PROCEEDINGS OF THE ANNUAL MEETING 1^9 



Pi'of. ^^'ail(': No. Ilici-c arc ikiI, [n my kiii)>\i(Ml^c. There may be 

 somelliiim comin*'- out. This is Ihr lime of \-ear. \<)\i kiiuw, in which those 

 things appear. 



Q: Do you use the rej;iihir T.nrch'aux mixture? 



I'i'of. Waite: Yes, sir. 



Q: The strength? 



Prof. Waite: I do noi know the exact forniuhi, but I would use the 

 fifty-gallon formula; that is, six ]»ounds of blue-stone to fifty gallons of 

 water — that is what yon meant by slienglh? A ^fember: Yes, sir. 



Prof. Taft: You spoke of spraying peaches with J'ordeanx mixture. I 

 have used the ordinary strength five or six years and have had no harm 

 whatever. 



Prof. AYaite: There is no question aliout its ])reventin'g curl-leaf, and 

 the curious thing is that many ])eople have done just as you have done and 

 had no harm; but on the other hand, we get most terrific reports of whole 

 orchards defoliated by the use of it, so we are very cautious about 

 recommending it. We do not understand the conditions yet under which 

 we can spray with Bordeaux mixture. 



Mr. Morrill: It has been used very freely in this state. 



Prof. Waite: Well, it defoliated the trees in some cases. 



Mv. ^forrill: Are these rejjorts you have from people .who are careful 

 and who put no insecticide in it? Prof. Waite: Yes, sir. 



IMr. Morrill: I know^ where there has been a great deal of damage done 

 as the result of using Paris green with Bordeaux. 



Ih'of, Waite: But even with the best of Bordeaux there has been. Of 

 course, there has been some very successful spraying of the peach, but we 

 have come to the conclusion, after this year's experience, that w^e are not 

 going to recommend it until we know^ more about it. If people wish 

 to spray with it, all right; but they can do it on their own responsibility. 



^Ir. Morrill : I have sprayed my peach orchards six years with Bor- 

 deaux mixture, fifty-gallon formula, and never had the drop of a leaf 

 from that. 



Prof. Waite: Well, Mr. Hale took the leaves off of his whole Connec- 

 ticut orchard. Then he went to work and applied a strong percentage of 

 nitrate of soda, and the trees grew a new set of leaves. 



Mr. Morrill: Saved the crop? 



Prof. Waite: Saved the crop, after a fashion, all ])ut the quality. They 

 gave a very bright-colored, fruit, because the sun shone through the trees 

 more than it should have done. It colored them up, but they w^ere not 

 right. 



Q: If half of the top of a ]uar tree is black willi pear-blight, is it 

 possible to save the life of the tree? 



Prof. Waite : O, yes. Every inch of good wood below the point actually 

 reached by the disease is jierfectly healthy. 



Q: Below where the leavers aie. say. are six indices where the bark 

 has blight too. 



Prof. Waite: Yes; that is, where the disease is in the bark. 



Q: How will you do it? 



Prof. Waite: You get down bt'low the lowest point in which you can 

 find any disease, and then to make ceitain you are obliged to cut a foot 

 or two below that, to be anvv that you have got to sound wood. All 

 the cutting must be done to absolutely sound wood. The point is to
