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
Southwestern corn borer traps picking up in several areas in state.
Bollworm catches were steady to slightly higher this week compared to the previous week. Tobacco budworm catches remained relatively low, with more in Northeastern MS than in the Delta. As has been true every week this year, bollworm catches were
I know it is a little early in the year, and very little if any rice is heading at this time. However, it is not too early to start thinking about rice stink bugs.
Favorable weather conditions continue to help this crop progress. Major problems outside of drift have been few for most of the spring; however, a few different issues have come up this week. Dr. Jeff Gore was called to help address a
At this point of the season, we still have some acres of soybean yet to be planted. The majority of those acres will be double cropped soybean behind harvested wheat. Given the environmental conditions that we typically expect during this
Adult pheromone trap counts the last two weeks have been quite similar. In general both bollworm and tobacco budworm counts are slightly below our 5-year average, but higher than during 2012, so you should expect to see typical pressure in
Last week consultant Brian Boyd, found the first incidence of Kudzu bugs in soybeans in the state of Mississippi in Warren County. Numbers were low, but they were definitely present. Mississippi is now up to 10 counties with positive finds,
Corn earworm moth catches were up slightly this week from last week, continuing a trend of catches that are higher than last year, and more in line with average catches over the last 5 years. Tobacco budworm catches continue to
I have had 10-15 calls recently on green and southern green stink bugs in beans that are either vegetative or at R1-R2 stage with no pods. Numbers have ranged from 4-5 to 8-11 per 25 sweeps depending on the field. It is not uncommon to have a field or two on occasion to have threshold numbers of stink bugs before soybeans put on pods, but the number of fields this year being reported is certainly unusual.
Bollworm and tobacco budworm trap counts were somewhat lower this week compared to last week. Bollworm counts are higher than last year, but lower than the 5-year average counts. Tobacco budworm counts are among the lowest recorded during the last
