A condition, known locally as "alfalfa sickness," is prevalent in cutover forest and adjacent
prairie areas of eastern Washington and northern Idaho. Alfalfa sickness, characterized by
unthrifty, spindly, chlorotic plants, results in low alfalfa production (figure 1).

Alfalfa sickness exists in areas with recorded histories of good alfalfa production verified
by the fact that some fields show good legume growth, as do isolated patches or even individual
plants in otherwise unthrifty stands. Furthermore, the evidence of good growth along fence rows,
the bottoms of hills, fill areas, burn rows, and road ditches indicates that good growth in the
area is possible.
