Mid-Season Rice Update

IMG_0599

I would like to call this a midseason rice update, but in actuality we have rice in Mississippi ranging from one leaf to late boot in places, but most of the rice crop should be at or reaching mid-season.  Similar to 2014, our planting progress was spread out from a typical year.  Most of the central . . . → Read More: Mid-Season Rice Update

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

Crazy Top Downy Mildew of Grain Sorghum Observed in Many Delta Fields

Grain sorghum with a twisted top and a zinc deficient appearance may be suffering from crazy top downy mildew instead.

Crazy top downy mildew has been observed in numerous grain sorghum fields over the past two weeks. The general symptoms associated with the disease can oftentimes be confused for herbicide injury as well as a nutrient deficiency. Fields with grain sorghum that may have stood in water for an extended period of time may have become infected by the soilborne fungus. . . . → Read More: Crazy Top Downy Mildew of Grain Sorghum Observed in Many Delta Fields

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

Soybean “Mystery Disease” Update

Typical symptoms associated with the "mystery disease" in the lower plant canopy on soybean plants in the late vegetative or early reproductive stages.

Over the past several years a root disease of soybean has been observed throughout MS as well as adjacent states. Presently, research is being conducted to determine the causal organism(s) involved in the disease. On Wednesday (May 27), plants in several fields were observed throughout the Inverness as well as Leflore County (Quito) area. The fields have historically had an issue with this particular root disease. Some of the general symptoms and signs of the disease and a general update regarding research project are included in this particular post. . . . → Read More: Soybean “Mystery Disease” Update

For the most part the Mississippi wheat crop is clean with regards to foliar diseases. However, some important issues are occurring that need to be addressed with regards to Fusarium head blight, stem maggot feeding, and general herbicide injury as these three issues can easily be confused with one another at the field level. . . . → Read More: Wheat Disease Update: April 24, 2015
