Treatment. — Cucumbers at Ilicksville, N. Y., were sprayed 

 with Bordeaux mixture as follows: June 13, 20 and 29. As 

 there was a bare possibility of killing an occasional beetle, green 

 arsenite was added to the Bordeaux mixture at the first spraying. 



June 11, marginal squashes at south end of field where beetles 

 had commenced work were dusted with green arsenite. 



June 13, the remaining marginal squashes were treated as fol- 

 lows: One-fourth dusted with green arsenite, one-fourth dusted 

 with lend arsenite, one fourth sprayed with green arsenite in water, 

 one-fourth sprayed with lead arsenite in water. June 24 the first 

 cross rows dusted with green arsenite and lead arsenite; June 29 

 last planting of cross rows dusted with green arsenite and lead 

 arsenite. 



At Floral Park the muskmelons were sprayed with Bordeaux 

 mixture on June 14 and 21 and July 1, green arsenite being used 

 with the mixture at the first spraying.

 senite, one-fourth sprayed with green arsenite and water, one- 

 fourth sprayed with lead arsenite and water; June 21, dusted first 

 cross rows of squashes with green arsenite and lead arsenite. 



At Smithtown Branch the field of cucumber vines was sprayed 

 with Bordeaux mixture on June 29 and July 20 and 28. Very 

 few beetles occurred on this field, hence no other treatments were 

 made.

 sprayed with Bordeaux mixture (l-to-8 formula) were injured 

 not only the first time when green arsenite was added, but also at 

 the second spraying when the latter was not used.
