TIME TO SPRAY APPLE TREES.

Within a few days the apple bloom will bej at the proper stage to spray for the apple worm and thus increase the apple crop this year many fold. Poison must not be sprayed on the trees while the bees are working on the blooms, but as soon as about three-fourths of the petals have fallen from the little apple the bees will no longer be attracted to the apple blossom. That is the time to cover the foliage and small apples’ with a spray containing a .poison, preferably arsenate of lead. Then when the worn hatches his first meal means death. Here is a formula used by C. L. Burkholder, Purdue University extension horticulturist: One pound powdered or two pounds paste arsenate of lead and one and one and a ■ half gallons of liquid lime sulphur should be added to each fifty gallons of water. Cover all the tree thorpughly with this spray.
