anbury, or Finger-and-toe whichever name may be used is quite 

 distinct from an apparently similar malformation of the root which is 

 sometimes induced by certain characteristics of soil, seed, or manure, 

 and is in effect a case of reversion to the original wild type. Instead
