HOW TO MAKE 

 Poisoned Bordeaux 



Four povmds of fresh lime, four pounds 

 of bluestone, and four ounces of Paris 

 green, thoroughly mixed in forty gallons 

 of water. In all cases where spraying 

 with Paris green is recommended it is 

 advisable to add the bluestone (or 

 Bordeaux mixture) in order to counteract 

 the fungus diseases at the same time as 

 the insects are destroyed. The bluestone 

 (copper sulphate) should be dissolved by 

 suspending it in a wooden vessel contain- 

 ing four or five gallons of water, and the 

 lime slacked in another vessel; if lumpy, 

 the lime should be strained through coarse 

 sacking. Pour the bluestone solution into 

 a barrel and half fill with water; dilute 

 the slacked Ume to half a barrel and mix 

 the two together. The Paris green should 

 be made into a paste with warm water, 

 poured into the barrel and stirred thor- 



msECTicroEs 



oughly. The mixture is then ready for 

 use. The addition of the Ume prevents 

 the poison from scorching the foliage. 



Lead Arsenate 



Arsenate of soda, 10 ounces; arsenate 

 of lead, 24 ounces; water, 150-200 gallons. 

 "The arsenate of soda, and the arsenate 

 of lead (sugar of lead) should be dis- 

 solved separately and then poured into a 

 tank containing the required amount of 

 water. A white precipitate of lead ar- 

 senate is immediately formed, and when 

 thoroughly stirred is ready for spraying. 

 The preparartion may be used several 

 times stronger without the least danger 

 of scorching the most delicate plants. 

 When sprayed upon the foliage it forms a 

 coating which adheres so firmly that it is 

 but little affected by ordinary rains."
