SECRETARY BROWN : Combined with the self-boiled, 

 or alone? 



MR. WHEELER: Just the poison alone. 



MR. FROST : In some eases where a furrow could not be 

 jdowed, the Gypsy Moth Commission have used a windrow of 

 oiled hay and Tanglefooted the trees on the outside, but you 

 must be very careful about Tanglefoot on the peach, because 

 it may injure the bark. If the caterpillars were too thick 

 and swarmed over, the hay was burned and new hay put 

 clown. 



MR. WHEELER: Put broad band of Tarvia, about 8 

 inches wide, around the place that you want to stop them 

 from coming in. They will come to that and won't go 

 across, but if it is cold weather you have to renew it every 

 day or so. because it hardens up. That is also a good, effec- 

 tive method of keeping the traveling or crawling insects 

 away from a row of trees around your house. 



MR. WARE : Could creosote be combined with the dor- 

 mant spray to control the tent caterpillar and aphis through 

 the eggs, without injuring the bark of the tree? 



PROF. FARLEY: We have never tried that. I wouldn't 

 want to take a chance on it. 



MR. FROST : I have never tried it. but I have seen trees 

 injured with creosote, which is very injurious to the bark 

 when used in large quantities. 



THE PRESIDENT: Mr. Smith's statement that he con- 

 trolled 100% of the tent caterpillar with lim^e-sulfur is ali 

 we need on that subject. We have never had trouble with 

 the tent caterpillar where we sprayed in the winter with the 

 regular strength lime-sulfur. 



MR. STOCKWELL: Is there any way of spraying the 

 gypsy moth nests? 



MR. MUNSON. If you will spray with miscible oil and 

 put the nozzle close up to th^ nest and be sure to soak it, it 

 will kill the eggs. 



MR. WARE: Is there any difference in the expense of 

 using the dry arsenate of lead and the paste?
