Foliar diseases continue to be observed throughout the Mississippi soybean production system. Low levels of frogeye leaf spot, Septoria brown spot and target spot have been frequently observed following the rainfall of the past two weeks. The first soybean rust on soybean was observed on Friday in Rankin County, MS on a single leaf in a field of R4/R5 soybeans.
What has happened with tarnished plant bug this year? That has been the million dollar question this year in cotton. Numerous consultants have told us that tarnished plant bug populations are lower than they have ever seen in their careers
Leaf blast has been observed in the MS rice crop for the better part of the last three weeks. In most cases, lesions were observed in areas of fields where the floodwater was less than four inches.
It looks like 2016 is shaping up to be another big year for fall armyworm in rice. As a reminder, our threshold in rice at this point in the season is 5 per 10 sweeps or when significant damage occurs.
Bollworm: We have had numerous reports of bollworm (soybean podworm corn earworm) moths being flushed and small larvae in cotton and soybeans over the last couple weeks. This past week seemed to be the turning point in soybean. Nearly anyone with
As the corn crop nears maturity, knowing when you can safely terminate irrigation timing, while optimizing yield potential is likely the most important decision you will face. In order to make this call, you need to estimate when the crop will reach maturity and how much moisture is present in your soil. This article outlines the steps needed to help make this process accurate and reliable.
Save for the appearance of a few common foliar diseases, the soybean disease situation remains fairly quiet. Septoria brown spot appears to be the most commonly occurring foliar disease. Scout fields for the presence of nematodes as well as stem diseases now to aid in next season’s decisions.
Cotton is blooming throughout Mississippi and a large portion of the crop is in good to excellent shape. In addition, fruit retention is very good in most cases. Once cotton begins to square and progresses into bloom, nutrient demands alter
Controlling GR Palmer amaranth on turnrows and ditchbanks has become a critical component to weed control.
The MSU-DREC Rice Producer Field Day will be held in conjunction with the annual Mississippi Farm Bureau Federation Summer Rice Grower Meeting this year on the morning of July 19 at the Capps Center in Stoneville. The MSU-DREC Rice Field Day will
Over the last couple weeks we have begun to get numerous calls about kudzu bugs infesting soybeans. Call are coming from all over the state. We no longer keep up with county level infestations but its safe to say they
Plant growth regulator use has become commonplace in cotton production over the past 30 years. However, as PGRs have become inexpensive, over application has occurred in some instances. While some areas of the state have enjoyed adequate rainfall this year,
Southwestern corn borer trap counts remained very high in some areas this week. The highest counts reported were in Sunflower, Quitman, and Coahoma counties.
The corn disease season continues to be somewhat quiet. Few if any foliar diseases have been observed throughout MS. Southern rust continues to be observed in western and southern MS; however, the disease has only be observed at low levels (one to two leaves) in all situations to date.
The 4th of July is very commonly associated with blooms appearing in Mississippi cotton. Some cotton is already blooming in the state while some will certainly be after the 4th of July. As cotton begins to set squares and eventually
Over the past several years, phytotoxicity has continued to be an important topic of conversation. Phytotoxicity can ultimately result following the application of numerous fungicide products. The specific symptoms associated with phytotoxicity can appear as interveinal chlorosis (either mild, moderate
The North Mississippi Research and Extension Center Field Day is scheduled for August 11, 2016 from 8 am to 1:30 pm with lunch provided.
Southwestern corn borer trap catches appear to be peaking this week. Several counties had individual traps with numbers at or near the current threshold and a couple well above threshold. As a reminder, the current threshold is 50 per trap
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
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.
