Southwestern Corn Borer Trap Counts – July 7, 2017
Field tour from 9 – 10:45 A.M. A field tour co-hosted with Dow AgroSciences/Phytogen will be conducted under the leadership of Drs. Dodds and Catchot. The program for the field tour is as follows: Phytogen Variety Overview – Kerry Saylors –
Pheromone trap catches this week were similar to last week and about average for this time of year. Tobacco budworm catches were much higher in Northeast MS than in the Delta region, so growers around Noxubee and Lowndes counties should
Bacterial blight of cotton has shown up in younger cotton in east and west MS. At present, 10 counties have been observed to contain bacterial blight cotton. To date (July 6), target spot has not been observed in the MS cotton crop.
The soybean disease situation continues to change throughout MS depending on growth stage situations in each field. Over the past week root diseases have been commonly observed. The first soybean rust of the season was observed in southwestern MS on kudzu.
Most of the cotton across the Delta is squaring now and plant bug applications have started to go out on most fields. We are catching a lot of plant bugs in flowering soybeans right now and the corn should start
Overall, southwestern corn borer trap numbers are increasing across the state. The thresholds in the control guide suggest treating 7 days after traps reach 50 moths for pre-tassel corn and 100 moths for tasseling corn. As a reminder, corn is safe
The fourth of July is typically associated with cotton blooms in Mississippi. While some fields are blooming or will do so in the next few days; a number of fields are still one to two weeks away from blooms appearing. In general,
The trap catches for both bollworm and tobacco budworm were similar to last week which are somewhat low for this time of year.
Increased reports of disease in the corn crop in MS have been made over the past week. Normally, as corn matures, the incidence and severity of corn diseases observed with increase. Presently, common rust, Diplodia leaf streak, northern corn leaf blight, and southern rust can all be observed in our corn production system; however, southern rust has only been observed on an extremely limited number of acres to this point in the season.
With the exception of Washington County bollworm traps, counts were similar to last week at levels near or below historic averages for both bollworm and tobacco budworm. Therefore worm pressure in susceptible crops should be typical for this time of
Over the past several years, fungicide pre-mix products have dominated the marketplace. Keeping up with the specific chemical classes within each product can present a challenge. Included in this blog post are some information to aid in making fungicide decisions.
Diagnosing common and southern rust in the field can oftentimes be difficult. Subtle differences between the two diseases can occur at different parts of the growing season as well as sections of the crop canopy.
Pheromone trap catches for bollworm moths were down for the week compared to the previous week. These numbers were also down somewhat from long term averages in both NE Mississippi and in the Delta. Tobacco budworm catches were low in
Limited soybean diseases have occurred throughout the MS soybean production system. Observations of Septoria brown spot and taproot decline have been quite common this season. Lesions that result from herbicide injury have also been commonly observed, but should not be cause for concern.
We have been getting several calls about adult rice water weevil adults and adult feeding in rice that has gone to flood. In fact, it appears that we are experiencing higher than normal populations this year in many areas of
Pheromone traps are up and recording data in a number of counties around Mississippi again this year. We will try to report the counts weekly to help you maximize your efficiency in scouting crops for worms. Pheromone traps can’t replace
Over the past week calls have started to be received regarding the automatic fungicide application in soybean. On-farm, large plot trials were conducted during 2015 and 2016 to assess the benefit of several different fungicide products and to reevaluate the automatic application timing. At present, we believe that a mixed mode of action fungicide, or one that provides more than one mode of action would be more beneficial than the stand-alone strobilurin (QoI) fungicide application that has become popular over the past decade.
There is no question that we are seeing increased tolerance to the seed treatments with tobacco thrips in cotton. We made an effort this year to encourage the use of acephate either in-furrow or as an overtreatment to the normal
In 2009 Redbanded stink bugs (RBSB) were treated in numerous areas of the state but numbers crashed in 2010. In 2013 there were a few fields treated and then they essentially were a non-issue until 2016. We have been hearing
The updated 2017 cotton maturity guide can be accessed using the link below. Keep in mind that maturity differences depicted in this guide are in an “everything else being equal” scenario. A number of factors can affect maturity including (but
It may be the understatement of the year to say that this spring has been very challenging for the agricultural community in Mississippi. Cool, wet weather seems to disappear then return, wind and sandblasting has caused severe damage to emerged
