Effects of Systemic Insecticides on the Germination of Unstratified Eastern White Pine, Virginia Pine, and Loblolly Pine Seed Vary Greatly

Systemic insecticides as applied to the seed of fiber, food, and forage crops have been investigated extensively during the past 15 years. Systemic insecticides now have a wide commercial use on cotton seed for planting. Small amounts of these materials adhere to the. seed coat, protecting the cotton seedling against thrips, aphids, and mites. Ivey et al. (1954) undertook some of the early work with organic phosphorous systemic and reported on the success of dithiophosphate compounds on cottonseed. Little investigative work has been done on the potential of systemics on forest tree seed. Systemics nursery seedbeds and in direct seeding operas ns might protect against spider mites, sucking insects such as aphids, coccids, and certain bud- and leaf-destroying insects. The present study observed primarily the phytotoxic effects of several systemics on germination of pine seed.
