SUCCESS IN MARKET GARDENING 



against the fungous and all other disorders, and 

 on general grounds as well, to put all the vigour 

 we can into the growing plants. We should also 

 bear in mind the great importance of prompt 

 and efficient action wherever disease is apparent; 

 as it will surely and rapidly extend itself, unless 

 controlled. 



Owing, perhaps, to the fact that the varieties 

 and habits of insects have been more obvious ob- 

 jects of study, there has been collected, thus far, 

 comparatively little scientific knowledge concern- 

 ing fungous diseases of plants, and their appro- 

 priate remedies; but vegetable-growers have, from 

 practical experience, acquired much valuable infor- 

 mation (though leaving much yet to be learned) 

 and have been led to devise and apply remedies, 

 some of which are very successful. 



Fungi that live upon dead and decaying sub- 

 stances, such as toadstools, black and blue moulds, 

 and the like, are of little interest to the cultivator; 

 but there is another class, of entirely different habit, 

 that attacks living plants, pushing its own rootlets 

 into the growing leaf or stem or root, and taking its 

 sustenance from the juices so obtained. Plants 

 grown in forcing-houses are especially subject to
