Adelaide’s heat wave definitely made itself known last week — and not just to us. With hot weather policies in place, some of our regular practical activities had to be adjusted to keep everyone safe. While that changed how things ran, it actually turned into a really valuable learning opportunity.
The extreme heat placed significant stress on plants, making them far more vulnerable to pests, diseases and physiological disorders. This gave us the chance to see problems developing in real time and work through how to identify and manage them, rather than learning about them only in theory.
We were able to complete practicals at St Laurence’s Priory and the National Wine Centre of Australia, which exposed us to different landscapes, plant types and growing conditions. Each site presented its own set of challenges and a wide range of issues to investigate, keeping our observations and discussions both varied and practical.
Student Pest Management Tips
Based on what we observed during the heat wave practicals, here are some important pest management tips to take away:
- Monitor early and often: Regular inspections help catch pest and disease issues before they become severe, especially during periods of plant stress like heat waves.
- Know your beneficials: Not all insects are a problem. Identifying beneficial organisms can help reduce unnecessary chemical controls.
- Stress makes plants vulnerable: Heat, water stress and nutrient imbalance can all increase pest and disease pressure — healthy plants are your first line of defence.
- Use thresholds, not panic: Just because pests are present doesn’t always mean action is needed. Assess damage and treatment thresholds before intervening.
- Choose the least‑impact option: Start with physical, cultural or biological controls where possible before moving to chemical options.
- Wear your PPE: Even simple treatments require correct PPE to protect yourself and others.
- Record everything: Good records help track what worked, what didn’t and inform better decisions next time.
- Be flexible: If a control method isn’t working, adjust your approach and reassess — pest management is an ongoing process.
Although the heat made the week challenging, it highlighted just how closely environmental conditions and plant health are linked. More importantly, it showed how practical, adaptable pest management skills are essential out in the field.
What started as a tough weather week turned into a valuable hands‑on learning experience, giving students real insight into managing plant pests, diseases and disorders under realistic conditions.
