Threats to Wheat Root Health
We previously discussed how root health is key to a successful wheat crop. Let’s take a deeper dive into the many factors that contribute to poor root health and decreased crop productivity:
- Drought. In many regions around the world, cereals are grown in areas subject to short-term drought periods, which leads to troublesome yield inconsistencies.
- Reduced tillage/zero tillage/irrigation. Good land practices favor the prevalence of root diseases.
- Rhizoctonia quickly infects germinating seeds and young seedlings, and nibbles away at root tips.
- Pythium can cause lesions around the root which leads to seedling collapse.
- Fusarium infects the roots and eventually spreads to the crown.
- Wireworms threaten crop yield and quality by attacking root systems.
- Limited crop rotation impacts root health by creating a more hospitable soil environment for diseases and contributes to the “green bridge” effect.
This reinforces the need for strong and fast root development early-on to help ensure enhanced water and nutrient uptake. By incorporating preventive measures – including best management practices and seed treatment applications – growers can help ensure healthy root systems and get their crops started on the right foot.
