Radish defensibility enhancement against Rhizoctonia solani was tested for 11 products or product combinations.In the first phase, two laboratory experiments were performed. Firstly, antagonistic effects on Rhizoctonia ofthe products was tested on petri dishes inoculated with Rhizoctonia. Secondly, treated radish seeds were placedon petri dishes with Rhizoctonia. Subsequently a pot experiment took place in which the soil was inoculatedwith Rhizoctonia and was treated with the products. Infection by the fungus became quickly visible duringgermination. However, no differences in germination and fresh weight at harvest were found compared to theuntreated reference, except for the control and Rizolex treatment. Other ways of product application or differentimplementation in the growing strategy may change the results. In het onderzoek naar weerbaarheidsverhogende middelen in radijs tegen Rhizoctonia solani zijn 11 middelen ofmiddelencombinaties getest. Eerst vond er een laboratoriumproef plaats waarin de antagonistische werking vande middelen op Rhizoctonia getoetst is. Vervolgens zijn behandelde radijszaden op petrischalen met Rhizoctoniagetoetst op kieming. Daarna heeft er een potexperiment plaatsgevonden waarbij de grond besmet is metRhizoctonia. Besmetting was tijdens de kieming al waarneembaar. Er waren kleine verschillen in de kieming,maar uiteindelijk was er geen behandeling waarbij de infectie minder was dan bij de besmette controle. Wellichtkunnen andere toepassingsmethoden of aanpassingen in de teeltstrategie hier verandering in brengen. |
