Welcome to the Saskatchewan Disease Risk and Environmental Heatmaps, developed through a partnership between Saskatchewan Pulse Growers and Ukko Agro Inc.
These maps provide weather-based insights to support producers and agronomists across Saskatchewan, with a focus on forecasted risk assessments of lentil Anthracnose and chickpea Ascochyta, alongside key environmental and climate conditions. Using data from a 20 km grid of virtual weather stations with hourly inputs (sourced from IBM/The Weather Company), the system generates regularly updated maps that evaluate how recent and forecasted weather conditions influence disease development and environmental risk factors.
Disease risk maps are designed to identify areas where environmental conditions are conducive to disease development, based on factors such as temperature, humidity, and precipitation. It is important to note that these maps reflect weather-driven risk only—they do not account for crop stage, pathogen presence, host susceptibility, or field-specific conditions such as irrigation, which may create localized microclimates and alter risk levels.
Environmental and climate heatmaps are provided in parallel to support broader agronomic decisions and general crop management under variable weather conditions.

Lentil Anthracnose Risk Maps: Agronomist Notes
- As of June 15th 2026, lentil Anthracnose risk is high across most of the province due to steady moisture throughout the season so far.
- Slightly lower risk in the northeast region of the province as of June 15th.
- Significant rain this week will increase the risk of Anthracnose and most of the province will be considered high risk with the exception of a few pockets in the southern regions.
Chickpea Ascochyta Risk Maps: Agronomist Notes
- As of June 15th 2026, chickpea Ascochyta risk is medium across much of the province. The risk is high across the eastern part of the province and a few areas in the southwest.
- The risk increases slightly across the central part of the province throughout the week as precipitation is anticipated across much of the province.
- The northeast region remains at low-medium risk throughout most of the week.
Temperature Maps: Agronomist Notes
- Moderate temperatures across Saskatchewan (max ~20–25°C for most of the province, avg ~10–20°C) support vegetative growth in pulse crops.
- Cooler conditions in the southeast region (15-20°C) will slow crop development but reduce early-season stress.
- No widespread heat stress risk, though localized warmer pockets could increase moisture demand in the southwest region.
Precipitation Map: Agronomist Notes
- Scattered precipitation across most of Saskatchewan supports continued emergence and plant stand.
- Areas in the southeast could receive up to 25 mm of rain with a few pockets receiving up to 30 mm, which elevates the risk of root rot and foliar diseases.
- Most of the province will be in the moderate range of 5-15 mm of precipitation. This supports early season growth and even plant stands.
Growing Degree Days Map: Agronomist Notes
- Most of Saskatchewan is at ~300-400 GDD since May 1, supporting steady early-season growth.
- Southern and eastern regions are slightly ahead, pushing crops further into vegetative development.
- Overall GDD accumulation remains moderate, keeping crops in early vegetative stages where moisture availability and disease pressure can cause yield impacts.
While every effort has been made to ensure the accuracy of these maps, weather-driven models are inherently uncertain, and forecasts may not be 100% precise. All outputs are based on conditions at the time of modeling and are subject to change as weather patterns evolve.
These maps are intended to serve as general decision-support tools only. They should not be relied upon as the sole basis for disease management, spray decisions, or other operational actions. Disease development and crop outcomes may be influenced by local environmental conditions, crop management practices, varietal susceptibility, and other factors not captured in the models. Users are strongly encouraged to verify risk through field scouting, on-site observations, and consultation with qualified agronomic advisors. For disease-specific decisions, refer to additional resources such as fungicide decision support tools and field-level risk assessments.
