Rice Leaf Blast Confirmed in Mississippi

Typical symptomology of rice leaf blast

Typical symptomology of rice leaf blast

Last week’s weather pattern in the Delta provided near perfect conditions for rice blast (Pyricularia grisea) to occur.  Rice blast is generally categorized by the plant part infected (e.g., leaf, neck, panicle).  Blast favors mild humid weather, frequent rainfall, and extended periods of leaf wetness.  On susceptible cultivars, yield loss . . . → Read More: Rice Leaf Blast Confirmed in Mississippi

Checking peanuts? Take your shovel! Unlikely southern blight* expression found in south Delta.

Yesterday we found our first southern blight* damage to peanuts for 2014. The timing is not unusual, we generally start finding the disease when the crop canopy closes. What is unusual is where on the plants the disease was found.

Jason and I were in a large field of peanuts between Tchula and Greenwood. An occasional plant . . . → Read More: Checking peanuts? Take your shovel! Unlikely southern blight* expression found in south Delta.

Foliar Soybean Disease Update: July 20, 2014

Target spot of soybean.  Note the yellow halo around lesions typified by concentric rings.

Foliar diseases of soybean continue to be observed throughout the state. At present, no soybean rust has been detected in Mississippi. However, aerial web blight, downy mildew, frogeye leaf spot, and target spot have all been observed in light to severe situations depending on field location. . . . → Read More: Foliar Soybean Disease Update: July 20, 2014

Corn Disease Update: July 14, 2014

Foliar corn diseases continue to be observed throughout MS. Even though common rust, gray leaf spot, northern corn leaf blight, and southern corn leaf blight continue to be observed at low levels, additional diseases have been encountered over the past two weeks. . . . → Read More: Corn Disease Update: July 14, 2014

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

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
