外文摘要：Exserohilum monoceras (EM) and Drechslera monoceras (DM) were two potential promise pathgenic fungi for biological control of barnyardgrass (Echinochloa crus-galli (L。) Beauv。)。 Most barnyardgrass seedlings at 1。0～5。0-leaf stage were killed by spraying E。 monoceras and D。 monoceras suspension respectively at dosage of 5。0x10~7 conidia m~2 with 24h dew exposure period。 Treatments of E。 monoceras at 5。4x10~6 and D。 monoceras at 5。9x10~6 conidia M~2 reached 66。1% and 64。4% dry weight reduction of barnyardgrass respectively。 Combination use of E。 monoceras and D。 monoceras with Quinclorac of 5。6mg a。i。 m~(-2) improved a better control of barnyardgrass and reduced the plant height and dry weight of rice seedlings significantly。
