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?

White Sugarcane Aphid Update – 8/1/2014

White sugarcane aphid infestations are increasing across the state and more applications are going out to manage this pest. Over the last week to 10 days we have heard about numerous fields that have received a second application. Remember, that the Section 18 label for Transform states that no more than 2 applications can be made in a field. . . . → Read More: White Sugarcane Aphid Update – 8/1/2014

Managing Cotton Aphids in 2014

We had a few calls over the last week about poor control of cotton aphid with Transform. In all of those cases, the field was actually sprayed for plant bugs with a 1.5 oz rate of Transform. That rate should be very effective on cotton aphid based on previous experience. As a result, we collected aphids from three different fields this week to test their susceptibility to Transform. . . . → Read More: Managing Cotton Aphids in 2014

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

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

Armyworms in Rice, Again!

It appears that 2014 is going to be the year of the armyworm in rice. I have had numerous calls, texts, and Tweets about armyworms in rice over the last week. If you have not had them in your rice to this point, consider yourself very lucky. . . . → Read More: Armyworms in Rice, Again!

Diagnosing Nutrient Deficiencies in Mississippi Soybeans

Soybean K 3

Diagnosing nutrient deficiencies is not rocket science, but can be cumbersome.  Many nutrient related issues occur early in season and can sometimes mimic herbicide injury in appearance.  In many instances it is difficult to tell the two apart. Most often nutrition related issues can be confirmed with a properly taken tissue test and corrected with an . . . → Read More: Diagnosing Nutrient Deficiencies in Mississippi Soybeans

Corn disease update June 13, 2014

To date this has been a fairly light corn disease year. However, some lesser observed diseases, such as anthracnose leaf blight can be observed on the lowest leaves in some corn fields. Common rust, northern corn leaf blight, and to a much lesser extent southern corn leaf blight can also be observed in some corn fields. . . . → Read More: Corn disease update June 13, 2014

Bollworms Plentiful in Young Soybeans

The soybean crop ranges from still in the bag to around V5 stage on average across Mississippi. Over the last 10 days I have received numerous calls (mostly from Delta region) about bollworms attacking vegetative stage soybeans. Arkansas has also reported high numbers of bollworms in soybeans. In fact, AR has some fields where bollworms are infesting emerging soybeans in the crook stage and eating them to the ground where vegetation was present during planting. . . . → Read More: Bollworms Plentiful in Young Soybeans

Video – How to Identify Corn Vegetative Growth Stages

V6 growth stage corn is beginning rapid growth and leaves little margin for error for postemergence herbicide application.

This is a video showing the methods used to determine the vegetative growth stages of corn or sorghum in the field. Further information can be found in the accompanying Mississipp Crop Situation blog article. . . . → Read More: Video – How to Identify Corn Vegetative Growth Stages
