Protect Soybeans From Resistant Frogeye Leaf Spot

The dual modes of action in Aproach® Prima provide control of frogeye leaf spot in soybeans while enhancing resistance management and efficacy.

Frogeye leaf spot favors warm, moist conditions. Left untreated, the disease can reduce soybean yield as much as 10 to 30 percent.

Diligent scouting and appropriate preventive action or treatment when needed will help prevent yield losses due to frogeye leaf spot. Watch this video to learn how to identify frogeye leaf spot and control it with DuPont Aproach® Prima fungicide.

Frogeye Leaf Spot Risk Factors

  • Fields with a history of frogeye leaf spot
  • Temperatures of 77 to 85 F
  • Frequent rainfall events
  • High relative humidity (>90 percent)

Control Strategies for Resistant Frogeye Leaf Spot

Strobilurin-resistant strains of frogeye leaf spot have been identified in several states, including Arkansas, Kentucky, Illinois, Tennessee and Missouri. Growers concerned with resistant frogeye leaf spot can apply 6.8 fluid ounces Aproach® Prima fungicide.

Aproach® Prima has two premier modes of action for better disease control of many hard-to-control and strobilurin-resistant diseases. Monitor field conditions for disease signs and apply on a 14- to 28-day interval as necessary.

2015 research trials by the University of Tennessee showed that applying Aproach® Prima to fields threatened by frogeye leaf spot infection increased yield by 52.6 bushels per acre over untreated plots.

Aproach® and Aproach® Prima fungicides are not available in all states. See your DuPont representative or retailer for availability.
