All fruit farmers know of the Mally Fruit Fly Remedy. It has had vast repercussions on fruit farming in this country as well as in other fruit producing areas of the world. A sweetened bait with water, sugar and arsenate of lead would be applied with a white-wash brush to sprinkle the poison on the foliage of the peach trees. Poison bait spraying is still the most effective known method of fruit fly control. Arsenate of lead can still be used as the active ingredient in the bait. Sodium fluosilicate is also effective and parathion can be used.
