Rice Stink Bugs in Mississippi Rice

As more and more of the rice crop starts to head, it is time to start thinking about rice stink bug. We have been sweeping some grass around the Delta for the last few weeks, and the one general comment I will make is that populations have been fairly low in most areas. We have seen fairly high numbers in a couple places, but it was small patches of heading grass in isolated locations. . . . → Read More: Rice Stink Bugs in Mississippi Rice

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

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

Cotton Bacterial Blight Update: July 18, 2014 (UPDATED 7/28/2014)

Additional bacterial blight has been observed in the MS cotton production system. At present, 12 counties have been reported to contain infected cotton. . . . → Read More: Cotton Bacterial Blight Update: July 18, 2014 (UPDATED 7/28/2014)

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

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
