The 2011 cotton crop is progressing nicely in spite of being somewhat late. Defoliation applications have taken place on some of the earliest planted cotton near Port Gibson as well as on small acreage near Benoit. In general, open bolls
Bacterial blight (or angular leaf spot) continues to be the hot topic in cotton production even at this late stage in the season. With continued temperatures between 86 and 97°F as well as scattered rainfall throughout much of the state it is likely that bacterial blight will continue to defoliate plants and infect bolls.
Southern MS On Monday and Tuesday (August 8 & 9) the soybean disease scouting crew made a tour through southern MS to scout soybean sentinel plots as well as commercial fields and kudzu. Little if any disease was identified; however,
Week ending August 7, 2011 Released: 3:00 P.M., August 8, 2011 : According to the National Agricultural Statistics Service in Mississippi, there were 5.6 days suitable for fieldwork for the week ending Sunday, August 7, 2011. Last week was hot
We are going on week 6 of a very high and sustained flight of bollworms in cotton, soybeans, and grain sorghum. The same control problems with pyrethroids we have had in soybeans have spilled over to grain sorghum and some
Bollworm counts were higher and tobacco budworm counts were lower this week in all regions. Southwestern corn borer counts were not compiled this week, but were generally much higher this week. Most corn is matured enough that little damage will occur
The reality of weed control in the Midsouth today is that the weed control season is never over. Because of glyphosate-resistant weeds, we are either in the process of killing weeds or we should be thinking about how to kill them.
Typically cotton aphids show up in MS around the end of June and begin to peak in early July. However, the last 2 years the bulk of our aphid pressure has been occurring around the end of July. The fungus, Neozygites fresenii, use to be fairly predictable occurring somewhere around the 4th – 10th of July in MS.
Currently, a trial is underway in Stoneville, MS to determine the impact of bacterial blight on the yield of some of the more commonly planted cotton varieties in MS.
Bollworm, budworm and beet armyworm trap catches remained similar to last week with moderate densities of bollworm in all areas of the state. Southwestern corn borer trap captures increased in most areas this past week, indicating the onset of the 3rd generation for the
The following is a very good report that Dr. Roger Leonard has recently put out on the use of ULV Malathion for late season control of tarnished plant bugs in cotton. We have also been testing this the last several years with good results but I would like to point out a couple of minor differences between MS and LA with respect to using ULV.
By Blake Layton: Fall armyworm populations were unusually heavy the past two years. They have been much lower so far this year, but this can change quickly.
Bollworm trap counts were higher this week throughout the state and tobacco budworm counts were higher in the Delta. Southwestern corn borer counts were relatively low this week, but started to rise this week in many areas, signaling the beginning
Soybean scouting continues throughout MS for foliar diseases. Over the past week to ten days, aerial web blight has been identified in several fields in eastern and northeastern MS. However, aerial blight has not been identified in the Delta and seems
As of now, I have had numerous reports of pyrethroid failures in soybeans targeting bollworms. Nearly everyone with soybeans at R1-R4 has bollworms at some level in the delta region of the state. So what is going on?
Irrigated Corn Verification Fields are nearly mature, but did require a final irrigation this week to provide ample moisture to sustain the crop to physiological maturity. Some slight root lodging also recently occurred, but otherwise harvest progress should commence soon. Late-planted dryland fields still have a long way to go and are under drought stress.
Over the past 7 days, numerous cotton fields have been determined to be infected with bacterial blight, caused by Xanthomonas axonopodis pv. malvacearum (formerly Xanthomonas campestris pv. malvacearum). In addition to the growing number of acres in MS having been
The soybean crop is advancing regardless of the extreme environmental conditions encountered throughout MS. At present, there are no foliar diseases of much consequence to report from either soybean sentinel plots or commercial fields. A little frogeye leaf spot has
Several fields of cotton in the Delta, as well as one field in Monroe County exhibiting symptoms of bacterial blight have been detected over the past 5 days. In addition, a significant acreage of cotton in Arkansas has been determined
Bollworm, tobacco budworm and beet armyworm pheromone trap captures remained similar to last week. Southwestern corn borer trap counts were lower this week, indicating that the second generation peak has past. One field in Leflore County had SWCB trap captures of
Regulations will go into effect after August 16, 2011 which will affect retailers, commercial applicators, custom blenders, re-fillers, and registrants of refillable pesticide containers. Essentially, these new regulations will affect those who use and handle mini-bulk pesticide containers, including growers.
Last week we started getting calls about flushing bollworm moths in soybean fields and a few fields were at or above threshold on larvae. This week was the turning point. As of today (7/15/11) we have started treating many fields.
Although many are aware of the issues that have been created by the appearance of four bract squares over the past few weeks, the magnitude of this issue warrants a final few words. First and foremost, four bract squares typically
This week we are starting to get some calls of the first soybean fields reaching threshold for bollworms. Bollworms (Corn Earworms) can be extremely devastating to soybeans because they feed directly on all fruiting structures. Many folks are also reporting
Over the last 10 days I have started getting calls about fall armyworms showing up in late planted soybeans. We see some of this every year, and it is primarily related to larvae moving off of a grass host after
