EXPERBIEXT STATIOX EEPOET. 593 



''The result of the work is that some who have failed with it will 

 spray Avith lime, salt and sulphur the coming season; others who 

 had fair success with it will give it another trial, while those who 

 were successful will continue to use it. In all cases I have urged 

 very thorough work and a stronger mixture, and from all I could 

 learn I believe the tendencv to be in this direction the coming sea- 

 son." 



In a number of cases two applications, fall of 1905 and spring 

 of 1906, were made, and usually with excellent results. In others 

 "Scalecide" was applied in fall, and lime, salt and sulphur in 

 spring, and in one large orchard, so badly infested in 1905 that the 

 fruit was largely unsalable, the insect was almost completely eradi- 

 cated. The owner referred to this in a letter dated in Xovember;, 

 when he mentioned the scale as a ''rare bird" on his place. 



On the Experiment Orchard **Scalecide'' was used in the fall of 



1905, and the trees remained in excellent condition throughout 



1906, as appears hi another part of the report. 



An orchard of large apple trees, veiy badly infested, located not 

 far from Xew Brunswick, was sprayed with a 1 to 20 mixture 

 through the Niagara sprayer belonging to the Station, under Mr. 

 Dickerson's supervision, in the fall of 1905, and again early in. 

 April, 1906. Examination made Xovember 1st In' Mr. Dickersoa 

 and myself shoAved some trees almost entirely clean and others, 

 badly infested the year before, in very fair condition, all the fiiiit 

 seen being fairly or altogether clean. It was also noticed here that 

 the last year's scale covering still remained plastered on many 

 trees, giving the appearance of a worse infestation than actually 

 existed. 



The Dickerson peach orchard near Chester, Morris county, con- 

 taining between five and six hundred bearing trees, variably in- 

 fested, were sprayed Xovember 9th to 11th, 1905, with the 1 to 

 20 mixture, and the trees remained in good condition throughout 

 the season, though by no means free from scale at the end of the 

 season. 



Experiments wei'e also made with the mixture as a sunmier ap- 

 plication on apple, peach and plum, with the result that it can be 

 used after midsummer with good effect and a fair degree of 

 safety, but on the whole such applications are not advised except 

 on trees so badly infested that the life of the tree is threatened.
