48 First Report on Economic Zoology. 



Tkeatment. 



The bushes should be sprayed with cupram and Bordeaux mixture 

 some time before and after harvesting ; the first application should be 

 about two weeks before the rust spots usually appear. 



Bordeaux mixture may stain the fruit, so that for an early washing 

 before the fruit is picked cupram had best be used, and Bordeaux 

 mixture after harvesting. 



Neither should be used for three weeks before the fruit is gathered 

 as they are to a certain extent poisonous. 



Pkeparation of Cupeam. 



Measure out \ pint of strong ammonia (avoid the fumes), and 

 add it to 2 quarts of water. Weigh out 1 oz. of carbonate of copper, 

 wrap it up in a piece of copper gauze and suspend it by a copper wire 

 in the ammonia liquor. Let it remain all night. Wlien required for 

 use dilute the blue fluid with 12 gallons of water. This is the best 

 fungicide for all ripening fruit. 



Bordeaux Mixture. 



Copper sulphate . . . . 1 lb. 



Lime . . . . . . 1 lb. 



Treacle . . . . . . 1 lb. 



AVater . . . . . .10 gallons. 



Dissolve the copper in 10 gallons of water, boil the lime and 

 treacle with a quart of water for half an hour. When dissolved, mix 

 them together and stir them up well. The mixture is then ready 

 for use. 



Gooseberry Fungus. 



{Puccinia prinjsheimiana, Kleb.) 



The gooseberries and leaves sent are attacked by a fungus. This 

 fungus is the aecidium stage of Picccinia 2Jrin[/sJieimiana of Klebahn. 



The cluster cups or aecidia occur on the gooseberry, both on the 

 leaf and fruit ; the other stages affect certain species of Carex (sedges). 



It is generally seen in damp places, but is rarely in sufficient 

 abundance to do any practical harm. As in the present case it is doing 

 considerable damage, any further notes will be gladly received.
