Aleurodes eugeniae Tar. aurantii is a small scale insect which attaches 

 itself to leaves. It has the appearance of small black scale with a white 

 border. Remedy : rosin wash as described above. These two pests are very 

 minor ones in the Bombay Presidency. 



So far we have been tronbled with no serious fungus diseases of Citrus 

 in the Bombay Presidency. There are however two diseases to which 

 attention is drawn here. Scab is common on many kinds of Citrus fruits 

 especially santra, mosambi and k Tgdi limbu. Young branches of kagdi limbu 

 are also spotted with scab. The origin and exact nature of scab is not 

 properly understood. Some fungi are usually associated with scab, but they 

 are by no means proved to be the primary cause of the disease. Some kinds 

 pf bacteria are also found with scab. 



Another obscure disease is a browning of the mosambi fruit called 

 tanibera. The cause of this disease is not known, but it appears that it is 

 generally found in gardens which are perpetually moist as in sugarcane 

 tracts. 



At Wawoshi in the Kolaba District, orange trees were affected with a 

 disease in which the branches died one after another. The cause of the disease 

 is not definitely understood, but cultures from the affected branches showed 

 several fungi of which Nectria, Diplodia and Fusarium were prominent. It is 

 not clear if any of these fungi is the real cause of the disease, for inoculation 

 experiments of these fungi did not produce the disease. Fortunately this 

 disease is confined to only one garden in the Bombay Presidency ; it appears 

 in the rainy season and it is kept well under control by pruning and burning 

 the affected branches and by thoroughly spraying the trees with Bordeaux 

 mixture. 



Fusarium Umonis sometimes attacks plants at the collar. The usual 

 remedy recommended is to cut out diseased parts and paint with 50 per 

 cent, carbolic acid*
