Identification

This training program was created to help the user identify symptoms of leaf diseases on oilseed rape.

The presence of a breed-specific resistance to downy mildew in a sunflower genotype is shown by a laboratory test. Depending on the breeds of Plasmopara halstedii and the resistance sources, the resistance is caracterised by an absence of sporulation (class R) or a slight sporulation (class RII). This last syndrome is frequently mixed up with a sensitivity presenting a limited sporulation (class SII). The present training program aims at helping you distinguish between plantlets of class SII and RII.

La reconnaissances des adventices, surtout au stade plantule, étant une des principales difficulté de mise en œuvre des protocoles de quantification des adventices, le projet CASIMIR propose deux didacticiels d’autoformation à la reconnaissance des adventices.
