Crop Disease Management • Sufficiently large amounts to prevent food shortage • Free of diseases • Customer demand • Quarantines • Shipping and storage • Free of residues • Limit environmental harm • Profitable for grower but affordable for consumer The Dilemma

Slide 18

Slide 18 text

Why a DSS? What does it offer? • Alternative to calendar spray programs • Enhance timing of fungicide sprays to disease development • Economic benefits (spray reduction) • Environmental benefits (spray reduction) • Resistance management strategy
