INDIANA HORTICULTUKAL SOCIETY. 44:3 



Mr. Johnson: Are they wasps or yellow jackets? 



Prof. Troop: These are the same. 



Pi'esident Stevens: We must confine ourselves more closely to the 

 sub.iect under discussion. I anyone has any further remarks to make on 

 this subject we would be glad to hear from them now. 



Mr. Lafuse: I liave had experience raising plums as well as raising 

 apples. It seems to me that it is impossible to destroy the curculio by 

 spraying. I have found that air-slacked lime mixed with wood ashes, 

 applied in the morning before the dampness of the dew is off of the trees 

 is more successful than spraying. 



In spraying for the codling moth I would say that I spray before 

 the leaves are on the trees with the Bordeaux mixture, and as soon as 

 the apples begin to form I spray again. The best stuff I have ever used 

 is Green's arsenoid, which is made in Cincinnati. It will stay on the 

 foliage three times as long as the solution from Paris green, and I think 

 it is more effective. 



This gentlemen spoke about the fruit all being stung by insects. I 

 noticed this year that early in the season the insects were very scarce. 

 I remember that we had a cold, chilly spring, and that the insects were 

 very scarce. Along in the summer when it began to get warmer they 

 began to get very numei'ous. They came along in June and spoiled the 

 apples after they were seemingly set on the trees. How late would you 

 recommend spraying, Mr. Troop V 



Prof. Troop: Until about the 20th of June. 



Mr. Henby: I should like to ask Mr. Williams one question, and that 

 is this: My understanding was that the apple crop in our location, and 

 all over the State, was only about fifteen per cent, of the usual apple 

 crop. I should just like to ask Mr. Williams as to the per cent, of apples 

 he got from his trees compared to the prospect of growth early in the 

 spring. Now, we atti-ibuted our loss of the apple crop to the cold weather, 

 extreme cold weather, during the blooming season. We thought we had 

 a hundred per cent, of blooms. It seemed to us that we had the best 

 prospect for a crop we ever had, and we didn't have over fifteen or 

 twenty per cent, of a crop. So it seems to me that we certainly could 

 not have saved our crop by spraying this season. 



Mr. Williams: I will say that we had a heavy bloom, and we also 

 had apples, but I think the spraying saved nearly every apple that set 

 on the tree. I think I should attribute this to the spraying. 



Mr. Henby: What per cent, did you have compared with the bloom, 

 supposing you had one hundred per cent, of bloom?
