MR. FOSTER : I would like to ask if the mixture was 

 bought ready made, or the materials bought and mixed at 

 home ? 



MR. HACKETT: Last year we bought our material 

 mixed, a combination consisting of 80 % sulphur, 10 % ar- 

 senate of lead and 10 % filler, lime, I think. At present I 

 believe it is better to buy the mixture already made, because 

 at this early stage there is not enough knowledge amongst 

 manufacturers on this subject to justify the grower in buy- 

 ing the powdered sulphur competitively, the lead in another 

 direction, and the lime in another, and then attempting to 

 get a smooth, even mixture by home methods. Ultimately, 

 if the use of dusting materials increases, as now seems likely, 

 there will undoubtedly be some live manufacturers that will 

 undertake to supply the prime materials for dusting, and 

 thus enable the grower, by mixing these materials at home, 

 to use his judgment as to the combination of fungicide and 

 insecticide his own orchards may need. 



THE CHAIRMAN: Mr. Miles, I miderstand consider- 

 able dusting has been done in Connecticut. I wonder if you 

 can tell us some of the expeiences of the growers in Con- 

 necticut. 



MR. MJLES: I was just thinking about that. So far 

 the results are not very satisfactory. 



MR. HACKETT : So far as I know, there has been no 

 test on a commercial scale in using dust for the dormant ap- 

 plication. Some manufacturers talk of it, but it doesn't ap- 

 peal to my judgment to attempt to apply dust for the dor- 

 mant work. 



THE CHAIRMAN : I take it most of us will continue 

 using liquid spray for several years to come. This year's 

 program is somewhat up in the air — we do not know just 

 what we have ahead of us. We have a shortage of labor, 

 there may be a possible shortage of sugar, and we do not 

 know what the crop in the country is likely to be. Amongst 

 other things, we may possibly have a shortage of spray ma- 

 terials and high prices. Therefore, the question of what we
