Similar to most years when we have armyworms in wheat, there is the threat of having armyworms in seedling rice. We know of at least one rice field in Mississippi that was sprayed earlier this week. In general, damage from armyworms will not impact rice yields at this time of year unless they are beginning to reduce plant stand. This is especially true in hybrid rice planted at low seeding rates.
Bollworm trap catches were average this past week. While most traps caught 10-50 moths during the week, one trap near Indianola had 505 moths this past week. Tobacco budworm catches remain very low in both the Delta and NE Mississippi regions.
I have had several folks asking if there is a time when thrips should be treated in soybeans. Ordinarily thrips are not a problem in soybeans. Cotton and soybeans are completely different when it comes to how the plant can tolerate thrips. Soybeans are not nearly as sensitive to thrips as cotton and therefore can tolerate high numbers of thrips without yield loss.
I have gotten numerous calls about slugs this year in all crops but lately in cotton and soybean. Slug problems usually start on corn then soybeans then cotton in our area. This is only because we typically plant in this order. We have had isolated problems with slugs since 2004, some years worse than others.
As can be seen in the table below, trap counts this week were average in the hills and low in the Delta. This is in contrast to reports of bollworm larvae being abundant. More traps have been deployed this week,
Many of you have heard us talk about the declining efficacy of seed treatments against thrips throughout the winter meeting circuit. We started seeing the first signs of inadequate control about 4 years ago and the problem has seemed to get worse every year. Last year, most of the cotton in Mississippi was sprayed for thrips at least one time and many fields were sprayed multiple times, even behind a seed treatment. Until now, thiamethoxam (Cruiser, Avicta, or Acceleron N) has been impacted more than imidacloprid (Gaucho, Aeris, or Acceleron FI).
A little rice has started to go to flood in Mississippi this week and that means it is time to start thinking about rice water weevil. Overall, the majority of the crop is behind because of all of the rain that we have had across the Delta over the last several weeks. In general, the rice that is currently being flooded was some of the earliest planted. As a result, the early rice has endured a lot of rainfall and adverse conditions.
The dates for the 2014 Scout Schools have now been set. We will be providing detailed information on identification, biology, thresholds, and management of the major insect and disease pest of Mississippi row crops. These trainings can also be used to renew your insect and disease consultants license and CEU’s for Certified Crop Advisors will be provided at each. The meetings will also serve as In-Service training opportunities for MSU-ES agents as well. These trainings are great for the experienced and the inexperienced.
Our pheromone traps were monitored for the first time this week. Bollworm catches were high for this time of year with an average of 46 moths/trap caught in Noxubee county, 40 moths/trap in Lowndes county and 13 moths/trap in Oktibbeha county. Given
We have had several calls in recent days as news gets out about the EPA’s recent label changes for neonicotinoid insecticides. The intent is to offer greater protection for pollinators in and around crops where this class of insecticides may be applied. Basically, the new language forbids the use of these products while bees are foraging and until flowering is complete and all petals have fallen off the plants. There are a few exceptions if certain criteria are met.
Although very little, if any, cotton has been planted in the Delta, it is not too early to start thinking about managing tarnished plant bugs.
Recently several groups in Mississippi came together and developed then adopted a set of Cooperative Standards for row crop farmers and beekeepers in an effort to increase awareness of pollinator’s and create an environment where each could coexist while minimizing any
I have gotten numerous question about calibration of in-furrow rigs this year, so I am republishing an article I put up in the past that breaks calibrating pesticides down to a very easy understandable level. Proper calibration can mean the difference in control or failure of a product against the targeted pests and potentially thousands of dollars of savings to the grower.
Annual report of Mississippi Rice Promotion Board is now available online.
The 62nd annual Mid-South Farm & Gin Show will be held February 28 – March 1, 2014 at the Cook Convention Center in Memphis, TN. More than 400 exhibitors from more than 40 states will be on-hand showcasing the latest
Over the last several years we have seen a consistent response in wheat yield when a pyrethroid was used during the late winter months (late January-February). Often when this application goes out it is very difficult to find aphids at
The results from the Second Annual Future of Ag Graduate Student Competition are included in this post.
Over the last several years there has been a media blitz surrounding the decline in honey bee populations around the globe. It seems like the science changes daily as to cause of the problem. Most believe it is a complex
Attached please find the agenda for the Delta Ag Expo in Cleveland, MS. Make careful note that the dates of the meeting have changed from previous years due to a minor scheduling conflict with the Bolivar County Exposition Center.
Since 2011 we have seen a decline in efficacy of thiamethoxam treated cotton seed against tobacco thrips. This has led to the increase of foliar applications in mid-south cotton acres. Recently Syngenta has confirmed that populations in the mid-south region
The 2013 Row Crop Short Course will be held at the Bost Extension Center on the campus of Mississippi State University from December 2 – 4, 2013. The 2013 Row Crop Short Course will begin with an irrigation symposium hosted
The 3rd annual joint MEA/MAPPAN/MWSS annual meeting will be held next week at the Bost Extension Building in Starkville, MS next week. The dates of the meeting are Monday and Tuesday October 21-22. We have a very informative and exciting
This week marked the first reported appearances of sugarcane beetles in sweetpotato fields in Mississippi for the 2013 growing season. The sugarcane beetle is a relatively new pest of sweetpotato in Mississippi. However, in recent years, heavy sugarcane beetle populations
Since the last update several new counties have been added to the list in MS. Currently we 33 counties positive for Kudzu Bugs. Out of the 33 counties, 21 have positive finds in soybeans.
Virus-infected soybean material has been observed almost statewide this season. The high numbers of bean leaf beetles can be blamed for some of the observed viruses; however, bean leaf beetles are not the only insects that can vector soybean viruses between plants. This specific blog update presents information on the three most commonly encountered soybean viruses in the MS soybean production system.
