Flax Sickness

sharp reduction in flax yields when it is raised continuously or frequently on the same field. It is caused by the accumulation of soil microorganisms, especially parasitic fungi, which are harmful to the flax, by one-sided depletion of the soil, and by the development of specific weeds, such as hardy ryegrass (Lolium remotum) and flax spurry. Steps to combat flax sickness are proper crop rotation and raising flax varieties that are resistant to flax sickness.
