Biological efficiency of new substances for the pre-sowing seeds treatment in seedlings protection from infectious lodging

Abstract

Biological efficiency of new substances used for pre-sowing seeds treatment in coniferous plants seedlings protection from the agents of disease of the infectious lodging was established in the laboratory and field studies. It is shown that the new fungicides with a low phyto-toxicity level can effectively restrain the spread of infection. According to the tests results, the substances for pre-sowing seeds treatment were included into the State Register of Plant Protection.
