8o AGRICULTURE OF MAINE. 



Mr. Mitchell: They got soaked with dust, it is very 

 much easier to soak an aphis with dust than Uquid because the 

 hquid runs off from him. Have they used much oil in Maine r 



Mr. Yeaton : Haven't used much of any. The oyster-shell 

 bark louse became more numerous last year than ever before. 

 Orchards thoroughly sprayed with lime-sulphur are now over- 

 run with bark lice. 



Mr. Mitchell: We haven't had any particular trouble 

 from it. We occasionally find a few. Most of my orchards 

 haven't had a drop of spray for two years, just the dust, i 

 imagine lime-sulphur in a dormant period is the only thing 

 that would check them. 



Mr. Brown : Do you use a dormant spray, as I understand ? 

 You can use the dust for a dormant? 



Mr. Mitchell: No, you can't use the dust for dormant 

 spray. I have omitted the dormant spray for two years, except 

 the experimental plots. We haven't had San Jose for two 

 years. 



Question : You will have to use dormant for that, won*i 

 you? 



Mr. Mitchell: I think so, to clear up the scale again and 

 make sure against the first moth — a good cleaning up for a 

 sanitary measure, and if that doesn't reappear, then I can go 

 a couple of years with just the dust, but for a dormant spray, 

 you have still to stick to whatever you have been using. 



Mr, Eraser: If any one has a garden and has rose bushes 

 with aphis on them, and they want a cheap duster, take a piece 

 of cheese cloth and put the mixture in it — it is the cheapest 

 duster made, no patent on it. We use it all along the nursery 

 rows where our small buds are affected with aphis. 



Mr. Yeaton : What do you use inside the cheese cloth ? 



Mr. Fraser: Tobacco dust, the cheapest thing of all. 



Mr. True : Is there any control for the trypeta ? 



Mr. Mitchell: That is what we call the railroad worm. 

 The only thing you can use for that is arsenate of lead, and 

 the a]>j)lications of arsenate of lead as they have been made 

 have not proven very successful. Of course, general sani- 

 tary measures are good and arsenate of lead helps some to 

 this end. A good many orchardists have plenty of railroad 

 worms in spite of that.
