The effect of the chemicals on pathogen development &lt;em&gt;in&amp;nbsp;vitro&lt;/em&gt; and &lt;em&gt;in planta&lt;/em&gt; was analysed. Both chemicals were shown to protect plants from the pathogen. &lt;em&gt;In vitro&lt;/em&gt; assays showed that asexual reproduction was sensitive to both chemicals. However, mycelial growth and sexual reproduction, which were clearly sensitive to metalaxyl, were sensitive only to high concentrations of fosetyl-Al. Fosetyl-Al and metalaxyl had almost the same efficacy when applied preventively by soil drench to seedlings. This difference between &lt;em&gt;in&amp;nbsp;vitro&lt;/em&gt; and &lt;em&gt;in planta&lt;/em&gt; results can be attributed to the dual action of fosetyl-Al, not only inhibiting the pathogen but also stimulating host defence. In adult trees, preventive and curative treatments were tested, but only the fosetyl-Al preventive treatment was effective in the assayed conditions. Interestingly, seedlings pretreated with both fungicides were less susceptible to the effectors secreted by the pathogen. Our results indicate that fosetyl-Al and metalaxyl provide some resistance to the plant besides the fungistatic direct action on the pathogen. Further studies to elucidate a possible resistance-inducing activity of these chemicals and the mechanisms involved are underway.&lt;/p&gt;</style></abstract></record></records></xml>
