STUDIES IN BACTERIOSIS. IV.—“STRIPE” DISEASE OF TOMATO

Abstract

SUMMARY. 1 A Stripe disease of tomatoes growing under glass is described. 2 The causal organism is a small yellow bacillus believed to be identical with Bacillus lathyri. Manns and Taubenhaus. 3 The effect of manurial treatment on the incidence of the, disease shows that excess of nitrogen increases susceptibility in the plant and this can be largely counteracted by increase of potash. 4 Different varieties of tomatoes show varying degrees of susceplibility to the disease. 5 It is tentatively suggested that the Grand Rapids Tomato Disease, described by Smith, may be identical with this Stripe disease and that the organism which has been described as the cause of the Grand Rapids Disease may prove to be a saprophyte.
