Over the past week we have been getting a significant amount of rain across most of Mississippi. Unfortunately, most insects don’t mind the rain. Other than spider mites and aphids, we will likely have to continue managing insects in all crops despite the rain.
Over the last couple of weeks I have actually gotten quite a few questions about whether or not abamectin alone has any activity on plant bugs. Plant bugs have been light this year to date and spider mites have been
Overall, tarnished plant bug numbers appear to be decreasing across the Delta. Several things are contributing to this decline. The biggest factor is that the hot, dry weather is starting to take it’s toll on a lot of the wild

We have gotten multiple calls over the last week about fall armyworms in soybeans and peanuts. In every case, it has been a situation where people got behind on grass control when we were getting a lot of rain a couple weeks ago. In those situations, they have sprayed the grass during the last two weeks with products such as Select or Roundup that are relatively slow acting. A lot of the grass is infested with grass-strain fall armyworm and big worms start moving over into the crop about a week to ten days after the application when the grass starts to die.
This week has been the turning point on plant bugs and appears to be the week for the mass movement of migrating adults into cotton fields in many areas. Compared to previous years we are 10-14 days behind schedule. There have been quite a few sprays going out for tarnished plant bug this year but as a whole numbers have actually not been as high to date as many of us would have thought with the warm winter.
Three years ago if someone would have told me I would be blogging, I would have said they was crazy. When we started the Mississippi Crop Situation Blog, I had to look up the definition because I did not even
I have been getting quite a few calls about whether or not to mix an insecticide with the fungicide at the R3 growth stage of soybeans this year. The reason I am getting the calls is for the most part
The biennial North Mississippi Research and Extension Center Agronomic Row Crops Field Day will be held at the Lee County Agri-Center, Magnolia Conference Center, Highway 145 South of Verona, on Thursday, August 9, 2012, from 8:00 a.m. to 1:30 p.m.
Plant bug sprays are going out this week but overall numbers have not been as high as expected to date. This can change rapidly as plant bugs begin to move into fields from wild host plants. Click to Enlarge
Transform, a new insecticide containing the active ingredient sulfoxaflor, has received an emergency use exemption for Delta counties in Mississippi for the control of tarnished plant bug in cotton. This product represents a new mode of action and has excellent
Plant bug numbers are picking up this week in the Delta areas in the ditch banks. Click to enlarge
Plant bugs are still the predominant pest we are finding on wild hosts at this time. Click on to Enlarge
From time to time we send crews out to survey insect pest populations in ditchbanks adjacent to agricultural fields. This gives us an idea of what to expect later in the season based on what and how many pests we
Over the last couple of weeks I have had numerous calls about caterpillar pest in young soybeans. Most of these have been concerning beans that are still in the vegetative stages (V2-V5). The species that are being found are bollworm, yellowstriped armyworm, green
The insect scout schools for 2012 have been set. At each scout school we will go over biology, thresholds, and scouting techniques for each of the major pests of cotton, soybean, and corn. This is a great refresher for the
In most years it is not uncommon to overspray 20-30% of the cotton acres for thrips in MS. Last year (2011) was an anomaly in that we treated around 70% of the cotton acres for thrips due to extremely high pressure. It appears that this year is shaping up the same way. This week we have had numerous calls on young cotton with very high numbers of thrips. There have also been reports of Western flower thrips on cotton.
There have been a lot of questions recently about thrips control in peanuts. In general, thrips will not hurt peanut yields except in EXTREME situations. Peanut seedlings are relatively vigorous compared to most of the crops grown in Mississippi. Foliar insecticide applications, though rarely needed, should be based on plant injury rather than thrips numbers.
Yesterday (4/30), I had a call from a consultant who found about 20% infestation of 3-4 day old SWCB in Non-Bt, V6 stage corn in the Minter City area. There were places in the field that averaged 40-50% infestation, but overall was about 20%.
The 2012 Mississippi Agricultural Industry Council and Mississippi Seedsmen’s Association convention will be held again at beautiful Perdido Beach Resort in Orange Beach, Alabama, on July 24-July 28, 2012. This will be our 19th year at Perdido Beach Resort.
In the last couple of days there have been calls coming in about armyworms in wheat. It is not unusual for us to get armyworms in wheat in MS but this at least 2-3 weeks ahead of schedule compared to years past.
Word on the street is there will be many more corn refuge checks in 2012 in cotton growing regions. This is due to decreasing compliance over the last couple of years. However, it is getting so complicated that one grower
