Southern Blight of Peanuts – It’s Arrived

Southern blight, has been found on peanuts in several areas of the state this week.

Southern blight is a plant disease that attacks the crown and below ground parts of peanuts. It causes the plant to wilt and die or reduces nut quality. The best management tool is a rotation with 3 years . . . → Read More: Southern Blight of Peanuts – It’s Arrived

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

Corn Disease Update: June 19, 2015

For the most part, the corn disease situation has been quiet. Limited occurrences of common rust and northern corn leaf blight have been observed in some Delta fields. With the cooler and wetter conditions encountered early in the season it is possible that some uncommon diseases could be encountered. . . . → Read More: Corn Disease Update: June 19, 2015

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

Peanut Growers: Tropical Storm Bill

Posted June 16, 2015. The low pressure in the Gulf has turned into tropical storm Bill. It is now predicted to impact the coast further south than it was several days ago. Updated forecasts by NOAA indicate that the primary rains generated by the storm will go north of Mississippi (http://www.nhc.noaa.gov/refresh/graphics_at2+shtml/090804.shtml?rainqpf#contents).

Identifying Corn Reproductive Growth Stages and Management Implications

Silk Stage

Corn reproductive stages generally comprise about 60 days for corn hybrids grown in Mississippi at normal planting dates. Identification of these stages is critical for making prudent management decisions and anticipating crop response to practices and environmental conditions. . . . → Read More: Identifying Corn Reproductive Growth Stages and Management Implications

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

What is Appropriate Timing for the “Tassel Shot” on Corn?

Aerial Application

More growers are implementing different “tassel shot” inputs as part of their corn management program. Wet weather and other issues may further complicate application timing of such inputs. This article discusses whether specific timing makes a big difference or not? . . . → Read More: What is Appropriate Timing for the “Tassel Shot” on Corn?
