| A method for testing the efficacy of products which improve the resistance of plants was developed in the Julius Kühn-Institute. The susceptible radish (Raphanus sativus) cultivar ´Saxa 3` was infected with Peronospora parasitica isolated in the field. Different plant resistance improvers (PRI) like plant or algal extracts were tested compared to aqua dest. as control and ß-aminobutyric acid (BABA) as a standard. PRI were sprayed twice on intact plants (BBCH 10: Cotyledons completely unfolded; growing point or true leaf initial visible). 24 h, 48 h or 72 h after the last application with PRI, the plants were inoculated with P. parasitica. 10 to 14 days after inoculation, the concentration of spore suspension from cotyledons was determined. The efficacy of... |
