Effect of Selected Insecticides and Fungicides on Germination of Douglas-Fir and White Spruce Pollen
Germination of two lots each of Douglas-fir and white spruce pollen was determined in vitro on a pesticide-amended medium. In general, all the pesticides (two insecticides and two fungicides) reduced pollen germination of both tree species; an exception was ferbam which sometimes increased Douglas-fir pollen germination slightly. Additional tests are needed to determine if pesticides affect pollen germination in vivo.
