Table XVI. — Worms killrd in the second brood by curly sprayiiii/s, Lchi 



orchard, 1906. 



These results show an even hig'her killing power in the calyx than 

 in the former tests, due, no doubt, to the fact that the small trees were 

 easier to spray thoroushly and that more liquid was applied in pro- 

 portion to the apples. 



In the Smart c*c Hatch orchard in l',)0() and in the Provo tests the 

 number of worms present to begin Avith Avas much smaller, and those 

 left after the early sprayings Avere so few in numbers that in some 

 cases the individual variation in the trees Avas greater than the diifer- 

 ence between the sprayings. The actual percentages are therefore of 

 little A'alue. This is readily understood if one considers that Avith so 

 few moths in the orchards some trees might not be A'isited at all.

The general aA-erage of Tables XYII and XVIII. Avith one excep- 

 tion. Avill be seen to be the same as that of the others. The actual 

 percentage killed is less than where there were more worms; but as 

 the Smart & Hatch orchards were only 3 per cent AAormy for the 

 season and the Provo orchard but a trifle over 1 per cent wormy, the 

 results are entirely satisfactory'.
