Pear and Cherry Sawfly.

this country there is an objection against using it on account 

 of its poisonous qualities. It is used extensively in the United 

 States for attacks of the sawfly larva and many other insects. 

 It should be applied in the proportion of i lb. of Paris Green 

 to 1 80 gallons of water, carefully mixed and distributed all 

 over the leaves as evenly as possible. Paris Green can be 

 obtained in the form of paste, when it can be much more easily 

 mixed with water than the powder, which is so fine that the 

 least breath of air blows it over the face and clothes of 

 those who are using it. 



These remedies would be applicable to pear, apple, plum, 

 and damson trees. It would be more difficult to apply them 

 to large cherry trees, as their foliage is so thick, and the 

 fruit is often nearly ripe when the attack of the insect is 

 first noted. After the cherries are picked the trees should 

 be dressed to prevent the larvae from devouring the foliage 

 and weakening the trees for the next season.
