Publisher's Synopsis
Excerpt from A Comparison of Two Rodent Repellents in Broadcast Seeding Douglas-Fir
While this test is directly concerned with effectiveness of two repellents in protecting broadcast seed from rodent consumption, some basic differences between the two chemicals should be noted. When applied with a solvent that transmits some repellent into the seed, tetramine gives a degree of post-emergence protection to the seedling itself. Endrin, however, does not possess this systemic potential. While both chemicals are highly lethal to rodents, bio assay studies by the U. S. Fish and Wildlife Service suggest that mice develop some aversion to seed treated with tetramine, but much less aversion to Endrin-treated seed. Thus, broadcast seed may be protected primarily through education in one instance (tetra mine); and through population reduction in the other (endrin). Endrin also possesses insecticidal properties that may be of considerable importance. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
