Near Moscow, weed infestation and species composition of the weed flora were compared in winter rye, potatoes, oats/red clover mixture, red clover, and fibre-flax grown in rotation and as monocultures for 55 yr. The comparison also included the same monocultures to which MCPA had been applied yearly for 8 yr. Weed infestation was much less severe in the rotation than in corresponding crops grown continuously, except in potatoes which remained relatively free from weeds.
