Herbicide Resistance Testing

Weed herbicide resistance is becoming an increasing problem within agriculture. With such a large spectrum of chemicals available it is important that herbicide use is managed to ensure continued efficacy. Certain bodies such as the Farrer Centre at Charles Sturt University specialise in the  identification of resistant weed seed supplied from your paddock/crop.

IK Caldwell can collect samples, provide interpretation of the results and advise the best strategy to overcome any resistance issues that may arise.

Below are some graphs taken from the 2006 Farrer Centre report. To view a copy of the full report click here
