Phytotoxicity as the result of applying fungicides that contain an active ingredient that produces an “injury” to soybean leaves has been observed this year. Large areas of fields or entire fields in an area with observable interveinal chlorosis should be observed for the presence of a specific disease. Observing root systems as well as cutting into the main stem to expose the vascular tissue should help tell the difference between many soybean root diseases and whether or not a disease is present.

Automatic Soybean Fungicide Applications: Timing, Product Choice, Rates in Product Combination

Automatic Soybean Fungicide Applications: Timing, Product Choice, Rates in Product Combination Updated

🕔11:42, 19.Jun 2015

Questions continue regarding fungicide products to be used at the R3/R4 application timing. The most important decisions should be made based on the specific variety planted in each field since frogeye leaf spot is resistant to the strobilurin class of fungicides meaning that stand-alone strobilurin products are no longer effective against the disease. See the information contained within this blog post regarding fungicide products, effective rates of products in pre-mix combinations and the effectiveness of some fungicides on managing frogeye leaf spot.

Choose Fungicide Product for Soybean Fields Based on Variety Planted Updated

🕔15:13, 31.May 2015

Choosing a foliar fungicide product for either a common fungicide application at a specific growth stage in the absence of foliar disease or in the presence of disease should be based on the soybean variety planted. Widespread fungicide resistance to the strobilurin fungicides in the MS soybean production system within the frogeye leaf spot fungal population may ultimately change how we use fungicides. Choose a fungicide product based on whether or not frogeye will occur in a susceptible variety rather than choosing a fungicide based on price.
