Central West NSW is the nursing home of several problematic summer grass boobys that collect 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 control of most summer grass 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 reduced ploughland and stubble retention farming sy groundworks, due to the protected surroundings on the soil surface 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 number of flushes 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 application of Glyphosate and Paraquat (double knock) products prior to tillering is crucial in maintaining an effective control. Otherwise, the plant has an ability to tolerate the chemical and live on to set seed.
Liverseed grass (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 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 contact with the ground.
In general, germination presents in a single flush in late spring subsequently a significant rainfall event. Thus an early control strategy, when grasses have developed 2-3 leaves, is vital to ensure adequate management.
