Published April, 2021.

This table presents information on available fungicide products for management of widespread seedborne and soilborne diseases of pulse crops (peas, lentils, and chickpeas) for use in the United States.  The information is based on labelled application rates according to label instructions and the presence of disease.  The table includes the most widely marketed products and is not intended to be a list of all labelled products nor is it an endorsement of any specific product.  Consulting this table does not substitute careful reading of the product label before an application is made.
