30, July 21 and August 15. The rough bark and masses of 

 old scaly coverings formed such a protection that the remedy 

 was only moderately efficient. 



Ten per cent. K-L was not injurious to peach foliage. 



15 PER CENT, K-L-B {Kerosene-Lime-Bordeaux Mixture). 



The K-L-B makes one of the finest and smoothest mix- 

 tures imaginable. It will remain in suspension longer than 

 the very best Bordeaux mixture. On August 23 it was 

 sprayed on a young pear tree with a few scattering scales. 

 There was no perceptible leaf injury and it was very effect- 

 ive. On October 7 not any young scales and only three old 

 ones could be found. 



A four year old apple tree badly crusted with scales was 

 sprayed August 23. This tree had been infested at least two 

 years. Seven w-eeks after spraying there was a very slight 

 sprinkling of both old and young. Considering the serious 

 infestation this treatment was most effective. 



Peach foliage was treated with 15 per cent. K-L-B with 

 very slight injury following, 



125^ PER CENT, K-L-B-P {Kerosene-Lime-Bordeaux-Paris 



Green). 

 A large pear tree badly infested was treated August 19 

 with 12^ per cent. K-L-B-P. Of course a terriffic rain storm 

 followed in a few hours, but the result of this treatment was 

 most satisfactory. 



Spraying During the Dormant Season. 

 The first spraying done with K-L was with a 25 per cent. 

 mixture applied to part of a native plum tree on the Experi- 

 ment Station grounds, March 30, 1904. About six weeks 

 later the Station Entomologist made a careful examination 

 and could not find a living scale on the sprayed portion. 



Comparison with the Lime-Sulphur-Salt Wash. 



In a badly infested peach orchard near Newark the Station 

 Entomologist conducted some experiments last spring with 

 the boiled lime-sulphur-salt wash. To compare remedies side 

 by side the speaker selected eight trees and sprayed them on
