Description: A 2-percent water soluble solution of 2,4-D was as effective as 50-percent H₂SO₄ for stimulating gum flow from slash pine in stands of natural reproduction. In the 4-year study reported here, there was no appreciable difference in gum yields for zny one year of work, for either front or back faces, and for the entire 4 years of production. The herbicidai treatment is noncorrosive, provides safer working conditions, gives longer life for galvanized iron cups and gutters, and will produce higher grades of gum.
