Protect Soybeans From Resistant Frogeye Leaf Spot
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.
2013 research trials by the University of Tennessee showed that applying Aproach® Prima decreased frogeye leaf spot disease severity from 50 percent to 15 percent and increased yield.
Adding Worm Control to the Tank Mix
If scouting reveals corn earworm, soybean looper, beet armyworm or fall armyworm infestations, you can tank-mix Aproach® Prima with 14 to 20 fluid ounces of DuPont™ Prevathon® insect control powered by Rynaxypyr® for increased efficiency, fewer trips across the field to reduce soil compaction and additional yield protection.
Prevathon™ insect control and Aproach® fungicide are not available in all states.
