Key to blackleg risk management for your district

Blackleg spore shower risk

Suggestions

Low

Consider applying seed dressing if varieties below MR-MS are sown

Medium

Consider applying recommended fungicide if varieties below MR are sown

High

Consider applying recommended fungicide if varieties below MR-R are sown

In high disease pressure situations seed dressing alone may not be sufficient in providing adequate protection from disease. In this scenario consider applying additional protection either using fertiliser based fungicide or foliar fungicide application. Consider applying foliar fungicide if none of the upfront (seed or fertiliser based) fungicide is applied.
