ID your weeds: new CRDC-supported weeds app out now! (18 Jan 2019)

A new weed identification mobile app has been released. Weeds of Australian Cotton is a tool for cotton growers and their advisors, designed to assist in identifying 50 key weed species. It was developed as part of a CRDC-supported project led by Dr David Thornby, with input from fellow weeds experts Graham Charles, Jeff Werth and Dr Ian Taylor.

“Weed identification in early growth stages is critical as similar-looking species often have quite different control requirements, and waiting for diagnostic features like flowers and fruits to appear means the optimal window for herbicide applications has long passed,” David said.

“For this reason, the Weeds of Australian Cotton key includes cotyledon shapes as an important diagnostic character.

“It is important to note that weeds not included in the key could be present in cotton fields, and misidentification is possible. Confirming identification with an expert is advised, especially if the weed is proving hard to kill.”

“Building on previous publications, we now have a way to ID weeds on the go especially in areas where cotton is relatively new, that’s really useful,” CottonInfo Weed Management Technical Lead Eric Koetz said.

“It has a biosecurity role to identify new weed species – if you are seeing something on your farm or elsewhere that isn’t on the app – contact us.”

The app is available for both mobile operating systems - via the Apple App Store or Google Play.
