Corn
The crop risk tool provides weather-based forecasting and risk assessments for various crop diseases (including Tar spot, Northern corn leaf blight and Gibberella ear rot) helping farmers to make data-driven decisions. The tool allows users to select the crop, location, planting date and more to create a risk assessment. This tool is supported by Grain Farms of Ontario.
The Canadian Corn Pest Coalition (CCPC) is a collaborative group of experts promoting the proper stewardship of corn pest management technologies. Visit to learn more about entomology, insect resistance management, pathology, and agronomy, and regulatory bodies.
Soybeans
The crop risk tool provides weather-based forecasting and risk assessments for various crop diseases (including White mould and Frog eye leaf spot) helping farmers to make data-driven decisions. The tool allows users to select the crop, location, planting date and more to create a risk assessment. This tool is supported by Grain Farms of Ontario.
The Aphid Advisor decision making tool for soybeans can help determine whether action is required. Advising is based off aphid and natural predator numbers present in the field, along with expected population growth rates to indicate if levels will remain below action thresholds or if action is required.

This guide is a tool to help identify pests that attack field crops early in the growing season. Under each pest, the guide outlines how to identify the pest, explains their life cycle and the damage they cause. It also details scouting techniques, thresholds and integrated pest management strategies including cultural, biological and chemical control. Additional information on protecting natural enemies as well as pollinators is also available at the end of the guide. This guide provides the basics for establishing an integrated pest management strategy for soil borne and early season pests in field crops, which will help target the use of insecticide treated seed to where it is necessary.
This is a guide to wheat diseases affecting heads and grain. It covers diseases visible at head emergence, diseases visible during grain development, diseases visible just before harvest and diseases causing problems in other countries. Learn to recognize common wheat diseases: loose smut, fusarium head blight, stagonospora glume blotch, black chaff, sooty molds, common bunt/dwarf bunt, ergot, and wheat blast.
