Soil, seed and crop rotation measures are central; a foliar product is not a universal cure.
- What to look for
- Map uneven wilt, vascular discolouration, root condition, soil history and whether symptoms follow irrigation or field zones.
- When to review
- Investigate early in the season and before widespread canopy collapse; foliar treatment alone may not address a soil-borne complex.
- Role in the program
- Treat the product as one part of an integrated program alongside seed, sanitation, drainage and rotation decisions.
- Evidence to request
- Request pathogen or lab evidence, product specification, approved use pattern and any seed or soil-treatment documentation.
