Introduction

For the past several years observations have been made on the development and spread of the bunch (brooming)[13] disease on Juglans nigra and on other species of walnut growing in the orchards at Plant Industry Station at Beltsville, Maryland. Because of the widespread interest in growing walnuts a brief survey of these observations will be given in this paper together with a summary of the history of the disease and a discussion of its possible effect on walnut production.
