The MyCrop App enables you to diagnose wheat production constraints while in the field.At the centre of MyCrop is an intuitive diagnostic key, which quickly diagnoses a range of possible constraints based on real-time crop and paddock symptoms.The app also contains an extensive image and factsheet library for 90 in-crop wheat constraints - helping users to accurately identify constraints and determine possible management solutions.MyCrop covers a broad range of wheat diseases, pests, nutrient deficiencies, herbicide damage symptoms and other management and environmental production issues.Canola and barley production constraints will be added to the app soon.
