Remission of Symptoms of Clover Club Leaf Following Treatment with Penicillin. I. M. Windsor, Research Assistant, Department of Botany, University of Illinois, Urbana 61801; L. M. Black, Professor, Department of Botany, University of Illinois, Urbana 61801. Phytopathology 63:44-46. Accepted for publication 14 July 1972. DOI: 10.1094/Phyto-63-44.

Crimson clover plants affected with clover club leaf disease showed remission of symptoms after treatment with either tetracycline hydrochloride or penicillin. These compounds were administered as solutions of 100-1,000 µg/ml in distilled water, in which the potted plants were soaked for 24 hr at 7-day intervals over a period of 1 month. No permanent cures were effected. The implications of this finding on the suspected mycoplasmal etiology of the disease are discussed.
