material evenly and without waste over the surface of the 

 plants. 



If insects are found attacking the plants to be treated 

 for fungous growths, Paris green may be added to the 

 Bordeaux mixture at the rate of from 1 Ib. to 100 or 200 

 gals, of the mixture, and, as stated on a previous page, the 

 lime will prevent this large quantity of the Paris green from 

 burning the foliage and two pests be destroyed at one 

 spraying. 



AMMONIACAL CARBONATE OF COPPER. In conspicuous 

 places the Bordeaux mixture is objectionable on account of 

 the deposits of lime and copper that remain on the foliage, 

 and therefore the above form of copper is used under such 

 conditions. It is equally effectual with the Bordeaux mix- 

 ture while it remains on the plant, but, being quickly solu- 

 ble, is washed off with heavy rains and requires frequent 

 renewals. It is also more expensive than the Bordeaux 

 mixture. 



Formula : 3 oz. copper carbonate, 3 qts. ammonia or 

 sufficient to dissolve the copper, the quantity depending 

 upon its strength. When used, dilute to make 25 gals, of 

 liquid. 



COPPER-SULPHATE SOLUTION. A simple solution of 

 copper sulphate, 4 oz. to 50 gallons, is about equally effect- 

 ual with the last and much less expensive. It must, how- 

 ever, be used after every rain. 



Pumps, etc., for Applying Insecticides and Fungicides. 



For the application of insecticides and fungicides there 

 are a great many pumps, machines, and guns made for the 

 purpose, and any of those made by reliable and long-estab- 

 lished firms may be relied upon to do good work. In every
