Description
Urophlyctis alfalfae, the crown-wart agent of alfalfa, is locally damageable in France in damp or irrigated fields. Field tests, from 1980 to 1983, in plots naturally contaminated by Urophlyctis alfalfae show that among 9 alfalfa cultivars, only those known to be tolerant to soil wetness have a good resistance to U. alfalfae ("Paider" and 2 old french cultivars "Marais de Challans", "Marais de Lm;on"). The use of such cultivars in damp soils would allow to reduce the damages of this disease. The resistance of the 2 old cultivars may have been naturally selected in marshlands where the disease is endemic. The tolerance of alfalfa to what is commonly called "soil wetness" may be partly due to a better resistance to U. alfalfae.
