Kajian Tanaman Inang Nematoda Puru Akar Padi (Meloidogyne graminicola)

Abstract

The objective of the research was to study host plants or alternate hosts of root-knot nematode of rice ( Meloidogyne graminicola ). At the first phase research, ten rice cultivars were inoculated with M. graminicola . On the second phase, nineteen species of plants were treated with M. graminicola . Both experiments were done in green house in Completely Randomized Design. The third phase research was conducted as a survey method using “proportional random sampling”, with D.I. Yogyakarta as its survey areas. The research results indicated that all rice cultivars tested were attacked by M. graminicola . The lowest number of root-gall was found in IR 26. Of the 19 species plants tested, soybean, pea common bean, france bean, cabbage, and sugarcane var. Ps 56 were attacked by M. graminicola . The survey results indicated that 15 species of weeds were invaded by M. graminicola , i.e. Coix lacrymajobi , Comelina nudiflora , Cyperus flavidus , C. iria , Echinochloa colona , Eragrotis amabilis , Fimbristylis pilosa , Ichaimum mutichum , Leersia hexandra , Ludwigia adscendens , L. peruviana , Marsilea crenata , Monochoria vaginalis , Polygonum barbatum , and Stagnima sp. The highest populatiom of M. graminicola was found on E. colona . Key words: host plants, Meloidogyne graminicola
