Herbicide Resistance Management

Be Cottonwise
In the use of weedmaster® DST® in glyphosate tolerant cotton

Gain the full benefits of weedmaster DST by completing our easy online training to gain accreditation, and start lodging your Cottonwise Field Survey when you spray weedmaster DST

With the new registration of weedmaster DST for over the top use in glyphosate tolerant cotton, Nufarm have developed the Cottonwise® program where you, your advisor or TSP can manage applications of weedmaster DST.

The registration of weedmaster DST (and all registered glyphosate products) for over the top use in glyphosate tolerant cotton crops is granted by the Australian Pesticides and Veterinary Medicines Authority (APVMA). As a condition of registration, the APVMA requires that all users and potential users are familiar with the correct use of weedmaster DST and follow up weed management procedures in the event of weed escapes.

Information captured through the Cottonwise program and Cottonwise Field Surveys is used by Nufarm to assist research and identify issues regarding the development of weed resistance.

To start recording your use of weedmaster DST, simply click on the Be Cottonwise button below and start logging your usage. For returning visitors, click log in at the top right hand corner.

If you are unsure of your resistance status, prior to using weedmaster DST you or your advisor should conduct a herbicide risk assessment using an online assessment tools such as WeedSmart or the QDAFF’s online Glyphosate Resistance Toolkit.
Nufarm has developed a range of guides and specnotes designed to help get the most from your cotton crop. Click here for the latest information.
