Managing Frogeye Leaf Spot with Fungicides: 2013 MS Trial Data

DSC_0909

Numerous fungicide trials were conducted during the 2013 season to determine the effectiveness of some popular commercially available fungicides on managing frogeye leaf spot. Attached find data as related to some R5 and one R5.5 fungicide application on a frogeye leaf spot susceptible Maturity Group IV variety in Stoneville (4 trials) and Starkville (1 trial). . . . → Read More: Managing Frogeye Leaf Spot with Fungicides: 2013 MS Trial Data

Additional Fungicide Products Available for Soybean Production Systems – UPDATED 7/12/2014

Several new fungicide products are commercially available for soybean productions systems this season. Affiance, Aproach, Aproach Prima, Overrule, Topsin XTR, and Viathon all have labels for soybean production systems and may be marketed throughout MS for application to soybean plants. Rates, pre-harvest intervals, as well as the active ingredients and links to the full label are included. . . . → Read More: Additional Fungicide Products Available for Soybean Production Systems – UPDATED 7/12/2014

Scouting Cotton for Bacterial Blight in 2014

Bacterial blight of cotton can produce several different symptoms on plant parts.  Leaves, bracts and petioles all can exhibit symptoms of the disease.

Once again, bacterial blight has been observed in the MS cotton crop. At present, several fields in the south and north Delta as well as a single field in east MS have been observed to contain bacterial blight infected cotton leaves. To date (July 8, 2014), a single cotton variety has been reported to be infected in all fields. . . . → Read More: Scouting Cotton for Bacterial Blight in 2014

The 2014 Mississippi Soybean Disease Monitoring Network

Sentinel plots were planted in the spring of 2014 to serve as a source of soybean plants for monitoring important, potentially yield-limiting soybean diseases throughout MS. The sentinel plot network has protected MS soybean farmers for 9 years now. With financial aid from the Mississippi Soybean Promotion Board and the United Soybean Board, the sentinel plots will be scouted for the remainder of the 2014 season. . . . → Read More: The 2014 Mississippi Soybean Disease Monitoring Network

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

Corn Disease Update: June 28, 2014

Mature gray leaf spot lesion.  Note the parallel lesions and the absence of the lesion crossing the veins.

Foliar corn diseases continue to be observed throughout the MS corn crop. Common rust, gray leaf spot, northern corn leaf blight, and southern corn leaf blight are all present at low levels throughout the Delta. As of Wednesday (June 25, 2014), southern corn rust had only been observed in southeastern MS (Forrest, George, Greene, Jackson, Perry, and Stone counties). . . . → Read More: Corn Disease Update: June 28, 2014

Frogeye Leaf Spot Management Suggestions for the 2014 Season

Frogeye leaf spot management continues to be a hot topic during the 2014 season. Scattered reports of frogeye in R3+ soybean fields continue to be made. Most of the questions at this time tend to be regarding fungicide management suggestions at the R3/R4 application timing. Knowing what varieties are planted in fields is one of the most important determining factors since susceptible varieties should be managed differently at R3/R4 than frogeye tolerant varieties. . . . → Read More: Frogeye Leaf Spot Management Suggestions for the 2014 Season

Corn disease update June 13, 2014

To date this has been a fairly light corn disease year. However, some lesser observed diseases, such as anthracnose leaf blight can be observed on the lowest leaves in some corn fields. Common rust, northern corn leaf blight, and to a much lesser extent southern corn leaf blight can also be observed in some corn fields. . . . → Read More: Corn disease update June 13, 2014

The Tassel Shot: When is the Best Time?

Aerial Application
