Germination Ecology of African Lovegrass (Eragrostis curvula) and Herbicide Options for Its Control

African lovegrass (Eragrostis curvula) is one of the invasive perennial grasses that continues to disturb natural ecosystems globally. Experiments were conducted in southeast Queensland, Australia, evaluate effects temperature, salt stress, water burial depth, and sorghum crop residue load on emergence efficacy postemergence herbicides two populations (Clifton Crows Nest) E. curvula. The optimal germination temperature regimes for curvula 30/20 35/25 °C, but seeds did not germinate at temperatures commonly occurring Queensland winter (15/5 °C). Total darkness inhibited by 79%, indicating shade cover effect would reduce Clifton population tolerated a higher concentration sodium chloride (160 mM) osmotic potential (−0.8 MPa). Under both was 31% 20% greater than Nest, respectively, suggesting more tolerant drought stress. maximum obtained surface while declined with increased depth up 4 cm. No seedlings emerged from 8 cm depth. addition amounts Mg ha−1 soil compared no-residue treatment, retention heavy cereal will further delay or restrict emergence. Several found be effective controlling an early stage. Information this study compliment earlier studies targeted management populations.
