Question : Have they controlled it with the sweetened 

 arsenate of lead? 



Mr. Mitchell: Better than they can with the ordinary 

 applications. But if you are bothered seriously with that, take 

 molasses and water with arsenate of lead, about a gallon of 

 molasses to thirty or forty gallons of water and a couple of 

 pounds of lead, and mix that and spray it on the lower limbs, 

 because most of the eggs are liable to get on the lower limbs, 

 and sweetened arsenate of lead is more effective with the ordi- 

 nary spraying. 



Mr. Yeaton : I will say right here that I have been work- 

 ing on that control of the trypeta for the past four years, and 

 that the spraying with the arsenate of lead has had a very 

 wonderful efifect in controlling. Last year, where the orchards 

 were afifected badly, the block that I had under experiment was 

 entirely free. This year I had no trypeta in the whole orchard. 

 In fact, we have had less in Maine this year than for a number 

 of years. It is due to a parasite and a fungous disease that got 

 at the fly — the trypeta this year, that it is lessened so. 



Mr. Mitchell: Was that sweetened arsenate of lead you 

 used? 



Mr. Yeaton : I tried it with both, the sweetened, and the 

 arsenate of lead without the molasses. The molasses seemed 

 to stick it rather better, but I saw no difiference in the control. 



Question : Will the dust spray kill the woolly aphis as well 

 as the green aphis on the apple tree? 



Mr. Fraser : I don't know. 



Mr. Mitchell: Nobody knows that yet so far as I know. 



Mr. Fraser : We hadn't enough woolly aphis to try it this 

 year ourselves. 



Mr. Mitchell: Get a little dust, in a handkerchief, and 

 dust it on some woolly aphis and watch it. Anybody who is 

 interested can take a little hand atomizer and put in it either 

 a spray mixture or a dust, whatever you want to blow, and 

 blow it on and get a little magnifying glass and watch your 

 insect or fungus and see what it does. It doesn't cost you 

 much. And in that way you save hundreds of dollars, some- 

 times. 



Mr. Fraser: Don't buy one of the hand dusters that is 

 made. We have had lots of them to try. There isn't one of 

 them that will last twenty minutes.
