GRDC Herbicide behaviour workshop - Horsham

A 1.5-day GRDC supported workshop for agronomists on the science underpinning how herbicides work and its application to field practice. This workshop will focus on the biological pathways and environmental factors that influence herbicide performance, along with interactions that may occur when products are mixed and will be delivered by ICAN Senior Consultant Mark Congreve.

Herbicide resistance is also changing product use. In many situations, products and mixtures that previously worked are now less effective. Participants will leave with a better understanding of the key factors dictating herbicide performance and what can be done in the paddock to ensure weed control is maximised. Knowing what weeds will be controlled from a herbicide application is the easy bit – it’s on the label.

More challenging questions include:

• Why do herbicides perform or fail in some situations? How do environmental factors influence this?
• What can happen when we tank mix?
• Critical comments on the label. Why are they important?
• How do adjuvants and water conditioning agents work? What should be used, when and why?
• How does resistance affect different herbicides? What strategies can be used as resistance emerges?
• How do residual herbicides work and what influences their breakdown?

Workshop numbers will be capped to ensure effective participation. Workshop registrations will be accepted on a first-in basis and a ‘wait list’ will be established for workshops that sell out.

Cost (in AUD$): $275
