The results of 301 exteriments (1967-2001) on biological evaluation of herbicides in flax cultivation showed a strong correlation between environmental conditions and the efficacy of weed controlling measures.

It was observed that the worse the conditions for flax growth and development were, the more necessary it became to use chemicals in weed control. Therefere, the herbicide doses can be reduced on condition that the level of agronomy is imporoved
