If the disease goes on spreading, spraying 

 with fungicides would render the spores of the 

 fungus incapable of germination, and would 

 therefore be effective in keeping the disease in 

 check. The problem remaining to be solved 

 is how frequently it is necessary to spray, and 

 how soon after complete destruction of the 

 spores will a fresh batch be produced on the 

 same leaf. Bordeaux mixture or Bordeaux 

 paste would probably be a good fungicide to 

 use, and for the sake of efficiency and economy 

 a spray pump with a long bamboo lance 

 must be used, though with the tall trees a 

 boy will have to be sent up. Not only should 

 all the palms that show any signs of disease 

 be sprayed frequently, but also any in their 

 immediate neighbourhood, so as to prevent the 

 spores from spreading. 



The Bordeaux mixture, says the -West Indian 

 Bulletin, No. 70, should be applied in the 

 usual way by means of sprayers, the mixture 

 being made up as follows : 



Copper sulphate (bluestone) ... 6 Ib. 



Unslacked lime .. ... ... 4 ,, 



Water ... ... ... ... 50 gallons 



The 6 Ib. of bluestone is dissolved in 

 25 gallons of water in a wooden tub or barrel 

 by tying it in a piece of sacking and hanging 

 it in the water from a stick laid across the 

 top of the barrel. The 4 Ib. of freshly-burnt 

 unslacked lime is slowly slacked and made up 

 to 25 gallons in another tub. Next the lime-
