ARSENATE OF LEAD KILLS CHERRY SLUG

When Cherries Are Half Grown Use Either White Hellebore or “Black Leaf 40.” (By C. P. GILLETTE, Agricultural College, Fort Collins, Colo.) Whether or not the cherry trees bear a crop, they should be protected against the loss of foliage from the attacks of the pear and cherry tree slug. When the cherries are very small, the trees may be sprayed with arsenate of lead in the proportion of one pound of the paste to each 30 gallons of water. Instead of using the arsenate of lead, after the cherries are half grown or more, use either white hellebore in Jhe proportion of one ounce to three gallons of water, or “Black Leaf 40" in the proportion of one part to 800 parts of water, and make a thorough spraying for the purpose of covering the upper surfaces of the leaves. The “Black Leaf 40” will only, kill the slugs with which it comes in contact, while the hellebore will kill all slugs that eat it for several days after the application is made. The advantage of using the hellebore or “Black Leaf 40" after the fruit is well grown is that they do not endanger the people who eat the cherries after they are ripe. If one has only a few small cherry trees, the slugs may be quite easily removed by thoroughly dusting the foliage in the heat of the day with air-slaked lime or fine road dust
