Establishing a Stand Use well-drained sites for alfalfa. This minimizes disease pressure during establishment as well as over the life of the stand. Alfalfa seed is small and requires a firm, moist seedbed for proper germination and establishment. Inoculating alfalfa seeds with the proper rhizobia is also critical. Alfalfa seeds and seedlings are subject to attack by a variety of organisms, primarily fungi, which can affect seed germination and seedling emergence and vigor.
Several fungicides are available for treating seed prior to planting.
Some fungicides can be applied directly by the producer, while others must be applied commercially. Some commercial alfalfa seed can be obtained with a fungicide already applied. Rots Managing alfalfa for maximum vigor is important in minimizing damage from root and crown rots. In any given area, select a cultivar with sufficient winter hardiness. Lack of winter hardiness and associated winter damage open lead to root and crown rot problems.
