The Use of Oil Sprays for the Control of Weeds in Coniferous Nurseries in New York

The annual production of the two New York State Nurseries is 40 million seedlings. This requires that one hundred thousand 4 X 12 seedbeds, or about 85 acres, are in nursery trees at any one time. The use of oil sprays is the routine manner of weed control, supplemented with some hand weeding. In the 4 years, 1947-1950 inclusive, large quantities of oil spray have been used -- approximately 15,000 gallons per year. The year 1946 was one of experimentation, and relatively few beds were treated. The results were so favorable that large scale operations were used in 1947 and subsequent years. While some risk was taken in such large scale use, it seemed necessary in light of the unusual population of weed seed in the ground, due to the necessary neglect during the war period.
