SUMMER GRASS WEED ID Central West NSW is the nurse home of several problematic summer eatage boobys that draw in early pull strings to reduce the impact on consequent winter crops. Impacts of these weeds include; impeding on wet conservation, tie up of nutrients and competition with early ingrained crops. For fatten out train of most summer break species, an integrated weed management strategy must be implemented. Barnyard deceive (Echinochloa spp.) universe of discourse growths of Barnyard Grass have been favoured by the introduction of cut ploughland and stubble retention acres sy groundworks, due to the protected surroundings on the soil break through where the seed is placed. Heavy credence on chemical control in these systems has led to underground issues. Barnyard Grass is a fecund seeding plant and exhibits a hale seed dormancy, which ensures a account of extremumes of seeding events over consecutive summers. The distinguishing features of Barnyard Grass are a purplish base, hairless stem, no ligules (collar where the snap joins the stem) and white seeds. Chemical screening of Glyphosate and Paraquat (double knock) products prior to tillering is crucial in maintaining an effective control. Otherwise, the plant has an strength to tolerate the chemical and live on to set seed.
Liverseed crap (Urochloa panicoides) Similarly to Barnyard Grass, Liverseed grass populations have been favoured by the introduction of reduced tillage and stubble retention. The main optical characteristics differing Liverseed Grass from Barnyard grass is a broad, pal e yellow-green thumb with hairs present on ! leaf margins and sheaths. The stem lies flat with the maturation ends bending up into an erect position, with roots developing where stem nodes come into intimacy with the ground. In general, germination presents in a single flush in late spring subsequently a probatory rainfall event. Thus an early control strategy, when grasses have developed 2-3 leaves, is vital to ensure adequate management.
