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
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
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
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!
With water being one of the most expensive inputs of the rice producer, utilizing methods to limit the amount of water used makes economic sense.
Adoption of multiple inlet irrigation has allowed producers to reduce water consumption. Water use with multiple inlet has translated into an 18% (fig.2) reduction in water cost over straight levee . . . → Read More: Economic Benefits of Properly Managing Multiple Inlet Rice Irrigation
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
According to the USDA National Agricultural Statistics Service in Mississippi, 89% of the soybean acreage is planted as of the week ending June 8, 2014. At this time, 82% of the crop is emerged. The remaining acres to be planted will mostly consist of double-crop soybean behind wheat. At this time, Mississippiâ€™s soybean crop ranges from . . . → Read More: Soybean Crop Update and Replant Decisions
A corn, cotton, peanut, and soybean field day is scheduled for June 17th at the Delta Research and Extension Center in Stoneville, MS. The general theme of the field day will include pertinent information for mid-season row crop issues. . . . → Read More: Delta Research and Extension Center’s Agronomic Crops Field Day, June 17, 2014
Similar to most years when we have armyworms in wheat, there is the threat of having armyworms in seedling rice. We know of at least one rice field in Mississippi that was sprayed earlier this week. In general, damage from armyworms will not impact rice yields at this time of year unless they are beginning to reduce plant stand. This is especially true in hybrid rice planted at low seeding rates. . . . → Read More: Armyworms in Rice
Maintaining nitrogen applied as a pre-flood application is an important topic for rice farmers. Nitrogen can be lost by at least three different methods, two of which are considered to be bad since the N will become unavailable for plant uptake. . . . → Read More: Protecting Your Preflood Nitrogen
