Bio-based Seed Treatment – For Growth and Yield Potential

Rising GM seed prices and cost effectiveness of seed treatments over other crop protection methods are expected to drive the demand for the seed treatment market in the near future. However, an absence of centralized government regulations for treated seed and seed treatment active ingredient registration are expected to hamper the growth and demand for seed treatments in the next five years.

Biological seed treatment is an affordable and effective way to optimize seed germination, plant establishment, and early growth and yield potential. It is also one of the lowest financial investments a grower can make to maximize productivity and improve the bottom line.

Seed treatments can colonize plant roots and send out filaments into the surrounding soil. These filaments form a bridge that connects the plant roots with large areas of soil (up to 200 times larger than the root zone) and act as a "pipeline" to funnel nutrients to the plant. In return, the plant discharges compounds, through its roots, to stimulate fungal growth. The efficacy of the fungi is also enhanced by soil microbes such as bacillus sp. These bacteria, many of which are aerobic, affect root colonization and function by producing vitamins, hormones, and other compounds that promote fungal growth.

Once the seed is planted, it is important that germination occurs uniformly and quickly. If the soil is too cold, germination can be delayed. This can result in seed damage and uneven emergence and, in certain cases, re-seeding may be necessary. Seed treatments are effective against problems that occur in cold wet soils especially limited disturbance and no-till operations and it areas of low moisture. Seed treatments are also effective against a broad spectrum of problems including seed decay, seedling diseases and soil pathogens.

Natural seed treatments can make less available forms of soil phosphate available to plants, promote nitrogen fixation, root development and quick emergence, stimulate cell division and increases stress tolerance. In addition, seed treatments can increase the vigor of treated plants helping them resist damage by pathogenic fungi and damping off. Typically, this results in (1) early root growth and larger roots (2) a more consistent plant stand and increased yields. Larger roots provide better access to moisture and nutrients which translates into improved health throughout the life cycle of the crop.
