4th Time. In from ten days to two weeks, according to the 

 weather, use the Bordeaux mixture alone. 



Should the weather be dry and the temperature low no fungous 

 growths will probably appear, when the longer interval may elapse, 

 but if it should be warm and moist the apple scab is likely to appear 

 and the copper should be on the foliage and fruit in sufficient quan- 

 tity to [)reveut its spores from germinating. 



5th Time. Under ordinary conditions, during the mouth of July, 

 only one application of the Bordeaux mixture need be made, and 

 this should be at from two to four weeks from the last application. 



6th Time. After the fruit is nearly grown only the ammoniacal 

 corbonate of copper should be used, and unless the weather be very 

 wet one application will be sufficient. 



THE PEAR. 



1st Time. Before the leaves unfold use the copper sulphate solu- 

 tion for the leaf blight, cracking of the fruit, and the pear scab. 



2d Time. Apply the Bordeaux mixture and Paris green, one 

 pound to 100 gallons, before the blossoms open, lor the codling moth. 



3d Time. As soon as the petals have fallen, repeat with mixture 

 as last used. 



4th Time. From two to four weeks after the last spraying, 

 according to the weather, use the Bordeaux mixture alone for leaf 

 blight, cracking of ihe fruit, and pear scab. 



5th Time. Should the weather be very warm and moist, make an 

 application of the Bordeaux mixture from the first to the middle of 

 August. 



If the pear tree Psylla appears, use the kerosene emulsion as soon 

 as the first one is detected, making a second and third application at 

 intervals of five to seven days. The best time to make these appli- 

 cations is probably from May 1st to June 1st. 



This insect causes the blackness on the leaves and branches during 

 the summer and injures the trees very seriously by sucking the juice 

 from the tender shoots, leaves and petioles. It is so minute as to be 

 detected only by the closest examination, and our orchards are often 

 infested and seriously injured before we are aware of its presence.
