DEF

A bacterial disease that attacks forage grasses and cereal grains.

CONT

Bacterial leaf streak(Xanthomonas campestris subsp holcicola) is widely distributed on sorghums-including sudangrass and Johnsongrass. Other plants that may become infected include corn, pearl millet, and foxtail millet. Narrow, water-soaked and translucent(1/8 by 1 to 6 inch long streaks), with red or brown borders and irregular blotches of color interrupting the streaks, form on the leaves. Irregular, oval blotches develop later as lesions enlarge and merge covering much of the leaf blade. The blotches have tan centers and red or brown margins. When infection is severe, leaves may wither and drop early.

CONT

Maladie des stries bactériennes, Xanthomonas holcicola. Dans le champ, les premiers symptômes que l'on peut observer sont des taches ou des stries discontinues, étroites, d'aspect huileux ou translucides, un peu rougeâtres. Ensuite, le centre des taches devient de couleur tannée. Les stries peuvent s'élargir pour former des taches ovales irrégulières avec des bordures rouges et le centre de couleur tannée. Les exsudats bactériens se dessèchent et forment des croûtes à la surface des lésions.
