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:

In 2018, a number of grower network meetings concluded that correct identification of summer weeds and their management was an important local issue. It was also identified that new species of summer weeds are becoming more prevalent and control is becoming problematic and costly. In response, the summer weed survey of WA cropping districts comm… read more
