One or two applications of one of the newer generation pyrethroids, alpha-cypermethrin, was effective in controlling CMV in lupin on one occasion by suppressing virus incidence in experimental plots by up to 62%, which surpassed the effect of other insecticides (Jones, 2001). However, application of alpha-cypermethrin did not always effectively control CMV spread. Use of resistant cultivars and cross protection The simplest measure of control would be the use of cultivars with resistance to the principal crop viruses.
