Active ingredients for increasing pathogen defense in plants and methods for their detection

摘要

The invention relates to methods for finding pathogen defense of plant-inducing compounds, wherein the increase in the expression of one or more plant endogenous genes from the group of jasmonic acid biosynthesis, plant proteinase inhibitors, plant xylanase inhibitors, plant PR proteins (pathogenic Related proteins) and plant chitinases is considered an indication of induction and this use of these compounds alone or in combination with already known against phytopathogenic specifically and directly effective compounds, wherein the application can be carried out either simultaneously or at different times.
