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

IMG_0710

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. . . . → Read More: Automatic Soybean Fungicide Applications: Timing, Product Choice, Rates in Product Combination

This year we have seen tremendous population growth and expansion of Kudzu bugs from previous years. We have treated some acres already that were at threshold and I am confident that there will be many more to come based on what we are seeing around the state including the Delta region. . . . → Read More: Kudzu Bugs Numerous in MS Soybeans This Year

To date, I am not aware of any applications going out yet but numbers within some fields are definitely increasing. So far I have had about 10 reports of findings from the Delta region ranging from Cleveland to south of Inverness. . . . → Read More: Sugarcane Aphids and Sorghum Midge: MS Grain Sorghum

Choose Fungicide Product for Soybean Fields Based on Variety Planted

Frogeye leaf spot has been a commonly observed disease in MS over the past several seasons.

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. . . . → Read More: Choose Fungicide Product for Soybean Fields Based on Variety Planted

Reminder: Scout Schools Start Next Week

Mississippi State University will be hosting 5 scout schools this year. We have transitioned over the years to make these trainings much more diverse than insect pest alone. This year we will be including insects, disease, fertility, weed identification, and herbicide systems. There will be numerous hands on displays of insects, weeds, nutrient deficiencies in all . . . → Read More: Reminder: Scout Schools Start Next Week

Mixed Bag of Early Season Caterpillar Defoliators in Soybean

Over the last couple of weeks I have had numerous calls about caterpillar pest in young soybeans. Most of these have been concerning beans that are still in the vegetative stages (V2-V5). The species that are being found are bollworm, yellowstriped armyworm, green cloverworm, granulated cutworm, alfalfa caterpillar, cabbage looper, garden webworm, and yellowstriped armyworm. . . . → Read More: Mixed Bag of Early Season Caterpillar Defoliators in Soybean
