Abstract
Allelopathic activity of Cyperus iria root toal alkaloids with Nicotiana tabacuml,Oryza sativa,Plantago asiatica,Eclipta prostrate,Bidens pilosa and antifungal activity with Magnaporthe grisea,Sclerotinia sclerotiovum,Alternaria solani,Gibberella saubinetii,Dothiorella gregaria and Physalospora piricola were studied by bioassay.The results suggested that C.iria root total alkaloids did not significantly inhibit the seed germination of O.sativa and E.prostrate at 250~4000μg/mL,but significantly inhibited seedling height of N.tabacuml;seedling root length,height and fresh weight of O.sativa and seedling height of E.prostrate were significantly inhibited only at 4000μg/mL,but at lower concentrations,total alkaloids showed significant inhibition on seedling root length,height and fresh weight of N.tabacuml,P.asiatica,B.pilosa and seedling root length and fresh weight of E.prostrate;Growth of G.saubinetii were not significantly inhibited by C.iria root toal alkaloids at 25~400μg/mL;but at 100 ~ 400μg/mL for S.sclerotiovum,200~400μg/mL for M.grisea,A.solani,P.piricola,400μg/mL for D.gregariaat,the growth of these five strains were significantly inhibited,at 400μg/mL,the inhibition rates for them were 40.10%,20.54%,30.63%,34.82% and 12.08% respectively.It could be concluded that C.iria root total alkaloids have the potential for development as biopesticides.
