draft revised 26 Feb, 2020

The Northcentral Integrated Pest Management Center – Pulse Crop Working Group has developed the following information on fungicide efficacy for management of widespread seedborne and soilborne diseases of pulse crops (peas, lentils, and chickpeas) for use by the pulse production industry in the United States. Efficacy is based on labelled application rates according to label instructions and the presence of disease. Table includes the most widely marketed products, and is not intended to be a list of all labelled products.
