Metribuzin is an important herbicide for controlling numerous weed species in wheat. However, wheat varieties may differ in tolerance to metribuzin. This article shows our evaluations of wheat varieties included in the current MSU Wheat Variety Trials for metribuzin tolerance. This should help you better assess potential for wheat crop injury.
The 3rd annual joint MEA/MAPPAN/MWSS annual meeting will be held next week at the Bost Extension Building in Starkville, MS next week. The dates of the meeting are Monday and Tuesday October 21-22. We have a very informative and exciting
Since the last update several new counties have been added to the list in MS. Currently we 33 counties positive for Kudzu Bugs. Out of the 33 counties, 21 have positive finds in soybeans.
Virus-infected soybean material has been observed almost statewide this season. The high numbers of bean leaf beetles can be blamed for some of the observed viruses; however, bean leaf beetles are not the only insects that can vector soybean viruses between plants. This specific blog update presents information on the three most commonly encountered soybean viruses in the MS soybean production system.
This publication lists those wheat varieties which have demonstrated superior productivity in the MSU Wheat and Oat Variety Trials and summarizes their characteristics. This impartial information should help you better assess wheat varieties and pick those suited for your farm this season.
Soybean disease questions still consider to be raised throughout MS. Even though soybean rust has been detected in 45 counties to date it appears we will have another season where yield losses as a result of soybean rust will be extremely limited and may only have occurred in a handful of fields. When making plans for next year consider sampling for nematodes in light textured soil classes. In addition, planting a frogeye susceptible variety in several years in a continuous soybean system may increase the likelihood of frogeye causing substantial yield loss.
While weeds can create problems for harvest equipment, many producers see the benefit of a harvest aid in creating a more rapid and efficient harvest in the absence of weeds
The United States Department of Agriculture – Agriculture Marketing Service recently released their 2013 cotton varieties planted report. Based on their numbers, ST 5458 B2F, ST 5288 B2F, DP 0912 B2RF, and PHY 499 WRF were the four most popular
Over the last month we have had numerous questions about terminating stink bug applications in late season soybeans. Typically we manage stink bugs until near harvest but there are several things to consider before making an application to control stink bugs in beans beyond R6 growth stage.
A common question that I have received from numerous consultants over the last several days is as follows. Hey don’t hammer me, but what happens if we mistakenly burned our corn stubble after we spread fall mixed good fertilizer and
Numerous questions have come in over the past few weeks regarding proper grain storage. Maintaining moisture below 15% is extremely important to reduce the likelihood of fungal growth. However, not all fungi that develop on harvested grain are problematic and toxin production is not something that can occur overnight. Even though fungi such as Aspergillus flavus can produce a green fungal growth on harvested grain not all fungi that grow on grain can be considered to be A. flavus.
It has often been said that cotton defoliation is more art than science. This thought is further nurtured when harvest aids perform differently under seemingly similar conditions. As with any pesticide application, many factors come into play when determining harvest
Red crown rot has been identified in additional fields in east MS throughout the 2013 season. Prior to 2013 only two counties had been identified as having red crown rot. However, three additional counties have been added this season (Clay, Newton, Union). Red crown rot symptoms can be misdiagnosed as several other diseases, including sudden death syndrome (SDS).
Determining when to terminate irrigation in soybean can be difficult. When making this decision, the goal is to make sure that adequate soil moisture is available to ensure that the soybean seeds reach maximum size. Terminating irrigation too soon can
Foliar diseases of soybean continue to be observed throughout the MS soybean production system. Over the past week additional counties containing soybean rust have been observed throughout the state. Stay tuned to information on the Crop Situation Blog regarding additional counties with soybean rust infected plant material should management suggestions change.
Soybean looper has started to show up in soybean and a few applications have started in some fields. We have several good options to manage soybean looper and all of them should be considered. Belt has become the go to insecticide for looper control in a lot of situations over the last couple of years.
Now that early planted beans are drying down quickly and insect pressure is increasing on late planted soybeans in some areas, many are asking when it is safe to quit spraying insect pest in soybeans. For most pest in soybean
I have looked at several fields over the last couple weeks that should be considered safe from yield loss from insect pest. Keep in mind that termination rules for insects in cotton do not mean the crop is “bug proof” but
Bollworm moth trap counts were lower at nearly every location this week compared to last week, indicating that bollworms are primarily in the larval stages at this time. Tobacco budworm trap counts were also low, so if a field is clean, new infestations
Numerous questions over the past few weeks regarding how well certain fungicide chemistries are managing frogeye leaf spot. Attached please find preliminary rating data from Starkville and Stoneville on how well particular products are managing observable symptoms of frogeye leaf spot. Additional data to follow as we continue to rate plots.
Two upcoming peanut field days offer the latest research recommendations and a chance to see some research/demonstration plots. The first field day will be held in south Mississippi, at Lucedale, the other in north Mississippi, at Clarksdale. Lucedale The Lucedale
Terminating soybean irrigation too early can result in lower yield due to decreased seed size. At the same time, irrigating when the crop no longer needs water can be a waste of time and resources. On Friday, August 30, 2013
During the 2011 growing season Chris Main, Bob Hayes, Tom Barber, Dan Reynolds, and myself put together a defoliation guide to cover Tennessee, Arkansas, and Mississippi. The folks at LSU have a similar guide for cotton in that state that
The time of year has arrived that growers are getting the itch to terminate irrigation applications in cotton. In a normal year, cracked bolls are present at the present calender date; however, cracked bolls are currently the exception rather than
As is typical for this time of year, bollworm pheromone counts were higher this week, particularly in the Delta. These moths are presumably those that developed in corn ears, and will now be seeking out hosts for another generation, likely
