TAGETES: NEMATODE UNFRIENDLY MEDICINAL, ORNAMENTAL PLANT PUBLISHEDIonică Prohab, Ioan Borcean None
Tagetes patula (common name marigold) has been cultivated for its receptacleless flower (Tagetes flos sine receptaculis) containing volatile oil (0.5-1.5%) helenine, a substance used in medicine for the quick adaptation of the eye to different light intensities. In Germany, they pay a lot of attention to this plant for the nematode control properties of the roots. In this paper the authors present the results of their research carried out between 2006 and 2008 on a gleyed aluvisoil in the Timişului Plain located in Western România. The goal of the research was to control nematodes in vegetable gardens by cultivating Tagetes patula and Tagetes erecta species in alternation with vegetables. Results are original and particularly important in Pratylencus nematode control in vegetable gardens within ecological technologies (no insecticides). Results point out the possibility of controlling Pratylencus nematodes (40-70%) depending on the Tagetes species used.
