Fungicide Application and Management

The use of fungicides often makes economic sense when there is enough disease to cause significant yield reductions. However, fungicide applications do not always provide an economic yield benefit when disease pressure is low. Scouting and deciding which fields have significant disease risk can help a farmer make fungicide applications in fields most likely to benefit.  Tom Allen, Mississippi State University Extension plant pathologist, suggests that applying fungicide at the R3/R4 growth stage results in a positive yield benefit the majority of the time. Mississippi Soybean Promotion Board recently mailed information on fungicide application and timing, click here to view the document.
