liills some things. I don't think it is as good a fungicide as 

 lime-sulfur. 



Dr. Gilson. Mr. Frost said that it was pretty difficult 

 to get men to do the work thoroughly. I would like to 

 know whether he knows anything that can be put with the 

 commercial lime-sulfur so that you can see it. If there was 

 anything mixed with it so that it would be visible you could 

 look after your help a great deal better and see that the 

 work was being done properly. Some say to use starch, but 

 I don't know. 



Mr. Henry. You can use lime ; you can mix lime with 

 water. 



Dr. Gilson. I have done that once or twice on some 

 commercial, and I didn't see any difference. 



Mr. Henry. That is one of the serious disadvantages 

 of the commercial lime-sulfur, that you cannot see it well 

 enough on the tree and I don't know but that personally I 

 shall have to discontinue the use of it on account of that, 

 because sometimes the wind will change and blow it away, 

 and there are all sorts of different conditions, and when you 

 can't see you don't know whether the whole of the trees 

 have been hit. It is a serious thing. You have got to see 

 whether it is thoroughly sprayed, and where you have hired 

 help doing practically all the spraying you have got to have 

 something that shows. 



Dr. Gilson. I have been informed by druggists that I 

 could add starch, but I never did and I never heard of it be- 

 ing done and I would like to find out if any one knows 

 about how to use it. 



Pres. Has anyone had experience with mixing starch. 



Mr. Smith. I would like to confirm what Mr. Frost 

 says. Oil will spread and crawl, and in an apple tree T 

 think that one application of oil will do as good work as 

 three of lime-sulfur. With lime-sulfur it is dicfficult to cover 

 the trees thoroughly, and in order to kill the scale every in- 

 dividual scale must be covered with the material and on win- 

 dy days it is praptically impossible. You can't get the men 

 to spray against the wind. But the oil will crawl, where the 

 lime-sulfur won't, and take a twig on a small tree, as large 

 as a lead pencil, if you spray it with a strong solution of 

 oil it will crawl around on the other side. You don't have 

 to go around the tree and spray against the wind, but it
