With heavy spring rains, many growers had no choice but to plant their soybeans late this season.

The Ohio State University research shows later planted soybeans have a higher chance of being infected earlier in the season with frogeye leaf spot (FELS) and could experience yield losses of 5 bushels per acre (bu/A) if infected before the R3 growth stage.

Late planted soybeans have an increased risk of damage from FELS, and especially strobilurin-resistant FELS – a disease that has been confirmed in recent years in 11 different states across the South and Midwest.

Strobilurin-resistant FELS is often difficult to control. Syngenta advises growers to treat for strobilurin-resistant FELS proactively with multiple modes of action, particularly in fields that have had confirmations of this disease in the past.

Syngenta offers Quadris Top^® SBX fungicide, which contains difenoconazole for preventive and curative disease control and azoxystrobin for crop enhancement benefits, promoting root strength and pod fill.
