2014 Soybean Variety Trial Disease Ratings, Part II: Maturity Group IV Varieties

IMG_0589

Disease severity was rated for each of the OVT soybean entries at all locations planted during 2014. Varieties were rated using a 0-9 scale where 0=no disease and 9=severe disease symptoms. The attachments on this blog post contain the Maturity Group IV and early and late entries. The MG V entries will be along shortly. . . . → Read More: 2014 Soybean Variety Trial Disease Ratings, Part II: Maturity Group IV Varieties

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

Not all Boll Rots are caused by Bacterial Blight

Boll rot as a result of Fusarium (as indicated by the pink growth of fungal structures on the boll).

Boll rot appeared to be a common occurrence in numerous cotton fields at the end of the 2014 season. However, not all boll rot can be attributed to bacterial blight, especially in situations where the disease was not observed prior to harvest. Secondary fungal infection can ultimately obscure the observable boll symptoms associated with bacterial blight. Keep this in mind when scouting fields at the end of the season as bacterial blight boll lesions can oftentimes be obscured by secondary fungal invaders. . . . → Read More: Not all Boll Rots are caused by Bacterial Blight

2014 North MS Research and Extension Center Soybean Disease Ratings UPDATED 11/17/2014

Variety trials were rated at the NMREC to determine the sensitivity of MG IV and V soybean varieties to frogeye leaf spot as well as Cercospora blight. Varieties were using a 0-9 scale where 0=no disease and 9=severe disease symptoms. Yield data will be available in a few weeks as this post only contains the analyzed rating values for the varieties contained in the trial at Verona. . . . → Read More: 2014 North MS Research and Extension Center Soybean Disease Ratings UPDATED 11/17/2014

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?
