We  studied the root   nodulating and nitrogen fixing symbiosis between  bacteria from the   genus Methylobacterium and C. glaucoides, C.  perrottetii and C.   podocarpa. These three Crotalaria are nodulated by   Methylobcaterium nodulans, a facultative  methylotrophic bacteria   able to both nodulate and fix nitrogen.Then we  screened the   biological activity of the three Crotalaria species  plus twelve others   on major root-knot nematodes parasitizing plant  crops. All are   resistant to main root-knot nematodes as Meloidogyne  species.   Aqueous leaf and root extracts from most of these  legumes   reversibly paralyse second stage juveniles,  suggesting a high   nematostatic potential to be used as green manure.  Agronomic tests    indicate that the culture of most of these Crotalaria  as their   ploughing in green manure, strongly reduce the  dominant nematode   populations protecting efficiently a sensitive  vegetable crop. All   these results suggest promising uses of these legumes  in agriculture   as natural alternative to chemical nitrogenous  fertilizers and   nematicides.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786131549137\"\u003e\u003ch3\u003eLES LEGUMINEUSES DU GENRE CROTALARIA: SYMBIOSE FIXATRICE D'AZOTE ET ACTIVITES BIOLOGIQUES CONTRE LES  NEMATODES PHYTOPARASITES\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9786131549137","offer_id":40148925415517,"sku":"9786131549137","price":69.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/6c270d76-308e-4b3e-8ae9-744e9f081e27.jpg?v=1761026638","url":"https:\/\/shop.autorenwelt.de\/products\/les-legumineuses-du-genre-crotalaria-von-philippe-jourand","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
