Black Spruce Transplants Unharmed by Overdosage with Mineral Spirits

Foliage discoloration of 2-2 black spruce, Picea mariana (Mill.) B.S.P., transplants was observed in the fall of 1959 where mineral spirits ha- been used as a herbicide three times during the 1959 growing season. The application rate was 60 to 70 gallons per acre; this amount exceeds the maximum suggested by Stoeckeler and Jones (1957) for black spruce at least 1 year old. These authors, and also Woodford and Ivens (1950), imply that the susceptibility of conifers to injury may vary with species, age of plants, weather, soil moisture, shade, or rate of application. This prompted an experiment to learn how foliage or growth of 2-2 black spruce would react to overdosage of herbicide.
