Identification of Non-Host Cultivable Crops for Rotylenchulus reniformis

Forty five locally cultivable crops were tested for their respective non-host status against the reniform nematode, Rotylenchulus reniformis under polyhouse conditions. Based upon the egg mass and number of females per plant, fenugreek (Trigonella foenumgraecum), wheat (Triticum aestivum), celery (Apium graveolens), coriander (Coriandrum sativum), mustard (Brassica juncea), cauliflower (Brassica oleracea), lentil (Lens esculenta), carrot (Daucas carota), radish (Raphanus sativus), marigold (Tagetes erecta), onion (Allium cepa), pea (Pisum sativum), chili (Capsicum annum), cabbage (Brassica oleracea), knoll khol (Althaea rosea), garlic (Allium sativum), spinach (Spinacia oleracea), taramira (Eruca vasicaria), maize (Zea mays) and pearl millet (Penninsetum americanum) were found nonhost of R. reniformis in preliminary test. In confirmatory studies wheat (Triticum aestivum), maize (Zea mays), and marigold (Tagetes erecta) were found non-host. However, onion (Allium cepa), mustard (Brassica juncea), coriander (Coriandrum sativum), ajowan (Trachyspermum amoni), taramira (Eruca vasicaria), wheat (Triticum aestivum), cauliflower (Brassica oleracea), paddy (Oryza sativa) were found poor host.
