started to such an extent that the leaf rollers were able to penetrate 

 the buds and thus, in large measure, avoid the poison. There 

 appeared to be at this time more leaf roller injury to both fruit and 

 foliage of the check trees. 



An examination of this orchard July 14th showed a few recently 

 laid eggs and some side injury on the greenings and decidedly more 

 on the adjacent Baldwins. Some larvae were found in the calyx 

 cup. The setting of fruit on the experimental trees is scanty and the 

 crop has been still more reduced by a heavy drop. 



Plot 3 was sprayed for the third time July 28th, the day being 

 cloudy and still and the conditions almost perfect for good work. 

 The trees were well covered with the spray and dripped a little. 

 The work began at 8.45 a.m., was completed about 10 a.m. and rain 

 began falling about 10.30 and continued most of the afternoon. The 

 same formula was employed as before and possibly a little more spray 

 was applied, since the pressure tended to remain at about 210 

 pounds. Side injury was easily found and some eggs were observed 

 in the red stage though no recently deposited ones were seen.
