TOLMAN SWEETS — THIRD ORCHARD. 



The results on plot 13 indicate that sprayings made as late as 

 August 1, have little value in controlling the disease. The results as 

 a whole agree with those of the previous year in showing the value 

 of sprayings made in late June or early July. The K. L. S. mixture, 

 the self-boiled lime-sulfur and the Bordeaux gave very satisfactory 

 results. The data on plot 9 shows that fruit spot may be fairly well 

 controlled by a Bordeaux that has but one pound of copper sulfate 

 to the barrel. None of the fungicides produced any injury to foliage 

 or fruit. 



In 1910 the comparative merits of Bordeaux and lime-sulfur were 

 given a further test in the Baldwin orchard of A. R. Marsh of 

 Stratham, N. H. In every case the lime-sulfur used was diluted to 

 a specific gravity of 1.010 (a dilution of 1 gallon to about 30). The 

 arsenite of lime was prepared according to the formula of Stewart* 

 of Pennsylvania. The first spraying was made May 7, before the 

 flower buds had opened, and the second May 28, just after the 

 blossoms had fallen. Only plots 2 and 3 received the first spraying. 

 Light showers followed each application. The data on the condition 

 of the foliage is the result of an actual count made June 23. Notes 

 were taken on about 1000 leaves from each plot. The results on 

 the apples were obtained by an actual count of total dropjjed and 

 picked fruit.
