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.
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
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
Bean leaf beetle numbers have been much higher than they have been in the last couple years. We have actually made bean leaf beetle targeted sprays on a number of acres this year. Yield loss is caused by defoliation and
Trap counts were generally steady to slightly lower this week compared to last week for both bollworm and tobacco budworm. As has been the case all year, counts are higher than in 2012 but slightly lower than long-term average catches.
Seems like we are adding new counties every week. We are now at 24 counties total with 16 of those having kudzu bugs found in soybeans. At this time we have actually treated a field or two for kudzu bugs in
For the second week in a row, tobacco budworm counts are higher than average for this time of year. Bollworm catches were fairly typical for this time of year, so in non-Bt crops where both pests develop (like soybean), a
This week we added four new counties for positive finds of kudzu bug. All finds were in soybeans. This weeks new counties were Benton, Noxubee, Lawrence, and Issaquena.
Several insect pests have started to show up in cotton over the last couple of weeks. In most cases in the Delta, applications have shifted from targeting plant bugs to targeting plant bugs plus at least one other pest. In most of those situations, tank mixes with multiple insecticides are needed to control the whole complex. In this update, we will attempt to cover all of the current pests and highlight some control options.
With the exception of the last three years, stink bugs have always Mississippi’s number one insect pest of soybean. There are many species of stink bugs in MS soybeans but the three predominate species are Southern Green, Green, and Brown
Trap counts for tobacco budworm were sharply higher this week in the MS Delta for the first time this year. Bollworm counts were also somewhat higher in the Delta compared to last week. However, from a historical perspective bollworm counts
As expected based on field observations, trap counts for bollworm were higher this week. They are not higher than historical averages, but are definitely high enough to cause economic infestations in some fields. Tobacco budworm pressure exists, but remains low, so most Heliothines
With many consultants reporting flushing high numbers of moths over the last 7-10 days, bollworm larvae are beginning to turn up at treatable levels in some fields now. Over the last couple days I am hearing reports of treatments going out
Usually in Mississippi the major bollworm flight coming off of corn usually ranges from June 25-July 7th on average. We started getting our first calls out of the south Delta this week. Many consultants are reporting scattered worms and eggs
Bollworm and tobacco budworm counts are lower in the Delta region this week compared to last week, while this week’s trap catches in northeastern MS are similar to last week. As can be seen in the table, catches of both species
I have had numerous calls on kudzu bugs in the last couple weeks, mainly from the southwest part of the state. Kudzu bugs were found in 4 counties in 2012 in MS. In 2013 we have now confirmed 10 additional counties, in which 6 were found in soybeans. Since these initial finds in soybeans in Warren, Claiborne, Hinds, Yazoo, Stone, and Rankin Counties, it has become common for consultants to find 4-8 adults per 25 sweeps, in a few cases up to 10-15 in a couple of these areas.
Bollworm trap counts continue at levels similar to or slightly higher than the past several weeks. However tobacco budworm counts are sharply higher during the last two weeks in certain traps. This would suggest that any worm populations found in soybeans
The Soybean Minute is a new radio program that can be heard on the Mississippi AgriNews Network. These reports, sponsored by the Mississippi Soybean Promotion Board and the United Soybean Board, offer the latest information on soybean production in Mississippi.
Mississippi traditionally does not plant a lot of grain sorghum compared to some states but the acres we plant (42K according to USDA, 2013) have to be scouted and managed for insect pest at least weekly. Grain sorghum in Mississippi can have significant insect issues in some years, especially on late plantings.
With the dry weather we have had recently, spider mites are starting to show up in a lot of cotton fields. Spider mites can be one of the most difficult pests to manage in cotton for several reasons.
Many of the soybeans are now reaching R3-R4 growth stage so fungicides are commonly being applied. I have received quite a few calls questioning whether or not to add an insecticide in the tank since a trip was being made
In the last 7 days we have received a number of calls about adult plant bugs beginning to move into squaring cotton. In many cases, fields that were treated last week have higher or equal numbers this week. As we
