516. Dhashalaga and Tulshimara are the commonest 

 fungoid diseases of brinjal which the cultivators attribute to 

 not cutting the tap-root at the time of transplanting and also 

 to the roots getting cut at the time of earthing. These are 

 fictitious causes. Root-cutting has something to do, no doubt, 

 with the vigour of plants, and cutting of roots when there is 

 water-logging may indirectly cause spores of fungi to settle 

 in the tissues of the plants, but the exciting cause of the 

 diseases is the presence of the spores in the seed, of 

 a bacillus (Bacillus Solanacearum). Water-logging helps the 

 spread of the bacillus. Every plan taffected with a fungoid 

 disease must be uprooted and burnt. The seed used should 

 be pickled and the same locality always avoided for growing 

 this crop from year to year,
