Grasses

SUMMER GRASS WEED ID Central West NSW is the care for home of several problematic summer stag boobys that see 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 planted crops. For fatten out fit of most summer spate 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 reduce ploughland and stubble retention body politic sy groundworks, due to the protected surroundings on the soil bob up where the seed is placed. Heavy credence on chemical control in these systems has led to underground issues. Barnyard Grass is a prolific seeding plant and exhibits a hale seed dormancy, which ensures a shape of floodes of seeding events over consecutive summers. The distinguishing features of Barnyard Grass are a empurpled base, hairless stem, no ligules (collar where the snap joins the stem) and white seeds. Chemical coat of Glyphosate and Paraquat (double knock) products prior to tillering is crucial in maintaining an effective control. Otherwise, the plant has an great power to tolerate the chemical and live on to set seed.

Liverseed dummy (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, pale yellow- green thumb with hairs present on leaf marg! ins and sheaths. The stem lies flat with the maturation ends bending up into an erect position, with roots developing where stem nodes come into tangency with the ground. In general, germination presents in a single flush in late spring subsequently a earthshaking rainfall event. Thus an early control strategy, when grasses have create 2-3 leaves, is vital to ensure adequate management.
