Millions of dollars worth of Cuban sugar may be saved as the result of experiments involving successful use of the new weed-killing preparation 2, 4-D against tree-like woody weeds, it was announced by the University yesterday.

The discovery was made by Kenneth V. Thimann, Professor of plant physiology, after months of experimentation at the Atkins Institute in Soledad, Cienfuegos, Cuba. The weed apparently eliminated by the experiment is the Aroma marabu weed, which had overgrown large acreages of sugar land on the island and is also a problem to cattle raisers in the region.

Outlining his work in the current issue of Science, the magazine of the American Association for the Advancement of Science, Thimann said, "the experiments are being continued, as they give promise of the possible reclamation of land which up to now was considered virtually unavailable."
