Due in large part to the continued wet weather, cotton diseases have been on the increase over the past two weeks. Boll rot, bacterial blight and target spot have all been observed throughout the MS cotton production system.
Bacterial Panicle Blight of Rice Observed in Multiple Delta Fields
Bacterial panicle blight has been a rare disease in MS rice production systems. Over the past several years, bacterial panicle blight has only been observed in years when high temperatures occurred for extended periods of time during flowering. The specific
Numerous Caterpillars Showing Up in Cotton
Over the last couple weeks, we have received numerous calls about multiple caterpillar pests in Bt cotton. By far, the most common and widespread species has been bollworm, but populations of fall armyworm are also high and we have even heard
Cotton Fruit Shedding – 3 Weeks of Pain
Cotton in many areas of the state has been shedding fruit for the past two to three weeks. Prior to the onset of this shed, many fields were retaining greater than 90% of the total fruiting forms. First and foremost,
Diamide Insecticides and Soybean Looper Management
Since the introduction of the diamide insecticides (Belt, Prevathon, Besiege), soybean loopers have essentially been a non-issue. We all have plenty of data showing 24-35 day residual control of soybean loopers, however, the long residuals are a blessing and curse
Insect Pheromone Trap Counts, August 10, 2016
Bollworm and tobacco budworm pheromone trap catches were overall similar to last week, and slightly above the long-term average trap catches for both pests at this time of year. This is the third consecutive week with strong numbers, so susceptible
Stink Bugs and Redbanded Stink Bugs in Soybeans- What to do?
Over the last few weeks we have been getting more and more calls about redbanded stink bug in soybeans. Redbanded stink bugs (RBSB) are voracious seed feeders, infest fields later, and are more difficult to control than greens, southern greens,
Managing Late Season Cotton Growth
A number of calls have came in this week regarding management of late season cotton growth. For the greater part of the growing season, fruit retention has been outstanding in the 2016 MS cotton crop. However, about two weeks ago
Bollworm and Budworm Pheromone Trap Catches, August 3, 2016
Trap catches for bollworm remained high in some areas this week. Several traps caught more than 200 moths, while one trap in Washington County had 568 moths this week. Overall, moth catches were somewhat lower than they were last week,
When Should I Start Corn Harvest and What are the Implications?
Corn harvest will be upon us soon and anticipation is building. However, we still need to get this corn crop out of the field and safely deliver it to market. Your ability to successfully harvest your crop may vary depending on several factors.
Soybean Root Disease Update: August 3, 2016
In addition to the current foliar disease situation, root diseases are becoming widely observed throughout the MS soybean production area. Two of the more commonly observed diseases over the past several weeks have been taproot decline (TRD) and root-knot nematode foliar symptoms as a result of galling. Scouting for the presence of root-knot nematodes at this point in the season will aid in decisions for next season’s crop.
Foliar Soybean Disease Update: July 30, 2016
Foliar diseases continue to be observed throughout the Mississippi soybean production system. Low levels of frogeye leaf spot, Septoria brown spot and target spot have been frequently observed following the rainfall of the past two weeks. The first soybean rust on soybean was observed on Friday in Rankin County, MS on a single leaf in a field of R4/R5 soybeans.
Tarnished Plant Bugs in 2016
What has happened with tarnished plant bug this year? That has been the million dollar question this year in cotton. Numerous consultants have told us that tarnished plant bug populations are lower than they have ever seen in their careers
Rice Leaf Blast Confirmed in Mississippi
Leaf blast has been observed in the MS rice crop for the better part of the last three weeks. In most cases, lesions were observed in areas of fields where the floodwater was less than four inches.
Fall Armyworms in Rice: 2016
It looks like 2016 is shaping up to be another big year for fall armyworm in rice. As a reminder, our threshold in rice at this point in the season is 5 per 10 sweeps or when significant damage occurs.
Armyworms and Bollworms Becoming Widespread in Mississippi Crops
Bollworm: We have had numerous reports of bollworm (soybean podworm corn earworm) moths being flushed and small larvae in cotton and soybeans over the last couple weeks. This past week seemed to be the turning point in soybean. Nearly anyone with
Pheromone Trap Counts and Assays, July 22, 2016
Pheromone trap catches for tobacco budworm this week were at higher levels than normally seen during this time of year in all areas of the state. Bollworms were back down some this week after being quite high in some regions
How to Determine when you can Terminate Corn Irrigation
As the corn crop nears maturity, knowing when you can safely terminate irrigation timing, while optimizing yield potential is likely the most important decision you will face. In order to make this call, you need to estimate when the crop will reach maturity and how much moisture is present in your soil. This article outlines the steps needed to help make this process accurate and reliable.
Soybean Disease Update: July 16, 2016
Save for the appearance of a few common foliar diseases, the soybean disease situation remains fairly quiet. Septoria brown spot appears to be the most commonly occurring foliar disease. Scout fields for the presence of nematodes as well as stem diseases now to aid in next season’s decisions.
Potassium Deficiency in Cotton
Cotton is blooming throughout Mississippi and a large portion of the crop is in good to excellent shape. In addition, fruit retention is very good in most cases. Once cotton begins to square and progresses into bloom, nutrient demands alter
