Bean leaf beetle numbers have been increasing steadily over the last couple weeks. We have actually made bean leaf beetle targeted sprays on a number of acres in recent days. Yield loss is caused by defoliation and less frequently by
Diseases of soybean continue to be observed throughout the MS production system. At present, soybean rust has not been detected within MS; however, we continue to scout for the presence of rust, as well as additional diseases of economic importance throughout sentinel plots as well as commercial soybean fields. Frogeye leaf spot, sudden death syndrome, stem canker, and aerial blight continue to be hot topics for most soybean farmers.
We are quickly approaching that time of year where some of the earlier planted fields are turning color and others are approaching R6 vey quickly. Often times many of the insect pest we deal with “pile in” about this time and growers face the tough decision to treat when it may not pay back or try and race them to the end. We have devoted a lot of time and effort in recent years to evaluate and validate thresholds in soybeans under the current growing practices in Mississippi. Through these research efforts we have made several changes to insect thresholds and termination points for insect pest of soybeans in MS.
Soybean diseases continue to be observed throughout MS. Brown spot, aerial web blight, frogeye leaf spot, Cercospora blight are the predominant foliar diseases observed at present. In addition, several root diseases are becoming apparent from fields across the state.
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 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.
“It ain’t over till it’s over!” Amazing as it seems, several producers have not laid poly pipe. After the five plus inches of rainfall we received last week, some producers are questioning the need to lay pipe this late in
Foliar diseases of soybean continue to be observed throughout the state. At present, no soybean rust has been detected in Mississippi. However, aerial web blight, downy mildew, frogeye leaf spot, and target spot have all been observed in light to severe situations depending on field location.
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).
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
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
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.
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
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
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
The importance of soil moisture sensors is becoming more evident as we continue forward this growing season. Today (Monday, June 16th), we received a call regarding sensor readings that were assessed early this morning. The following are the data discussed in this scenario.
Frogeye leaf spot management continues to be a hot topic during the 2014 season. Scattered reports of frogeye in R3+ soybean fields continue to be made. Most of the questions at this time tend to be regarding fungicide management suggestions at the R3/R4 application timing. Knowing what varieties are planted in fields is one of the most important determining factors since susceptible varieties should be managed differently at R3/R4 than frogeye tolerant varieties.
Although we have received lots of rainfall this season, it is time to initiate irrigation in soybean. Keep in mind that irrigation during the early vegetative phase provides little to no yield benefit. The reason to apply irrigation during the
Row crop irrigation needs are ramping up and one of the tools we can use to better assess soil moisture is Watermark sensors. This article describes how to analyze the data generated by sensors to help you better schedule irrigation.
With most of Mississippi receiving large amounts of rain during early June, opportunities for herbicide applications in soybean have been rare up to this week. Several calls have come in regarding herbicide options in situations where the weather has prevented
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
