Scouting and Managing Wheat Stripe Rust Infection at Tillering Stages

Stripe rust was detected in wheat in Washington County, MS in the wheat variety trial plots. Wheat fields in MS should be scouted at this time for the presence of stripe rust. Fungicide applications with products in the triazole (DMI) class of fungicides will prevent spread of the disease and in some cases where the disease has occurred and been observed in a wheat field may protect yield. . . . → Read More: Scouting and Managing Wheat Stripe Rust Infection at Tillering Stages

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)

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?
