2 Disease Fungicide Decision Tree for Corn and Soybean Crop and field history Continuous corn/soybean; short rotation corn- soy- corn Disease last year; crop residues inoculum for infecting this year s crop; no- til & strip- til Hybrid/variety selection & weather Susceptible to moderately resistant hybrids and varieties Favorable environment heavy dews, frequent rainfall, high humidity, moderate temperatures Early and/or multiple infection periods Yield Goal Maximize yields Corn 1- application timing: VT R1 2- apps: V10 followed by VT R1 (inbreds, susceptible hybrids, early season infections) Soybean Foliar diseases: R3 White mold: R1

3 Active Ingredients Aproach Prima (cyproconazole+ picoxystrobin) Headline AMP (metconazole+ pyraclostrobin) Priaxor (fluxapyroxad+ pyraclostrobin) Fortix (flutriafol+ fluoxastrobin) Fungicides for control of Corn and Soybean Diseases Label Flexibility C, S, W C C, S, W Triazole Protectant, systemic, curative, eradicant Less systemic movement into leaves SDHI- fungicide (group 7), not a triazole. Poor Cercospora and NCLB control compared to triazoles C, S, W Protectant, systemic Attributes Strobilurin Rapid uptake, systemic, curative, translaminar & redistribution within the canopy, excellent plant health Excellent plant health, not curative, less systemic Excellent plant health, not curative, less systemic Plant health effects not known, little direct performance comparisons to high performing strobilurins C=corn, s=soybean, w=wheat. NCLB=Northern corn leaf blight

NCLB=Northern corn leaf blight

6 Aproach Prima - Preventive, Curative, and Eradicant preventive Controls disease when applied before infection only no effect on established disease. Uniform spray coverage often critical. infection residual Extended protection after a fungicide application. curative Controls disease when applied after infection but before visible symptoms aka kick back. Control may range from 1 up to 7 days depending upon disease progression within the plant and the specific fungicide. antisporulant Inhibits spore production or viability, with or without affects on development of established lesions. Fungicides do not have to move into the plant to be an antisporulant. eradicant Controls disease when applied after appearance of symptoms. Requires inhibition of lesion size, spore production, spore viability or some combination.

7 Aproach Prima Curative and Eradicant Activity Wheat was infected with rust and Aproach Prima was sprayed either at 2- days after inoculation (curative) or 4- days after inoculation (eradicant). Rated for performance 9- days after inoculation. Treatment 48- hr Curative 4- day Eradicant Nontreated 0% 0% Aproach Prima 6.8 fl oz 100% Control 100% Control Aproach Prima is: Preventive - stops spore germination and penetration, spore- kill. Curative - stops the fungus from completing its life cycle even after initial infection. Eradicant - stops the sporulating lesion to shut down the epidemic.

16 DuPont Aproach Prima fungicide safeguards the full potential of your elite genetics. Aproach Prima protects your crop, even under heavy disease pressure, while providing foliar health benefits which keeps leaves greener for improved grain quality and yield. Key Benefits of Aproach Prima: Two premiere modes- of- action for better disease control of many hard- to- control diseases, including: Southern rust, Northern corn leaf blight, grey leafspot Frogeye leafspot, Cercospora blight, soybean rust Increased green leaf area keeps the photosynthetic energy producing longer into the season which contributes to improved seed development, test weight, and quality Higher yields for profitability
