Storage of White Spruce, Jack Pine, and Red Pine Seed Treated with Arasan, Endrin, and Aluminum Flakes

Seed used in broadcast sowing is normally treated with chemical repellents to reduce losses by depredators; the most commonly used chemicals are Arasan and Endrin. Various studies have shown that these chemicals are somewhat toxic to tree seed (1-2, 6-7, 12-13). However, other studies have indicated that the benefits of protection often more than offset the detrimental effects to the seed (3, 9), (5, 8). Freshly pelleted seed has been used inmost studies, and little information is available on the effects of the chemicals on seed that has been stored after treatment. However, in one study treated shortleaf pine (Pinus echinata Mill.) seed was stored for 17 weeks at 380 F. with no adverse effects on germination (10), and in another study treated loblolly pine (Pinus taeda L,) was stored for 38 to 40 days without loss in viability (11).
