Corn Diseases to Watch for While Scouting Corn

🕔11:58, 25.May 2012

Scouting corn can be especially challenging. Looking for disease within the corn canopy can take a tremendous amount of time and should be done a little different depending on the particular crop stage encountered. Once an ear has set (post-tassel) focusing on the ear leaf and above is generally the best scouting method since protecting the ear leaf is important. I’ve included several descriptions and pertinenent information regarding some of the more commonly encountered diseases in our corn production system.

Thrips in Peanuts and Their Impact on Tomato Spotted Wilt Virus (TSWV)

🕔11:14, 4.May 2012

There have been a lot of questions recently about thrips control in peanuts. In general, thrips will not hurt peanut yields except in EXTREME situations. Peanut seedlings are relatively vigorous compared to most of the crops grown in Mississippi. Foliar insecticide applications, though rarely needed, should be based on plant injury rather than thrips numbers.

End of Season Cotton Management Decisions for Fields Infected with Bacterial Blight

🕔12:15, 6.Sep 2011

Since the middle of July, numerous fields have been confirmed to have cotton plants infected with the bacterium that causes bacterial blight. The majority of the cotton fields were contained within a few counties in the Delta (Bolivar, Coahoma, Leflore, Quitman, Sunflower, Tallahatchie, Washington), and a low number of exceptions outside of the Delta (Calhoun, Grenada, Monroe, Yalobusha). The organism that causes bacterial blight has the potential to overwinter on cotton stubble left standing in the field.

Corn Ear Molds: What Color are Your Ears?

🕔13:15, 23.Aug 2011

This is the time of the year when I tend to get a ton of telephone calls regarding the presence of rotten (moldy) corn ears. Over the past few weeks I’ve observed a range of symptoms on corn ears. In extreme cases the entire ear was covered with fungal growth and corn kernels were beginning to sprout but in the less severe cases only the tip was covered with fungus. Many fungi can inhabit a corn ear and in some cases the specific fungus present will depend on health of the corn plant, whether or not the ear has sustained any damage (insect or otherwise), how far the ear filled out, previous crop in the field, length of time in the field past physiological maturity, plant stress and duration of the stress during the season, and environmental conditions.
