Nicotine dust and arsenical sprays for plant pests
A guide notes that a dust containing 4 percent nicotine and 10 percent lead arsenate yields the best results. If unavailable locally, consult the county extension agent or the College of Agriculture for sources. Arsenate of lead or lime mixed with arsenical mix at one to ten parts lime provides an effective dust. A suitable gun and a funnel attachment improve application efficiency and ensure thorough coverage of plants and insects.
