Field & forage crops
A productive stand starts with roots and continues through each cutting.
CROP PRIORITIES
Pests, diseases and growing conditions can produce similar symptoms. Connect field history and diagnosis with the crop stage before choosing an input.
Aphanomyces root rot can damage fine and lateral roots, leaving alfalfa seedlings stunted and yellow. Waterlogging and disease may occur together. Review drainage and seek diagnosis before treating yellowing as a simple nutrient deficiency. Variety resistance should reflect the locally relevant pathogen races and the field’s history of establishment failure.

Wet areas with recurring stand loss need particular attention. Drainage, resistant varieties and healthy establishment support long-term stand survival; persistent root damage should be assessed before decisions on further inputs or stand renewal.

From establishment to harvest or renewal, the purpose of crop management changes with each stage.
Stand establishment depends on seed quality, soil condition and crop-matched inoculation. A uniform stand provides the foundation for subsequent forage production.
Root and crown development support the perennial stand. Consider biological nitrogen supply together with other nutrients, drainage and soil condition.
Cutting decisions balance forage quality with crop recovery. Biological inputs complement a considered harvest and nutrition programme.
Between cuts, monitor regrowth and stand condition. Water, nutrition and root health remain connected through the life of the stand.
BIOLOGICAL INPUTS
These products have distinct roles in nutrition, root development and crop management. For a pest or disease, product selection also requires evidence for the identified target and applicable market label.
