Monday’s Crop Production and World Agricultural Supply and Demand Estimates reports from USDA reversed last month’s changes and increased the expected size of the U.S. crop. Total U.S. production is forecast at 16.4 million bales, up 140,000 from October. The national yield was raised
The 2014 Row Crop Short Course will be held at the Bost Extension Center on the campus of Mississippi State University on December 1-3, 2014. Attendance is free of charge if you pre-register. Pre-registration is available until November 26. Registration
Boll rot appeared to be a common occurrence in numerous cotton fields at the end of the 2014 season. However, not all boll rot can be attributed to bacterial blight, especially in situations where the disease was not observed prior to harvest. Secondary fungal infection can ultimately obscure the observable boll symptoms associated with bacterial blight. Keep this in mind when scouting fields at the end of the season as bacterial blight boll lesions can oftentimes be obscured by secondary fungal invaders.
On behalf of the Mississippi State University Extension Service, we would like to cordially invite you to attend the 2014 Row Crop Short Course to be held at the Bost Extension Center on the campus of Mississippi State University from
The USDA released their 2014 Cotton Varieties Planted Report on September 12, 2014. Stoneville 4946 GLB2 was the top planted variety in Mississippi this year followed by Phytogen 499 WRF and ST 5289 GLT. The entire report may be accessed
Defoliation season is upon us and as such, the 2014 Mid-South Defoliation Guide has been updated and is ready for use. Those who have worked with cotton fully understand the challenges associated with defoliation. Further compounding an already difficult task
We have had numerous calls over the last couple weeks about small, 2-5 day old larvae, under bloom tags in Bt cotton that is near, at, or beyond cutout. All of the research done to this point suggests that cotton is safe from bollworm damage when it reaches node above white flower 5 plus 300 heat units.
As we approach the end of August, terminating cotton irrigation is on the mind of many folks. In cotton, we recommend terminating furrow irrigation at first cracked boll. If you anticipate bolls opening in the immediate future and have been
Over the last 7 days we have had numerous reports of high bollworm numbers in some BollGard II, TwinLink, and WideStrike fields in the Mississippi Delta. We have seen fields in the past that reach treatable levels but some reports are much higher than we have seen in recent years. At this time there does not appear to be any specific varieties that are adversely affected more than others. It appears to be a function of high pressure in isolated areas at this time.
The last effective bloom date is the last date that a white flower will accumulate enough heat units to mature into a harvestable boll. Generally speaking it takes 850 heat units for a white flower to mature into a harvestable
This week we encountered another issue with a surge valve. After irrigating with a surge valve the producer noted that neither the 6” nor 12” sensors responded to the irrigation. When investigating the problem it appeared that the grower had
The evolution of cotton cultivars has led to higher yield potentials and shorter growing seasons compared to the historical full season cultivars favored in the Mid-South. These newer, faster fruiting cultivars may require more nutrients than older outdated cultivars. Recently,
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.
The North Mississippi Research and Extension Center’s Agronomic Row Crops Field Day on Thursday, August 7 will present the latest research to the area’s row-crop farmers and consultants. The field day will be from 8 a.m. to 1:30 p.m. at the Lee County Agri-Center Magnolia Conference Center on Highway 145 South in Verona.
Additional bacterial blight has been observed in the MS cotton production system. At present, 12 counties have been reported to contain infected cotton.
Several calls have come in this week regarding random yellow spots in cotton fields. While there are a multitude of things that may cause this, there seems to be an underlying theme in many cases. Everyone is aware of the
This past week we encountered the following situation. A Grower irrigated a silt loam field utilizing a surge valve. When he checked his moisture probes neither the 6” nor the 12” Watermark™ sensor had moved. What’s going on? After careful
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.
This past Monday (June 30), USDA released their annual Acreage report. The report is preceded by the March Prospective Plantings report with the difference being a more solid, confirmed acreage number in the acreage report compared to an expected, planned
Bollworm catches were similar to the previous week while tobacco budworm counts continue to slowly rise. Neither is particularly high for this time of year. Southwestern corn borer counts were up sharply this week, with a few traps in the
Tomorrow is July 4th which usually coincides with the arrival of blooms in cotton fields. Although the crop is somewhat later than “normal” this year, blooms are arriving daily. Monitoring nodes above white flower is a useful tool for determining
Mississippi State University and Monsanto Company will be conducting a field day in Robinsonville, MS on Thursday, July 10, 2014. The field day will focus on the Roundup Ready(R) Xtend Crop System in cotton and soybeans. Field demonstrations will include cotton and soybean germplasm
Tarnished plant bug numbers have actually started off at low to moderate levels this year in the Delta region but just in the last few days numbers seem to be picking up pretty good in a few locations and square
Mississippi State University and Dow AgroSciences will be conducting a field day at the farm of Douglas and Chris Hood on Wednesday, July 2, 2014. The field day will begin at 9 a.m. and will focus on Enlist(TM) Weed Control System in
Several folks throughout the state have began applying plant growth regulators to their cotton crop and many more will likely start over the next couple of weeks. Although plant growth regulators have gotten exponentially cheaper over the past 25 years,
