Spraying acti-dione on the trunk of a pruned sugar pine crop in a sugar pine production area off the Bartle-Mineral Lake Raod. This chemical is sprayed to 1/2 the height of the tree or 7 feet if the tree is less than 14 feet high. This chemical has proved quite effective in control of blister rust on western white pine and this is part of the experiment to determine its effectiveness in control of blister rust on sugar pine.

1967. Dorena Seed Orchard. The original seedling frames used for inoculation seedlings in the inoculation chamber. Note that the seedlings were planted in asphalt pots separated into rows by veneer partitions. In later years, the wooden pallets were replaced with reusable plastic pallets and the seedlings were planted in a grid pattern on a whole-pallet basis. Wood siding continued in use for the upper frames. Photo by: Jerry Barnes Date: 1967 Credit: USDA Forest Service, Region 6, Dorena...

A ‘historic’ 1968 document with Jerry Barnes hypothesizing and discussing that the resistance from some parent trees of western white pine might be controlled by a single major gene. This was not ‘accepted’ by contemporizes elsewhere, who did not see it in their own trials, but was formally recognized in the 1990s by Richard Sniezko and Bro Kinloch and documented further in: Kinloch, B.B. Jr.; Sniezko, R.A.; Barnes, G.D.; Greathouse, T.E. 1999. A major gene for resistance to white pine...
