altogether, and to wash the house out well with a solution of sulphate of iron. The black 

 spot (Macrosporium tomato) should be met by thorough spraying with sulphide of potassium 

 and the removal of the diseased parts. 



FUNGICIDES. 



THE following are among the best - known and most efficacious remedies: Ammoniacal 

 solution of carbonate of copper. — Carbonate of copper ioz., carbonate of ammonia 50Z., mix 

 these together in a quart of hot w ater and then add 16 gallons of water ; or ioz. of carbonate cf 

 copper made into a paste with 

 I pint ot water, then slowly 

 add i pint of strong ammonia 

 water (26deg.), then add 

 9 gallons of water. This is 

 almost as good a fungicide as 

 Bordeaux mixture, and does 

 not leave any sediment on 

 the plants. 



Bordeaux Mixture. — ■ 

 Dissolve iooz. of sulphate 

 of copper in a little boiling 

 water and add 5 gallons of 

 water ; slake 6oz. of lime in 

 some water, when it is cool 

 pour it into the solution of 

 copper, and stir all well 

 together. To test the mixture, 

 so as to be quite sure it will 

 not injure the foliage, hold 

 the blade of a bright knife 

 in it for a minute ; if the 

 blade is unchanged it is all 

 right, but if the steel shows 

 signs of a deposit of copper 

 more lime must be added. 



Sulphide of Potassium. 

 — Dissolve ioz. of sulphide 

 of potassium (liver of sul- 

 phur) in a quart of hot 

 water, and dilute it with 2h 

 gallons of water. 



Sulphur in powder (flowers of sulphur) is useful in attacks of mildew to dust plants 

 with, and in greenhouses and vineries, mixed with a little water, to paint the hot-water 

 pipes with as a remedy for mildew, but it should not be used on flues. Flowers of sulphur 

 is a very common remedy, but known more amongst professional growers than to the amateur, 

 which is a pity, as it is very simple and efficacious when applied in good time. That is the 

 point — not to wait until the disease has made serious inroads, as then it is of course more 

 difficult to overcome. Roses are frequently attacked, some varieties being more subject to it 

 than others, but flowers of sulphur is a very good remedy. Amateurs should use more 

 frequently the simple remedies so easily at command, and immediately the presence of the 

 disease is detected. Once a plant becomes much diseased, it rarely indeed recovers health 

 and vigour,
