It’s a frustrating challenge for producers and breeders, but there are practices and management techniques that growers can employ to ensure a good return on investment for their soybean production.SIL’s new course, the Soybean Rust Crash Course, is designed for growers, practitioners, breeders, and researchers to learn how to identify the disease, scout for disease at the optimal stage, and manage the disease before it’s too late.  The Soybean Rust Crash Course is free and includes four modules: 1. The Pathogen and symptoms; 2. Scouting; 3. Management; and 4. For breeders and researchers, more information on data collection and varietal resistance.Module 3 covers disease management and includes a Rust Spray Calculator, designed to aid in environmentally responsible and economically feasible decision-making on whether or not fungicides should be used to control rust outbreaks. The calculator bases recommendations on growth of the crop and rust pressure, and then determines the economic gain that can be achieved by considering a grower’s local fungicide cost, labor cost, and grain price.  The Rust Spray Calculator provides growers with evidence-based decision making on whether they should use fungicides to control rust observed in their fields. The importance of scouting a field from beginning bloom to full seed development cannot be overemphasized. Finding the disease before it takes over provides an opportunity to spray with fungicide and save up to 80% of yield. The Soybean Rust Crash Course, combined with the Rust Spray Calculator, provides specific recommendations for growers, from scouting techniques and identification of soybean rust, to analyzing the potential economic benefits of spraying. For breeders and researchers, the course goes into more depth about plot-level data collection and the current state of varietal resistance.Successful completion of the Soybean Rust Crash Course will result in a Certificate of Completion that can be shared on LinkedIn, Twitter, and Facebook. SIL’s Disease Management program has several other resources that complement the new Soybean Rust Crash Course and Rust Spray Calculator including: The Field Guide to African Disease, Pests, and Nutrition Deficiencies The Guide to African Soybean Seedborne Diseases and Pests The Soybean Rust Disease Bulletin The Soybean Innovation Lab Disease and Pest ID Board on Facebook The Rust Hot Spot Map – see below You can find several other free courses at SIL-University  The Tropical Soybean Information Portal (TSIP) features a Rust Hot Spot Map. The map is a tool containing trial and operator information on rust disease incidence and severity over seven seasons and 57 locations.
