Tips for Managing Late-Planted Soybeans to Maximize Profit

July 27, 2017

With diseases becoming more apparent in soybean fields at this point of the season, it’s important to be thinking about the benefits of applying a fungicide before it’s too late.

Late-planted soybeans are more vulnerable to diseases like frogeye leaf spot (FELS), as they have a higher chance of being infected at earlier growth stages.

In a recent Syngenta Twitter poll, 67 percent of respondents agreed:

This poll shows respondents believe late-planted soybeans are at a risk from disease.

With heavy spring rains delaying planting in several regions earlier this year, we recommend growers apply Quadris Top® SBX fungicide, which contains difenoconazole for preventive and curative control of strobilurin-resistant and susceptible FELS. Quadris Top SBX also contains azoxystrobin, which delivers plant health benefits to promote root strength and pod fill.

In field trials with high disease pressure, Quadris Top SBX plots yielded up to 23 bushels per acre (bu/A) over untreated soybeans.

Providing several plant health benefits, Quadris Top SBX-treated soybeans yielded between 5.8 and 14 bu/A over untreated soybeans in plots with very low FELS pressure.

This image shows the higher-yield difference between soybeans treated with Quadris Top SBX and untreated.

Applying a fungicide containing multiple modes of action to soybeans that have been infected by FELS could make all of the difference in this year’s yield.
