2014 Delta Area Rice Meeting

ShallowFlood

The 2014 Delta area/Bolivar Co. Rice Meeting will be held at the Bolivar Co. Extension office on December 4, 2014. Mississippi rice producers, industry professionals, and other interested parties are invited to listen to presentations from MSU research and Extension faculty on a wide range of topics.  The Meeting will begin at 10:00 AM and conclude . . . → Read More: 2014 Delta Area Rice Meeting

Foliar Soybean Disease Update: September 3, 2014

Severe Cercospora blight (late-season Cercospora).

Foliar diseases of soybean continue to be observed throughout the MS soybean production area. At present, no soybean rust has been detected in MS; however, Cercospora blight and frogeye leaf spot as well as several pod diseases (topic of the next blog post) are being observed in numerous soybean fields. . . . → Read More: Foliar Soybean Disease Update: September 3, 2014

Fungicide Phytotoxicity: Check the Fungicide Applied Prior to Blaming SDS

Severe phytotoxicity associated with a foliar fungicide application.

Phytotoxicity, associated with the application of some specific foliar fungicide products, has been observed in numerous commercial soybean fields again this season. Keep in mind that the symptoms associated with fungicide phytotoxicity will appear quite similar to sudden death syndrome (SDS). However, SDS only occurs in light soil classes. When scouting fields, keep in mind that an entire field with SDS-like symptoms might be the result of fungicide phytotoxicity, thus not a disease after all. . . . → Read More: Fungicide Phytotoxicity: Check the Fungicide Applied Prior to Blaming SDS

Soybean Disease Update: August 16, 2014 (UPDATED)

Severe frogeye leaf spot.

Diseases of soybean continue to be observed throughout the MS production system. At present, soybean rust has not been detected within MS; however, we continue to scout for the presence of rust, as well as additional diseases of economic importance throughout sentinel plots as well as commercial soybean fields. Frogeye leaf spot, sudden death syndrome, stem canker, and aerial blight continue to be hot topics for most soybean farmers. . . . → Read More: Soybean Disease Update: August 16, 2014 (UPDATED)

Soybean Disease Update: August 1, 2014

Brick red fungal structures (perithecia) associated with red crown rot.

Soybean diseases continue to be observed throughout MS. Brown spot, aerial web blight, frogeye leaf spot, Cercospora blight are the predominant foliar diseases observed at present. In addition, several root diseases are becoming apparent from fields across the state. . . . → Read More: Soybean Disease Update: August 1, 2014

What Should You do about Late Southern Corn Rust?

Southern rust of corn.

Southern corn rust continues to be observed throughout MS. We continue to receive calls regarding late fungicide applications (> R4/R5) to reduce yield losses attributed to southern rust. Numerous myths regarding the disease have been widely spread throughout the MS corn production area including death of a corn plant in as fast as 7 days following southern rust infection and lodging as a result of heavy southern rust infection. . . . → Read More: What Should You do about Late Southern Corn Rust?

North Mississippi Research and Extension Center’s Agronomic Row Crops Field Day on Thursday, August 7

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
