Southwestern corn borer numbers increased significantly in some areas this week. The highest numbers were 377 caught in Leflore County and 450 caught in Coahoma County. The current threshold in the 2016 Insect Control Guide suggests spraying when 50 moths are caught
In the Delta, trap catches of corn earworm and tobacco budworm were similar to last week, which is lower than average for this time of year. However, in the Northeastern Hills, tobacco budworm catches were higher while bollworm catches were
Much of the corn has reached the reproductive stages, while some is still in the vegetative stages. Several caterpillars, including fall armyworm and corn earworm, can infest corn, especially non-Bt corn, during both stages of development.
The 2016 MS ASA Summer Agronomy Tour will be Held June 29 in Vardaman, MS at the Penick Produce Co. This years tour will highlight all things Sweet Potato with topics ranging from Sweet Potato Production to Agritourism. The program can
Numerous fungicide trials were conducted during 2015 to determine the efficacy of fungicides on frogeye leaf spot. Included in this post are the majority of the soybean fungicide trials conducted at R2, R3, and R5 in Stoneville, MS on a FLS-susceptible soybean variety. A total 39 different product or product combinations were evaluated. A summary table is included to highlight a specific product and the trials that particular product was included in.
The entries contained in the MSU soybean OVT were screened for their sensitivity to the root-knot nematode during 2015. Contained within this blog post are the root galling responses of 133 entries as well as the yield from the RKN infested location.
Soybean diseases continue to be observed throughout the MS soybean production system. Over the past several weeks calls have centered on Septoria brown spot, Southern blight, and some limited questions regarding soybean rust.
Numerous questions over the past few weeks regarding fungicide product selection for the R3/R4 soybean application timing. Specific comments regarding the efficacy of products on frogeye leaf spot will be presented in an additional blog post. In this post, comments regarding application volume, fungicide application rates and decision on specific products.
To date, disease issues in the MS corn crop have remained somewhat quiet. Common rust has been the most prevalent disease as a result of wetter and cooler temperatures until the past 7 to 10 days. As of this morning (6/18/2016), southern rust has not been detected in MS.
Overall, southwestern corn borer traps remained low throughout the state. However, one trap in Leflore county captured 178 moths over a 7 day period. Although they do not appear to be widespread, this indicates that there may be pockets with
This week’s trap counts were similar to slightly higher than last week and last year for both bollworm and tobacco budworm. However, they are simlar to lower than long term average trap counts for this time of year. Corn is
Row rice or furrow irrigated rice is once again being investigated by the MSU Irrigation team as an alternative to conventional flooded rice production. Some of you may recall Dr. Joe Street and Dr. Ted Miller worked with Clarksdale’s Leon
Numerous instances have been observed this year where multiple growth stages of cotton occur in the same field and in some instances in the same row. This situation can present management challenges throughout the season. The following points are offered
All southwestern corn borer trapping locations did not report this week, but numbers were very low across the state. The highest numbers were in the south Delta, but still well below threshold with the highest number being 22 in one trap
Bollworm trap counts were somewhat lower this week in all counties except Lowndes. Tobacco budworm counts were slightly higher than last week, especially in the northeastern Hills region, but still not very high. Most corn is at or approaching pollination,
As much of our corn crop reaches tassel stage, it is apparent some fields are noticeably shorter than normal. This article will discuss what caused the corn to be short and whether or not it may reduce yield potential?
The Environmental Protection Agency has now authorized the use of Transform WG (sulfoxaflor) in Mississippi for control of tarnished plant bugs in cotton. For specific details see below.
This planting season has been challenging for a number of reasons. Cool, wet weather in early May gave way to very dry weather for several weeks thereafter in many areas of the state. Emergence problems have been observed in several areas
It is once again time to start posting pheromone trap results to assist you in making insect management decisions. This year we have 3-4 bollworm and 3-4 tobacco budworm pheromone traps in 5 Delta counties and 3 Northeastern Hill counties
Spring weather has proven challenging once again in 2016. Cool, wet conditions persisted into early May with planting not really getting started on a broad scale until late in the first week of May or the beginning of the second
There are many reasons why growers initiate early season irrigation. Activation and incorporation of dry fertilizers and herbicides have been one motivating factor this year. This year, it appears, growers are getting more familiar with utilizing soil moisture sensors as
Spider mites have been becoming more widespread over the last two weeks. Currently we have quite a few acres requiring treatment for spider mites and several that have already received an application. The hot dry weather we have been dealing with
