What captured our imagination?
Paddock - Crop Disease App - Paddock
Resistance is the key to integrated management.
Screen 60,000 wheat lines for disease resistance.
App is part of a multi-faceted extension program.
Crop diseases cost Vic. $120
million per year.
Aims - Pilot Project
Increase the use of resistant varieties and reduce chemical use.
Enabling agronomists and farmers to compare the diseases resistance
