A thorough understanding of how herbicides work assists agronomists and growers to maximise herbicide performance. When confronted with a range of weed problems and environmental conditions, the challenge is to optimise the results in the field.
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?
- Critical comments on the label. Why do they exist and how were they developed?
- 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?
ICAN is delivering a series of GRDC supported workshops for agronomists on the science underpinning how herbicides work and its application to field practice. 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.
Workshop outline
Workshops are customised for each location to focus on regionally important herbicides and management issues under the following structure.
- How herbicides work – disruption of key enzyme systems within the plant
- Leaf entry of post-emergent herbicides. Including the influence of environmental conditions and the importance of adjuvants
- Post-emergent herbicide translocation and metabolism
- Herbicide resistance and resistance mechanisms
- Maximising performance of the key post-emergent modes of action (MOA's)
- Pre-emergents –
- Stubble, volatilisation, photodegradation and incorporation
- Relationship with soil type and soil moisture
- Degradation, plantbacks and crop safety
- Impacts of tillage and planter type
- Maximising performance of key pre-emergent herbicides
These small group workshops run for 1.5-days. Numbers are limited to ensure active participation and discussion. Previous workshops have ‘sold-out’, so early registration is essential.
While the workshop content is targeted to experienced agronomists, interested growers are welcome. Cost is $165 ($150 + GST) per workshop.
