Abstract. The article presents the phytosanitary rationale of pea crop protection from Fusarium root rot depending on the precursor in Yashkinsky district of the Kemerovo region. It was revealed that pea variety Yamal regionalized in the Kemerovo region and taken as the standard is affected by root rot to a greater extent for crops (19.0%) than for Phytosanitary precursor such as a rape (10.0%). Variety Salamanca has not damage above 11.0% respectively for all precursors. The maximum grain yield was obtained from variety Salamanca for precursor such as annual grasses (rapeseed). The yield was 2.2 t / ha by 0.7 t / ha more than for recognized variety Yamal. As a result of the above it is clear that the choice of variety and the precursor is of great importance in phytosanitary rationale of pea crops protection from Fusarium root rot.
