Action thresholds have not been identified for all disease and insect risks in field peas, so the recommendations provided are based on thresholds from similar crops, identified action thresholds for field peas, or rules of thumb.
Understanding seed quality and applying seed treatments to pulse seed when disease or insect risk is present is critical to maximizing yield.
Fungicide seed treatments protect the seed and seedlings from soil-borne diseases, as well as those diseases found on the surface of the seed or carried inside the seed. Seed treatments will not cure seed with high disease levels or poor quality.
For a seed treatment to provide effective protection, it is important to ensure adequate seed coverage and appropriate rates for the target pest(s).
Seed treatments will break down as the plant begins to develop, and as a result, their protective effect on the seed will only last for the early part of the plant’s growth.
When using a seed treatment in combination with an inoculant, it is important to check with the inoculant manufacturer to ensure compatibility with the seed treatment before use.
A treated seed may pose a risk to other organisms or plants in the environment. Dispose of all leftover treated seed properly, and do not leave treated seed on the soil surface.
