There are questions every year about spraying thrips in peanut. In general, we have recommended using an at-planting insecticide to manage thrips and that is adequate in most situations. However, we did a study two years ago where we sprayed peanuts
In March, the Mississippi Bureau of Plant Industries and other states in the Mid-South submitted Emergency Exemption (Section 18) requests to use Transform for tarnished plant bug control in cotton. The reason for this request is that the original registration
Every year we have a point in the planting season where we start getting questions about how heavy rainfall and cool temperatures affect seed treatments in rice. The one thing to remember is that the clock starts ticking on the
We have had several calls over the last week about cutworms reducing plant densities in cotton, soybean, and non-Bt corn. Based on the number of calls, it appears that cutworm populations are much higher than they have been the last several
Mississippi State University will be hosting 5 scout schools this year. We have transitioned over the years to make these trainings much more diverse than insect pest alone. This year we will be including insects, disease, fertility, and herbicide symptomology.
Although commodity prices have not been exciting for any crop we grow, Mississippi is expected to see cotton acres increase as much as 40% this year. As we have been traveling the meeting circuit, the common denominator has been, “What inputs can we cut in an off year?” This has been asked of all crops lately, not just cotton. It seems that seed treatments are the first thing that comes up during this conversation in every crop; however, this is not a viable option in cotton.
We posted an article last spring about utilizing several best management practices in an overall IPM program to manage tarnished plant bug in cotton. We included a pdf that highlights all of the research we have conducted over the last
The 2016 Insect Control Guide for Agronomic Crops is now available online. Hard copies will be available in January. Notable changes this year include the removal of pyrethroid insecticides for bollworm control in all crops due to resistance and poor
By now many of you may have heard that Sulfoxaflor, the active ingredient in Transform, recently lost a major court decision in the Ninth Circuit Court of Appeals. The suit was led by the Pollinator Stewardship Council, beekeepers, and other bee
The 2015 Delta area/Bolivar Co. Rice Meeting will be held at the Bolivar Co. Extension office on November 5, 2015. Mississippi rice producers, industry professionals, and other interested parties are invited to listen to presentations from MSU research and Extension
Some grain sorghum still remains to be harvested around the state and sugarcane aphid populations have remained high in a lot of areas. We had a post by Erick Larson and Angus Catchot a couple of weeks ago here about use of harvest
We have had numerous calls over the last 2 weeks about caterpillars in peanut from all around the state. In every case, the calls have involved a complex of multiple species including bollworm/tobacco budworm, cutworms, armyworms, saltmarsh caterpillar, loopers, and rednecked peanut worm.
In 2014 we saw two brief time periods of less than satisfactory control with Transform on sugarcane aphids in grain sorghum across a broad geography. At the time we were mixing a lot of pyrethroids with Transform, so initial thoughts were that
An agronomic crops field day will be held at Stovall farms, west and north of Clarksdale on Oakhurst Stovall Road. The field day will be held at Mr. Pete Hunter’s farm shop beginning at 10 am. MSU Extension Specialists will be present to discuss topics in corn, cotton, grain sorghum, peanut, rice and soybean.
There has always been a struggle with properly defining the correct cutoff for spider mites in cotton in the Mid-South region. For years we always loosely considered Node Above White Flower 5 (NAWF5 = Cutout) and 650 heat units the
There have been numerous calls and questions about Dectes Stem Borer over the last few years. It seems that numbers are increasing each year. This is not surprising when you consider the biology of the insect coupled with an increase in soybean acres in MS.
We have been getting calls on loopers showing up in soybean for about 2 weeks. In recent days there have been reports of defoliation exceeding 20% or numbers exceeding threshold in some areas in the central to southern part of the state. The bulk of our soybean loopers typically show mid to late August or even into September so this is a little early but certainly not unusual. Soybean loopers are migratory and work their way north each year from southern latitudes. Early arrival could be due to a number of reasons.
Over the last week we have been getting a lot of calls about extremely high bean leaf beetle numbers. Most calls have come from the Northwest Delta region of the state. 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 pod feeding
There have been numerous reports lately of high numbers of corn earworm and sorghum webworm in grain sorghum. I have heard some reports of numbers as high as 10X threshold. It is critical to scout and treat as needed to control these pest. There are three species that make up the headworm complex in grain sorghum; the corn earworm (bollworm), fall armyworm, and the sorghum webworm.
The MSU-DREC Rice Producer Field Day will be held in conjunction with the annual Mississippi Farm Bureau Federation Summer Rice Grower Meeting this year on the afternoon of July 30 at the Capps Center in Stoneville.. The Farm Bureau meeting
Week 5 Scouting Report Graduate Student Nick Bateman is running a weekly insect scout line in soybeans for part of his PhD project. We will be reporting his numbers weekly on the blog. Only insect pest that are being found in
Pheromone trap counts for bollworm were stable this week in the Delta while rising in the Northeastern region of Mississippi. Based on several weeks of fairly high bollworm moth catches, protection is likely needed in many fields against bollworm throughout the
When it comes to scouting for sorghum midge I have found that very few people have the confidence to accurately find them. Most believe if they are not finding them that they must be missing them or doing something wrong. The
After rising for several weeks, bollworm pheromone trap counts decreased some in the southern Delta region while slightly increasing in the hills and North Delta regions this week. This likely indicates that we are at peak moth flight for this
In just the last 3-5 there have been several reports of bollworms now showing up at threshold numbers in soybeans in the Delta region of the state. In many other areas of the Delta folks are reporting flushing extremely high
