Abstract

Choice of an insecticide treatment to be used on a legume seed crop in bloom should be determined by its hazard o bees as well as its economic effectiveness in controlling harmful insects. This is true not only because bees provide the cross-pollination essential to high yield of quality seed but also because most beekeepers still depend on a honey crop for their living.

In 1947 the staff of the U.S. Legume Seed Research Laboratory at Logan, Utah, initiated a study to ascertain which of the principal new organic insecticides could be applied to seed alfalfa in bloom without creating a serious threat to honey bees. This work has been continued each season with the exception of 1951. Most of the studies made prior to 1950 have been published (Todd et al. 1949, Knowlton et al. 1950). This paper is a report of 16 field tests conducted in 1950, 1952, and 1953.
