especially from fungoid attacks. Fungicides aro undoubtedly useful, but 

 the cultivator will do well to strain every nerve to obtain plants of 

 great constitutional vigour, and to develop them by appropriate cultural 

 methods. High forcing, especially by an unbalanced plant-food con- 

 taining an excess of available nitrogen, will certainly induce liability 

 to disease, although if the plant be not attacked, a greater amount of 

 ▼eget&tive growth will doubtless be produced ; but this increase is often 

 of doubtful advantage.
