Two possible examples (among many) are described below.
Plant disease: Wheat rust
- Wheat rust is a fungal disease that produces reddish-brown pustules on wheat stems and leaves, weakening the plant and reducing grain development.
- This disease can devastate entire wheat crops, significantly reducing grain yields and causing major economic losses for Australian grain producers.
Plant disease: Stone fruit scab
- Caused by fungi, produces dark spots on plums, peaches and nectarines that develop into scabs, potentially cracking and destroying the fruit.
- This disease significantly impacts crop quality and yield, resulting in economic losses for farmers.
