Maintaining clean and weed-free field roads around sweetpotatoes is thought to help minimize rodent injury and make access for crop scouting and monitoring more efficient. Roads are most often maintained weed-free with glyphosate applications. However, off-target movement of glyphosate onto
Foliar corn diseases continue to be observed throughout MS. Even though common rust, gray leaf spot, northern corn leaf blight, and southern corn leaf blight continue to be observed at low levels, additional diseases have been encountered over the past two weeks.
Numerous fungicide trials were conducted during the 2013 season to determine the effectiveness of some popular commercially available fungicides on managing frogeye leaf spot. Attached find data as related to some R5 and one R5.5 fungicide application on a frogeye leaf spot susceptible Maturity Group IV variety in Stoneville (4 trials) and Starkville (1 trial).
Populations of the white sugarcane aphid are expanding and increasing across the state. We have confirmed the presence of white sugarcane aphid in grain sorghum in 7 counties in Mississippi (Fig 1) and there are likely more. The counties where white sugarcane aphids have been found include Bolivar, Washington, Humphreys, Quitman, Panola, Tunica and Oktibbeha.
Several new fungicide products are commercially available for soybean productions systems this season. Affiance, Aproach, Aproach Prima, Cercobin, Equation, Fortix, Incognito (4.5F and 85WDG), Overrule, Topsin XTR, and Viathon all have labels for soybean production systems and may be marketed throughout MS for application to soybean plants. Rates, pre-harvest intervals, as well as the active ingredients and links to the full label are included.
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
It’s okay to let it down! Defining proper flooding of rice can be somewhat challenging depending who you talk to. One thing is for sure, to take advantage of the cost saving of straight levees and multiple inlet rice production,
By now most folks have heard of Kudzu bugs. In fact, we have now confirmed them in 52 counties in Mississippi. Kudzu bugs, Megacopta cribraria, was first found in Georgia in 2009. Since that time it has spread rapidly across the southeast kudzu bug map 7_8and is now moving west in to Mid-southern states. It was first found in Mississippi in 2012 and now covers most of the state.
With the recent passage of the 2014 Agricultural Act a number of new choices are available for producers, while many of the previous options are no longer available. The analysis here examines these choices for soybean production in Mississippi. The
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.
Considering the abundant rainfall during June and the corn crop progressing closer toward maturity, many are wondering whether additional irrigation may even be needed. This article discusses how to make that and other late-season irrigation decisions.
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
Sentinel plots were planted in the spring of 2014 to serve as a source of soybean plants for monitoring important, potentially yield-limiting soybean diseases throughout MS. The sentinel plot network has protected MS soybean farmers for 9 years now. With financial aid from the Mississippi Soybean Promotion Board and the United Soybean Board, the sentinel plots will be scouted for the remainder of the 2014 season.
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
The Mississippi Farm Bureau Federation Summer Peanut Commodity Meeting will be held Thursday, July 17, 2014 at the Monroe County Extension Office in Aberdeen. The building is located at 517 Highway 145 North in Suite 1. The purpose of this
Foliar corn diseases continue to be observed throughout the MS corn crop. Common rust, gray leaf spot, northern corn leaf blight, and southern corn leaf blight are all present at low levels throughout the Delta. As of Wednesday (June 25, 2014), southern corn rust had only been observed in southeastern MS (Forrest, George, Greene, Jackson, Perry, and Stone counties).
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
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.
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,
We are having lots of questions concerning the proper set up of surge valves. First, please consider some of the basic terminology associated with furrow irrigation. We encourage you to visit http://www.youtube.com/watch?v=46sSLFBUrh8 and view the video before continuing. Phases
In 2013 a new aphid pest called the White Sugarcane Aphid, Melanaphis sacchari, was detected in grain sorghum in 38 counties in Texas, Louisiana, Oklahoma, and one county in Mississippi. This species has apparently been around for years but the hosts switch to grain sorghum appears to be new. This pest can be devastating to grain sorghum if populations reach high densities. In fact, some fields have seen 100% yield loss. Another major factor is this aphid is difficult to control with currently labeled products.
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
