Summer weeds

Controlling summer weeds is a key strategy to conserving moisture and nutrients for the subsequent crop. This is a common practice implemented across medium to low rainfall cropping zones of Australia.

OFT contains more than 90 trials that have explored issues on managing summer weeds, including herbicide and tillage strategies, the use of herbicides and adjuvants and the latest spraying technologies including spot spraying. Trials covering particular weed varieties include: Awnless barnyard grass, Feathertop Rhodes grass, Liverseed grass, Wild radish, Stink grass and Fleabane. In tackling summer weeds, trials exploring aspects of residual herbicide effects on following crops are also provided.

Aims:

Failure to control annual weed species that persist through cropping phases facilitates replenishment/establishment of weed seedbanks. Consequently, this maintains weed interference in subsequent years of crop production. Harvest weed seed control (HWSC) has been widely adopted in Australia since its inception over three decades ago to prevent r… read more

Aims:

In southern Australian mixed farming systems, there are many opportunities for pasture improvement, providing positive impacts to both cropping and livestock systems. Dryland legume pastures are necessary in low to medium rainfall zones to support productive and healthy livestock, along with optimal production in crops following these pastures. … read more
